“It’s a common injury, especially in sports like baseball or tennis, or in jobs like painting or cleaning windows. It usually happens over time from normal wear and tear, or if you repeat the same arm motion over and over. But it also can happen suddenly if you fall on your arm or lift something heavy.
Types of rotator cuff surgery:
Arthroscopic. Your doctor will make a small cut in your shoulder then use an arthroscope — a tube with a small camera and tiny instruments — to fix the tear. This means your recovery time will likely be shorter than it would with another type of surgery.
Open. Your doctor uses larger instruments to go into the muscles of your shoulder and fix the tear.
Mini-Open. This uses both arthroscopic and open methods. Your doctor starts with the arthroscope and finishes with larger instruments.
Tendon transfer. If your tendon is too torn to reattach, the doctors can use another nearby tendon.
Shoulder replacement. If the rotator cuff tear is large enough, you may need to have your shoulder joint replaced.”
