Objectives To assess the effectiveness of a modified tibial tubercle osteotomy as a treatment for arthroscopically diagnosed chondromalacia patellae. Methods A total of 47 consecutive patients (51 knees) with arthroscopically proven chondromalacia, who had failed conservative management, underwent a modified Fulkerson tibial tubercle osteotomy. The mean age was 34.4 years (19.6 to 52.2). Pre-operatively, none of the patients exhibited signs of patellar maltracking or instability in association with their anterior knee pain. The minimum follow-up for the study was five years (mean 72.6 months (62 to 118)), with only one patient lost to follow-up. Results A total of 50 knees were reviewed. At final follow-up, the Kujala knee score improved from 39.2 (12 to 63) pre-operatively to 57.7 (16 to 89) post-operatively (p < 0.001). The visual analogue pain score improved from 7.8 (4 to 10) pre-operatively to 5.0 (0 to 10) post-operatively. Overall patient satisfaction with good or excellent results was 72%. Patients with the lowest pre-operative Kujala score benefitted the most. Older patients benefited less than younger ones. The outcome was independent of the grade of chondromalacia. Six patients required screw removal. There were no major complications. Conclusions We conclude that this modification of the Fulkerson procedure is a safe and useful operation to treat anterior knee pain in well aligned patellofemoral joints due to chondromalacia patellae in adults, when conservative measures have failed.

BACKGROUND We describe using the scarf osteotomy to correct a recurrent hallux valgus deformity and lengthen the shortened first metatarsal in symptomatic iatrogenic first brachymetatarsia. METHODS Thirty-six lengthening scarf osteotomies were undertaken in 31 patients. Clinical and radiographic measures were taken pre and postoperatively. RESULTS Mean age at presentation was 53.4 years, and mean followup 3.9 years. The mean lengthening achieved was 4.9mm. All osteotomies united with no complications. The mean IMA reduction was 4.0° (p<0.001) and HVA 13.0° (p<0.001). The mean AOFAS score increase was 33.8 (p<0.001). There was a positive trend but no correlation (r=0.28) between amount of metatarsal lengthening and AOFAS score change. CONCLUSIONS We describe the largest lengthening scarf osteotomy series for recurrent hallux valgus with iatrogenic first brachymetatarsia. The results suggest the procedure is successful, with a low complication rate. We anticipate that restoring first metatarsal length and alignment may reduce biomechanical transfer metatarsalgia over time.

Brachymetatarsia of the fourth metatarsal, lengthening scarf osteotomy with bone graft

Ankit Desai; Surjit Lidder; Andrew R. Armitage; Samuel Rajaratnam; Andrew Skyrme

A 16-year-old girl presented with left fourth metatarsal shortening causing significant psychological distress. She underwent lengthening scarf osteotomy held with an Omnitech® screw (Biotech International, France) with the addition of two 1 cm cancellous cubes (RTI Biologics, United States). A lengthening zplasty of the extensor tendons and skin were also performed. At 6 weeks the patient was fully weight bearing and at one-year follow up, the patient was satisfied and discharged. A modified technique of lengthening scarf osteotomy is described for congenital brachymatatarsia. This technique allows one stage lengthening through a single incision with graft incorporation by 6 weeks.

The surgical anatomy of intra-abdominal prosthetic dislocation during hip arthroplasty

Hip replacement surgery remains one of the most successful and common operations in modern orthopaedics. Many surgical approaches to the hip have been described. A potential anatomical weakness exists between the hip joint and the retroperitoneal space. We describe this potential space, which lies superficial to iliopsoas and its importance in hip replacement surgery. The clinical relevance of this space is illustrated by 2 cases of retro-peritoneal migration of prosthetic femoral heads and the consequences of these.

Cycle to work scheme in the NHS

Christopher M. Jack; Max R. Edwards; Mirant Parikh; Samuel Rajaratnam

Byberg and colleagues’ study on mortality and physical activity convinces us of the importance of health promotion.1 Making the Department of Transport’s cycle to work scheme available to all NHS employees would yield enormous benefits. The scheme allows a tax exempt loan to purchase a bicycle and associated …

Traction osteophyte formation of the fifth metatarsal: ‘Speedway rider's foot’

A.D Skyrme; G.P.F Selmon; Samuel Rajaratnam; A.F.G Groom

Abstract We report a case series of patients with chronic traction osteophyte formation of the fifth metatarsal, secondary to speedway motorcycle racing. This previously unreported condition is almost ubiquitous in speedway cyclists and commonly causes forefoot pain. We advocate conservative management and patient education.
