Radiofrequency Microdebridement as an Adjunct to Arthroscopic Surgical Treatment for Recalcitrant Gluteal Tendinopathy: A Double-Blind, Randomized Controlled Trial

The effect of iliotibial band surgery at the hip: a systematic review

BACKGROUND

Current literature presents a variety of surgical interventions aimed at modifying the iliotibial band (ITB) at the hip to relieve lateral hip pain (LHP). However, a focus towards the hip abductors as a main driver in LHP has evolved in the last decade, which could influence the indications for isolated ITB surgery. No previous review has been undertaken to evaluate isolated ITB surgery in LHP cases.

PURPOSE

The purpose of this systematic review was to evaluate isolated ITB surgery in LHP patients in relation to pain, snapping, use of non-surgical treatments postoperatively, and repeated surgery.

METHODS

The study was reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The study was registered in Prospero (CRD42021216707) prior to initiation. A systematic search of literature on PubMed and Embase as well as bibliography screening on adult patients undergoing isolated ITB surgery with or without additional bursectomies was performed. Due to the lack of reliable data, no meta-analysis was performed.

RESULTS

A total of 21 studies (360 patients) were considered eligible for inclusion. The snapping and non-snapping group consisted of 150 and 210 patients, respectively. The mean follow-up time in the snapping group was 30 months and 19 months in the non-snapping group. Utilizing different surgical techniques, complete pain relief was not achieved in 12% of patients in the snapping group and 36% of the patients in the non-snapping group. In the snapping group, snapping was eliminated in 95% of patients, and five of 150 patients (3%) had repeated surgery. Eight of nine non-snapping studies reported information regarding repeated surgery, in which seven of 205 patients (3%) received repeated surgery.

CONCLUSION

ITB surgery at the hip remains widely adopted, although only level 4 studies are available, and little information exists on the long-term clinical, as well as patient reported outcomes. Based on the available data, we found indication of a positive short-term outcome in LHP with snapping regarding elimination of snapping, pain reduction, reuse of non-surgical treatment, and repeated surgery. In LHP with no snapping, we found limited evidence supporting ITB surgery based on current literature.

Platelet-rich plasma versus steroids injections for greater trochanter pain syndrome: a systematic review and meta-analysis

INTRODUCTION

Greater trochanter pain syndrome (GTPS) is characterized by a persistent and debilitating pain around the greater trochanter. GTPS can be caused by a combination of gluteus medius or minimus tendinopathy, snapping hip or trochanteric bursitis.

SOURCE OF DATA

Recent published literatures identified from PubMed, EMBASE, Google Scholar, Scopus.

AREAS OF AGREEMENT

Platelet rich plasma (PRP) and corticosteroids (CCS) injections are useful options to manage symptoms of GTPS.

AREAS OF CONTROVERSY

Whether PRP leads to superior outcomes compared to CCS injections is unclear.

GROWING POINTS

A systematic review and meta-analysis comparing PRP versus CCS in the management of GTPS was conducted.

AREAS TIMELY FOR DEVELOPING RESEARCH

PRP injections are more effective than CCS at approximately 2 years follow-up.

Arthroscopic management of greater trochanter pain syndrome and abductor tears has demonstrated promising results in terms of improvement in pain scores and functional outcomes: a scoping review

PURPOSE

Greater trochanteric pain syndrome (GTPS) refers to the constellation of signs and symptoms related to pain in the trochanteric region and has recently replaced the previously ubiquitous term of 'greater trochanteric bursitis'. GTPS is common, particularly in women 50-79 years of age, and the understanding and management of GTPS have expanded considerably in recent years to include management with arthroscopic and endoscopic techniques in recalcitrant cases. The purpose of this scoping literature review was to summarize the current evidence on arthroscopic management of GTPS including sources of evidence, key concepts, and gaps in the literature.

METHODS

A thorough electronic database search included studies published from 2009 to June 14, 2020. A total of 52 peer-reviewed articles were identified within the literature on arthroscopic or endoscopic management of GTPS.

RESULTS

Of the 52 identified papers, 12 were technique descriptions, 10 papers were review articles, and 30 papers were original clinical papers. Of the 30 clinical papers, 24 (80%) were of level IV evidence, 5 (17%) were of level III evidence, and 1 (3%) was level II evidence. Among the 30 clinical studies, 988 patients were included with 761 (77%) female. Indications for surgical management included a failed trial of conservative management in all 30 studies, typically after a period of 3-6 months. Surgical management consisted of arthroscopic/endoscopic abductor tendon repair in 16 (53%) studies, arthroscopic/endoscopic bursectomy and iliotibial band release in 12 (40%) studies, and arthroscopic/endoscopic gluteal tendon contracture release in 2 (7%) studies.

CONCLUSION

Overall, results following arthroscopic management of GTPS and abductor tears have been promising, including significantly improved pain scores and functional outcomes at final post-operative assessment. These studies support continued use and investigation of arthroscopic management strategies of GTPS and pave the way to conduct larger prospective studies to confirm these results in the future.

Treatment of Gluteal Tendinopathy: A Systematic Review and Stage-Adjusted Treatment Recommendation

Background:

Gluteal tendinopathy is the most common lower limb tendinopathy. It presents with varying severity but may cause debilitating lateral hip pain.

Purpose:

To review the therapeutic options for different stages of gluteal tendinopathy, to highlight gaps within the existing evidence, and to provide guidelines for a stage-adjusted therapy for gluteal tendinopathy.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

We screened Scopus, Embase, Web of Science, PubMed, PubMed Central, Ovid MEDLINE, CINAHL, UpToDate, and Google Scholar databases and databases for grey literature. Patient selection, diagnostic criteria, type and effect of a therapeutic intervention, details regarding aftercare, outcome assessments, complications of the treatment, follow-up, and conclusion of the authors were recorded. An assessment of study methodological quality (type of study, level of evidence) was also performed. Statistical analysis was descriptive. Data from multiple studies were combined if they were obtained from a single patient population. Weighted mean and range calculations were performed.

Results:

A total of 27 studies (6 randomized controlled trials) with 1103 patients (1106 hips) were included. The mean age was 53.7 years (range, 17-88 years), and the mean body mass index was 28.3. The ratio of female to male patients was 7:1. Radiological confirmation of the diagnosis was most commonly obtained using magnetic resonance imaging. Reported treatment methods were physical therapy/exercise; injections (corticosteroids, platelet-rich plasma, autologous tenocytes) with or without needle tenotomy/tendon fenestration; shockwave therapy; therapeutic ultrasound; and surgical procedures such as bursectomy, iliotibial band release, and endoscopic or open tendon repair (with or without tendon augmentation).

Conclusion:

There was good evidence for using platelet-rich plasma in grades 1 and 2 tendinopathy. Shockwave therapy, exercise, and corticosteroids showed good outcomes, but the effect of corticosteroids was short term. Bursectomy with or without iliotibial band release was a valuable treatment option in grades 1 and 2 tendinopathy. Insufficient evidence was available to provide guidelines for the treatment of partial-thickness tears. There was low-level evidence to support surgical repair for grades 3 (partial-thickness tears) and 4 (full-thickness tears) tendinopathy. Fatty degeneration, atrophy, and retraction can impair surgical repair, while their effect on patient outcomes remains controversial.
