What are the results of less invasive joint replacements?
Currently there are no long-term studies of minimally invasive joint replacements as the techniques and instruments used to perform these surgeries have been evolving over the last ten years. The orthopaedic literature shows that patients who undergo a less invasive joint replacement enjoy a faster recovery in the first 2-4 weeks after surgery. Studies have documented less blood loss at the time of surgery, less pain and pain medication usage, shorter hospital stays, faster return to walking with a cane or no assist device, and faster return to work. These early advantages are only significant in the first 6-12 weeks after surgery. By 3 months, joint replacement patients have achieved 90% of their ultimate recovery regardless of the approach used at the time of surgery. Long term success of a hip or knee replacement depends on the appropriate selection, sizing, and alignment of the implants.
With appropriate instruments and surgical training, this can be achieved through a minimally invasive or traditional approach to the procedure. Current studies of long-term results of hip and knee replacement suggest a 90-95% survivorship of the reconstructed joint at 20 years follow-up.
