UNASSIGNED: A 47-year-old male presented with chronic patellar tendon tears with HO, resulting in an inability to extend the right knee fully. Krackow suture repair augmented by autograft semitendinosus and gracilis was employed after debriding intra-substance patella tendon HO and fibrotic tissue. The repair was augmented using a method described by Chen et al. Postoperative recovery was uneventful, and the patient demonstrated an excellent Knee Society Score (86/100) at 6 months of follow-up. Proximal migration of the patella, poor tissue quality, scar tissue formation, and quadriceps atrophy pose unique challenges in managing chronic patellar tendon tears.
UNASSIGNED: HO increased the probability of patella baja after the reconstruction. To alleviate that, precise pre-op planning, careful method selection, and proper execution of the selected method are very important. A comprehensive review of 14 different methodologies for managing chronic patellar tendon tears, comprising eight case series and six case reports, was conducted. The selection of an appropriate technique should be based on individual patient characteristics, resource availability, and the surgeon\'s expertise.
■一名47岁的男性出现慢性髌腱撕裂伴HO,导致右膝不能完全伸展。在清创髌骨内肌腱HO和纤维化组织后,采用了自体移植半腱肌和股薄肌增强的Krackow缝合修复。使用Chen等人描述的方法增强修复。术后恢复顺利,患者在随访6个月时表现出优异的膝关节社会评分(86/100)。髌骨近端迁移,组织质量差,瘢痕组织形成,股四头肌萎缩在治疗慢性髌腱撕裂方面带来了独特的挑战。
■HO增加了重建后髌骨的概率。为了缓解这种情况,精确的术前计划,仔细的方法选择,正确执行所选方法非常重要。全面回顾了14种不同的治疗慢性髌腱撕裂的方法,包括八个病例系列和六个病例报告,进行了。选择合适的技术应根据患者的个体特征,资源可用性,和外科医生的专业知识。
