%X This study aimed to explore a new surgical technique for gap balance by tightening the medial collateral ligament (MCL) in total knee arthroplasty (TKA) in patients with fixed valgus deformity. A prospective analysis was performed on 15 patients (16 knees) with a fixed valgus deformity that was corrected by tightening the MCL during TKA. A single surgeon performed all the 16 TKAs using nonconstrained posterior substituting implant, with two knees treated with long-stem tibial prosthesis. Clinical scores, knee stability, and radiographic evaluations were recorded preoperatively and postoperatively. Complete weight-bearing could be carried out under the protection of the brace postoperatively. At the third month after surgery, X-rays showed the brace was not worn. The mean follow-up was 26.6 months (range 12¨C42 months). The average preoperative mechanical axis was 15.4 ¡À 2.3¡ã (range 11¨C25¡ã), and postoperatively it was 0.6 ¡À 0.1¡ã (range 0¨C2¡ã). No complication relative to the technique occurred. This new surgical technique has demonstrated excellent early clinical results and can be a good supplement for fixed valgus knee arthroplasty.
