Abstract

Case: A 54-year-old woman developed persistent posterolateral knee pain 1 year after arthroscopic lateral meniscectomy. Serial magnetic resonance imaging obtained before each surgical intervention retrospectively demonstrated progressive enlargement of the fabella. Arthroscopy confirmed impingement between the fabella and the lateral femoral condyle. All-arthroscopic fabellectomy resulted in immediate symptom relief, with no recurrence at the 2-year follow-up.

Conclusion: This case highlights a potential relationship between altered load distribution after meniscectomy and progressive fabellar hypertrophy. Fabella syndrome should be considered in patients with persistent posterolateral knee pain after meniscectomy.

关节镜外侧半月板切除术后的Fabella综合征与一系列影像学表现：1例报告。

病例：一名54岁女性在关节镜下半月板外侧切除术后1年出现持续的膝后外侧疼痛。每次手术前获得的连续磁共振成像回顾性显示腓肠肌进行性扩大。关节镜检查证实腓骨与股外侧髁之间有撞击。全关节镜下腓肠肌切除术导致症状立即缓解，2年随访无复发。结论：本病例强调了半月板切除术后负荷分布改变与进行性腓骨肥厚之间的潜在关系。半月板切除术后持续膝后外侧疼痛的患者应考虑Fabella综合征。

期刊介绍： JBJS Case Connector helps improve patient care by providing the medical community with a journal that harnesses technology to provide information tools for discovery and reporting of unusual musculoskeletal problems, findings, treatment, and outcomes. Co-edited by Thomas W. Bauer, MD, PhD, and Ronald W. Lindsey, MD, JBJS Case Connector assists orthopaedic surgeons in the search for precedents, connections, and trends in their efforts to improve patient care. Using this unique journal, surgeons can find the commonalities between cases, benefit from the experience of their peers, and filter case information by many important variables in order to provide the best possible care for orthopaedic patients. This cross-referenced online journal includes thousands of orthopaedic case reports. It compiles symptoms, conditions, and demographic details to empower surgeons to find cases similar to theirs. Surgeons can mine the database to reveal emerging trends and identify patterns, distinguishing between truly rare cases and repeated, related single instances of a larger problem. The JBJS Case Connector Image Quiz feature provides interactive quizzes based on images from content published by JBJS and includes a discussion area for further exploration of ideas and concepts. The JBJS Image Quiz app for iPad and iPhone is available in the App Store. Contributions to JBJS Case Connector are welcomed from anywhere in the world and are considered on their merits. Articles must be written in English and should be submitted as outlined in the Instructions to Authors. All authors must abide by the JBJS ethics policies and all submissions to JBJS Case Connector are covered by the JBJS embargo policy.
