Shoulder instability can significantly impact daily life—especially when the joint repeatedly slips out of place or feels unreliable during movement. Because the shoulder is the most mobile joint in the body, it is also the most prone to dislocation and chronic instability.

In many cases, instability develops after a traumatic injury that damages the labrum or stretches the surrounding ligaments. Over time, this can lead to repeated dislocations and ongoing discomfort.

At our Seattle-area practice, treatment begins with a thorough evaluation and often includes physical therapy to strengthen the shoulder and restore stability. For patients who do not improve with conservative care, minimally invasive arthroscopic stabilization may be recommended to repair damaged structures and prevent future dislocations.

If you are experiencing recurring shoulder instability, early evaluation is key to protecting long-term joint health.

Platelet-Rich Plasma (PRP) therapy is an advanced, non-surgical treatment option used to support healing in injured tendons, ligaments, and muscles. This therapy uses a concentrated sample of your own blood, rich in platelets and growth factors, to help stimulate the body’s natural repair process. 💪

In the shoulder, PRP is often used to treat conditions such as rotator cuff irritation, tendonitis, bursitis, and chronic overuse injuries. These growth factors may help improve collagen production and tissue strength over time, supporting recovery in damaged structures.

For patients in Kirkland, WA and the greater Seattle area, PRP can be an important part of a comprehensive shoulder care plan designed to reduce pain and improve function.

If you're experiencing shoulder pain, PRP injections may help to prevent surgery. To discuss your options with an expert in Seattle, contact Dr. Koo today!

💪 Shoulder arthroscopy is a minimally invasive procedure often used to treat conditions like rotator cuff injuries and shoulder instability. Because it requires only small incisions, recovery begins quickly and most patients are able to go home the same day.

After surgery, you will spend a short time in the recovery area where the care team monitors your comfort and response to anesthesia. Once you are stable, you will be discharged with detailed instructions for home care.

It is important to arrange for a responsible adult to drive you home, as you will not be able to drive after the procedure. Following these early steps helps set the foundation for a smooth recovery.
