BACKGROUND: To date, reports of surgical treatment of spontaneous osteonecrosis of the knee (SPONK) refractory to non-operative treatment have primarily focused on knee arthroplasty. This report presents an overview of the characteristics of SPONK and reports our experience with joint-preserving surgical treatment of this condition. METHODS: Fifteen patients who had joint-preserving surgery after failed non-operative modalities were studied. These patients were treated at a single center between January 1998 and September 2006 with a combination of arthroscopy and core decompression, or osteochondral autograft transfers. RESULTS: Thirteen of the 15 knees (87%) had knee joint survival with a mean Knee Society Score of 81 points (range 45–100 points) at a mean follow-up of 40 months (range 9–120 months). Five of seven knees treated with core decompression had a successful clinical outcome. One of the patients who failed core decompression later underwent osteochondral autograft transfer, and eight of nine knees treated with this modality had a successful outcome. CONCLUSION: Overall, these results demonstrate that joint-preserving surgical treatment can successfully postpone the need for knee arthroplasty in selected patients with pre-collapse SPONK. |
