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.
