Common signs include hearing or feeling a "pop" at the time of injury and experiencing instability or a buckling sensation in the knee.

An ACL injury usually occurs when the knee is sharply twisted or extended beyond its normal range of motion.

Frozen shoulder, also called adhesive capsulitis, is a thickening and tightening of the soft tissue capsule that surrounds the glenohumeral joint, the ball and socket joint of the shoulder.

The major symptoms of frozen shoulder are pain and loss of motion.

The labrum is a disk of cartilage on the glenoid, or “socket” side of the shoulder joint. It helps stabilize the joint and acts as a “bumper” to limit excessive motion of the humerus, the “ball” side of the shoulder joint.

The primary symptom of a labral tear that is not associated with instability is pain in the area of the injury. Labral tears that involve the biceps tendon can make using the biceps tendon painful. Patients with labral tears from internal impingement will complain that they have pain with throwing.

Repeated abrasion on any of the surfaces of the patella and femur stresses the soft tissues of the patellofemoral joint and may even lead to a bone bruise. In some cases, the pain is caused by a weakening of the articular cartilage and/or swelling within the joint.
