A 31-year-old woman with known Larsen syndrome presented with congenital chronic luxation of her right knee with increasing instability symptoms, which limited her daily activities. We refrained from a constrained knee arthroplasty due to her relatively young age and decided to perform a knee arthrodesis. Knee arthrodesis is a viable lifelong-lasting operative treatment alternative for specific instability-related knee disease. The knee arthrodesis was performed by double plating with an additional fixation of the patella. At 1-yearfollow-up, she was able to walk without limitations and did not experience any pain with complete consolidation of the arthrodesis. At 2-year follow-up, she performed all her daily activities without limitations. Both the Knee injury and Osteoarthritis Outcome Score (KOOS) and the International Knee Documentation Committee subjective knee form (IKDC) improved at 2-year follow-up (KOOS: 61.3; IKDC: 56.3) compared with 1-year follow-up (KOOS: 52; IKDC: 40.2).
一位 31 岁的女性患有已知的拉森综合征，她的右膝先天性慢性脱位，伴有逐渐加重的不稳定症状，这限制了她的日常活动。由于她年龄相对较小，我们避免了膝关节受限的关节置换术，并决定进行膝关节融合术。膝关节融合术是一种可行的、终身性的手术治疗选择，适用于特定的与不稳定相关的膝关节疾病。通过双钢板固定，并额外固定髌骨，完成了膝关节融合术。在 1 年的随访中，她能够无限制地行走，并且在融合完全固定后没有任何疼痛。在 2 年的随访中，她能够无限制地进行所有日常活动。与 1 年随访相比（KOOS：52；IKDC：40.2），2 年随访时膝关节损伤和骨关节炎结果评分（KOOS）和国际膝关节文献委员会主观膝关节评分（IKDC）都有所改善（KOOS：61.3；IKDC：56.3）。
