Introduction. Total knee replacement has been well-established form of treatment both for osteoarthritis and inflammatory arthritis. Both cemented and uncemented TKR have been used successfully. Since 1977 low contact stress (LCS) mobile bearing knee replacement has been in extensive use. Most of the intermediate and long term results reported are in osteoarthritis1–7. Though there are several studies reporting short term performance of TKR in rheumatoid arthritis8–19 there have been rare reports31 of intermediate to long-term performance of LCS uncemented TKR in rheumatoid arthritis. Methods. Retrospective, non-randomised and consecutive study. Case notes and radiological assessment done. Kaplan meyer survival analysis used. Radiological assessment between initial and final xrays done using T test statistics. Assessement done by two independent observer. Results. 108 knees in 67 patients are collected. 21 patients with 36 knees have died. Only 65 knees in 42 patients had both case notes and xrays which are included in this study. Of this 11 knees in 7 patients were dead. All 65 knees in 42 patients are sero-positive rheumatoid arthritis. Pre-operative bone loss was seen only in 4 knees. Bone loss was in the medial side in 3 knees (4,5 and 8mm respectively) and lateral in 1 knee (1 cm). None of these bone loss needed bone grafting or any special procedures. There was no subsidence in any of the 65 knees. Survival of uncemented LCS TKR in inflammatory arthritis patients is 100%. Aseptic failure is 0%. No infective failure. There is no significant change in the implant position. This is the longest follow for uncemented TKR in inflammatory arthritis ever reported in the literature. Conclusion and Discussion. In conclusion, our study has uniformity, as a single surgeon performed/supervised with senior trainees all the operations and all patients received the same level of post-operative care. Survival of LCS uncemented TKR in inflammatory arthritis patients is 100% up to 15years. This is the longest follow up in this patient population ever reported in the literature. Our study shows excellent survival and comparable to other cemented TKRs in this patient population reported in the literature. This study proves contrary to the general belief that uncemented TKR do poor in inflammatory arthritis due to osteoporotic bone

Introduction. The authors performed a short term prospective study of unicompartmental knee replacement (UKR) associated to patella-femoral arthroplasty (PFA) for the treatment of bicompartmental symptomatic knee arthritis. At the latest follow-up all the implants were matched to a similar computer assisted Total Knee Replacements (CAS-TKR) group implanted for the same indications. Hypothesis of the study was that this bicompartimental implants could achieve comparable outcomes to TKR with a more conservative surgery and a higher joint function. Materials and Methods. 19 cases of anteriomedial (12) or anterolateral (7) arthritis in 19 stable knees were prospectively involved in the study. All the knees underwent to a selective reconstruction using simultaneously both UKR and PFR using the same surgical technique. All bicompartmental implants were performed by the same surgeon. Surgical time, hospital staying and all intra and post operative complications were registered. At a minimum follow-up of 20 months, every single case was marched to a similar case where had been implanted a computer assisted cruciate retaining TKR. Criteria of matching were: sex, age, pre-operative range of motion and arthritis grade. In both the groups all the cases were assessed clinically using WOMAC, KKS and GIUM scores. All the knees were radiologically investigated using the same radiological protocol. Results. Intra operatively we did not registered any complication. No revision in both groups. The mean surgical time was 86 minutes (range: 78–121) in UKR+PFR group and 81 minutes (range: 71–112) in CAS-TKR group. There were no statistical significant differences in the hospital stay. No statistically significant difference was seen for the Knee Society, Functional and GIUM scores between the 2 groups. Statistically significant better WOMAC Function/Stiffness indexes were registered for the UKR+PFR group. CAS-TKR implants achieved a statistically better aligned mechanical axes. Conclusions. The results of this prospective short term prospective study suggest that UKR+PFR implant is a viable option for bicompartmental anteromedial arthritis at least as well as TKR but maintaining an higher level of function

Aim and Purpose of the study. The authors evaluate the efficacy of athrodiatasis as possible alternative to arthrodesis or arthroplasty in the treatment of ankle arthritis in young patients. They present the long term results (average 19 years) of a small series of patients (10 cases) treated with a monolateral transarticular external fixator associated to different open or athroscopic procedures. Material and Methodology. The patients have been revaluated with the Kitaoka scoring scale associated to the x-ray evaluation. The authors will compare these results with those reported for the same series at an early evaluation (2,5 y of follow up) and with those published in literature. Discussion. Arthrodiatasis of the ankle with distraction and movement of the joint under weightbearing can guarantee an intermittent Hydrostatic pressure that has a trophyc effect on residual cartilage. In 1995 a new interest in ankle distraction was promoted by a very active Duch group which in few years demonstrated that there was still space for this indication as alternative to the arthrodesis in very young and active patients because the functional and physical impairment, the pain and mobility of this joint can be improved also after the first year of follow up. Our good results with the same approach seems to confirm their conclusions after a long term follow –up even if there is no correlation between the functional and radiological findings. It is important to underline that frequently is necessary to associate to arthrodiatasis other ancillary arthroscopic or open procedures in order to optimise the results. Conclusion. Arthodiatasis as possible alternative to arthrodesis or arthroplasty in the treatment of ankle arthritis is still a valid option in selected cases because can guarantee good functional results even at a long term follow-up

Arthritis of the mid-foot is a common presentation to the foot and ankle clinic, resulting from primary (idiopathic), post-traumatic, or inflammatory joint degeneration. Treatment in the initial stages is conservative, with midfoot fusion regarded as the operative treatment of choice; however there is a paucity of comparative and patient reported data regarding outcomes. Patient reported outcome measures (PROMS), were prospectively collected from October-2015 to March-2018. Diagnoses were confirmed with image guided injection and initial management was conservative. In total, 66 patients were managed conservatively and 40 treated with mid-foot fusion. MOxFQ (Manchester Oxford Foot Questionnaire) and EQ-5D-3L (Euroqual) PROMS were collected pre-operatively, at 26 weeks and at 52 weeks. In the operatively managed group, the female:male ratio was 5.7:1, with a mean age of 61 (range 24–80), while in the conservatively managed group, the ratio was 2.1:1 with mean age 63 (range 29–86). In the surgically managed group, 88.2% of patients reported improvement in symptoms at 26 weeks and 88.9% at 52 weeks. This was greater than the conservatively managed group, in which 40.6% reported improvement at 26 weeks and 33.3% at 52 weeks. Mean MOxFQ improvement in the surgically managed group was +30.7 and +33.9 at 26 and 52 weeks respectively, and in the conservative group, +9.4 and +4.3, at 26 and 52 weeks. Similarly, favourable surgical outcomes were reported across all domains of EQ-5D-3L. This study has highlighted excellent early outcomes after surgical treatment and may represent promise for those patients for whom conservative management fails

The primary aim of this study was to compare the knee specific functional outcome of partial compared with total knee replacement (TKR) for the management of patellofemoral osteoarthritis.

Fifty-four consecutive Avon patellofemoral replacements were identified and propensity score matched to a group of 54 patients undergoing a TKR with patella resurfacing for patellofemoral osteoarthritis. The Oxford knee score (OKS), the Short Form (SF-) 12 and patient satisfaction were collected (mean follow up 9.2 years). Survival was defined by revision or intention to revise.

There was no significant difference in the OKS (p>0.60) or SF-12 (p>0.28) between the groups. The TKR group was significantly less likely to be satisfied with their knee (95.1% versus 78.3%, OR 0.18, p=0.03). Length of stay was significantly (p=0.008) shorter for the Avon group (difference 1.8 days, 95% CI 0.4 to 3.2). The 10 year survival for the Avon group was 92.3% (95% CI 87.1 to 97.5) and for the TKR group was 100% (95% CI 93.8 to 100). There was no statistical difference in the survival rate (Log Rank p=0.10).

The Avon patellofemoral replacement have a shorter length of stay with a functional outcome and satisfaction rate that is equal to that of TKR. The benefits of the Avon need to be balanced against the increased rate of revision when compared with TKR.

Introduction

Total leg muscle function in hip OA patients is not well studied. We used a test-retest protocol to evaluate the reproducibility of single- and multi-joint peak muscle torque and rapid torque development in a group of 40–65 yr old hip patients. Both peak torque and torque development are outcome measures associated with functional performance during activities of daily living.

Midfoot arthrodesis is the conventional surgical intervention for midfoot arthritis. Arthrodesis aims to stabilise, realign and fuse the affected joints, providing patients with improved pain and function. Current research neglects the measurement of patient reported outcomes. This study aimed to investigate objective, and patient reported outcomes of midfoot arthrodesis. The secondary aim was to identify variables predicting the development of non-union. An automated search of online patient records identified 108 eligible patients (117 feet). The rates of union, re-operations, and complications were calculated using radiographs and medical records. Logistic regression was used to model variables influencing the odds of non-union. All living patients were posted a Manchester Oxford Foot Questionnaire (MOx-FQ), a patient reported outcome assessment. Pre-operative MOx-FQ results were available in a minority of cases. Students t-test was used to compare pre- and post-operative MOx-FQ scores. The rate of union achieved was 74%. The rate of re-operations was 35%. The rate of complications was 14%. Bone grafts and staple fixation independently impacted the odds of non-union. Bone grafts decreased the odds of non-union, whilst staple fixation increased the odds. This finding agrees with the opinion of other researchers. We recommend the use of bone grafts, and the avoidance of fixation with staples. Previous attempts have been made to assess patient outcomes. However, this study is the first to use the MOx-FQ, a validated questionnaire. Therefore, this study establishes a baseline for improvements in patient reported outcomes

Sub-acromial decompression surgery (SAD) has been widely used to treat shoulder impingement. Its validity has been questioned in multi-centric clinical trials and dissatisfaction rates can be high (35%). It is difficult to predict which patients will benefit operatively as research into predictive factors is limited. The study aim was to conduct a root-cause analysis of reasons for dissatisfaction in a cohort of operated patients. All patients with SAD dissatisfaction in the local Upper Limb database between 2015-19 (n=74/296) formed our study cohort. Patients were scored on Oxford shoulder score (OSS), QuickDASH score, EQ-5D-3L (TTO+VAS) at weeks 26 and 52 post-operatively. Patients' clinical history, radiographs, consultation and operative notes were reviewed. 28% of patients were dissatisfied with surgery. Mean age =52.3±13.4 years with equal gender distribution. 87% were operated arthroscopically. 67% were in physically demanding occupations. There was a significant increase in OSS and QuickDASH at weeks 26 and 52 post-operatively (p<0.05), similar improvement was not noted in VAS pain score. Pain followed by stiffness were the main contributors of dissatisfaction. Multiple implicating factors were noted, the most common being acromio-clavicular joint arthritis (25.7%), suggesting concomitant pathologies as an additional cause for patient dissatisfaction. This is the first study to evaluate reasons for dissatisfaction following SAD. We noted high rates (28%) of dissatisfaction and a predilection for those involved in physically demanding occupations. We recommend meticulous pre-operative workup to identify co-existing pathologies and appropriate pre-operative counselling to improve outcomes in selected patients needing SAD following failure of conservative management

We aimed to determine the rate of and risk factors for post-traumatic osteoarthritis (PTOA) and total knee arthroplasty (TKA) requirement after operative management of tibial plateau fractures (TPF) in older adults. We conducted a retrospective cohort study of 182 operatively managed TPFs in 180 patients ≥60 years old over a 12-year period with minimum follow up 1 year. Data including patient demographics, clinical frailty scores, mechanism of injury, management, reoperation and mortality were recorded. Radiographs were reviewed for: Schatzker classification; pre-existing knee osteoarthritis (KOA); severe joint depression >15mm; and development of PTOA. Kaplan Meier survival analysis was performed. Regression analysis was used to identify risk factors for radiographic indication for TKA and actual TKA. Forty-seven percent were Schatzker II fractures. Radiographic KOA was present at fracture in 32.6%. Fracture fixation was performed in 95.6% cases and acute TKA in 4.4%. Thirteen patients underwent late TKA (7.5%). At five-years, 11.8% (6.0-16.7 95% CI) had required TKA and 20.9% (14.4-27.4 95% CI) had a radiographic indication for TKA. Severe joint depression and pre-existing KOA were associated with worse survival for endpoints radiographic indication for TKA and actual TKA. Severe joint depression (HR 2.49(1.35-4.61 95% CI), p=0.004), pre-existing KOA (HR 2.23(1.17-4.23), p=0.015) and inflammatory arthropathy (HR 2.4(1.04-5.53), p=0.039) were independently associated with radiographic indication for TKA. In conclusion, severe joint depression and pre-existing arthritis are independent risk factors for both severe PTOA and TKA after TPFs in older adults. These features should be considered as an indication for primary management with acute TKA

Introduction. Osteochondral lesions (OCLs) of the talus are a challenging and increasingly recognized problem in chronic ankle pain. Many novel techniques exist to attempt to treat this challenging entity. Difficulties associated with treating OCLs include lesion location, size, chronicity, and problems associated with potential graft harvest sites. Matrix associated stem cell transplantation (MAST) is one such treatment described for larger lesions >15mm2 or failed alternative therapies. This cohort study describes a medium-term review of the outcomes of talar lesions treated with MAST. Methods. A review of all patients treated with MAST by a single surgeon was conducted. Preoperative radiographs, MRIs and FAOS outcome questionnaire scores were conducted. Intraoperative classification was undertaken to correlate with imaging. Postoperative outcomes included FAOS scores, return to sport, revision surgery/failure of treatment and progression to arthritis/fusion surgery. Results. 58 MAST procedures in 57 patients were identified in this cohort. The mean follow up was 5 years. There were 20 females and37males, with a mean age of 37 years (SD 9.1). 22 patients had lateral OCLS were and 35 patients had medial OCLs. Of this cohort 32patients had previous surgery and 25 had this procedure as a primary event. 15 patients had one failed previous surgery, 9 patients had two, four patients had three previous surgeries and three patients had four previous surgeries. 12 patients had corrective or realignment procedures at the time of surgery. In terms of complications 3 patients of this cohort went on to have an ankle fusion and two of these had medial malleolar metal work taken out prior to this, 5 patients had additional procedures for arthrofibrotic debridements, 1 patient had a repeat MAST procedure, 1 additional patients had removal of medial malleolar osteotomy screws for pain at the osteotomy site, there were 2 wound complications one related to the ankle and one related to pain at the iliac crest donor site. Conclusion. MAST has demonstrated positive results in lesions which prove challenging to treat, even in a “ failed microfracture” cohort. RCT still lacking in field of orthobiologics for MAST. Longer term follow up required to evaluate durability

Arthrodesis of the 1st metatarsophalangeal joint (MTPJ) is a common procedure used for the treatment of end stage arthritis. We studied a cohort of patients who underwent an isolated 1st MTPJ Fusion for the treatment of hallux rigidus. Here we report the 10-year clinical outcomes, complication rate, requirement for further surgery and patient experience. All patients, who underwent an isolated 1st MTPJ Fusion for osteoarthritis from June 2008 until November 2011 were included. Demographics, clinical outcome data and subsequent procedures performed were collected from a departmental database (Bluespier). Patients were contacted and asked to complete the MOxFQ questionnaire and rate their satisfaction using pain, function and if they would undergo the surgery again. Mean follow up was 10.85 (range 9–12) years. A total of 161 patients (183 feet) underwent an isolated 1st MTPJ fusion during this time period. 156 of the feet showed a successful arthrodesis (85.2% fusion rate); 27 patients required revision surgery, 19 (10.4%) for a symptomatic non-union and 8 (4.4%) for mal-union. Those patients with co-morbidities (diabetes and gout) required revision earlier than those without (p<0.01). Average MOxFQ score was 16.6 (0–64) and 28 out of the 38 (73.6%) said they would have the operation again. Overall, the long-term results of the 1st MTPJ fusion had good outcomes with a successful fusion rate and minimal complications, both in line with the corresponding literature. In this series, fusion provided high patient satisfaction with the majority of patients opting to undergo fusion with the gift of hindsight

Cheilectomy is a recommended procedure for early stage osteoarthritis of the 1st metatarsophalangeal joint. Although improvement in symptoms has been reported in many studies, long term performance is not well understood. It is thought that significant numbers of patients require subsequent arthrodesis or arthroplasty. We report on a large cohort of patients receiving this procedure and on complications, and mid-term outcome. This is a retrospective study looking at all patients undergoing cheilectomy for hallux rigidus between November 2007 and August 2018. Departmental database was used to record outcome measures including: postoperative wound infection, patient reported improvement in pain and incidence of further surgical interventions like revision cheilectomy, conversion to arthrodesis and arthroplasty. Osteoarthritis was staged radiographically using PACS (Hattrup and Johnson classification). A total of 240 feet in 220 patients (20 bilateral surgeries) were included with 164 females (75%) and 56 males (25%), the median age being 55 years (range 22–90 years). Radiological assessment showed 89 stage 1 arthritis (42%), 105 stage 2 (50%), 17 stage 3 (8%) and 9 patients were excluded due to unavailable radiographs. 5 patients (2%) had superficial wound infections. There were 16 further surgeries (7%); 12 arthrodesis (5%), 3 revision cheilectomy and 1 conversion to arthroplasty. 157 patients were found to be pain-free at the latest post-operative visit (77%), 48 reported minimal pain (23%), 15 patients were excluded due to incomplete data. Cheilectomy appears to effectively reduce pain with low complication rates. Rates of conversion to arthrodesis/arthroplasty are lower than in many reported studies

High tibial osteotomy (HTO) is a common procedure for treating medial compartment knee arthritis. The main goal is to reduce knee pain by transferring weight-bearing loads to the relatively unaffected lateral compartment and thus delaying the need of total knee replacement (TKR) by slowing or stopping destruction of medial compartment. Between 2002 and 2010, 34 HTO's were carried out in 32 patients (Mean age 44.2). Results were reviewed in 23 patients with an average follow-up of 10.2 years (range 6–14 years). Oxford knee score (OKS) assessment was carried out on those patients. Of the remaining 11 patients, one was excluded, 2 were lost to follow-up, and 2 had died. Five cases had TKR at an average 8.8 years since having HTO. OKS results revealed nine cases (39.1percnt;) scored (40–48) which indicate satisfactory joint function and don't require treatment. Three cases (13percnt;) scored (30–39) indicating mild to moderate arthritis. Six cases (26.1percnt;), scored (20–29) indicating moderate to severe arthritis. Five cases (21.8percnt;) scored (0–19) indicating severe arthritis. Only five patients (14.7percnt;) had TKR (6–14) years after there HTO. The majority of cases had an OKS suggesting satisfactory joint function. Even those with scores suggesting moderate to severe arthritis were able to function normally for more than 6 years. The successful outcome of HTO can be maintained for more than 6–16 years. We conclude that HTO should be recommended for the treatment of medial compartment arthritis of the knee in young and active patients for symptomatic improvement and maintenance of activity levels

The aims of this study were to identify means to quantify coronal plane displacement associated with distal radius fractures (DRFs), and to understand their relationship to radial inclination (RI).

Aims

To investigate health-related quality of life (HRQoL) of older adults (aged ≥ 60 years) after tibial plateau fracture (TPF) compared to preinjury and population matched values, and what aspects of treatment were most important to patients.

Aims

The aim of this study was to report the three-year follow-up for a series of 400 patients with a displaced intracapsular fracture of the hip, who were randomized to be treated with either a cemented polished tapered hemiarthroplasty or an uncemented hydroxyapatite-coated hemiarthroplasty.

Aims

The aim of this study was to compare the functional and radiological outcomes and the complication rate after nail and plate fixation of unstable fractures of the ankle in elderly patients.

We report a cost-effectiveness analysis of Primary Total Ankle Replacements (TAR). In addition, we looked for factors that could be predictors of increased gain in Quality-Adjusted Life Years (QALYs). Pre-operative and six-month post-operative data for TAR was obtained over seven-and-a-half-years in NHS Lothian. The EuroQol general health questionnaire (EQ-5D-3L) measured health-related Quality of Life and the Manchester-Oxford Foot Questionnaire (MOXFQ) measured joint function. Predictors, tested for significance with QALYs gained, were pre-operative scores and demographic data including age, gender, BMI and Deprivation category. Continuous variables were assessed with Pearson correlation coefficients, Deprivation and BMI categories with Boxplots and gender with the Mann-Whitney U test. The 74-patient cohort [Mean age 68.03 (SD 8.61), 60.8% male] had 49% classed as obese or higher. Cost per QALY gained was £3841, rising to £9202 when annual 3.5% reduction in health gains and 1.9% revision rates were included. Lower pre-operative EQ-5D-3L index correlated significantly with increased QALYs gained (p <0.01), all other predictors returned insignificant results (p >0.05). Primary TAR has proven very cost-effective in treating end-stage ankle arthritis. Pre-operative EQ-5D-3L is the most promising predictor of QALYs gained identified
