应用PGLA膜治疗股骨骨折创伤后膝关节功能障碍临床研究

目的：评价PGLA（聚乙交酯丙交酯）膜应用于股四头肌成形术中治疗股骨骨折创伤后膝关节功能障碍（PKJD）的临床价值。方弦：对6例股骨骨折伴发PKJD患者采用直视下股四头肌成形术联合应用PGLA膜治疗，并评价其临床治疗效果。结果：所有患者随访1年，其中4例于术后12周时膝关节活动接近正常，1例6个月时活动接近正常，平均屈膝角度为109．7°，总优良率为83．33％。结论：股四头肌成形术联合应用PGLA膜方法治疗PKJD效果满意，可以解决传统手术必须早期功能锻炼增加患者治疗痛苦的缺点，但由于临床应用例数有限，应进一步观察其疗效。

Clinical evaluation of PGLA film for treatment of posttraumatic knee joint dysfunction caused by femoral fracture

Objective： To evaluate the clinical value of PGLA film for quadriceps angioplasty in the treatment of post-traumatic knee dysfunction （PKJD） caused by femoral fractures. Methods： Six cases of PKJD caused by femoral fractures were treated with quadriceps angioplasty combined to PGLA film, and the clinical effects were evaluated. Results： All patients were followed up 1 year, 4 cases and 1 case were recovered nearly normal in after 12 weeks and 6 months separately, and average flexion angle was close to 109.7°, the efficient was 83.33%. Conclusion： There are satisfied results on Quadriceps angioplasty combined with PGLA film in the treatment of PKJD, clue to the limited clinical application cases, clinical efficacy should be observed further.
