Surgery to repair a long head bicep tendon is generally safe with rare complications and should restore almost all of the patient's arm strength and function, states the Cleveland Clinic. Patients who have bicep tendon repair surgery should expect to do exercises to rehabilitate their shoulder for several months.
People with a torn tendon can usually function normally and do not require surgery, but many still opt for surgery because a torn tendon decreases their arm strength. Those who have tears at the elbow are more likely to require surgery, according to the Cleveland Clinic.
People with a torn distal biceps tendon should get surgery quickly if they want it because this injury causes scarring that makes surgery problematic after a few weeks, reports the Cleveland Clinic. It may take two to three months of physical therapy after surgery for the tendon to heal.
