Osteochondral injury of the medial femoral condyle, in general, can be carried out in the same room, but need to be decided according to the specific situation of the patient. 1. General situation: the medial femoral condyle is located in the expansion of the lower end of the femur, cartilage injury that is the cartilage tissue of the medial femoral condyle. If it is only superficial cartilage damage, most patients take conservative treatment, need to rest and recuperate, at the same time can be combined with medication, support aids and so on. In this case, you can generally cohabit, but the amplitude of movement is not too large, try to keep the affected limb relatively stable state. 2. Special circumstances: if the injury is more serious, the medial femoral condyle cartilage injury, generally do not recommend coitus. Because the femur is a load-bearing bone, after activity due to gravity conduction, may lead to further aggravation of the injury, or even joint narrowing and other dysfunctions. And it is also an important reason because the recovery ability is poor after the total cartilage injury, which is often irreversible.
