BACKGROUND: Determination of appropriate treatment options for adult osteochondritis dissecans is difficult, as most published papers on surgical osteochondritis dissecans treatment report outcomes in a population consisting of both adult and juvenile patients. PURPOSE: This study examines the outcomes of surgical procedures in patients with adult osteochondritis dissecans. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: The cohort included 46 adult patients (48 knees) with adult osteochondritis dissecans of the knee who had undergone surgical treatment (debridement, drilling, loose-body removal, arthroscopic reduction and internal fixation, microfracture, osteochondral allograft, or autologous chondrocyte implantation). The average patient age was 34 +/- 9.5 years (range, 20-49) and patients were followed for 4.0 +/- 1.8 years. The mean defect size was 4.5 +/- 2.7 cm(2). Outcomes were assessed via clinical assessment and established outcome scales, including the Lysholm, International Knee Documentation Committee (IKDC), Knee Injury and Osteoarthritis Outcome Score (KOOS), Tegner, Cincinnati, and Short Form-12. RESULTS: Statistically significant improvement (P < .05) was noted in all outcome scales, including Noyes, Tegner, Lysholm, IKDC, KOOS (subdivided into 5 categories including Pain, Symptoms, Activities of Daily Living, Sport, and Quality of Life), Short Form-12 Physical, and Short Form-12 Mental. Seven knees (14%) had clinical failure of the initial treatment and underwent a revision procedure at a mean follow-up of 14 months. Patients treated with arthroscopic reduction and internal fixation and loose-body removal demonstrated a statistically higher postoperative percentage score increase for the KOOS Sport (P = .008) and KOOS Quality of Life (P = .03) categories than those treated with an osteochondral allograft. CONCLUSION: Patients with adult osteochondritis dissecans of the knee, treated with surgical cartilage procedures, show durable function and symptomatic improvement at a mean 4.0 years of follow-up. Patients treated with arthroscopic reduction and internal fixation and loose-body removal demonstrated a greater improvement in outcome scores than those treated with osteochondral allograft.
