Tendoscopy in the treatment of peroneal tendon disorders is becoming an increasingly safe, reliable, and reproducible technique. Peroneal tendoscopy can be used as both an isolated procedure and as an adjacent procedure with other surgical techniques. The aim of our study was to review all peroneal tendoscopy that was undertaken at the AOC, by the senior authors (IGW, SH), and to determine the safety and efficacy of this surgical technique. Methods. From 2000 to 2017 a manual and electronic database search was undertaken of all procedures by the senior authors. Peroneal tendoscopy cases were identified and then prospectively analysed. Results. 51 patients (23 male, 28 female) were identified from 2004–2017 using a manual and electronic database search. The mean age at time of surgery was 41.5 years (range 16–83) with a mean follow-up time post operatively of 11.8 months (range 9–64 months). The main indications for surgery were lateral and/or postero-lateral ankle pain and lateral ankle swelling. The majority of cases showed unstable peroneal tendon tears that were debrided safely using tendoscopy. Of the 51 patients, 23 required an adjacent foot and ankle operation at the same time, 5 open and 17 arthroscopic (12 ankle, 5 subtalar). Open procedures included 2 first ray osteotomies, 2 open debridements of accessory tissue, one PL to PB transfer. One patient also had an endoscopic FHL transfer. Complication rates to date have been low: 2 superficial wound infections (4%) and one repeat tendoscopy for ongoing pain. A small proportion of patients with ongoing pain were treated with USS guided steroid injections with good results. Conclusion. Our series of peroneal tendoscopy has a low complication rate with high patient satisfaction at discharge. Results of tendoscopic treatment are similar to open techniques, however its advantages make tendoscopic procedures an excellent method to treat peroneal tendon disorders

Background. We compared platelet rich plasma (PRP) injection to cortisone (40mg triamcinolone) injection in the treatment of chronic plantar fasciitis resistant to traditional nonoperative management. The aims were to compare early and long term efficacy of PRP to that of Steroid (3, 6 and 12 months after injection). Methods. 60 heels with intractable plantar fasciitis with failed conservative treatment were randomized to either PRP or Steroid injection. All patients were assessed with Roles-Maudsley (RM) Score, Visual Analogue Score (VAS) for pain and the American Orthopaedic Foot and Ankle Society (AOFAS) score. Data was collected prospectively on the cohort, pre-treatment, at 3, 6 and 12 months post injection. The mean scores of the two groups were compared using Student t test. Results. Pre-injection, the two groups were well matched with no statistically significant difference in the values. At 3 months, all three outcome scores in both groups had significantly improved from their pretreatment level with no significant difference between the groups (PRP: RM 3.7 to 2.0, VAS 8.3 to 3.5, AOFAS 58 to 84; Steroid: RM 3.6 to 1.9, VAS 8.3 to 2.8, AOFAS 57 to 86). At 6 months, improvement was maintained in both groups with no significant difference between groups (PRP: RM 2.1, VAS 3.7, AOFAS 89; Steroid: RM 2.2, VAS 3.3, and AOFAS 84). At 12 months, all outcome measures were significantly better for the PRP group as response in the steroid group had deteriorated (PRP: RM 1.9, VAS 3.3 and AOFAS 89; Steroid: RM 2.6, VAS 5.1 and AOFAS 77: p = 0.008, 0.02 and 0.002 respectively). Conclusions. PRP is better for the treatment of chronic plantar fasciitis as compared to steroid. It shows no statistical difference in effectiveness early on, but unlike steroid, its effectiveness does not wear off with time, making it more durable

Aims. The pathogenesis of intraneural ganglion cysts is controversial. Recent reports in the literature described medial plantar intraneural ganglion cysts (mIGC) with articular branches to subtalar joints. The aim of the current study was to provide further support for the principles underlying the articular theory, and to explain the successes and failures of treatment of mICGs. Patients and Methods. Between 2006 and 2017, five patients with five mICGs were retrospectively reviewed. There were five men with a mean age of 50.2 years (33 to 68) and a mean follow-up of 3.8 years (0.8 to 6). Case history, physical examination, imaging, and intraoperative findings were reviewed. The outcomes of interest were ultrasound and/or MRI features of mICG, as well as the clinical outcomes. Results. The five intraneural cysts followed the principles of the unifying articular theory. Connection to the posterior subtalar joint (pSTJ) was identified or suspected in four patients. Re-evaluation of preoperative MRI demonstrated a degenerative pSTJ and denervation changes in the abductor hallucis in all patients. Cyst excision with resection of the articular branch (four), cyst incision and drainage (one), and percutaneous aspiration/steroid injection (two) were performed. Removing the connection to the pSTJ prevented recurrence of mIGC, whereas medial plantar nerves remained cystic and symptomatic when resection of the communicating articular branch was not performed. Conclusion. Our findings support a standardized treatment algorithm for mIGC in the presence of degenerative disease at the pSTJ. By understanding the pathoanatomic mechanism for every cyst, we can improve treatment that must address the articular branch to avoid the recurrence of intraneural ganglion cysts, as well as the degenerative pSTJ to avoid extraneural cyst formation or recurrence.

Aims

This scoping review aims to identify patient-related factors associated with a poorer outcome following total ankle arthroplasty (TAA).

Background:. Avascular necrosis (AVN) of the talus is a painful condition caused by trauma, steroids, alcoholism and haematological disorders. It is difficult to treat and at present there is insufficient evidence in favour of any particular strategy. The aim of operative therapy should be to relieve symptoms, maintain the normal architecture of the talus and treat associated arthritis. Small case series have described early core decompression, retrograde tibiotalocalcaneal arthrodesies and open tibio-calcaneal arthrodesis. Open procedures risk further talar collapse by disrupting its blood supply, and tibiotalocalcanal fusion sacrifices both the ankle and subtalar joints. The hypothesis is that arthroscopic ankle fusion relieves symptoms of AVN talus while preserving the subtalar joint and preventing further collapse. Methods:. A case study was performed of 16 patients with AVN who underwent arthroscopic ankle fusion at the Nuffield Orthopaedic Centre, Oxford, UK between 1998 and 2012. Clinical notes, radiographs and MRI was used to investigate the cause, co-morbidities and treatment outcomes following arthroscopic ankle fusion. Our primary outcome was fusion rate. Secondary outcomes included peri-operative complications, ongoing pain and subsequent operative intervention. Results:. The average age at the time of operation was 53.5 years (range 17 to 69). The presumed causes of AVN talus were steroids (3 patients), trauma (3 patients), haematological (2 patients), and alcoholism. The aetiology was unknown in 7 patients. Clinical and radiological fusion at the ankle joint was confirmed in 14/16 patients (2 were followed elsewhere). 11 patients were satisfied with the result at discharge, reporting no post operative complications. 3 patients had ongoing pain. 2 patients reported metalware irritation. 2 patients underwent a subsequent subtalar fusion. Conclusions:. Arthroscopic ankle fusion is a safe and reliable treatment of symptomatic AVN talus. It is a minimally invasive procedure potentially improving blood supply to the the talus and sparing the subtalar joint

Aims

The Cartiva synthetic cartilage implant (SCI) entered mainstream use in the management of first metatarsophalangeal joint (MTPJ) arthritis following the positive results of large trials in 2016. Limited information is available on the longer-term outcomes of this implant within the literature, particularly when independent from the originator. This single-centre cohort study investigates the efficacy of the Cartiva SCI at up to five years.

Aims

This study aimed to compare the outcomes of two different postoperative management approaches following surgical fixation of ankle fractures: traditional cast immobilization versus the Early Motion and Directed Exercise (EMADE) programme.

Aims

The aim of this study was to compare the longer-term outcomes of operatively and nonoperatively managed patients treated with a removable brace (fixed-angle removable orthosis) or a plaster cast immobilization for an acute ankle fracture.

Introduction:. Symptomatic treatment of ankle osteoarthritis (OA) with corticosteroid injections is well established. Hyaluronic acid is also reported as an effective symptomatic treatment for ankle OA but these two treatments have not been compared directly. Methods:. A prospective randomised controlled trial in patients with symptomatic ankle osteoarthritis. Twenty patients per group were required based on a significance level of 0.05, and a drop out rate of 5%. Patients were blindly allocated to the treatment or control group. Injections were carried out by the clinician in the outpatient department. Treatment group received Ostenil 20 mg and control group received Depomedrone 40 mg (both as single injections). The treatment arm was allocated by computer generated block randomization to match treatment allocation with grade of arthritis. The primary outcome measure was the change in Visual Analogue Scale (VAS) pain score at 6 months. Secondary outcome was the change in AOFAS score at 6 months. Research ethics committee approval was obtained. Results:. A total of 42 patients were recruited of which 38 completed the study. Male recruits predominated (79%; 33 recruits). More than 70% had radiographic OA of grade 3 or more. Both groups demonstrated statistically significant improvements in VAS at weeks 3, 6, and 3 months over baseline, but the Ostenil group faired better at 6 months follow-up. (difference in VAS scores of 3.5 Ostenil VAS − 4; Steroid VAS − 7.5; Mann Whitney test (p<=0.05). There was no statistical difference in AOFAS scores between both groups at baseline and follow-up (p=0.48, Mann Whitney test). No complications noted. 30% of patients have had their surgical procedures delayed for 6 month post injection. Conclusion:. The Ostenil group revealed similar clinical efficacy to steroid group, however the benefits provided by Ostenil lasted longer. Ostenil provided sufficient mid-term pain-relief whilst patient awaits further definitive intervention

Aims

Although absorbable sutures for the repair of acute Achilles tendon rupture (ATR) have been attracting attention, the rationale for their use remains insufficient. This study prospectively compared the outcomes of absorbable and nonabsorbable sutures for the repair of acute ATR.

Introduction. Injections are used to treat a wide variety of pathologies. Our aim was to evaluate the efficacy and safety of foot and ankle injections in our clinic. Materials and methods. We performed a retrospective review of notes and a telephone questionnaire audit into the clinical outcome of all patients who underwent an injection of the foot or ankle in a year. All procedures were performed in an out-patient setting by a consultant musculoskeletal radiologist using either ultrasound or X-ray guidance, with a minimum of two year follow-up. According to the pathology treated, the type of injection included depomedrone, hyaluronic acid and high volume saline injections. Results. Overall 410/446 (92%) patients reported a significant improvement in symptoms and 227 (62%) reported complete resolution of their pain, with 127 (28%) remaining asymptomatic at two year follow-up. The mode time of recurrence of pain was three months. 59 (13%) underwent a further injection and 102 (23%) underwent operative intervention within the follow-up period. There were no reported infections. Complications occurred in two percent of patients, including steroid flare, pain and plantar plate ruptures. Conclusion. Injections are a safe and effective option for treating a variety of foot and ankle conditions and reduce the need for surgery. They are particularly effective for the treatment of ankle soft tissue impingement. They appear ineffective in providing significant improvement in pain for longer than three months in conditions such as plantar fasciitis and hallux rigidus

Aims

A multicentre, randomized, clinician-led, pragmatic, parallel-group orthopaedic trial of two surgical procedures was set up to obtain high-quality evidence of effectiveness. However, the trial faced recruitment challenges and struggled to maintain recruitment rates over 30%, although this is not unusual for surgical trials. We conducted a qualitative study with the aim of gathering information about recruitment practices to identify barriers to patient consent and participation to an orthopaedic trial.

Introduction. Bone marrow oedema syndrome (BMES) of the foot and ankle is an uncommon and often misdiagnosed condition. It is usually thought to be a benign self limiting condition, without any sequelae. However, it can cause disabling pain for a prolonged period of time. Materials and Methods. We retrospectively reviewed 8 patients with the diagnosis of BMES. There were 6 males and 2 females with an average age of 51 years (38–63 years). All patients had acute onset of severe pain in the foot without any history of trauma. None of the patients had history of excessive alcohol or steroid intake. 5 patients (63%) had bilateral involvement of migratory nature. All patients had characteristic features on MR scans, with involvement of 3 or more bones in the foot. Results. All patients had their limbs immobilised in a below knee cast and asked to mobilise non weight bearing for 6–8 weeks. Thereafter, they were allowed to mobilise with a pneumatic walker, increasing weight bearing as pain allowed. The walker was discarded at an average of 26 weeks. All 8 patients had complete relief of pain after an average of 14 months (4–22 months). All were able to return to their work environment but 2 complained of occasional aching and swelling of their feet, at the end of their shift at work. 2 patients were treated with bisphosphonates and 2 had targeted local anaesthetic injections with good pain relief. None were treated with Iloprost. Conclusions. BMES affecting the foot and ankle is an uncommon condition. Symptoms tend to be prolonged and may result in chronic swelling and aching around the ankle. Symptoms do tend to improve with time with or without intervention

Background. The aim of this prospective study was to assess the effectiveness of a single ultrasound-guided steroids injection in the treatment of Morton's neuromas and whether the response to injection correlates with the size of neuroma. Methods. Forty three patients with clinical features of Morton's neuroma underwent ultrasound scan assessment. Once the lesion was confirmed in the relevant web space, a single corticosteroids injection was given using 40 mg Methylprednisolone along with 1% Lidocaine. All scans and injections were performed by a single musculoskeletal radiologist. Patients were divided into two groups based on the size of the lesion measured on the scan. Group 1 included patients with neuromas of 5mm or less and Group 2 patients had neuromas larger than 5mm. The Visual Analogue Scale (Scale:0 to 10), the American Orthopaedic Foot and Ankle Society score (AOFAS) and the Johnson satisfaction scale were used to assess patients prior to injection and then at 6 weeks, 6 months and 12 months following the injection. Results. Thirty nine patients had confirmed neuromas. Group 1 (lesion ≤5mm) included 17 patients (mean age, 30 years) (7 males, 10 females) and Group 2 (lesion >5mm) had 22 patients (mean age, 33 years) (8 males, 14 females). VAS scores, AOFAS scores and Johnson scale improved significantly in both groups at 6 weeks (p < 0.0001). At 6 months post-injection, this improvement remained significant only in group 1 with regards to all scores (p < 0.001). At 12 months, there was no difference between both groups and outcome scores nearly approached pre-injection scores. The need for surgical treatment for persistent symptoms was similar in both groups (p = 0.6). Conclusion. A single ultrasound-guided corticosteroids injection offers generally a short-term pain relief for symptomatic Morton's neuromas. The effectiveness of the injection is likely to be more significant and long-lasting for lesions smaller than 5mm

Manipulation of the metatarsophalangeal joint and injection with steroid and local anaesthetic are widely practised in the treatment of hallux rigidus, but there is little information on the outcome. We report the results of this procedure carried out on 37 joints, with a minimum follow-up of one year (mean, 41.2 months). Patients with mild (grade-1) changes gained symptomatic relief for a median of six months and only one-third required surgery. Two-thirds of patients with moderate (grade-2) disease proceeded to open surgery. In advanced (grade-III) hallux rigidus, little symptomatic relief was obtained and all patients required operative treatment. We recommend that joints are graded before treatment and that manipulation under anaesthetic and injection be used only in early (grades I and II) hallux rigidus

Aims

In the context of tendon degenerative disorders, the need for innovative conservative treatments that can improve the intrinsic healing potential of tendon tissue is progressively increasing. In this study, the role of pulsed electromagnetic fields (PEMFs) in improving the tendon healing process was evaluated in a rat model of collagenase-induced Achilles tendinopathy.

Aims

The aim was to compare long-term patient-reported outcome measures (PROMs) after operative and nonoperative treatment of acute Achilles tendon rupture in the context of a randomized controlled trial.

Aims

Total ankle arthroplasty (TAA) has become the most reliable surgical solution for patients with end-stage arthritis of the ankle. Aseptic loosening of the talar component is the most common complication. A custom-made artificial talus can be used as the talar component in a combined TAA for patients with poor bone stock of the talus. The purpose of this study was to investigate the functional and clinical outcomes of combined TAA.

Aims

We hypothesized that there is no difference in the clinical and radiological outcomes using local bone graft versus iliac graft for subtalar distraction arthrodesis in patients with calcaneal malunion. In addition, using local bone graft negates the donor site morbidity.

Objectives

Inflammation of the retrocalcaneal bursa (RB) is a common clinical problem, particularly in professional athletes. RB inflammation is often treated with corticosteroid injections however a number of reports suggest an increased risk of Achilles tendon (AT) rupture. The aim of this cadaveric study was to describe the anatomical connections of the RB and to investigate whether it is possible for fluid to move from the RB into AT tissue.
