Patients with various knee problems may benefit by having an arthroscopic examination of the knee. In an arthroscopic exam, the doctor inserts a slender instrument with a tiny TV camera on the end into the joint. This allows the doctor to look inside the joint and assess the problem. The operation doesn't require any large cuts or incisions. Two or three small puncture holes are all that are needed. Even so, patients tend to have quite a bit of discomfort afterward. The knee may swell and feel hot from inflammation. This can cause limited knee motion. A new dressing called a pain wrap is being used to control pain after an arthroscopic exam. The pain wrap is placed around the knee and removed only to do exercises. The dressing is changed every other day. All dressings are removed after a week. In this study, the pain wrap decreased patients' pain. However, it didn't change how much pain medication patients took. The joint had less swelling and the skin temperature was cooler with the pai...
Do patients with knee pain from osteoarthritis (OA) increase the weight and load through the knee after taking pain relievers? This is the first study to try and find an answer to the question. Researchers at the University of Chicago say pain relief increases the load while walking, but not during stair climbing. They think other factors may be involved in stair climbing. Many patients with OA end up with increased wear and tear on the inside edge of the knee. Pain causes them to limp or shift the weight to the other leg. Their walking speed slows down, and their rhythm becomes uneven. In this study, authors compared two groups: adults with OA, and adults without OA. The study was done in a motion analysis lab. Each group walked on a walkway that can measure force from the ground up through the knee. Speed and stride length were also measured. Three trials of walking and stair climbing were done. Then the OA group got a knee injection for pain. All patients reported pain relief. After 1...
