To investigate the clinical effect of arthroscopic fixation of tibial avulsion fracture of posterior cruciate ligament with a knot-free anchor and Endobuton titanium plate.
From October 2019 to October 2020, 12 patients with tibial avulsion fracture of posterior cruciate ligament were treated with the arthroscopic knot-free anchor and Endobuton titanium plate, including 9 males and 3 females. The age ranged from 23 to 58 years old. The time from injury to operation ranged from 2 to 9 days. There were 2 cases of Meyers typeⅡand 10 cases of Meyers type Ⅲ. There were 2 cases of meniscus injury and 1 case of partial injury of medial collateral ligament. The fracture healing and knee range of motion were evaluated after operation, and the clinicalefficacy was evaluated by Lysholm function score.
All patients were followed up for 12 months. All patients healed within 6 months, and there were no complications such as incision infection, lower extremity deep venous thrombosis and internal fixation falling off. The knee flexion range of motion recovered from 50°-90° before operation to 115°-130° 6 months after operation, and no patient had straightening disorder. Lysholm functional score recovered from preoperative 29-54 scores to 86-100 scores 12 months after operation.
Arthroscopic reduction and fixation of tibial avulsion fracture of posterior cruciate ligament with the knot-free anchor and Endobuton titanium plate has less complications, high fracture healing rate, good extension and flexion angle and early function recovery of knee joint.
探讨关节镜下使用免打结锚钉和Endobuton钛板固定后交叉韧带胫骨撕脱骨折的临床疗效。
2019年10月至2020年10月，对12例后交叉韧带胫骨撕脱骨折患者采用关节镜下免打结锚钉和Endobuton钛板治疗，其中男9例，女3例。年龄23～58岁。受伤至手术时间为2～9天。MeyersⅡ型2例，MeyersⅢ型10例。合并半月板损伤2例，内侧副韧带部分损伤1例。术后评估骨折愈合情况及膝关节活动度，采用Lysholm功能评分评估临床疗效。
所有患者均随访12个月。所有患者均在6个月内愈合，未出现切口感染、下肢深静脉血栓形成及内固定物脱落等并发症。膝关节屈曲活动度由术前的50°～90°恢复至术后6个月的115°～130°，无患者出现伸直障碍。Lysholm功能评分由术前的29～54分恢复至术后12个月的86～100分。
关节镜下使用免打结锚钉和Endobuton钛板复位固定后交叉韧带胫骨撕脱骨折并发症少，骨折愈合率高，屈伸角度良好，膝关节功能恢复早。
