文题释义:
膝外翻:因各种病变导致膝关节股胫角(股骨和胫骨解剖力线的夹角)大于>10°的被称为膝外翻,>20°的为重度膝外翻。
软组织平衡:在全膝关节置换中,若膝关节的屈曲-伸直间隙内外侧一致,则可称为软组织平衡。
 
摘要
背景:软组织平衡对于膝关节置换后的稳定性至关重要,在处理膝外翻畸形的软组织平衡上往往比膝内翻更为复杂,国内外学者在膝外翻全膝关节置换中使用的软组织平衡方法并不统一。
目的:在膝外翻的全膝关节置换中,评价Wihteside与Ranawat软组织松解术相结合在软组织平衡中的应用效果。
方法:选择西南医科大学附属医院2011至2014年收治的膝外翻患者26例(30膝),全部采用经髌旁内侧入路、后稳定型假体、常规截骨以及Wihteside与Ranawat软组织松解术相结合的方法行全膝关节置换。比较患膝置换前与末次随访时的股胫角、膝关节活动度、美国特种外科医院评分以及美国膝关节协会评分,评价置换后疗效。
结果与结论:①26例患者(30膝)均获随访,随访时间为12-48个月,末次随访摄片显示所有患者均未出现假体松动及下沉情况;②与置换前相比,末次随访时美国特种外科医院评分、美国膝关节协会评分、股胫角和膝关节活动度均显著改善(P < 0.05);③提示采用经髌旁内侧入路、后稳定型假体以及结合Wihteside与 Ranawat软组织松解术的全膝关节置换治疗膝外翻畸形可以取得满意的早期效果。

Abstract:

BACKGROUND: Soft tissue balance is critical for the stability after total knee arthroplasty (TKA). Dealing with the soft tissue balance of valgus knee is usually more complex than the soft tissue balance of genu varus, and the methods of soft tissue balance in TKA of genu valgum has not yet been unified.

OBJECTIVE: To investigate the curative effect of Wihteside combined with Ranawat release in the soft tissue balance in the TKA of genu valgus.
METHODS: Twenty-six patients (30 knees) with knee valgus admitted at the Affiliated Hospital of Southwest Medical University from 2011 to 2014 were selected. All patients received the TKA with medial parapatellar approach, posterior stabilized prosthesis, conventional osteotomy, and Wihteside combined with Ranawat release. The femorotibial angle, range of motion of the knee joint, the Hospital for Special Surgery and Knee Society Score at baseline and last follow-up were compared to evaluate the curative efficacy.
RESULTS AND CONCLUSION: (1) Twenty-six patients (30 knees) all followed up for 12-48 months. At the last follow-up, no prosthesis loosening or subsidence was seen on the radiographic images. (2) Compared with the baseline, the Hospital for Special Surgery, Knee Society Score, femorotibial angle, and range of motion of the knee joint at last follow-up were significantly improved (P < 0.05). (3) These results imply that the TKA of genu valgus through medial parapatellar approach, using posterior stabilized prosthesis, conventional osteotomy, and Wihteside combined with Ranawat release can obtain satisfactory outcomes.
