Abstract:

Background:

Outcomes after arthroscopic pancapsular capsulorrhaphy (APC) with suture anchors for multidirectional instability (MDI) of the shoulder are not widely reported.

Purpose:

To compare intraoperative findings and midterm outcomes of APC with suture anchors for MDI between female and male athletes and between a classic, atraumatic onset versus clinical onset of MDI after a traumatic event.

Study design:

Cohort study; Level of evidence, 3.

Methods:

Patients who underwent APC with suture anchors for MDI and were at least 2 years out from surgery were included. Data were prospectively collected and retrospectively reviewed and included the onset of MDI, intraoperative pathoanatomic findings, level of sports participation, and patient satisfaction as well as the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), and Short Form-12 Physical Component Summary (SF-12 PCS) scores. Information regarding shoulder instability and return to sport was collected, and Kaplan-Meier survivorship analysis was performed.

Results:

Forty-one patients (45 shoulders; 25 male, 20 female), consecutively treated between October 2006 and January 2013, were included. The onset of MDI was atraumatic in 22 shoulders and traumatic in 23 shoulders. At surgery, 29 of 45 (64.4%) had labral detachment. Seven shoulders (16.7%) experienced instability episodes postoperatively, and 3 of these underwent revision surgery. The mean follow-up was 3.3 years (range, 2.0-6.6 years). All subjective outcome scores improved significantly from preoperative levels (P < .005). At final follow-up, the mean ASES score was 92.0, and 76.7% (23/30) indicated that they had returned to sports participation equal to or slightly below their preinjury level. Kaplan-Meier analysis showed a survivorship rate of 87% at 3 years. Male patients were 2.3 times more likely to have a traumatic onset of instability (68% vs 30%, respectively; P = .017) and were 2.1 times more likely to have concomitant lesions (84% vs 40%, respectively; P = .004) than female patients. Furthermore, male patients demonstrated a higher mean postoperative ASES score than female patients (97.0 ± 4.7 vs 85.5 ± 16.4, respectively; P = .023). Female patients were 6.9 times more likely to undergo an additional rotator interval closure (RIC) procedure (58% vs 4.7%, respectively; P < .001) and to experience postoperative subluxations (40% vs 22%, respectively; P = .035) than male patients. A traumatic onset of MDI was associated with a higher mean postoperative ASES score (96.4 ± 6.9 vs 87.0 ± 15.7, respectively; P = .048), higher median satisfaction score (10 vs 9, respectively; P = .029), and higher return-to-sport rate (83% vs 44%, respectively; P = .030) than an atraumatic onset.

Conclusion:

APC with suture anchors can be an effective and safe treatment for patients with MDI. Labral tears were commonly found, even in patients with a classic, atraumatic onset. Male patients and patients with a traumatic onset of MDI had more favorable outcomes. Female patients may be more challenging to treat as they were more likely to undergo an additional RIC procedure and experience postoperative subluxations.

Dr. Millett and his team did a SLAP tear repair and bicep tenodesis on my left shoulder. I use my arms as an artist, and love to swim in the ocean, surf, paddle, and telemark ski. So regaining full use of my shoulder and keeping my bicep attached was very important to me. Now, over two years later, my shoulder has the equivalent range of motion as my other arm and as before the injury, and no pain. After the first three months it felt so good and was so strong that - to my horror - I completely forgot my six-month follow-up.

Not only did Dr. Millett and his team make my arm as good as new, but having had the experience of such kindness and expertise throughout the process of surgery and recovery is like an added shoulder superpower.

Thank you Rita, Brooke, Jason, Sarah, Camille, Olivia, Dr. Millett and everyone! And see you soon when my husband comes in for his knee...

Flawless procedure, Easy recovery

Dr. Millet's repaired my knee and tibia, following a botched operation by a different surgeon. That procedure was virtually pain free and I was weight bearing within a few days. That was 18 years ago and the knee is still strong. A few years after the knee incident, Dr Millet repaired my shoulder. My insurance company approved me for 3 months of disability following that surgery. I was off pain medication in 2 days and had 90% range of motion within a week. I withdrew my disability claim and returned to work within two weeks of surgery. I’m not a famous athlete—just a regular guy. Nonetheless, I was treated like an NFL at the Steadman clinic. Most notable was the time for recovery. Other surgeons perform their hour-long task in the OR and don’t involve themselves in the other functions. Peter and his team manages the entire process from diagnosis, anesthesia, nursing care, and therapy. He takes a holistic approach to patient care and doesn’t skip any steps.

Saved My Life

I went to Dr. Millett after 7 knee surgeries (6 on my right and 1 on my left) and had seen 11 different surgeons who all refused to remove femur metal from my right leg. I am highly allergic to metal and the chronic pain was leaving me bedridden for 3.5wks out of a month. He personally wrote me back on my inquiry, listened to my concerns, scheduled my surgery within a week (due to insurance issues) and personally followed up with my recovery. The level of patient care from Dr. Millett and his ENTIRE team is above any care I have ever received in my 20 years of dealing with orthopedic surgeons. There are not enough words to describe the level of care, dedication and professionalism you receive from Dr. Millett and his staff.
My only disappointment is that I did not find him sooner!!!
