Study Summary

Crepitus causing unsatisfied result to patients after posterior stabilized total knee arthroplasty. Recent retrospective study demonstrated removal of hyperplastic synovium in distal quadriceps caused reduce of crepitus. However, this study has limitation of time gap exist between arms, different in observation time and bias caused by retrospective review. Thus aim of this study is that by randomized trial, verified hyperplastic synovium in distal quadriceps causing crepitus.

Target enrolled patients in this study are scheduled to perform both total knee arthroplasty. Experimental group is randomized side (right or left) of knee, and control group is other side of knee. Both arms decided by randomized number table. Crepitus measured after 3mo, 6mo, 1year after surgical treatment

Study Description

Surgical treatment of TKA with synovium removal in distal quadriceps tendon performed classifed as experimental arm and TKA wiout synovium removal classified as control arm. Before surgical treatment, radiologic and physiological evaluation performed to check too much variance shown in either arm. Radiologic parameter include Hip knee ankle angle, Femoral tibial angle, Level of joint line, Insall-Salvati ratio, Posterior tibial slope, Posterior femoral condylar offset, Patellar thickness, Patellar tilt, Patellar displacement. During surgical treatment patella resurfacing in either group excluded this study. Indication of patella resufacing is ICRS grade IV in lateral surface of patella. After surgical procedure done check grade of crepitus (0-no crepitation, 1-fine crepitation, 2-coarse crepitation) with WOMAC, Knee Society Score, Eq-5D (European quality of life -5 Dimensions), Forgotten joint score after 3month, 6month and 1year after surgical procedure.

Other collecting variance Age, Gender, BMI, Range of motion of knee, Fmoeral/Tibial component size, PE thickness
