Minimally Invasive Partial Knee Replacement Surgery
Our Results in 140 surgeries
We have performed over 1200 minimally invasive total and partial knee replacements. Our results of the first 140 MIS total knee replacements and MIS partial knee replacements were analyzed and compared to 100 total knee replacements done with traditional, full-sized incisions. These results have been published in multiple journals* and have documented improved early rehabilitation, range of motion, and function when MIS techniques are used.
MIS total knee replacements performed better than knee replacement done with standard techniques:
- Better Range of Motion
- Less postoperative Pain
- Shorter Rehabilitation Time
- Shorter Incision
- Fewer Complications
- Less Time in Hospital
- Less Blood Loss
- Earlier Return to Activities
Partial Knee Replacement Versus Total Knee Replacement
We have also published our results of partial knee replacements compared to total knee replacements. In partial knee replacements, the range of motion was significantly better throughout the first year. The overall function and patient satisfaction was slightly better for patients with partial knee replacements compared to those with total knee replacements. Our results show that early rehabilitation was more complete and easier for partial knees than it was for MIS total knee replacement.
Patient expectations for functional outcome and conditions of satisfaction are not always met after traditional total knee replacement. Many authors have reported that many patients who received total knee replacements with standard incisions reported limitation in functional activities. These limitations included even basic activities such as kneeling, squatting, lateral movement, carrying routine loads, dancing, gardening, and sexual activity.
Many patients want to return to work, get up from low chairs, garden, squat down to check their putts, climb out of sand traps, and ascend and descend into sand traps, boats, sports stadiums, and other more precarious environs. They require improved overall performance, better range of motion, strength, early rehabilitation, longevity, and stability. Furthermore, the increased potential for revision surgery in these patients demand solutions that are bone-preserving.
Traditional total knee replacement is an effective, well documented, and widely accepted surgical solution for patients with severe arthritis. However, patient dissatisfaction related to postoperative pain, stiffness, and long difficult rehabilitation persist, even with modern implant design.
Minimally invasive surgical techniques for total knee replacement and partial knee replacement help patients with their postoperative rehabilitation. MIS partial knee replacement offers improvements in bone preservation and early rehabilitation when compared to traditional total knee replacement. For the patient who is not appropriate for unicondylar knee replacement, MIS total knee replacement techniques can offer early rehabilitation comparable to unicondylar knee replacement.
