The human knee can bend up to 160 degrees. This much motion allows us to easily do activities like getting in and out of the bathtub. It also makes it possible to squat down to check the line for a putt on the green while playing golf. Others use this amount of flexion to kneel or to squat while gardening, praying, or doing work tasks. The knee rarely bends this far again after a knee joint replacement. The average patient has between 100 and 115 degrees of knee bend. Knee flexion after total knee replacement (TKR) rarely goes beyond 120 degrees. The reasons for this limit in motion are many and varied. Researchers report factors present before, during, and after the operation that can affect knee flexion. In this article, doctors from Harvard Medical School outline each of those factors and discuss them. The doctors say that to increase knee flexion, we must first know how the healthy human knee works. Then limiting factors can be changed to mimic the normal knee. Three TKR implants o...
Hi good day sir/mam, I've been experiencing this pain a while now. My jaw and head hurts but only On the left side. For instance if I bend down with my head facing downwards and raise back up it pains a lot for a minute or two then slightly easier to bear with.
