Posterior Stabilized (PS) implants were used in 34 knees, rotating hinged knee implants were used in 2 knees. The procedures were carried out by a single surgeon protecting the deep layer of the medial collateral ligament. The patients\u2019 average age at the time of the operation was 67.6 \u00b1 12 years, and the average follow-up period was 9.0 \u00b1 3 years (range, 4-15 years). The Japanese Orthopaedic Association (JOA) knee score, range of motion (ROM) (extension\/flexion; measured in degrees), FTA (measured in degrees) and complications were investigated.\n\nResults: The Japanese Orthopaedic Association knee score significantly improved from an average of 51 \u00b1 12 points before the operation to 86 \u00b1 9 points after the operation (P &lt;0.001). The extension ROM and flexion ROM improved from, -13 \u00b1 13\u00b0 to a postoperative average of -2 \u00b1 4\u00b0, and 115 \u00b1 25\u00b0 to a postoperative average of 125 \u00b1 18\u00b0 respectively (P &lt;0.001). The standing FTA significantly improved from 158 \u00b1 9\u00b0 to an average of 173 \u00b1 2\u00b0 after the operation (P &lt;0.001). Thirty-four knees with severe valgus deformity were operated on using pos- terior stabilised implants, while only two knees required constrained implants. During follow-up, no complications, such as tibiofemoral instability, recurrence of valgus deformity, patellar necrosis, deep infection, wound problems, or peroneal nerve paralysis were observed.\n\nConclusion: This study has shown us that after performing TKA while preserving the d-MCL for valgus knee deformity good clinical results were obtained and no complications were observed.\n\nLevel of Evidence: Level IV, Therapeutic Study\n\nCite this article as: Ohno H, Murata M, Kamo T, Sugimoto H, Saito T.
