Knee: Minimally Invasive Total Knee Arthroplasty Compared with Traditional Total Knee Arthroplasty
Featuring Seth S. Leopold, M.D.

Dr. Seth Leopold demonstrates an educational minimally-invasive quadriceps-sparing total knee arthroplasty surgery. He compared his first 100 minimally invasive total knee arthroplasties with fifty procedures performed through a medial parapatellar approach, with respect to operative times, implant alignment, and clinical outcome. Clinical outcome data in this series tended to support the claims of proponents of minimally invasive total knee arthroplasty suggesting accelerated recovery, but they also echoed the concerns of one skeptical report that clinical results tend to converge with those after use of a traditional approach once outside the early postoperative period. Dr. Leopold also notes the minimally invasive total knee arthroplasty learning curve in this series was approximately fifty procedures. Dr. Leopold concludes that 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.
