Online published on 7 July, 2015. Abstract Background & Objectives Anterior knee pain is one of the common complication after Total Knee Arthroplasty (TKA). This study is an attempt to reduce or eliminate the problem of post -operative anterior knee pain by proper mechanical balancing of the patello–femoral joint during TKA. Methods 32 Patients with osteoarthritis or rheumatoid arthritis of knee requiring TKA were enrolled for this prospective study. We have excluded patients of revision knee arthroplasty, charcot joints and patients with life expectancy less than 10 years. Bilateral total knee arthroplasty was performed in 10 patients hence 42 total knee arthroplasties were studied. Along with meticulous attention to all aspects of TKA our study focuses on restoration of patellar height of 10 – 30 mm proximal to the prosthetic joint line, change in joint line of prosthesis as compared to original joint line from tibial tuberosity of less than 8mm and Judicious retinacular release, if needed. Results and Interpretation Post – operative excellent results were seen in 91% of cases. Good results were seen in 3% of cases, fair results were seen in 3% of cases and poor result in 3% of cases. No patient complained of anterior knee pain. Achieving proper mechanical balance of the patella-femoral joint is an excellent technique in an attempt to reduce post – operative incidence of anterior knee pain after TKA.
