BACKGROUND:Studies have shown that arthroscopic al-inside technology for meniscus repair has achieved good outcomes, and arthroscopic suture combined with sodium hyaluronate has an important role in the cartilage repair. OBJECTIVE:To observe the therapeutic effect of arthroscopic al-inside suture repair combined with sodium hyaluronate injection in the repair of discoid meniscus tears. METHODS:Twenty-two patients with discoid meniscus injury were subjected to arthroscopic al-inside suture repair combined with sodium hyaluronate injection. Al cases were confirmed to have attached edge relaxation or longitudinal crack in operation. After repair, effective rehabilitation training was done. RESULTS AND CONCLUSION:The operations for the 22 cases were al successful and there was no complication. Al patients were fol owed up for over 18 months. According to Ikenchi’s method (Lysholm knee score criterion), 11 cases were rated excel ent, 8 were rated good, and 3 were rated fair, with an excel ent/good rate of 86.36%. It is demonstrated that the al-inside suture repair under the guide of arthroscopy in discoid meniscus cases can remain the most appropriate anatomical structure of the meniscus that can play an effective function, and has the advantage of minimal invasion. Arthroscopic al-inside suture repair combined with intra-articular injection of sodium hyaluronate and standard rehabilitation training result in a lower complication rate and effectively promotes the meniscus repair.%背景：研究表明，关节镜下缝合成形治疗膝关节半月板损伤临床效果满意，而结合玻璃酸钠对促进软骨修复有重要作用。目的：分析关节镜下缝合成形结合玻璃酸钠注射促进膝关节盘状半月板损伤的软骨修复。 方法：关节镜下缝合成形结合玻璃酸钠注射修复盘状半月板损伤22例，术中证实均为附着缘松弛或纵裂。采用关节镜下缝合成形术结合玻璃酸钠注射治疗，继而进行有效的康复计划。 结果与结论：22例患者治疗全部成功，无并发症。患者均获得18个月以上随访，术后疗效根据Ikenchi评分方法：优11例，良8例，可3例，优良率86%。膝关节镜下盘状半月板缝合成形可以最大程度地保留半月板解剖结构，使其发挥有效功能且损伤小，关节修复后配和关节腔注射玻璃酸钠及正规的康复训练并发症少，可有效促进半月板关节软骨修复。
