A comparison between medial meniscus repair, partial meniscectomy, and normal meniscus in anterior cruciate ligament reconstructed knees.
A clinical, radiographic, and scintigraphic comparative study was performed on 57 consecutive successful patellar tendon anterior cruciate ligament reconstructions for chronic laxity. Patients were divided into 3 matched groups according to the medial meniscal treatment. Group A included 18 patients with medial meniscal repairs; Group B, 19 patients with partial medial meniscectomies; and Group C, 20 patients with normal menisci (controls). The average followup was 55 months. At clinical examination, patients in Group B had more activity-related pain than those in Group C (p = 0.04). The anteroposterior weight-bearing views in extension showed more degenerative changes in the medial compartment in Group B than in the other 2 groups (Group A versus B, p = 0.01; Group C versus B, p < 0.001). Scintigraphy showed an increased uptake in the operated knee as compared with the normal side (11%), but no differences among the 3 study groups. The patients with partial meniscectomies had more pain and degenerative radiographically evident changes than the control group. Medial meniscal repair offers a better chance than partial meniscectomy to preserve the articular cartilage of the medial compartment. Bone homeostasis, as detected by bone scanning, remains slightly altered in successful reconstructions as compared with the opposite normal side.
