The shoulder is the most mobile joint in the body which also makes it more vulnerable to instability. Shoulder instability occurs when the upper arm bone slips partially or completely out of the socket. Once a shoulder dislocates, it becomes more prone to repeated episodes, known as chronic shoulder instability.

Over time, repeated dislocations can lead to pain, weakness, and loss of confidence in shoulder movement.

Struggling with shoulder instability? Dr. Samuel Koo offers expert treatment in Seattle to restore strength and stability. Schedule your consultation today!

Frozen shoulder also known as adhesive capsulitis is a condition that causes pain and significant loss of shoulder motion. It occurs when the joint capsule becomes inflamed and stiff, limiting how far and comfortably the shoulder can move.

While the exact cause is often unknown, frozen shoulder is more common in women and may be associated with conditions such as diabetes or thyroid disease. Early evaluation can help guide treatment and ease symptoms.

Osteoarthritis is a natural part of aging and develops gradually as joints wear down over time. As cartilage begins to fray and thin, joints may experience painful bone-on-bone contact that can limit movement and affect daily life.

While aging is the primary cause, factors such as prior joint injuries, family history, and excess weight can increase the risk of developing osteoarthritis.

If joint pain or stiffness is slowing you down, expert care can make a difference.
