To observe the therapeutic effects of arthroscopic treatment for recurrent patellar dislocation by anatomical reconstruction of medial patellarfemoral ligament.
From June 2009 to December 2014, 25 patients with recurrent patellar dislocation were treated with anatomical reconstruction of medial patellarfemoral ligament surgery under arthroscopy. There were 10 males and 15 females, with an average age of 18.4 years old (ranged, 15 to 25 years old ). There were 15 patients who had a medical history of sports injury, 7 patients had a chronic impairment history, and the other 3 patients had the symptoms without obvious predisposing causes. Fourteen patients had injuries on the right knee and 11 patients had injuries on the left knee. All the patients suffered from patellar dislocation 3 to 10 times. After operation, the exercise of knee joint were performed postoperatively. The knee range of motion, Lysholm score, Kujala score, Insall criteria, Patellar apprehension test and patellar grinding test were observed to evaluate the clinical effects.
All the patients were followed up, and the duration ranged from 12 to 48 months, with an average of 24.8 months. After surgery, all the wounds were healed excellent and there were no complications like surgical incision infection or patellar redislocation. The ranges of motion was increased from preoperative (105.40±5.93)° to postoperative(122.60±5.42)°. At the latest follow-up, the Lysholm scores were increased from preoperative 64.12±7.49 to postoperative 91.44±5.53, the Kujala scores were increased from preoperative 57.88±5.10 to postoperative 92.44±2.69. According to the Insall criteria, 19 patients got an excellent result, 5 good and 1 fair.
It has a satisfactory clinical therapeutic effect on anatomical reconstruction of medial patellarfemoral ligament under arthroscopy for the treatment of recurrent patellar dislocation. It is helpful for the relief of clinical symptoms and improvement of knee joint function.
观察关节镜下内侧髌股韧带解剖重建治疗复发性髌骨脱位的疗效。
2009年6月至2014年12月，对25例复发性髌骨脱位患者行关节镜下内侧髌股韧带解剖重建术。其中男性10例，女性15例，平均年龄18.4岁（15～25岁）。有运动损伤史15例，慢性损伤史7例，无明显诱因3例。右膝损伤14例，左膝损伤11例。所有患者髌骨脱位3～10次。术后进行膝关节功能锻炼，观察膝关节活动范围、Lysholm评分、Kujala评分、Insall标准、髌骨恐惧试验及髌骨研磨试验，评估临床疗效。
所有患者均获随访，随访时间12～48个月，平均24.8个月。术后所有切口愈合良好，无手术切口感染、髌骨再脱位等并发症。膝关节活动范围由术前（105.40±5.93）°增加至术后（122.60±5.42）°。末次随访时，Lysholm评分由术前64.12±7.49提高至术后91.44±5.53，Kujala评分由术前57.88±5.10提高至术后92.44±2.69。按Insall标准评定，优19例，良5例，可1例。
关节镜下内侧髌股韧带解剖重建治疗复发性髌骨脱位临床疗效满意，有助于缓解临床症状，改善膝关节功能。
