Minimally invasive total knee arthroplasty compared with traditional total knee arthroplasty. Assessment of the learning curve and the postoperative recuperative period.
There is disagreement about whether so-called minimally invasive approaches result in faster recovery following total knee arthroplasty. It is also unknown whether patients are exposed to excess risk during the surgeon’s learning curve. We hypothesized that a minimally invasive quadriceps-sparing approach to total knee arthroplasty would allow earlier clinical recovery but would require longer operative times and compromise component alignment during the learning period compared with a traditional medial parapatellar approach…
…A quadriceps-sparing minimally invasive approach seems to facilitate recovery, but a substantial learning curve (fifty procedures in the hands of a high-volume arthroplasty surgeon) may be required. If this experience is typical, the learning curve may be unacceptably long for a low-volume arthroplasty surgeon.
