“During the 2008-2011 time frame, I had seen Dr. Nonweiler about recurring problems with my left knee. As a result of a series of surgeries since the age of 16, compounded by endurance/long distance cycling as a hobby, that knee was a constant source of problems. Following orthoscopic surgery and subsequent meniscus tear in 2009 during a recovery ride, Dr. Nonweiler suggested a partial knee resurfacing. MRI images showed asymmetric degeneration in the left knee, with the lateral side showing normal arthritic degeneration, whereas the medial compartment looked like the knee of a 70-year-old instead of a 49-year-old. Thus, total replacement was not indicated. In November 2011, I underwent surgery for implant of Stryker devices to resurface the medial surfaces of the left knee.

“I have been extremely pleased with the implants. There is no sugar coating the pain associated with recovering from such surgery, but following normal recovery, rehab, and PT, I returned to a normal lifestyle, including mountain and road biking. The rehab period was also somewhat shorter compared to a total knee replacement, due to the fact that lateral tissues and ligaments did not have to be impacted by the procedure. The breakthrough for me came in the summer of 2012, as I was wiring a travel trailer and realized that I was kneeling on a concrete driveway in shorts and not even realizing it. This would have been unheard of prior to the procedure. I continue to enjoy a robust outdoor Central Oregon lifestyle that includes hiking, cycling, hunting, snowshoeing, cross country skiing, and other activities.

“I became aware of some reports of dissatisfaction with partial knee surfaces from that time period. I want to emphasize that in my case, the knee feels completely normal, and in many ways, more stable and solid than my right knee, which is showing the signs of more symmetric degeneration at the age of 55. Motion is fluid and without any clicking or catching. Tactile and visual presentation is perfectly normal and comparable to my right knee. There is no noticeable impact due to external temperature or humidity. I have also noticed that it did not adversely impact air travel, as I had anticipated it setting off every metal detector I passed through. I have also had subsequent MRIs without incident or need for shield.

“I am also aware of the fact that surgical technology has continued to improve, and that nowadays orthopedic operating rooms have their own laser measurement and C&C milling machines on site, allowing for even greater precision in matching the implants to the patient’s bone surfaces. Given my experience and the ongoing advances in technology, I would not hesitate to recommend partial knee resurfacing to a patient whose history and symptoms warrant consideration of such a procedure.”
