To discuss the method and effect of total knee arthroplasty osteotomy and soft tissue release for serious knee joint space narrowing. Clinical data of 80 patients from October 2013 to December 2014 was selected with a retrospective method. All patients have undergone total knee arthroplasty. Then the X-rays plain film in weight loading was measured before and after operation and osteotomy was performed accurately according to the knee joint scores and the conditions of lower limb alignments. The average angle of tibial plateau osteotomy of postoperative patients was 4.3°, and the corrective angle of soft tissue balancing was 10.7°; the postoperative patients’ indicies including range of joint motion, knee joint HSS score, angle between articular surfaces, tibial angle, femoral-tibial angle and flexion contracture were distinctly better than the preoperative indicies (p<0.05) and the differences were statistically significant; the postoperative patients’ flexion contracture and range of joint motion were distinctly better than the preoperative indicies (p<0.05) and the differences were statistically significant. The effective release of the soft tissue of the posterior joint capsule under direct vision can avoid excess osteotomy and get satisfactory knee replacement space without influencing the patients’ joint recovery.
