Can your body's own platelets play a role in treating certain shoulder injuries?

Platelet-Rich Plasma, or PRP, uses a concentrated portion of the patient's own blood and may be considered for certain chronic tendon injuries and conditions.

Dr. Samuel Koo uses PRP selectively, including for some cases involving rotator cuff tendinitis, impingement, bursitis, and bicipital tendinitis.

Is PRP appropriate for your shoulder? Start with an evaluation.

When shoulder arthritis becomes severe, everyday movements like reaching into a cabinet, getting dressed, or sleeping comfortably can become difficult.

Many patients can manage symptoms with non-surgical treatments, including activity modification, medication, therapy, or injections. When these options no longer provide enough relief, shoulder replacement may be considered.

Dr. Samuel Koo specializes exclusively in shoulder care and can help determine which treatment options fit your condition and goals.

Fall cleanup can be a workout for your shoulders.

Raking leaves, trimming branches, lifting yard bags, and repeatedly reaching overhead can place added stress on the shoulder—especially when you try to get everything done in one afternoon.

Take breaks, switch tasks to avoid repetitive motion, use proper lifting technique, and pay attention if your shoulder starts hurting. Pain that persists after you've rested deserves a closer look.

Shoulder surgery doesn't always mean a large incision or an overnight hospital stay.

Arthroscopy allows certain shoulder conditions to be treated through small incisions using a tiny camera and specialized instruments. It may be used for conditions including rotator cuff tears, shoulder impingement, labral tears, and instability.

Football season is back, and so are the hard hits that can put shoulders to the test.

A direct blow or fall onto the shoulder can injure the AC joint, where the collarbone meets the shoulder blade. Symptoms may include pain at the top of the shoulder, tenderness, swelling, or discomfort when moving the arm across the body.

If shoulder pain sticks around after an injury, getting it evaluated can help determine the extent of the damage and the appropriate treatment.

When reaching overhead or behind your back becomes increasingly difficult, frozen shoulder may be the reason.

Frozen shoulder can progress through several stages, with pain and stiffness sometimes lasting months or even years. Treatment may include anti-inflammatory medications, physical therapy, targeted stretching, cortisone injections, or an arthroscopic procedure when conservative treatment isn't enough.

If persistent stiffness is limiting what you can do, consider having your shoulder evaluated.
