Shoulder adolescent MDI, post-op from arthroscopic capsulolabral tightening / balanced capsulorrhaphy

You or your child had just undergone shoulder arthroscopic stabilization for multidirectional instability (MDI) with Kemble Wang. This means that the shoulder joint was unstable and "loose" in multiple directions, usually with a large/stretchy joint capsule. The condition is more likely to occur in younger adults or adolescents with a history of stretchy joints (ligamentous laxity). Symptoms include instability, frequent dislocations on minor movements, or even just pain and a vague discomfort.


During the procedure Kemble would have arthroscopically "tightened" your shoulder capsule with sutures and bioabsorbable anchors which has the effect of stabilizing the shoulder. There would be several key-hold wounds that are closed with absorbable sutures and dressed with dermabond (skin glue) and water-resistant dressings. 

The following is a schematic diagram of an arthroscopic stabilization for MDI, involving capsulolabral tightening and capsular shift:​​

    • sling most of the time except exercises

    • Work on deltoid and cuff isometrics

    • Active, AAROM in shoulder flex/ext plane, but not past 45 deg

    • No shoulder abduction

    • No ER

    • sling full time otherwise

  • Weeks 6-10 postop

    • Go SLOW

    • DO NOT PUSH through pain to regain motion

    • No Assisted shoulder ER past 0 degrees
