Aim. The aim of this study was to report the long-term outcome and implant survival of the lateral resurfacing elbow (LRE) arthroplasty in the treatment of elbow arthritis. Patients and Methods. We reviewed a consecutive series of 27 patients (30 elbows) who underwent LRE arthroplasty between December 2005 and January 2008. There were 15 women and 12 men, with a mean age of 61 years (25 to 82). The diagnosis was primary hypotrophic osteoarthritis (OA) in 12 patients (14 elbows), post-traumatic osteoarthritis (PTOA) in five (five elbows) and rheumatoid arthritis (RA) in ten patients (11 elbows). The mean clinical outcome scores including the Mayo Elbow Performance Score (MEPS), the American Shoulder and Elbow Surgeons elbow score (ASES-e), the mean range of movement and the radiological outcome were recorded at three, six and 12 months and at a mean final follow-up of 8.3 years (7.3 to 9.4). A one sample t-test comparing pre and postoperative values, and survival analysis using the Kaplan–Meier method were undertaken. Results. A statistically significantly increased outcome score was noted for the whole group at each time interval. This was also significantly increased at each time in each of the subgroups (OA, RA, and PTOA). Implant survivorship was 100%. Conclusion. We found that the LRE arthroplasty, which was initially developed for younger patients with osteoarthritis, is an effective form of surgical treatment for a wider range of patients with more severe degenerative changes, irrespective of their cause. It is therefore a satisfactory alternative to total elbow arthroplasty (TEA) and has lower rates of complications in the subgroups of patients we have studied. It does not require activities to be restricted to the same extent as following TEA. Based on this experience, we now recommend LRE arthroplasty rather than TEA as the primary form of implant for the treatment of patients with OA of the elbow.

Aims

Return to sport following undergoing total (TKA) and unicompartmental knee arthroplasty (UKA) has been researched with meta-analyses and systematic reviews of varying quality. The aim of this study is to create an umbrella review to consolidate the data into consensus guidelines for returning to sports following TKA and UKA.

Aims

This study aimed to identify risk factors (patient, healthcare system, and socioeconomic) for mortality after hip fractures and estimate their relative importance. Further, we aimed to elucidate mortality and survival patterns following fractures and the duration of excess mortality.

Aims. The aim of this study was to evaluate the prosthesis characteristics and associated conditions that may modify the survival of total femoral endoprosthetic replacements (TFEPR). Patients and Methods. In all, 81 patients treated with TFEPR from 1976 to 2017 were retrospectively evaluated and failures were categorized according to the Henderson classification. There were 38 female patients (47%) and 43 male patients (53%) with a mean age at diagnosis of 43 years (12 to 86). The mean follow-up time was 10.3 years (0 to 31.7). A survival analysis was performed followed by univariate and multivariate Cox regression to identify independent implant survival factors. Results. The revision-free survival of the implant was 71% at five years and 63.3% at ten years. Three prostheses reached 15 years without revision. The mean Musculoskeletal Tumor Society score in the group was 26 (23 to 28). The mechanisms of failure were infection in 18%, structural failures in 6%, tumour progression in 5%, aseptic loosening in 2%, and soft-tissue failures in 1%. Prostheses used for primary reconstruction after oncological resections had lower infection rates than revision implants (8% vs 25%; p = 0.001). The rates of infection in silver-coated and non-silver-coated prosthesis were similar (17.4% vs 19.%; p = 0.869). The incidence of hip dislocation was 10%. Rotating hinge prosthesis had a lower failure rate than fixed hinge prosthesis (5.3% vs 11%). After Cox regression, the independent factors associated with failures were the history of previous operations (hazard ratio (HR) 3.7; p = 0.041), and the associated arthroplasty of the proximal tibia (HR 3.8; p = 0.034). At last follow-up, 11 patients (13%) required amputation. Conclusion. TFEPR offers a reliable reconstruction option for massive bone loss of the femur, with a good survival when the prosthesis is used as a primary implant. The use of a rotating hinge at the knee and dual mobility bearing at the hip may be adequate to reduce the risk of mechanical and soft-tissue failures. Infection remains the main concern and there is insufficient evidence to support the routine use of silver-coated endoprosthesis. Cite this article: Bone Joint J 2019;101-B:522–528

Aim. The primary aim of this retrospective study was to identify the incidence of heterotopic ossification (HO) following elective and trauma elbow arthroplasty. The secondary aim was to determine clinical outcomes with respect to the formation of heterotopic ossification. Patients and Methods. A total of 55 total elbow arthroplasties (TEAs) (52 patients) performed between June 2007 and December 2015 were eligible for inclusion in the study (29 TEAs for primary elective arthroplasty and 26 TEAs for trauma). At review, 15 patients (17 total elbow arthroplasties) had died from unrelated causes. There were 14 men and 38 women with a mean age of 70 years (42 to 90). The median clinical follow-up was 3.6 years (1.2 to 6) and the median radiological follow-up was 3.1 years (0.5 to 7.5). Results. The overall incidence of HO was 84% (46/55). This was higher in the trauma group (96%, 25/26) compared with the elective arthroplasty group (72%, 21/29) (p = 0.027, Fisher’s exact test). Patients in the trauma group had HO of higher Brooker class. The presence of HO did not significantly affect elbow range of movement within the trauma or elective groups (elective arthroplasty, Mann–Whitney U test, p = 0.070; trauma arthroplasty, p = 0.370, Mann–Whitney U test). Conclusion. HO after total elbow arthroplasty is seen more commonly than previously reported. We have reported a significantly higher rate of HO in TEAs performed for trauma than those performed electively. Cite this article: Bone Joint J 2018;100-B:767–71

Aims

Evidence exists of a consistent decline in the value and time that medical schools place upon their undergraduate orthopaedic placements. This limited exposure to trauma and orthopaedics (T&O) during medical school will be the only experience in the speciality for the majority of doctors. This review aims to provide an overview of undergraduate orthopaedic training in the UK.

The number of arthroplasties of the hip and knee is predicted to increase rapidly during the next 20 years. Accompanying this is the dilemma of how to follow-up these patients appropriately. Current guidelines recommend long-term follow-up to identify patients with aseptic loosening, which can occur more than a decade postoperatively. The current guidelines and practices of orthopaedic surgeons vary widely. Existing models take up much clinical time and are expensive. Pilot studies using ‘virtual’ clinics and advanced-practice physiotherapists have shown promise in decreasing the time and costs for orthopaedic surgeons and patients. This review discusses current practices and future trends in the follow-up of patients who have an arthroplasty. Cite this article: Bone Joint J 2018;100-B:6–10

Aims

The aim of this study was to assess medium-term improvements following total hip arthroplasty (THA), and to evaluate what effect different preoperative Oxford Hip Score (OHS) thresholds for treatment may have on patients’ access to THA and outcomes.

Aims. Arthroplasty for end-stage hallux rigidus (HR) is controversial. Arthrodesis remains the gold standard for surgical treatment, although is not without its complications, with rates of up to 10% for nonunion, 14% for reoperation and 10% for metatarsalgia. The aim of this study was to analyze the outcome of a double-stemmed silastic implant (Wright-Medical, Memphis, Tennessee, USA) for patients with end-stage HR. Methods. We conducted a retrospective review of 108 consecutive implants in 76 patients, between January 2005 and December 2016, with a minimum follow-up of two years. The mean age of the patients at the time of surgery was 61.6 years (42 to 84). There were 104 females and four males. Clinical, radiological, patient reported outcome measures (PROMS) data, a visual analogue score (VAS) for pain, and satisfaction scores were collected. Results. The survivorship at a mean follow-up of 5.3 years (2.1 to 14.1) was 97.2%. The mean Manchester Oxford Foot and Ankle Questionnaire (MOXFQ) scores improved from 78.1 to 11.0, and VAS scores for pain from 7/10 to 1.3/10. The rate of satisfaction was 90.6%. Three implants (2.8%) required revision; one for infection, one-month postoperatively, and two for stem breakage at 10.4 and 13.3 years postoperatively. There was a 1.9% reoperation rate other than revision, 23.1% of patients developed a minor complication, and 21.1% of patients had non-progressive and asymptomatic cysts on radiological review. Conclusion. We report a 97.2% survivorship at a mean follow-up of 5.3 years with this implant. We did not find progressive osteolysis, as has been previously reported. These results suggest that this double-stemmed silastic implant provides a predictable and reliable alternative with comparable outcomes to arthrodesis for the treatment of end-stage HR.

Aims. We performed a systematic review of the current literature regarding the outcomes of unconstrained metacarpophalangeal joint (MCPJ) arthroplasty. Materials and Methods. We initially identified 1305 studies, and 406 were found to be duplicates. After exclusion criteria were applied, seven studies were included. Outcomes extracted included pre- and post-operative pain visual analogue scores, range of movement (ROM), strength of pinch and grip, satisfaction and patient reported outcome measures (PROMs). Clinical and radiological complications were recorded. The results are presented in three groups based on the design of the arthroplasty and the aetiology (pyrocarbon-osteoarthritis (pyro-OA), pyrocarbon-inflammatory arthritis (pyro-IA), metal-on-polyethylene (MoP)). Results. Results show that pyrocarbon implants provide an 85% reduction in pain, 144% increase of pinch grip and 13° improvements in ROM for both OA and IA combined. Patients receiving MoP arthroplasties had a reduction in pinch strength. Satisfaction rates were 91% and 92% for pyrocarbon-OA and pyrocarbon-IA groups, respectively. There were nine failures in 87 joints (10.3%) over a mean follow-up of 5.5 years (1.0 to 14.3) for pyro-OA. There were 18 failures in 149 joints (12.1%) over a mean period of 6.6 years (1.0 to 16.0) for pyro-IA. Meta-analysis was not possible due to the heterogeneity of the studies and the limited presentation of data. Conclusion. We would recommend prospective data collection for small joint arthroplasties of the hand consisting of PROMs that would allow clinicians to come to stronger conclusions about the impact on function of replacing the MCPJs. A national joint registry may be the best way to achieve this. Cite this article: Bone Joint J 2017;99-B:100–6

Aims

This systematic review aims to compare the precision of component positioning, patient-reported outcome measures (PROMs), complications, survivorship, cost-effectiveness, and learning curves of MAKO robotic arm-assisted unicompartmental knee arthroplasty (RAUKA) with manual medial unicompartmental knee arthroplasty (mUKA).

Aims

Hip arthroplasty aims to accurately recreate joint biomechanics. Considerable attention has been paid to vertical and horizontal offset, but femoral head centre in the anteroposterior (AP) plane has received little attention. This study investigates the accuracy of restoration of joint centre of rotation in the AP plane.

Aims

The preoperative diagnosis of periprosthetic joint infection (PJI) remains a challenge due to a lack of biomarkers that are both sensitive and specific. We investigated the performance characteristics of polymerase chain reaction (PCR), interleukin-6 (IL6), and calprotectin of synovial fluid in the diagnosis of PJI.

Aims. Routine surveillance of primary hip and knee arthroplasties has traditionally been performed with office follow-up visits at one year postoperatively. The value of these visits is unclear. The present study aims to determine the utility and burden of routine clinical follow-up at one year after primary arthroplasty to patients and providers. Methods. All patients (473) who underwent primary total hip (280), hip resurfacing (eight), total knee (179), and unicompartmental knee arthroplasty (six) over a nine-month period at a single institution were identified from an institutional registry. Patients were prompted to attend their routine one-year postoperative visit by a single telephone reminder. Patients and surgeons were given questionnaires at the one-year postoperative visit, defined as a clinical encounter occurring at nine to 15 months from the date of surgery, regarding value of the visit. Results. Compliance with routine follow-up at one year was 35%. The response rate was over 80% for all questions in the patient and clinician surveys. Overall, 75% of the visits were for routine surveillance. Patients reported high satisfaction with their visits despite the general time for attendance, including travel, being over four hours. Surgeons found the visits more worthwhile when issues were identified or problems were addressed. Conclusion. Patient compliance with follow-up at one year postoperatively after primary hip and knee is low. Routine visits of asymptomatic patients deliver little practical value and represent a large time and cost burden for patients and surgeons. Remote strategies should be considered for routine postoperative surveillance primary hip and knee arthroplasties beyond the acute postoperative period.

During the years 1971 to 1975, 378 Charnley low-friction arthroplasties of the hip were performed on 278 patients with rheumatoid arthritis. The average age at operation was thirty-nine years. The follow-up time ranged from one to six years (mean two and a half years). Forty per cent of patients were receiving steroids at the time of operation. The most common complications were loosening of the prosthesis (3.4%), perforation of the femoral cortex and fracture. Deep infection occurred in 0.7%, dislocation in 0.7%, and thromboembolic episodes in 1.3%. Ninety-five per cent of patients were free of pain at follow-up compared to 84% who were severely handicapped by pain before operation. In addition, the increased mobility in 98.5% of patients and their improved independence makes hip replacement a recommendable procedure in these patients

Aims. The COVID-19 pandemic led to a national suspension of “non-urgent” elective hip and knee arthroplasty. The study aims to measure the effect of the COVID-19 pandemic on total hip arthroplasty (THA) and total knee arthroplasty (TKA) volume in Scotland. Secondary objectives are to measure the success of restarting elective services and model the time required to bridge the gap left by the first period of suspension. Methods. A retrospective observational study using the Scottish Arthroplasty Project dataset. All patients undergoing elective THAs and TKAs during the period 1 January 2008 to 31 December 2020 were included. A negative binomial regression model using historical case-volume and mid-year population estimates was built to project the future case-volume of THA and TKA in Scotland. The median monthly case volume was calculated for the period 2008 to 2019 (baseline) and compared to the actual monthly case volume for 2020. The time taken to eliminate the deficit was calculated based upon the projected monthly workload and with a potential workload between 100% to 120% of baseline. Results. Compared to the period 2008 to 2019, primary TKA and THA volume fell by 61.1% and 53.6%, respectively. Since restarting elective services, Scottish hospitals have achieved approximately 40% to 50% of baseline monthly activity. With no changes in current workload, by 2021 there would be a reduction of 9,180 and 10,170 for THA and TKA, respectively. Conversely, working at 120% baseline monthly output, it would take over four years to eliminate the deficit for both TKA and THA. Conclusion. This national study demonstrates the significant impact that COVID-19 pandemic has had on overall THA and TKA volume. In the six months after resuming elective services, Scottish hospitals averaged less than 50% normal monthly output. Loss of operating capacity will increase treatment delays and likely worsen overall morbidity. Cite this article: Bone Joint Open 2021;2(3):203–210
