Under age 40, repair is typically adviseable, but with increasing age, or when the tendon itself is badly damaged, repair is not a good option since pain may not resolve.In such cases the tendon is released (biceps tenotomy) or tenodesed(sewn to bone). There is an article on this page addressing these options.
SLAP repairs are performed arthroscopically. Postoperatively a sling is worn for 4 weeks. Active elbow flexion is avoided for a few weeks, and shoulder forward flexion and external rotation are also restricted a bit for the first 4 weeks.
