Minimally invasive surgical procedure used to diagnose and treat elbow joint problems. Small incisions and a tiny camera allow surgeons to remove bone spurs, loose fragments, or inflamed tissue. This approach reduces pain, speeds recovery, preserves joint function, and helps patients return to daily activities and sports more quickly.
Surgical procedure that replaces damaged parts of the shoulder with artificial components, relieving pain and restoring mobility. It is commonly recommended for severe arthritis, fractures, or rotator cuff injuries. Advanced techniques and implants allow patients to regain function, improve quality of life, and return to daily activities.
