REPAIR OF ANTERIOR INSTABILITY
ARTHROSCOPIC OR OPEN BANKART PROCEDURE, LATARJET PROCEDURE

for patients of DAVID LINTNER, MD

Patients who have suffered a traumatic subluxation and/or dislocation with residual pathologic shoulder laxity will undergo this type of procedure. There are several different surgical procedures that can be performed for this injury. During a Bankart or capsulolabral reconstruction, the capsule must be reattached in the correct anatomical location. It may also be necessary to perform a capsular repair to restore adequate tension to the inferior gleno-humeral ligament in order to obtain appropriate joint stability. The primary goal for the therapist following this surgery is to eventually restore adequate and sufficient ROM in order for the patient to perform all desired activities.

Several factors will govern the protocol following surgery to correct a torn/injured capsulolabral complex. First and foremost, the therapist must be aware of the extent of the injury and the exact procedure performed. It is not uncommon to perform a Bankart and capsular shift procedure concomitantly. Protection of the repair is of utmost importance during the rehab process. Stress to the anterior capsule should be avoided initially. ROM limitations must be observed. The second factor is how the procedure was performed – openly or arthroscopically. Loss of motion following ATS is very uncommon. Following open procedures, due to the increased fixation as well as increased pain, loss of motion is often a problem and the therapist should be more aggressive in attaining full ROM. The therapist should also be aware of the method of fixation used (e.g., suture anchors, sutures). Each method obtains a different strength of fixation and rehab should progress with this knowledge in mind. Dr. Lintner uses suture anchors to fixate the capsule to the bone. For open repairs or Latarjet procedures a portion of the subscapularis muscle is also divided from the lateral tendon insertion for the repair to be made and then sutured back to the bone after the repair is complete. This must be taken into account following surgery by avoiding stress to the subscapularis muscle initially.

Fourthly, tissue status must be considered. This can be obtained from the surgical op-report. Rehab will vary based on whether the patient’s capsule is thick and healthy or thin and porous.

The therapist must also consider the demands for the patient’s desired activities as well as work demands. It is imperative that the patient has the strength and ROM necessary for those activities.

Suggestions during rehab:

1. The RC gets a better blood supply when the shoulder is slightly away from the body; therefore, advocate the use of a towel roll under the arm when in a resting position.
2. The RC muscles are very small; therefore, we use lower intensities to isolate each muscle without recruitment from surrounding larger muscles. Focus on hypertrophy initially by high volume (V= Reps X intensity/weight). Following the hypertrophy phase, strength is the focus with lower reps and higher intensities/weight.
3. We now use closed chain rotator cuff exercises using the DS2 Platform to facilitate cuff strength and shoulder proprioception. Like closed chain exercises for the knee, these can be safely initiated early in the post op course.

PHASE ONE

(Week 1-3)
In phase one, the general goals are to protect the surgical repair, initiate ROM to prevent adhesions and increase circulation, decrease pain and inflammation, and stress emphasis of HEP.

A sling will be worn for 4 to 6 weeks unless instructed otherwise by Dr. Lintner.

The sling is to be removed to perform following exercises 2-3X/Day.
