Jennifer Mathews: Last summer, a severe case of arthritis in his knee made it impossible for Ed Schultz to put on his shoes. A scan of his knee confirmed the problem. Ed Schultz: There was no cartilage at all, no cushioning of any kind between the bones, and so when I'd walk, it was a mortar and pestle grinding away at each other. Jennifer Mathews: Until recently, fixing the problem would have meant total knee replacement. Because only part of Ed's knee was affected, Doctor Michael Bronson recommended a far less invasive option, a partial knee replacement. Dr. Michael Bronson: In a unicompartmental replacement, what we're doing is just resurfacing that area which is worn out. Jennifer Mathews: A metal runner and small plastic disc replace the worn cartlidge, providing a new cushion between the bones. The 45-minute procedure requires a much smaller incision than a total knee replacement, has less blood loss, and a faster recovery. Dr. Michael Bronson: Whereas in total knee replacement, we talk about recovery being 3 to 6 months, in these operations, we're talking about weeks. Jennifer Mathews: Even more encouraging is that the improvement lasts. Michael Bronson: And the data that are just coming back after 10 years, shows that 95 percent of patients are still functioning as they did in the beginning, which is an excellent long-term prognosis. Ed Schultz: I really have, I believe, virtually full mobility with the knee. Jennifer Mathews: If he's like the others, it will continue. This Jennifer Mathews reporting.
