A native arthritic knee locked in full extension is a rare presentation to an orthopaedic clinic. Often, fixed deformity cases present with an element of fixed flexion due to either a mechanical or non-mechanical block, but a full extension deformity has not been reported in the literature. The treatment of these complex cases often involves consideration of the biopsychosocial impact of the deformity, and holistic patient care is warranted. This case report explores the symptoms, investigations, management, and postoperative recovery of a 60-year-old patient presenting with a rare fixed extension deformity. The condition had a significant impact on the patient's physical and psychological state, and its impact on quality of life should not be dismissed. Multiple imaging modalities and surgical options were considered prior to surgical management with total knee arthroplasty. The management of this condition was demonstrated to be suitably treated with total knee arthroplasty with good postoperative function and recovery. However, further larger study series are required to provide more robust evidence as to the optimal management strategy.
一个处于完全伸直位锁定的原发性关节炎膝关节是骨科门诊罕见的病例表现。通常，固定畸形病例会因机械性或非机械性阻滞而存在一定程度的固定屈曲，但文献中尚未报道过完全伸直畸形的情况。这些复杂病例的治疗通常需要考虑畸形对生物心理社会的影响，全面的患者护理是必要的。本病例报告探讨了一名60岁患者出现罕见的固定伸直畸形的症状、检查、治疗及术后恢复情况。该病症对患者的身体和心理状态产生了重大影响，其对生活质量的影响不容忽视。在采用全膝关节置换术进行手术治疗之前，考虑了多种影像学检查方法和手术方案。事实证明，采用全膝关节置换术对该病症进行治疗效果良好，术后功能和恢复情况佳。然而，需要进一步开展更大规模的研究系列，以提供关于最佳治疗策略的更有力证据。
