Abstract Objective To analyze and compare the clinical effect of total knee arthroplasty(TKA) for patients with knee stiffness.Methods Nineteen patients (23 knees) were retrospectively analyzed after total knee arthroplasty from May 2012 to April 2017,including 7 males and 12 females.The age ranges from 48 to 79,with an average age of (63.63±7.75).The follow-up results were divided into three groups before operation,six months after operation and two years after operation and compared with each other.Clinical evaluation was performed using American Knee Society Knee(AKS) Score and range of motion(ROM).Results All 19 patients were followed up,and AKS and ROM were followed up for 6 months and 2 years after TKA.The range of motion increased from (31.17±9.63)°(range:10°to 47°)before surgery to (93.04±14.83)°(range:55° to 115°) six months after surgery,and (85.00±19.83)°(range:35° to 110°) two years after surgery.The difference between preoperative and postoperative activities was significant(P<0.05).The range of joint motion decreased from six months to two years after surgery (P<0.05).AKS scores were (33.17±12.32)(range:12 to 69)before surgery,(74.44±12.72)(range:53 to 99)six months after surgery,and (70.57±13.24)(range:52 to 96) two years after surgery.There were significant differences between preoperative and postoperative scores (P<0.05),and the AKS scores were significantly improved after the operation compared with that before the operation,but there was no significant difference between six months after the operation and two years after the operation (P>0.05).Conclusion Total knee replacement can significantly improve the motor function and quality of life of patients with knee stiffness.
