过度活动是公认的膝盖骨不稳定的危险因素。在这项病例对照研究中，研究了高活动度对内侧髌股韧带(MPFL)重建治疗髌骨不稳定的临床结果的影响。对25名符合Beighton标准的高活动度患者进行了评估，并与50名年龄、性别、手术适应症和滑车发育不良程度匹配的对照组进行了比较。活动度高的患者的Beighton评分为6分，对照组的评分为4分。所有患者均采用自体半腱肌移植和标准化的关节镜控制技术进行MPFL重建。患者平均年龄25岁(17~49岁)，平均随访15个月(6~30个月)，多动症患者术后功能有明显改善，满意率、感觉改善、重复治疗意愿和推荐可能性均较高。功能改善显著低于对照组(P<；0.01)。关节过度活动不是MPFL重建的禁忌症，尽管建议在考虑手术前谨慎管理过度活动患者的期望。
Hypermobility is an acknowledged risk factor for patellar instability. In this case control study the influence of hypermobility on clinical outcome following medial patellofemoral ligament (MPFL) reconstruction for patellar instability was studied.A total of 25 patients with hypermobility as determined by the Beighton criteria were assessed and compared with a control group of 50 patients who were matched for age, gender, indication for surgery and degree of trochlear dysplasia. The patients with hypermobility had a Beighton Score of >= 6; the control patients had a score of < 4. All patients underwent MPFL reconstruction performed using semitendinosus autograft and a standardised arthroscopically controlled technique. The mean age of the patients was 25 years (17 to 49) and the mean follow-up was 15 months (6 to 30).Patients with hypermobility had a significant improvement in function following surgery, with reasonable rates of satisfaction, perceived improvement, willingness to repeat and likelihood of recommendation. Functional improvements were significantly less than in control patients (p < 0.01).Joint hypermobility is not a contraindication to MPFL reconstruction although caution is recommended in managing the expectations of patients with hypermobility before consideration of surgery.
