Abstract:
OBJECTIVE: To investigate the short-term effectiveness of calcaneal lateral displacement osteotomy with lateral ligament repair in the treatment of Takakura stage Ⅱ varus-type ankle arthritis. METHODS: A retrospective analysis was performed on the clinical data of 13 patients with Takakura stage Ⅱ varus-type ankle arthritis treated with calcaneal lateral displacement osteotomy with lateral ligament repair between January 2016 and December 2020. There were 6 males and 7 females aged 31-65 years, with an average age of 53.6 years. The preoperative tibial-ankle surface angle (TASA) was (88.13±1.01)°, medial distal tibial angle (MDTA) was (86.36±1.49)°, tibial talar surface angle (TTSA) was (6.03±1.63)°, talar tilting angle (TTA) was (81.95±2.15)°, and tibiocalcaneal axis angle (TCAA) was (-5.74±6.81)°. The preoperative American Orthopedic Foot and Ankle Society (AOFAS) score was 56.3±7.1 and the pain visual analogue scale (VAS) score was 3.7±0.5. AOFAS scores, VAS scores, TTSA, TTA, and TCAA were compared between pre- and post-operatively. RESULTS: All 13 patients were followed up 14-41 months, with an average of 28.7 months. The osteotomies healed in all patients. The last follow-up revealed TTA, TTSA, and TCAA to be (88.27±1.19)°, (-0.13±1.37)°, and (2.09±5.10)° respectively, the AOFAS score was 84.3±4.2 and the VAS score was 0.7±0.5, all showing significant improvement when compared to preoperative values ( P<0.05). CONCLUSION: For patients with Takakura stage Ⅱ varus-type ankle arthritis, calcaneal lateral displacement osteotomy with lateral ligament repair can correct the lower limb force line, regain ankle stability, and achieving good short-term effectiveness. 目的: 探讨跟骨外移截骨并踝关节外侧韧带修复治疗Takakura Ⅱ期内翻型踝关节炎的早期疗效。. 方法: 回顾性分析2016年1月—2020年12月采用跟骨外移截骨并踝关节外侧韧带修复治疗的13例内翻型Takakura Ⅱ期踝关节炎患者临床资料。男6例，女7例；年龄31～65岁，平均53.6岁。术前胫骨远端关节面角（tibial-ankle surface angle，TASA）（88.13±1.01）°，胫骨远端内侧关节面角（medial distal tibial angle，MDTA）（86.36±1.49）°，胫距关节角（tibial talar surface angle，TTSA）（6.03±1.63）°，距骨倾斜角（talar tilting angle，TTA）（81.95±2.15）°，跟骨轴位片胫跟角（tibiocalcaneal axis angle，TCAA）（−5.74±6.81）°。术前美国矫形足踝协会（AOFAS）评分（56.3±7.1）分，疼痛视觉模拟评分（VAS）（3.7±0.5）分。比较手术前后AOFAS评分、VAS评分及TTSA、TTA、TCAA。. 结果: 13例患者均获随访，随访时间14～41个月，平均28.7个月。所有患者截骨均愈合。末次随访时TTA、TTSA、TCAA分别为（88.27±1.19）°、（−0.13±1.37）°、（2.09±5.10）°，AOFAS后足评分为（84.3±4.2）分，VAS评分为（0.7±0.5）分，均较术前显著改善，差异有统计学意义（ P<0.05）。. 结论: 对于Takakura Ⅱ期内翻型踝关节炎患者，跟骨外移截骨并踝关节外侧韧带修复可以纠正下肢力线，重获踝关节稳定性，取得较好的早期临床效果。.
