A knee replacement can’t be exactly like a normal person. However, basic function can usually be restored.
All surgeries are invasive. Knee replacement surgery is also traumatic, and the joint used for replacement is a prosthesis, even if the material of the prosthesis is better and the operation process is smooth, it can’t be completely the same as a normal person after the operation, but compared to the original diseased joint, the mobility of the joint after the replacement will be significantly improved, and it can be basically the same as a normal person in terms of standing up and walking.
If the replacement prosthesis is an ordinary non-high-flexing prosthesis, it may lead to limited joint movement after the operation, and it is difficult to reach the level of deep squatting. When a high-flexing prosthesis is chosen, the knee function can be restored to the maximum extent after active treatment and rehabilitation exercises.
After knee replacement surgery, you should pay attention to rest, avoid long time standing, walking, do not do strenuous exercise, reduce mountaineering, climbing and other activities, in order to reduce the wear and tear on the joint prosthesis, prolong the service life of the joint prosthesis.
