title: Factors affecting the learning curve in Computer Assisted Total Knee Arthroplasty.
abstract: Mathematical modeling of learning curves have been used in industry since 1936. The advent of Computer Assisted Total Knee Arthroplasty allows the collection of hard data. We present our finding of a statistically significant mathematical model relating operative time, body mass index, experience of the surgeon and preoperative varus deformity in a prospective study of 241 computer assisted total knee arthroplasties. To the best of our knowledge, such a model has not been described before.
