简要总结
Osteoarthritis is a common degenerative joint disorder affecting the elderly population.The knee is the principal peripheral joint affected, resulting in progressive loss of function, pain and stiffness. Total knee arthroplasty (TKA) is a common and successful treatment for end-stage osteoarthritis. The main goals of TKA are aimed at relieving pain, improving the patient’s quality of life, and restoring function while optimizing implant longevity
Most popular total knee prosthesis used are cruciate retaining and posterior stabilized. These two different TKA designs are related to two main kinematic problems of knee. The first is paradoxical motion that is an anterior translation of femoral condyles during flexion instead of physiological rollback,the second is reverse screw home that is extra rotation of tibia about 15 degrees on femur during the last 20 degrees of extension and it may cause inferior range of motion and patello femoral instability.
Medial pivot variety of cruciate retaining implant mimics the natural knee kinematics and helps to overcome the above problems. Though outcomes following medial pivot TKA have been compared with TKA using posterior stabilized components in the past, there is scant literature comparing outcomes of TKA using medial pivot versus cruciate retaining prostheses. The aim of this study is to compare clinical and radiological outcomes in the patients following medial pivot cruciate retaining TKA and other cruciate retaining TKA
