The medial collateral ligament (MCL) on the inner side of the knee is most often torn when there is a force that strikes the outside of the knee. The MCL attempts to resist widening of the joint and tears if the force is too great. When this happens, you face a recovery time of weeks to months, depending on the grade of the MCL tear.
A dislocation of the kneecap occurs when the patella comes completely out of its groove on the end of the thigh bone (femur), and comes to rest on the outside of the knee joint. Kneecap dislocations usually occur as a significant injury the first time the injury occurs, but the kneecap may dislocate much more easily thereafter.
A recently published study outlines an alternative multimodal pain management pathway that eliminates the need for opioids in patients undergoing elective reverse and anatomic total shoulder arthroplasty.
Determining the cause of a swollen knee can sometimes be challenging. It may an acute condition caused by a traumatic injury or a chronic one which has developed slowly over time.
Hearing a cracking or popping in the shoulder can be unsettling. However, unless it accompanies pain, swelling, or other symptoms, joint cracking and popping are generally harmless.
