The surgery reconstructs the torn elbow ligament using a tendon from another part of the body to restore strength and stability.
Japan’s baseball prowess is universally acclaimed. The advanced sports medicine supporting these top athletes is vital to their performance. Our center boasts team doctors from professional baseball teams, particularly renowned for their expertise in world-class UCL reconstruction surgery.
