High rates of return to sport following management of osteochondritis dissecans of the femoral trochlea: A systematic review

Abstract

PurposeTo summarize management strategies and associated clinical outcomes in patients with osteochondritis dissecans (OCD) of the femoral trochlea.MethodsThree databases were searched from inception to 2 October 2023, for studies describing outcomes posttreatment for femoral trochlear OCD. The authors adhered to the preferred reporting items for systematic reviews and meta‐analyses and revised assessment of multiple systematic reviews guidelines as well as the Cochrane Handbook for Systematic Reviews of Interventions. Data on demographics, injury characteristics, and operative details were extracted. Outcomes included patient reported outcome measures (PROMs), complications, and revision and return to sport (RTS) rates.ResultsTwenty studies comprising 105 patients (119 knees) were included. Females comprised 10.1% (range: 0%–100%) of patients and the mean age of patients was 14.5 (range: 11–28) years. A total of 89 (74.7%) of knees received operative management, with 28 of 34 (82.4%) known open procedures being open reduction internal fixation (ORIF), and nine of 29 (31%) known arthroscopic procedures receiving arthroscopic reduction internal fixation (ARIF) or drilling. Lysholm and International Knee Documentation Committee scores in 20 patients each ranged from 93.4 to 100 and 74.7 to 96.6, respectively. The revision rate for operative procedures was 9.0%, and the overall RTS rate was 93.3%.ConclusionThere is very little high quality evidence investigating patients with femoral trochlear OCD lesions. Drilling, ARIF, and ORIF were the most common surgical options for this patient population. Patients treated with either nonoperative or operative management returned to sport at a high rate, and those requiring operative management had a low revision rate.Level of EvidenceLevel V.
