Dr. Murphy Offers Minimally Invasive Knee Surgery


Every patient who is a candidate for knee replacement surgery is a candidate for minimally invasive knee replacement surgery. The orthopaedic surgery specialty of Joshua Murphy, M.D. is a less aggressive approach to knee replacement surgery. The technique is gentler on the soft tissue muscle, tendons, and ligaments surrounding the knee allowing less pain post-surgery. Less pain after surgery leads to a faster return to normal mobility for patients.


Key Differences

During conventional knee replacement surgery, the knee is in a position of hyperflexion with retractors pulling the kneecap. Tendons, ligaments and quadriceps muscle surrounding the knee are all stretched; effectively dislocating the knee. For Dr. Murphy, however, the knee is in a straight position during most of his surgeries, leaving those tissues relaxed and allowing for a smaller incision.



A smaller incision, less stress on the tissue, less pain, less pain medication allows patients a much faster return to mobility. “The real benefit comes from less pulling on the quad tendon, kneecap, patella tendon, ligaments and quadriceps muscle,” said Dr. Murphy.

The first 4-8 weeks following joint replacement surgery is where Dr. Murphy sees the difference, with many of his patients doing things like hiking in the Appalachian Mountains, playing multiple rounds of golf, and scuba diving just five weeks after surgery. Dr. Murphy spent a year in “very technically challenging” training, practicing and perfecting minimally invasive procedures. “The results are great,” Dr. Murphy said.
