Abstract:
Objective To investigate arthroscopic characteristics and minimally invasive treatment of meniscal injuries in osteoarthritic knees. Methods Sixty-eight cases of meniscal injuries in osteoarthritic knees were divided into four types according to arthroscopic characteristics of meniscal tears and involvement degree of the synovium and the cartilage: Type Ⅰ: limited meniscal injuries; Type Ⅱ: Limited injuries combined with abrasive injuries; Type Ⅲ: injuries of the most part of the meniscus, loose meniscus; Type Ⅳ: abraded meniscus combined with partial or mostly partial absence. Corresponding arthroscopic procedures were performed. Results Among the 68 cases, there were 10 cases of the Type Ⅰ injuries, 20 cases of the Type Ⅱ, 27 cases of the Type Ⅲ, and 11 cases of the Type Ⅳ, respectively. For the Type Ⅰ injuries, arthroscopic meniscal suture was performed in 4 cases and partial arthroscopic meniscectomy was performed in 6 cases. For the Type Ⅱ injuries, arthroscopic partial meniscectomy was performed in 18 cases and subtotal meniscectomy was performed in 2 cases. For Type Ⅲ injuries, arthroscopic lavage and debridement was performed in 1 case, arthroscopic partial meniscectomy in 5 cases, subtotal meniscectomy in 16 cases, and total meniscectomy in 5. For Type Ⅳ injuries, arthroscopic subtotal meniscectomy was performed in 2 cases and total meniscectomy in 9 cases. A follow-up was carried out for 6~52 months (mean, 22 months). There were 7 cases of pain after vigorous activities (Type Ⅱ: 1 case; Type Ⅲ: 2 cases; Type Ⅳ: 4 cases), 1 case of locking knee (Type Ⅲ), and 2 cases of limitation of knee flexion (Type Ⅲ and Ⅳ: 1 case each). Total knee replacement was conducted 2~3 years after the procedure in 3 cases (Type Ⅲ: 2 cases; Type Ⅳ: 1 case). Of the remaining 65 cases, the Lysholm scores were elevated from 50?12 preoperatively to 85?8 postoperatively (t=3.521, P
