Abstract : Mismatch between the components in Total Knee Arthroplasty (TKA) and the anatomical dimen-sions is always a hot topic for discussion. To study the same in our subset of patients, we con-ducted this study. Intra-operatively, the distal femoral dimensions were measured using sterile calipers after removing the osteophytes and compared with the medio-lateral dimensions (ML) of the implants used. We found that APM ( AP dimension of medial condyle ) and APL ( AP dimension of lateral condyle ) have positive correlation with ML. Male patients have bigger distal femoral dimensions and more mediolateral mismatch when compared to fe-males. None of the implants used had the perfect match with the anatomical dimension. The medio-lateral mismatch is more in bigger knees than in the smaller knees. Functional scoring was done till 1 year post operative period which did not reveal any statistically significant difference between those with larger and lesser ML mismatch.
