The Diagnosis and Treatment of Femoral Intercondylar Notch Non-Bony Impingement Syndrome: 15 Cases Report / 中国运动医学杂志

ABSTRACT

Objective To summarize clinical features and explore diagnosis and treatment of femoral intercondylar notch non-bony impingement syndrome. Methods 15 patients of femoral intercondylar notch non-bony impingement syndrome were identified during arthroscopic operation of 115 patients (120 knees) with restricted knee joint extention during Oct 2004 to Dec 2007. Among these 15 patients, there were 3 cases of Bucket Handle Tear(BHT), 1 case of ACL's cyst, 3 cases of ACL tibial avulsion injury, 3 cases of synovial incarceration, and 5 cases of synovial chondroma. 9 patients were diagnosed by MRJ and 2 by X-ray before operation. All 15 patients were confirmed under arthroscopy. Results 15 patients( 15 knees) were operated and followed up for a period of 4～24 months, mean 13 months. Mean Lysholm score was 65(range, 41～75) before operation and 89(range, 75～100) after operation. Joint extension restrict was 5～25 degrees (mean 8.1 degree) before operation and 0 degree after operation. Conclusion Arthroscopy could accurately diagnose femoral Intercondylar notch non-bony impingement syndrome. Pre-operation MRI was helpful for diagnosis. If MRI and X-ray showed negative findings, diagnostic arthroscopic examination could be applied. Good subjective and objective effects could be achieved with arthroscopic operation.
