Comparison of Multiradius and Singleradius Prosthesis Design in Total Knee Arthroplasty Using With Association Sagittal Patellar Offset and Anterior Knee Pain

The Investigators would like to compare multiradius and single-radius total knee arthroplasty using with association between sagittal patellar offset and anterior knee pain in subjects having undergone bilateral total knee replacement.

Study Overview

Detailed Description

A prospective, interventional study. A total of to 494 subjects requiring bilateral multiradius( n=247) and singlerasius(n=247) knee arthroplasty will be enrolled. Anterior femoral offset, femoral diameter and patellar offset will be measured by orthopaedic surgeons. In addition, Visual Analogue Scale Score, Oxford Knee Score, WOMAC, SF12 and SF36 will be evaluated postoperative in patients long-term follow up to see if there is a relationship between anterior femoral offset and anterior knee pain. In the direct lateral knee joint radiograph, the distance between the two parallel axis extending from both cortices of the femur is measured as "femoral diameter".The remaining length between the anterior axis and the maximum peak at the anterior of the prosthesis is considered as an "anterior femoral offset". Sagittal patellar offset is accepted by us as the ratio of the anterior femoral offset to the remaining distance between the maximum anterior point of the patella and the posterior vertex in the direct lateral knee joint radiography.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Quadruple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: singleradius
Single Radius(SR) femoral design will be perfomed to patients who is going to total knee arthroplasty. Single Radius femoral design is one of knee prosthesis' pattern which shows variation in knee kinematics
singleradius and multiradius total knee arthroplasty
Experimental: Multiradius
Multi Radius(MR) femoral design will be perfomed to patients who is going to total knee arthroplasty. Multi Radius femoral design is one of knee prosthesis' pattern which shows variation in knee kinematics
