Abstract:
Objective To describe the special ramp lesion, which involves the capsulomeniscal region of posterior horn of medial meniscus and most commonly occurs in association with anterior cruciate ligament(ACL) injury, pre- and intra-operative diagnosis methods, arthroscopy repair technique and follow-up results of arthroscopy second-look & MR review. Methods From April 2002 to April 2005, 89 cases of ACL injury with ramp lesions are enrolled in this series, among them 85 need operation repairing. Arthroscopic ACL reconstruction with hamstring or B-PT-B autograft or allograft and all-inside medial meniscus repair through 2 posteromedial portals and transcondylar portal have been performed. Generally, the ramp lesion accounts for 26.7% of ACL injury, 30.5% for chronic and 19.5% for acute injury respectively. Results Of the repaired ramp lesion cases, 75 cases(88.2%) are available for follow-up, with the duration from 5 to 41 months (mean, 20.2 months). 25 cases underwent arthroscopic second-look and 21 cases received MR evaluation. The study include subjective symptom, clinical examination, and arthroscopic second-look as well as MR review. All of the repaired cases present normal subjective and objective evaluations, and all the 25 second-look cases show completely healing. Of the 21 MR follow-up cases, 18 completely healed, 3 partial healed. Conclusion About 1/3 ACL injuries are associated with medial meniscus ramp lesion, and the morbidity is higher in old injuries than acute injuries. For this combined lesion, one stage ACL reconstruction and meniscus repair was recommended. All-inside meniscus repair is a satisfactory technique for ramp lesion and can get high healing rate.
