The aim of this study is to document the outcome of a large cohort of patients treated with the Bereiter trochleoplasty with between 1 and 12 years of follow up. 215 consecutive cases in 186 patients were recorded prospectively. All patients were offered yearly clinical and radiological review. PROMs were recorded including the IKDC, OKS, Kujala and SF-12. Patients unable to attend clinic were assessed with PROMS and radiographs from their local institutions where possible. There were 133 females and 53 males, with a mean age of 21 (14–38). There were no infections and only 6 patients reported further dislocations. There was one flap breakdown and no identified cases of secondary osteoarthritis. PROMs were available for 194 cases in 167 patients (90% follow up). 84% of patients were satisfied, 87% felt their symptoms had improved and 69% had gone back to sport. All scores improved (all p<0.001) except for the SF-12 mental score (p=0.42), with averages comparable to the results of MPFL reconstruction. Good outcomes were observed despite the difficult patient population in which these cases were performed. The Bereiter trochleoplasty is an effective method of treating recurrent patella instability in patients with severe
This study is a prospective analysis of clinical outcome in 201 consecutive patients treated with medial patellofemoral ligament reconstruction using an autologous semitendinosus graft between October 2005 and January 2011. Patients received pre and post-operative clinical evaluation, radiological assessment and outcome scoring systems. 193 patients (92 male, 119 female) underwent 211 procedures, with mean age 26 (16–49) and follow-up 16 months (6–42 months). Indications were atraumatic recurrent patella dislocation (68%), traumatic recurrent dislocation (22.8%), instability (5%), single dislocation (2.7%) and anterior knee pain (1.4%).
