You may have heard of the rotator cuff before, but do you know what it is? The rotator cuff is made of muscles and tendons that come together to cover the head of the humerus. These tendons attach the humerus to the shoulder blade and play a large part in your ability to lift and rotate your arm. Below are three common rotator cuff injuries.
The medial, or inside, and lateral, or outside, collateral ligaments help to protect the knee from unusual or side-to-side movements. They also serve to stabilize the knee. The patella ligament connects the bottom of the patella to the top of the tibia.
The knee joint is very important in helping us move. If a problem occurs with the knee, it can be very painful and make mobility difficult or impossible. One of the most common knee injuries is a torn meniscus. This injury can happen to anyone but often happens to athletes and older people.
The glenohumeral joint, or shoulder joint, is not as stable as the other joints in the body, so shoulder dislocation is fairly common. A shoulder dislocation occurs when the top of the bone in the upper arm, called the humerus, is forced out of the glenoid, the socket in the shoulder joint.
The cartilage that lines the bones within a joint is subject to constant wear and tear. As a result, articular cartilage can be worn off and patients can experience pain and reduced mobility. This warrants cartilage repair.
