中高年の早期変形性関節症に対する関節鏡単独手術の術後成績

抄録

Objective: The purpose of this study was to investigate postoperative outcomes in patients aged≥40 years old with medial meniscus (MM) tear complicated by early osteoarthritis (OA) that was treated with arthroscopic surgery alone.

Methods: The subjects were 13 patients (13 knees: 8 in males and 5 in females) with MM tear accompanied by Kellgren-Lawrence grade 0-Ⅱ early OA on plain radiography in the knee joint. All patients were treated with arthroscopic surgery alone at our hospital between January 2016 and December 2019. Evaluation items were clinical symptoms before and after surgery, MRI findings, preoperative plain radiographic findings, and intraoperative arthroscopic findings.

Results: The clinical outcome was favorable and meniscus tear-derived symptoms that were present before surgery improved in all patients after surgery. However, OA-derived symptoms remained in 2 knees.

Conclusion: We suggest that high tibial osteotomy may be an option for highly active patients with concomitant MM tear and symptoms of early OA.
