Short-term outcomes following mini-open repair of chronic gluteus medius tendon tears using a double-row technique

Repair of Full-Thickness Gluteus Maximus Tear With Suture Anchors

Gluteal tendon tears are a common cause of hip pain. Most commonly, tears occur in the gluteus medius and minimus, and there are well-established nonoperative or operative treatment pathways. In this Technical Note, we describe our technique for repair of a full-thickness gluteus maximus tendon tear using anchor fixation.

41-75% of Patients Achieve a Patient Acceptable Symptomatic State After Endoscopic Repair of Hip Abductor Tendon Tears: A Systematic Review

PURPOSE

To systematically review clinical and functional outcomes of endoscopic repairs of hip abductor tendon tears.

METHODS

A search following guidelines established by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses was performed in the PubMed, Embase, and Cochrane databases using variations of the terms "endoscopy," "gluteus medius," "hip abductor," "outcome," "success," and "failure." Data for patient demographics, tear severity and location, patient-reported outcomes (PROs), clinical benefit, and rates of retears and revision surgery were collected and tabulated. Forest plots depicting preoperative versus postoperative PROs were generated. Quality assessment was performed using the modified Coleman Methodology Score.

RESULTS

In total, 13 studies, 3 Level III and 10 Level IV, were included in this review, with a total of 272 patients whose ages ranged from 46.0 to 66.9 years and follow-up times from 16.4 to 46.7 months. Most tears were isolated to the gluteus medius, with the number of partial- versus full-thickness tears being similar. Trendelenburg gait, reported by 4 studies, persisted in 0% to 13.6% of patients after repair. Of 9 studies reporting both preoperative and postoperative PROs at latest follow-up, 8 reported significant improvements in all PROs (P < .05). In 5 studies, rates of achieving minimal clinically important difference and patient-acceptable symptomatic state ranged from 50.0% to 93.3% and 40.7% to 75.0%, respectively. Surgical complication rates were 0% in 11 studies and 4.3% and 18.2% in 2 studies. Retear rates were 0% in 10 studies and ranged from 6.7% to 33.3% in 3 studies. Rates of revision due to retear, reported by 12 studies, were 0% in 8 studies and ranged from 2.2% to 13.0% in 4studies.

CONCLUSIONS

Endoscopic repairs of both partial- and full-thickness hip abductor tendon tears have good-to-excellent PROs and low complication, retear, and revision rates. However, rates of minimal clinically important difference and patient-acceptable symptomatic state achievement rates are highly variable and less than favorable.

LEVEL OF EVIDENCE

Level IV, a systematic review of Level III and IV studies.

Good clinical outcomes, a high level of patient satisfaction and an acceptable re-operation rate are observed 7-10 years after augmented hip abductor tendon repair

PURPOSE

To investigate the clinical outcome, level of patient satisfaction, re-injury and re-operation rates of patients 7-10 years after augmented hip abductor tendon repair.

METHODS

Between October 2012 and May 2015, 146 patients were referred to the senior author with symptomatic hip abductor tendon tears, of which 110 (101 female, 92%) were included in the current study and underwent hip abductor tendon repair augmented with LARS. Patients had a mean age of 63.2 years (range 43-82), body mass index of 27.8 (range 20.0-40.2) and duration of symptoms of 3.6 years (range 6 months-18 years). Patient-reported outcome measures (PROMs) were evaluated pre-operatively and at 3, 6, 12 and 24 months, as well as 7-10 years post-operatively, including the Oxford Hip Score (OHS), 12-item Short Form Health Survey (SF-12), a Visual Analogue Pain Scale (VAS) evaluating the frequency (VAS-F) and severity (VAS-S) of hip pain, and patient satisfaction. Adverse events, surgical failures, revisions and subsequent treatments on the ipsilateral hip were reported.

RESULTS

A significant improvement (p < 0.05) was observed for all PROMs and, while a mean deterioration was observed for all PROMs from 24 months to final review (7-10 years), these were not significant (n.s.). In the 90 patients retained and assessed at final review, 93% were satisfied with their hip pain relief and 89% with their ability to participate in recreational activities. Overall, 9 (of 110, 8.2%) surgical failures were observed over the 7-10-year follow-up period.

CONCLUSIONS

Good clinical scores, a high level of patient satisfaction and an acceptable re-injury rate were observed at 7-10 years after augmented hip abductor tendon repair, demonstrating satisfactory repair longevity.

A Review of Abductor Tendon Tears: The Hidden Lesion of the Hip

»

Greater trochanteric pain syndrome consists of a group of associated conditions involving the lateral hip that can be debilitating to patients, mostly women between ages 40 and 60 years.

»

Abductor tendon tears are becoming a more recognized cause of lateral hip pain in patients without hip osteoarthritis.

»

Diagnosis of this condition is critical to patient care because misdiagnosis often leads to unnecessary prolonged pain and even unnecessary procedures that address different pathologies.

»

Treatment strategies consists of nonoperative modalities such as nonsteroidal anti-inflammatory medications, corticosteroid injections, and physical therapy, but for refractory cases, surgical techniques including repair, augmentation, and reconstruction have been well-described in the literature providing patients with acceptable outcomes.
