Patella Retraction Versus Eversion in Total Knee Replacement

Purpose -Surgical exposure of the knee during total knee arthroplasty requires mobilization of the patella. In the current study an attempt has been made to compare two techniques of the patella mobilization used in knee arthroplasty. Mateial and methods-40 patients were divided into two groups, Group 1 include patients underwent TKR using medial para-patellar approach with patellar eversion and Group 2 include patients underwent TKR using medial Para-patellar. The outcome were measured using Hospital stay, operative time, quadriceps strength (Quadriceps Muscle Strength Score, QMSS), pain, Knee society score (KSS), Knee function score (KFS) and Patella height using Insall-Salvati score Results- both groups were compareable, we did not find any difference between two groups using above criterias. Conclusion-Both techniques give good results in TKA. Its surgeons personal choice but results may vary in obese patients
