Shoulder adhesive capsulitis: manipulation and arthroscopic arthrolysis or intra-articular steroid injections?

AAOS 2024 best paper in the shoulder and elbow classification: watchful waiting provides higher value with similar functional outcomes to physical therapy for frozen shoulder: a prospective randomized controlled trial

BACKGROUND

Physical therapy remains a ubiquitous treatment modality for the management of frozen shoulder (adhesive capsulitis) despite limited high-level evidence supporting its use. Leveraging patient-reported outcome measures (PROMs) and healthcare costs, this study compared patient outcomes and value achieved through watchful waiting (WW) vs. physical therapy (PT) for conservative management of frozen shoulder.

METHODS

Patients in this prospective, parallel randomized controlled trial who were diagnosed with frozen shoulder were randomized 1:1 to WW or PT. All patients were offered therapeutic, intra-articular corticosteroid injections (CSIs). The primary outcome was the American Shoulder and Elbow Surgeons Score. Secondary outcomes included patient value (ie, 12-month American Shoulder and Elbow Surgeons score divided by healthcare costs), the Disabilities of the Arm, Shoulder, and Hand questionnaire, and Visual Analog Scale pain. Due to the confidentiality of internal hospital data, all economic outcomes were divided by an undisclosed constant to set the normalized study mean for direct costs to 1000; similarly, patient value was normalized to set the study mean to 100. Outcomes were assessed at baseline, 6 weeks, 3 months, 6 months, and 12 months using mixed-effects models, with sensitivity analyses adjusting for nonlinear improvement trajectories and CSIs.

RESULTS

Between November 2014 and November 2022, 175 patients were screened, 61 of whom (34.9%) were randomized to WW (31 patients) or PT (30 patients). Forty-seven patients (96%) received at least one CSI, with no significant difference in CSI administration between cohorts (P = .29). Relative to baseline scores, patients from both cohorts improved significantly at each time point for all PROMs (P < .05 for all), with no significant differences in PROMs between groups at any time point (P > .05 for all). However, compared to those assigned WW, patients randomized to PT incurred 10.0× higher costs (normalized mean difference: 1636; 95% CI: 967, 2304; P < .001) and achieved only 16.9% of the patient value (normalized mean difference: -147.0; 95% CI: -207.5, -86.5; P < .001). These results held across all sensitivity analyses.

CONCLUSION

Relative to WW, patients randomized to PT reported similar PROMs but incurred significantly higher direct costs (10.0×) and imposed a greater economic burden on the healthcare system (3.4-6.0×). Accordingly, WW resulted in significantly higher (5.9×) patient value than PT. Although additional high-level, multicenter studies are needed to corroborate these findings, the present study may support physicians and patients in pursuing the most appropriate treatment plan for each patient based on their individualized needs and preferences.

British Elbow and Shoulder Society patient care pathway: Frozen shoulder

Background

Current guidelines from the British Elbow and Shoulder Society (BESS) were published in 2015 for managing frozen shoulders in the primary and secondary care setting. Updated guidelines have been developed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) methodology.

Methods

A multi-disciplinary BESS Working Group defined key management questions based on agreed outcome measures and time points. A literature search, conducted up to March 2023 following PRISMA guidelines, identified randomised controlled trials, systematic reviews, and meta-analyses. Quality assessments were performed using the GRADE Decision Framework, considering bias, imprecision, indirectness, and inconsistency. Data were extracted for meta-analysis. In the absence of high-quality trials, narrative reviews were created.

Results

Consensus opinions produced statements based on the quality and volume of evidence and the magnitude of desirable and undesirable effects. These statements form a comprehensive framework for managing frozen shoulder.

Discussion

This updated guideline provides evidence-based guidance for managing frozen shoulder and identifies key areas for future research.

The statistical fragility of treatments for adhesive capsulitis: a systematic review of randomized controlled trials

BACKGROUND

Randomized controlled trials (RCTs) have assessed a range of treatments for shoulder adhesive capsulitis (AC), with conflicting results over the most clinically beneficial options. This study used the fragility index (FI), reverse fragility index (rFI), and fragility quotient (FQ) to evaluate statistical fragility of the outcomes reported in RCTs assessing the efficacy of shoulder AC treatments.

METHODS

PubMed and Embase were systematically searched for RCTs from January 1, 2004, to May 1, 2024 that assessed shoulder AC treatments. We quantified FI and rFI, which represent the amount of outcome event reversals necessary to change statistical significance for significant and nonsignificant findings, respectively. Subanalyses were performed for outcomes relating to clinical efficacy, patient satisfaction, pain, and adverse events. The FQ was determined by dividing the FI by the study sample size.

RESULTS

Of 468 articles screened, there were a total of 38 RCTs analyzed that yielded 67 outcomes of interest. Across the 67 outcomes, the median FI was 3 (interquartile range [IQR] 2-6) and the median FQ was 0.075 (IQR 0.034-0.100). The 17 statistically significant outcomes had a median FI of 2 (IQR 1-4) and a median FQ of 0.050 (IQR 0.018-0.091). The remaining 50 outcomes were statistically nonsignificant, with a median FI of 4 (IQR 2-6) and a median FQ of 0.079 (IQR 0.037-0.102). Notably, in 40.3% of all outcomes, loss-to-follow-up was greater or equal to the outcome's respective FI or rFI. The most fragile outcomes were related to patient satisfaction (FI 2) and adverse events (FI 2.5).

CONCLUSION

The outcomes of interest regarding treatments for AC from RCTs are statistically fragile, most notably significant outcomes and those pertaining to patient satisfaction. RCT results surrounding AC treatments remain inconclusive; thus, combining P values with both FI and FQ metrics may improve the interpretation of clinical findings regarding treatment modalities for AC. Future clinical RCTs may reduce outcome fragility by improving follow-up rates and increasing patient sample sizes.

The S2e Guideline on Shoulder Stiffness

The clinical picture of "frozen shoulder" is still poorly understood. In order to present the current state of knowledge on aetiology, diagnosis, and treatment, and to provide recommendations for the professional groups involved, a working group was formed by the DGOU and the DVSE to create a German language, evidence-based guideline, which was published in 2022 by the AWMF. The following summarises the development and the most important results.

Arthroscopic capsular release is more effective in pain relief than conservative treatment in patients with frozen shoulder

BACKGROUND

Frozen shoulder is a common medical condition, but the ideal therapeutic method is yet to be determined. Our aim was to analyze the pain-relieving effect of different treatment options used for the management of this disease.

METHODS

Medical records of 59 patients (22 male, 37 female, average age: 55.5 years ±9.9) with early stage primary frozen shoulder were evaluated, their demographic data, physical examination, concomitant diseases and treatment specific data were registered. Life quality and the level of pain were assessed using the Oxford Shoulder Score (OSS) and Numeric Rating Scale (NRS). Different treatment modalities and their effect on pain relief were recorded. Any existing correlation between life quality, pain and demographic data, concomitant diseases or the therapeutic method used was investigated.

RESULTS

The level of pain measured on NRS improved from 7.9 ± 1.6 to 1.9 ± 2.2. The most effective therapeutic method in terms of pain relief was surgery, followed by physiotherapy and intraarticular steroid injection (NRS score after treatment: 2 - p < 0.0001; 3.3 - p < 0.0001; 4.9 - p < 0.0001, respectively). Non-steroidal anti-inflammatory drugs (NSAIDs) did not reduce pain significantly. OSS improved from 24 to 43.6 and was not affected by the investigated variables, time to recovery was not influenced by the demographic data, the type of treatment or concomitant diseases.

CONCLUSIONS

Arthroscopic capsular release, physiotherapy and intraarticular steroid injection outperformed physical therapy and NSAID treatment in terms of pain relief. Despite of slight but persistent post-therapeutic pain found in half of the cases, treatment was considered satisfactory by the patients. Nor patient specific neither therapy specific data had a significant effect on the course of the disease.

A multi-center, single-blinded, randomized, parallel-group, superiority study to compare the efficacy of manipulation under anesthesia versus intra-articular steroid injection in the treatment of patients with frozen shoulder and a diagnosis of rotator cuff injury or tear by MRI: study protocol for a randomized controlled trial

BACKGROUND

Frozen shoulder (FS) is a common condition that can cause severe pain and limited range of motion in the shoulder joint. While intra-articular steroid injection has been shown to be an effective treatment for FS, manipulation under anesthesia (MUA) is an alternative treatment that has gained popularity in recent years. However, there is a lack of evidence regarding the effectiveness of MUA on FS patients with concomitant rotator cuff injury or tear. Though a few studies have shown that MUA is not associated with rotator cuff tears, and will not exacerbate the injury, more high-quality studies with bigger sample sizes are needed. Therefore, the aim of this multi-center, single-blinded, randomized, parallel-group, superiority study is to compare the efficacy of MUA versus intra-articular steroid injection in the treatment of FS patients with a diagnosis of rotator cuff injury or tear by MRI.

METHODS

A parallel, single-blinded, multi-center randomized controlled trial of 320 patients will be conducted at three hospitals of China. Eligible patients with frozen shoulder and rotator cuff injury or tear diagnosed by MRI will be randomly assigned to, in equal proportions, the manipulation under anesthesia group and the intra-articular steroid injection group via a central randomization system, undergoing a corresponding operation on day one and a sequent physical exercise for 14 days. The primary outcome is the comprehensive efficacy evaluation (total effective rate) and the change of Constant-Murley Score. Outcome assessors and data analysts will be blinded, and participants will be asked not to reveal their allocation to assessors.

DISCUSSION

This study aims to explore the superiority of manipulation under anesthesia in reducing pain and improving shoulder function in frozen shoulder patients accompanied with rotator cuff injury. To provide a scientific basis for the dissemination and application of manipulation under anesthesia, and a better knowledge for the role of MUA in the treatment of frozen shoulder accompanied with rotator cuff injury.

Comparing surgical outcomes of anterior capsular release vs circumferential release for persistent capsular stiffness

Purpose

To consolidate the existing literature evaluating anterior capsular release and circumferential capsular release in the treatment of adhesive capsulitis (AC) of the shoulder.

Methods

The electronic databases PUBMED, EMBASE, MEDLINE and CENTRAL (Cochrane Central Register of Controlled Trials) were searched from data inception to October 8, 2020. Data are presented descriptively where appropriate. A meta-analysis was conducted for patient-reported outcomes.

Results

Overall, there were forty-six articles included. The majority of patients underwent circumferential release compared to anterior release (80.1% vs. 19.9%). Concomitant Manipulation Under Anesthesia (MUA) was employed in 25 studies, with a higher occurrence in the anterior compared to the circumferential release group (70% vs 60%). Both groups experienced significant improvements postoperatively in range of motion (ROM) and patient-reported outcomes. Complication rates were low for both anterior release (0.67%) and 360° release (0.44%).

Conclusion

Both anterior and circumferential release are effective techniques for treating AC with low complication rates. Future studies should improve documentation of patient demographics, surgical techniques and outcomes to determine an individualized treatment protocol for patients.

Combined arthroscopic release with corticosteroid hydrodilatation versus corticosteroid hydrodilatation only in treating freezing-phase primary frozen shoulder: a randomized clinical trial

BACKGROUND

There has been no ideal treatment for freezing-phase frozen shoulder to rapidly relieve pain and improve joint mobility. No any other team directly compared the effectiveness of combination of arthroscopic release and corticosteroid hydrodilatation with corticosteroid hydrodilatation only in treatment of freezing-phase frozen shoulder.

METHODS

Seventy-two patients with freezing-phase frozen shoulder were randomly assigned to combined arthroscopic release with corticosteroid hydrodilatation (group A) or corticosteroid hydrodilatation only (group B). Clinical states were examined at baseline and periodically (Weeks 1, 4, 12, 24 and 1 year) after intervention by passive ROM; visual analog scale (VAS); UCLA and Disabilities of the Arm, Shoulder, and Hand (DASH) score.

RESULTS

The passive ROM, VAS, UCLA and DASH scores always improved along the time points (all p < 0.01). The passive abduction (pAB), passive forward flexion (pFL), passive external rotation (pER), passive internal rotation (pIR) were better in group A than in group B at Week 1, 4, 12, 24 (all p < 0.01). At 1 year post-operation, the pFL and pIR were better in group A than in group B (all p < 0.01). VAS scores of group A were similar with those of group B (all p > 0.01), the differences between group A and group B were all lower than minimal clinically important difference (MCID). At Week 12, the UCLA sores and DASH scores were 26.8 ± 3.8, 14.2 ± 2.0 in group A versus 22.3 ± 3.4, 22.5 ± 3.1 in group B (all p < 0.01). At Week 24 post-operation, there were 32.7 ± 2.0, 9.8 ± 1.5 in group A versus 26.3 ± 3.6, 17.5 ± 3.5 in group B (all p < 0.01). At 1 year post-operation, there were 34.5 ± 0.8, 1.7 ± 1.5 in group A versus 32.1 ± 2.3, 8.8 ± 2.8 in group B (all p < 0.01), the differences of UCLA scores between group A and group B at Week 24 was higher than the MCID. There were no complications such as infection, nerve or vascular injury.

CONCLUSIONS

Combined arthroscopic release with corticosteroid hydrodilatation would yield better results in passive ROM and function than corticosteroid hydrodilatation only.

Factors related to initial treatment for adhesive capsulitis in the medicare population

BACKGROUND

Primary adhesive capsulitis (AC) is not well understood, and controversy remains about the most effective treatment approaches. Even less is known about the treatment of AC in the Medicare population. We aimed to fully characterize initial treatment for AC in terms of initial treatment utilization, timing of initial treatments and treatment combinations.

METHODS

Using United States Medicare claims from 2010-2012, we explored treatment utilization and patient characteristics associated with initial treatment for primary AC among 7,181 Medicare beneficiaries. Patients with primary AC were identified as patients seeking care for a new shoulder complaint in 2011, with the first visit related to shoulder referred to as the index date, an x-ray or MRI of the shoulder region, and two separate diagnoses of AC (ICD-9-CM codes: 726.00). The treatment period was defined as the 90 days immediately following the index shoulder visit. A multivariable logistic model was used to assess baseline patient factors associated with receiving surgery within the treatment period.

RESULTS

Ninety percent of beneficiaries with primary AC received treatment within 90 days of their index shoulder visit. Physical therapy (PT) alone (41%) and injection combined with PT (34%) were the most common treatment approaches. Similar patient profiles emerged across treatment groups, with higher proportions of racial minorities, socioeconomically disadvantaged and more frail patients favoring injections or watchful waiting. Black beneficiaries (OR = 0.37, [0.16, 0.86]) and those residing in the northeast (OR = 0.36, [0.18, 0.69]) had significantly lower odds of receiving surgery in the treatment period. Conversely, younger beneficiaries aged 66-69 years (OR = 6.75, [2.12, 21.52]) and 70-75 years (OR = 5.37, [1.67, 17.17]) and beneficiaries with type 2 diabetes had significantly higher odds of receiving surgery (OR = 1.41, [1.03, 1.92]).

CONCLUSIONS

Factors such as patient baseline health and socioeconomic characteristics appear to be important for physicians and Medicare beneficiaries making treatment decisions for primary AC.

[Surgical treatment of arthrofibrosis of the knee joint]

Die Arthrofibrose des Kniegelenks ist eine schwerwiegende Komplikation nach Trauma und Operation, da die Funktion des Gelenks häufig dauerhaft beeinträchtigt wird. Es werden nach wie vor frühzeitige Mobilisierungstechniken und die Anästhesie eingesetzt, ohne dass die zugrunde liegenden Prozesse ausreichend aufgeklärt wurden. Während die Frühphase der Arthrofibrose gut auf konservative Maßnahmen zur Schmerzreduktion und zur Wundheilungsregulation anspricht, ist in der Spätphase häufig straffes kollagenes Narbengewebe vorhanden, das die Beweglichkeit dauerhaft einschränkt. In dieser Phase ist eine Verbesserung der Beweglichkeit ohne chirurgische Maßnahmen in der Mehrzahl der Fälle aussichtslos. Bei einer chirurgischen Therapie sollte zwischen der lokalisierten (zumeist sekundären) Arthrofibrose (z. B. Kreuzbandoperation) und einer generalisierten Arthrofibrose (primär, in der Mehrzahl der Fälle nach einer Knietotalendoprothese [Knie-TEP]) unterschieden und die Behandlung entsprechend geplant werden. Begleitende pathologische Veränderungen (Transplantatposition, Instabilität der TEP, Implantatverschleiß, „Low-grade“-Infektion, patellofemorale Instabilität oder „maltracking“, Patella baja) müssen bei der Behandlung berücksichtigt werden. Eine multimodale Begleitbehandlung (Physiotherapie, Schmerztherapie, Psychosomatik) ist zur Sicherung des Behandlungserfolgs notwendig.

Effectiveness of interventions for the management of primary frozen shoulder : a systematic review of randomized trials

AIMS

This systematic review places a recently completed multicentre randomized controlled trial (RCT), UK FROST, in the context of existing randomized evidence for the management of primary frozen shoulder. UK FROST compared the effectiveness of pre-specified physiotherapy techniques with a steroid injection (PTSI), manipulation under anaesthesia (MUA) with a steroid injection, and arthroscopic capsular release (ACR). This review updates a 2012 review focusing on the effectiveness of MUA, ACR, hydrodilatation, and PTSI.

METHODS

MEDLINE, Embase, PEDro, Science Citation Index, Clinicaltrials.gov, CENTRAL, and the World Health Organization (WHO) International Clinical Trials Registry were searched up to December 2018. Reference lists of included studies were screened. No language restrictions applied. Eligible studies were RCTs comparing the effectiveness of MUA, ACR, PTSI, and hydrodilatation against each other, or supportive care or no treatment, for the management of primary frozen shoulder.

RESULTS

Nine RCTs were included. The primary outcome of patient-reported shoulder function at long-term follow-up (> 6 months and ≤ 12 months) was reported for five treatment comparisons across four studies. Standardized mean differences (SMD) were: ACR versus MUA: 0.21 (95% confidence interval (CI) 0.00 to 0.42), ACR versus supportive care: -0.13 (95% CI -1.10 to 0.83), and ACR versus PTSI: 0.33 (95% CI 0.07 to 0.59) and 0.25 (95% CI -0.34 to 0.85), all favouring ACR; MUA versus supportive care: 0 (95% CI -0.44 to 0.44) not favouring either; and MUA versus PTSI: 0.12 (95% CI -0.14 to 0.37) favouring MUA. None of these differences met the threshold of clinical significance agreed for the UK FROST and most confidence intervals included zero.

CONCLUSION

The findings from a recent multicentre RCT provided the strongest evidence that, when compared with each other, neither PTSI, MUA, nor ACR are clinically superior. Evidence from smaller RCTs did not change this conclusion. The effectiveness of hydrodilatation based on four RCTs was inconclusive and there remains an evidence gap.

Efficacy of Arthroscopic Surgery in the Management of Adhesive Capsulitis: A Systematic Review and Network Meta-analysis of Randomized Controlled Trials

PURPOSE

To determine which interventions optimize clinical outcomes in adhesive capsulitis by performing a network meta-analysis of randomized controlled trials.

METHODS

A systematic review was conducted of all clinical trials on adhesive capsulitis published since 2008. Patient cohorts were grouped into treatment categories; data collected included range of motion (ROM) and patient-reported outcome measures (PROMs). Interventions were compared across groups by means of arm-based Bayesian network meta-analysis in a random-effects model.

RESULTS

Sixty-six studies comprising 4042 shoulders (57.6% female patients, age 54.8 ± 3.2 years [mean ± standard deviation]) were included. The most commonly studied interventions were physical therapy (PT) or shoulder injections. Network meta-analysis demonstrated that arthroscopic surgical capsular release was the most effective treatment in increasing ROM. This effect was apparent in forward flexion (effect difference [ED] versus placebo, 44°, 95% confidence interval [CI] 31° to 58°), abduction (ED 58°, 45° to 71°), internal rotation (ED 34°, 24° to 44°), and external rotation (ED 59°, 37° to 80°). Interventions most effective for pain relief included PT supplemented with either medical therapy (ED -4.50, -9.80 to 2.80) or ultrasound therapy (ED -5.10, -5.10 to -1.40). Interventions most effective for improvement of functional status included PT, manipulation under anesthesia (MUA), intra-articular or subacromial steroid injection, surgical capsular release, and supplementation of PT with alternative therapy.

CONCLUSIONS

No one treatment emerged superior in regard to ROM, pain symptoms, and functional status. Surgery (after failure of conservative treatment) ranked highest across all ROM domains. Treatments that ranked highest for treatment of pain included PT supplemented with either medical therapy or ultrasound. Finally, treatments that ranked highest for improvements in functional status included MUA, PT with medical therapy, surgical intervention, PT with ultrasound, PT with injection, and injection alone.

The Prognosis of Arthrofibroses: Prevalence, Clinical Shortcomings, and Future Prospects

Fibrosis is the dysregulated biosynthesis of connective tissue that results from persistent infection, high serum cholesterol, surgery, trauma, or prolonged joint immobilization. As a disease that impacts connective tissue, it is prevalent across the body and disrupts normal extracellular and tissue organization. Ultimately, fibrosis impairs the tissue structural, mechanical, or biochemical function. This review describes the clinical landscape of joint fibrosis, that is, arthrofibrosis, including the risk factors and causes, as well as current clinical treatments and their shortcomings. Because treating arthrofibrosis remains an unmet clinical challenge, we present several animal models used for exploration of the physiopathology of arthrofibrosis and summarize their use for testing novel treatments. We then discuss therapeutics for the prevention or treatment of arthrofibrosis that are in preclinical development and in ongoing clinical trials. We conclude with recent findings from molecular biological studies of arthrofibroses that shed insight on future areas of research for improved treatments.

Comparison of Treatments for Frozen Shoulder: A Systematic Review and Meta-analysis

IMPORTANCE

There are a myriad of available treatment options for patients with frozen shoulder, which can be overwhelming to the treating health care professional.

OBJECTIVE

To assess and compare the effectiveness of available treatment options for frozen shoulder to guide musculoskeletal practitioners and inform guidelines.

DATA SOURCES

Medline, EMBASE, Scopus, and CINHAL were searched in February 2020.

STUDY SELECTION

Studies with a randomized design of any type that compared treatment modalities for frozen shoulder with other modalities, placebo, or no treatment were included.

DATA EXTRACTION AND SYNTHESIS

Data were independently extracted by 2 individuals. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Random-effects models were used.

MAIN OUTCOMES AND MEASURES

Pain and function were the primary outcomes, and external rotation range of movement (ER ROM) was the secondary outcome. Results of pairwise meta-analyses were presented as mean differences (MDs) for pain and ER ROM and standardized mean differences (SMDs) for function. Length of follow-up was divided into short-term (≤12 weeks), mid-term (>12 weeks to ≤12 months), and long-term (>12 months) follow-up.

RESULTS

From a total of 65 eligible studies with 4097 participants that were included in the systematic review, 34 studies with 2402 participants were included in pairwise meta-analyses and 39 studies with 2736 participants in network meta-analyses. Despite several statistically significant results in pairwise meta-analyses, only the administration of intra-articular (IA) corticosteroid was associated with statistical and clinical superiority compared with other interventions in the short-term for pain (vs no treatment or placebo: MD, -1.0 visual analog scale [VAS] point; 95% CI, -1.5 to -0.5 VAS points; P < .001; vs physiotherapy: MD, -1.1 VAS points; 95% CI, -1.7 to -0.5 VAS points; P < .001) and function (vs no treatment or placebo: SMD, 0.6; 95% CI, 0.3 to 0.9; P < .001; vs physiotherapy: SMD 0.5; 95% CI, 0.2 to 0.7; P < .001). Subgroup analyses and the network meta-analysis demonstrated that the addition of a home exercise program with simple exercises and stretches and physiotherapy (electrotherapy and/or mobilizations) to IA corticosteroid may be associated with added benefits in the mid-term (eg, pain for IA coritocosteriod with home exercise vs no treatment or placebo: MD, -1.4 VAS points; 95% CI, -1.8 to -1.1 VAS points; P < .001).

CONCLUSIONS AND RELEVANCE

The findings of this study suggest that the early use of IA corticosteroid in patients with frozen shoulder of less than 1-year duration is associated with better outcomes. This treatment should be accompanied by a home exercise program to maximize the chance of recovery.

Surgical treatments compared with early structured physiotherapy in secondary care for adults with primary frozen shoulder: the UK FROST three-arm RCT

BACKGROUND

Frozen shoulder causes pain and stiffness. It affects around 10% of people in their fifties and is slightly more common in women. Costly and invasive surgical interventions are used, without high-quality evidence that these are effective.

OBJECTIVES

To compare the clinical effectiveness and cost-effectiveness of three treatments in secondary care for adults with frozen shoulder; to qualitatively explore the acceptability of these treatments to patients and health-care professionals; and to update a systematic review to explore the trial findings in the context of existing evidence for the three treatments.

DESIGN

This was a pragmatic, parallel-group, multicentre, open-label, three-arm, randomised superiority trial with unequal allocation (2 : 2 : 1). An economic evaluation and a nested qualitative study were also carried out.

SETTING

The orthopaedic departments of 35 hospitals across the UK were recruited from April 2015, with final follow-up in December 2018.

PARTICIPANTS

Participants were adults (aged ≥ 18 years) with unilateral frozen shoulder, characterised by restriction of passive external rotation in the affected shoulder to < 50% of the opposite shoulder, and with plain radiographs excluding other pathology.

INTERVENTIONS

The inventions were early structured physiotherapy with a steroid injection, manipulation under anaesthesia with a steroid injection and arthroscopic capsular release followed by manipulation. Both of the surgical interventions were followed with post-procedural physiotherapy.

MAIN OUTCOME MEASURES

The primary outcome and end point was the Oxford Shoulder Score at 12 months post randomisation. A difference of 5 points between early structured physiotherapy and manipulation under anaesthesia or arthroscopic capsular release or of 4 points between manipulation under anaesthesia and arthroscopic capsular release was judged clinically important.

RESULTS

The mean age of the 503 participants was 54 years; 319 were female (63%) and 150 had diabetes (30%). The primary analyses comprised 473 participants (94%). At the primary end point of 12 months, participants randomised to arthroscopic capsular release had, on average, a statistically significantly higher (better) Oxford Shoulder Score than those randomised to manipulation under anaesthesia (2.01 points, 95% confidence interval 0.10 to 3.91 points; p = 0.04) or early structured physiotherapy (3.06 points, 95% confidence interval 0.71 to 5.41 points; p = 0.01). Manipulation under anaesthesia did not result in statistically significantly better Oxford Shoulder Score than early structured physiotherapy (1.05 points, 95% confidence interval -1.28 to 3.39 points; p = 0.38). No differences were deemed of clinical importance. Serious adverse events were rare but occurred in participants randomised to surgery (arthroscopic capsular release,n = 8; manipulation under anaesthesia,n = 2). There was, however, one serious adverse event in a participant who received non-trial physiotherapy. The base-case economic analysis showed that manipulation under anaesthesia was more expensive than early structured physiotherapy, with slightly better utilities. The incremental cost-effectiveness ratio for manipulation under anaesthesia was £6984 per additional quality-adjusted life-year, and this intervention was probably 86% cost-effective at the threshold of £20,000 per quality-adjusted life-year. Arthroscopic capsular release was more costly than early structured physiotherapy and manipulation under anaesthesia, with no statistically significant benefit in utilities. Participants in the qualitative study wanted early medical help and a quicker pathway to resolve their shoulder problem. Nine studies were identified from the updated systematic review, including UK FROST, of which only two could be pooled, and found that arthroscopic capsular release was more effective than physiotherapy in the long-term shoulder functioning of patients, but not to the clinically important magnitude used in UK FROST.

LIMITATIONS

Implementing physiotherapy to the trial standard in clinical practice might prove challenging but could avoid theatre use and post-procedural physiotherapy. There are potential confounding effects of waiting times in the trial.

CONCLUSIONS

None of the three interventions was clearly superior. Early structured physiotherapy with a steroid injection is an accessible and low-cost option. Manipulation under anaesthesia is the most cost-effective option. Arthroscopic capsular release carries higher risks and higher costs.

FUTURE WORK

Evaluation in a randomised controlled trial is recommended to address the increasing popularity of hydrodilatation despite the paucity of high-quality evidence.

Can manipulation under anesthesia alone provide clinical outcomes similar to arthroscopic circumferential capsular release in primary frozen shoulder (FS)?: the necessity of arthroscopic capsular release in primary FS

Background

We evaluated the need for arthroscopic capsular release (ACR) in refractory primary frozen shoulder (FS) by comparing clinical outcomes of patients treated with ACR and manipulation under anesthesia (MUA).

Methods

We assessed patients with refractory primary FS, 57 patients (group A) who were treated with MUA and 22 patients (group B) who were treated with ACR. In group A, manipulation including a backside arm-curl maneuver was performed under interscalene brachial block. In group B, manipulation was performed only to release the inferior capsule before arthroscopic circumferential capsular release, which was carried out for the unreleased capsule after manipulation. Pain, range of shoulder motion, and American Shoulder and Elbow Surgeons score were recorded at 1 week, 3 months, 6 months, and 1 year after surgery. We compared outcome variables between treatment groups and between diabetics and non-diabetics and also evaluated the numbers of patients receiving additional intra-articular steroid injection.

Results

Outcome variables at 3 months after surgery and improvements in outcome variables did not differ between groups. Group A showed significantly better results than group B in the evaluation of pain and range of motion at 1 week. Diabetics showed comparable outcomes to non-diabetics for most variables. Eleven patients required additional steroid injections between 8 to 16 weeks after surgery: 12.2% in group A, 18.2% in group B. Additional injections were given three times more often in diabetics compared to non-diabetics.

Conclusions

MUA alone can yield similar clinical outcomes to ACR in refractory FS.

Early Clinical Outcomes of Manipulation under Anesthesia for Refractory Adhesive Capsulitis: Comparison with Arthroscopic Capsular Release

Backgroud

The purpose of this study was to compare early clinical outcomes of manipulation under anesthesia (MUA) and arthroscopic capsular release (ACR) in patients with refractory adhesive capsulitis (AC).

Methods

Thirty AC patients who underwent MUA (MUA group) were included. As a control group, thirty AC patients who underwent ACR (ACR group) were matched for age and sex with the MUA group. Visual analog scale (VAS) pain score, American shoulder and Elbow Surgeons (ASES) score, and range of motion (ROM) were evaluated preoperatively and at 3, 6, and 12 months after procedure.

Results

Both groups had significant improvements in the VAS pain score, ASES score, and ROM at 12 months after procedure. VAS pain score and ASES score were significantly better in the MUA group than in the ACR group at 3 months after procedure. Mean forward flexion was significantly greater in the MUA group than in the ACR group at 3 months after procedure. Mean external rotation and internal rotation were significantly greater in the MUA group than in the ACR group at 3, 6, and 12 months after procedure. Two patients required additional steroid injections at 3 and 6 months after MUA because of recurrent stiffness with pain.

Conclusions

Compared with ACR, MUA provided equivalent clinical outcomes in the early period after procedure. Our study suggests that MUA is a useful option to be considered as treatment for refractory AC before choosing ACR.

Outcomes of Arthroscopic Capsular Release in the Beach-Chair Versus Lateral Decubitus Position: A Systematic Review

Background:

Arthroscopic capsular release (ACR) for the treatment of adhesive capsulitis of the shoulder can be performed in either the beach-chair (BC) or lateral decubitus (LD) position.

Purpose:

To determine the clinical outcomes and recurrence rates after ACR in the BC versus LD position.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

A systematic review using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was performed by searching PubMed, Embase, and the Cochrane Library databases for studies reporting clinical outcomes of patients undergoing ACR in either the BC or LD position. All English-language literature from 1990 through 2017 reporting on clinical outcomes after ACR with a minimum 3-month follow-up were reviewed by 2 independent reviewers. Recurrence rates, range of motion (ROM) results, and patient-reported outcome (PRO) scores were collected. Study methodological quality was evaluated using the modified Coleman Methodology Score (MCMS).

Results:

A total of 30 studies (3 level 1 evidence, 2 level 2 evidence, 4 level 3 evidence, 21 level 4 evidence) including 665 shoulders undergoing ACR in the BC position (38.1% male; mean age, 52.0 ± 3.9 years; mean follow-up, 35.4 ± 18.4 months) and 603 shoulders in the LD position (41.8% male; mean age, 53.0 ± 2.3 years; mean follow-up, 37.2 ± 16.8 months) were included. There were no significant differences in overall mean recurrence rates between groups (BC, 2.5%; LD, 2.4%; P = .81) or in any PRO scores between groups (P > .05). There were no significant differences in improvement in ROM between groups, including external rotation at the side (BC, 36.4°; LD, 42.8°; P = .91), forward flexion (BC, 64.4°; LD, 79.3°; P = .73), abduction (BC, 77.8°; LD, 81.5°; P = .82), or internal rotation in 90° of abduction (BC, 40.8°; LD, 45.5°; P = .70). Significantly more patients in the BC group (91.6%) underwent concomitant manipulation than in the LD group (63%) (P < .0001). There were significantly more patients with diabetes in the LD group (22.4%) versus the BC group (9.6%) (P < .0001).

Conclusion:

Low rates of recurrent shoulder stiffness and excellent improvements in ROM can be achieved after ACR in either the LD or BC position. Concomitant manipulation under anesthesia is performed more frequently in the BC position compared with the LD position.

Treatment Strategy for Frozen Shoulder

Frozen shoulder (FS) is a common shoulder disorder characterized by a gradual increase of pain of spontaneous onset and limitation in range of motion of the glenohumeral joint. The pathophysiology of FS is relatively well understood as a pathological process of synovial inflammation followed by capsular fibrosis, but the cause of FS is still unknown. Treatment modalities for FS include medication, local steroid injection, physiotherapy, hydrodistension, manipulation under anesthesia, arthroscopic capsular release, and open capsular release. Conservative management leads to improvement in most cases. Failure to obtain symptomatic improvement and continued functional disability after 3 to 6 months of conservative treatment are general indications for surgical management. However, there is no consensus as to the most efficacious treatments for this condition. In this review article, we provide an overview of current treatment methods for FS.

Manipulation under anaesthesia for frozen shoulders: outdated technique or well-established quick fix?

Manipulation under anaesthesia (MUA) for frozen shoulder (FS) leads to a considerable increase in range of motion and Oxford shoulder score, a significant reduction in pain and around 85% satisfaction.A clearly defined indication for MUA in FS patients cannot be extracted from this review or the available literature. The associating criteria before proceeding to MUA vary widely.All but one study in this review lacked a control group without intervention. Therefore, firm conclusions about the role of MUA in the treatment of FS cannot be drawn from the current literature.An overall complication rate of 0.4% was found and a re-intervention rate of 14%, although most of the included papers were not designed to monitor complications.The following criteria before proceeding to MUA are proposed: a patient unable to cope with a stiff and painful shoulder; clinical signs of a stage 2 idiopathic FS; lessening pain in relation to stage 1; external rotation < 50% compared to contralateral shoulder joint; a minimal duration of symptoms of three months; and failure to respond to an intra-articular corticosteroid infiltration.

Immediate Pain Relief in Adhesive Capsulitis by Acupuncture-A Randomized Controlled Double-Blinded Study

Objective

Primary adhesive capsulitis (AC), or frozen shoulder, is an insidious and idiopathic disease. Severe pain is predominant in the first two of the three stages of the condition, which can last up to 21 months.

Design, Setting, and Subjects

Sixty volunteers with primary AC were randomly assigned to acupuncture with press tack needles compared with press tack placebos in a patient- and observer-blinded placebo-controlled study. The participants were subsequently offered classical needle acupuncture in an open follow-up clinical application. Thirty-four volunteers received conservative therapy, including 10 classical needle acupuncture treatments over 10 weeks, 13 volunteers received conservative therapy without classical needle acupuncture. All subjects agreed to follow-up after one year.

Methods

Acupuncture treatment was performed using a specific distal needling concept, using reflex areas on distant extremities avoiding local treatment.

Results

An immediate improvement of 3.3 ± 3.2 points in Constant-Murley Shoulder Score (CMS) pain subscore was seen in the press tack needles group and of 1.6 ± 2.8 points in the press tack placebos group (P <0.02). Conservative therapy including classical needle acupuncture significantly improved the pain subscore within 14.9 ± 15.9 weeks compared with 30.9 ± 15.8 weeks with only conservative therapy (P < 0.001).

Conclusion

The efficiency of distal needling acupuncture on immediate pain reduction was demonstrated in patients with AC and confirmed the applicability of press tack needles and press tack placebos for double-blind studies in acupuncture. Subsequent clinical application observation proved that results obtained with press tack needles/press tack placebos can be transferred to classical needle acupuncture. Integrating acupuncture with conservative therapy showed superior effectiveness with respect to the time course of the recovery process in AC compared with conservative therapy alone.

Effectiveness of translational manipulation under interscalene block for the treatment of adhesive capsulitis of the shoulder: A nonrandomized clinical trial

Study Design: Nonrandomized controlled trial. Objective: To determine whether translational manipulation under anesthesia/local block (TMUA) adds to the benefit of mobilization and range of motion exercise for improving pain and functional status among patients with adhesive capsulitis of the shoulder (AC). Background: TMUA has been shown to improve pain and dysfunction in patients with AC. This intervention has not been directly compared to physical therapy treatment without TMUA in a prospective trial. Methods: Sixteen consecutive patients with a primary diagnosis of AC were divided into two groups. Patients in the first (TMUA) group received a session of translational manipulation under interscalene block, followed by six sessions of manipulation and exercise. Patients in the comparison group received seven sessions of manipulation and exercise. Outcome measures taken at baseline and 3, 6, 12 months and 4 years included Shoulder Pain and Disability Index (SPADI) scores. Four-year outcomes included percent of normal ratings, medication use, and activity limitations. Results: Both groups showed improved SPADI scores across all follow-up times compared to baseline. The TMUA group showed a greater improvement in SPADI scores than the comparison group at 3 weeks, with no significant differences in SPADI scores at other time points. However, at 4 years, significantly more subjects in the comparison group (5 of 8) had activity limitations versus subjects in the TMUA group (1 of 8). No subject experienced a complication from either intervention protocol. Conclusion: Physical therapy consisting of manual therapy and exercise provides benefit for patients with AC. Translational manipulation under local block may be a useful adjunct to manual therapy and exercise for patients with AC.

MID-LONG TERM RESULTS OF MANIPULATION AND ARTHROSCOPIC RELEASE IN FROZEN SHOULDER

OBJECTIVE

Surgical treatment options should be discussed in cases of frozen shoulder, which is usually treated in a conservative manner. In this study, we evaluated the efficacy of manipulation and arthroscopic release in cases of frozen shoulder which resisted conservative treatment.

METHODS

A total of 32 patients who underwent manipulation and arthroscopic capsular release in 34 shoulders were included in the study. The average follow-up period was 49.5 months (range: 24-90 months). No reason for onset could be found in 8 (25%) patients, who were classified as primary frozen shoulder; twenty-four (75%) patients were classified as secondary frozen shoulder due to underlying pathologies. The average pre-operative complaint period was 11 months (range: 3-24 months). After arthroscopic examination, manipulation was performed first, followed by arthroscopic capsular release. The range of motion in both shoulders was compared before the procedure and in the last follow-up visit. Constant and Oxford classifications were used to assess functional results, and the results were assessed statistically.

RESULTS

Patient values for passive elevation, abduction, adduction-external rotation, abduction-external rotation, and abduction-internal rotation increased in a statistically significant manner between the preoperative assessment and follow-up evaluation (p<0.01). The average change of 47.97±21.03 units observed in the patients' values obtained in the control measurements against the pre-op Constant scores was determined to be statistically significant (p<0.01). According to the Oxford classification, 29 shoulders were sufficient.

CONCLUSION

Successful results can be obtained with arthroscopic release performed after manipulation in patients with frozen shoulder resistant to conservative treatment. Level of Evidence IV, Case Series.

Patient-reported measures of quality of life and functional capacity in adhesive capsulitis

Objective:

To evaluate patient-reported measures of quality of life and functional capacity in adhesive capsulitis before and after suprascapular nerve block treatment; to analyze the influence of clinical and sociodemographic variables on both the outcome and correlation between the respective instruments.

Method:

A prospective clinical study was performed with adhesive capsulitis patients. Inclusion criteria were clinical diagnosis of adhesive capsulitis and a shoulder imaging test. The WHOQOL-BREF and DASH instruments were administered before and after treatment. A Constant test score of 55 points was used as a cutoff point for discontinuation of treatment. Mean values were compared using paired t-test and Wilcoxon. The Pearson or Spearman coefficients were used for correlation analysis. Multiple linear regression analysis was carried out using variables with p<0.20 as predictors in univariate analysis and WHOQOL domains and DASH as outcomes. The significance level was 5%.

Results:

Forty-three patients were evaluated. The comparison between WHOQOL-BREF and DASH mean values before and after the blocks, p<0.05. DASH correlated negatively with the physical, psychological and environmental WHOQOL-BREF domains. Older patients and those with higher levels of education influenced the improvement in patients' quality of life and functional capacity.

Conclusion:

The improvement of adhesive capsulitis with treatment involves an improvement in quality of life and functional capacity. The greater functional capacity of the shoulder matches a better quality of life for patients. Age and education level are the variables that most influence improvement in quality of life and functional capacity.

Quality of life and functional capacity of patients with adhesive capsulitis: identifying risk factors associated to better outcomes after treatment with nerve blocking

INTRODUCTION

The objectives of this study were to assess the quality of life and functional capacity of adhesive capsulitis patients at the beginning and end of procedure and to identify risk factors associated to better outcomes after treatment with nerve blocking.

METHODS

A prospective cohort study was performed. Inclusion criteria were clinical signs of adhesive capsulitis and disease changes on shoulder imaging exams. The short form of World Health Organization Quality of life and Disabilities of the Arm, Shoulder and Hand questionnaires were administered at the beginning and end of treatment. A score of 55 points or more on the Constant index was used for discontinuation of treatment. We used the Wilcoxon test for paired samples. Multiple regression analysis of Poisson was carried out using exposure variables with p<0.20 in the univariate analysis and the satisfactory quality of life and better functional capability as outcomes. The significance level was 5%.

RESULTS

43 patients were evaluated. For the comparison between medians values at the beginning and end of treatment (physical domain: 46.43-67.86; psychologic domain: 66.67-79.17; social domain: 66.67-75; environment domain: 62.5-68.75; DASH: 64.16-38.33), p was <0.05. Aging (physical/psychologic/DASH), higher educational level (physical/environment/DASH), less severity (only physical) and fewer nerve blocking (only psychologic) were these independent risk factors.

CONCLUSIONS

Quality of life and functional capacity of the patients improve at the end of procedure. Older patients and higher education levels are the risk factors most associated to satisfactory quality of life and better functional capacity after treatment with nerve blocking.

Frozen shoulder - A prospective randomized clinical trial

AIM

To compare the results of arthroscopic capsular release with intra-articular steroid injections in patients of frozen shoulder.

METHODS

Fifty-six patients with frozen shoulder were randomised to one of two treatment groups: Group 1, complete 360 degree arthroscopic capsular release and group 2, intra-articular corticosteroid injection (40 mg methyl prednisolone acetate). Both groups were put on active and passive range of motion exercises following the intervention. The outcome parameters were visual analogue scale (VAS) score for pain, range of motion and Constant score which were measured at baseline, 4, 8, 12, 16 and 20 wk after intervention.

RESULTS

All the parameters improved in both the groups. The mean VAS score improved significantly more in the group 1 as compared to group 2 at 8 wk. This greater improvement was maintained at 20 wk with P value of 0.007 at 8 wk, 0.006 at 12 wk, 0.006 at 16 wk and 0.019 at 20 wk. The Constant score showed a more significant improvement in group 1 compared to group 2 at 4 wk, which was again maintained at 20 wk with P value of 0.01 at 4, 8, 12 and 16 wk. The gain in abduction movement was statistically significantly more in arthroscopy group with P value of 0.001 at 4, 8, 12, 16 wk and 0.005 at 20 wk. The gain in external rotation was statistically significantly more in arthroscopy group with P value of 0.007 at 4 wk, 0.001 at 8, 12, and 16 wk and 0.003 at 20 wk. There was no statistically significant difference in extension and internal rotation between the two groups at any time.

CONCLUSION

Arthroscopic capsular release provides subjective and objective improvement earlier than intra-articular steroid injection.

Adhesive Capsulitis of the Shoulder. Is there Consensus Regarding the Treatment? A Comprehensive Review

Background:

Adhesive capsulitis of the shoulder (ACS) is a common self-limiting condition characterized by disabling pain and restricted movements. Its pathophysiology is poorly understood, clinically it is characterized by stages of pain and stiffness, and finally often patients never recover fully. However, there is no consensus about available methods of treatment for ACS. The aims of this paper are to discuss and develop issues regarding approaches to management in ACS in the stages of it.

Methods:

A review of the literature was performed and guidelines for the treatment of that clinical entity for doctors and health care professionals are provided.

Results:

Anti-inflammatory medications, steroid and/or hyaluronate injections and physiotherapy is the mainstay of conservative management either alone in the first stages or in combination with other treatment modalities in the later stages. Next line of treatment, involving minor to moderate intervention, includes suprascapular nerve block, distension arthrography and manipulation under anaesthesia. In order to avoid complications of “blind intervention”, arthroscopic capsular release is gradually more commonly applied, and in recalcitrant severe cases open release is a useful option.

Conclusion:

Various modalities of conservative management and gradually more surgical release are applied. However, often clinicians choose on personal experience and training rather than on published evidence.

Joint Manipulation Under Anesthesia for Arthrofibrosis After Hallux Valgus Surgery

Arthrofibrosis is a known complication of hallux valgus surgery. Joint manipulation under anesthesia has been studied for adhesive capsulitis of the shoulder; however, a paucity of published data exists on the use of this modality in the foot and ankle. The purpose of the present study was to investigate the outcomes of first metatarsophalangeal joint manipulation for arthrofibrosis that occurred as a complication of bunion surgery. The study population consisted of patients attending a single foot and ankle specialty clinic who were evaluated for arthrofibrosis after bunion surgery. Patients who underwent joint manipulation under anesthesia were asked to complete a research visit in which a clinical examination was performed and the presence and severity of joint pain were assessed. A total of 38 patients (34 females, 4 males, 53 feet), with a mean age of 55.7 ± 11.8 (range 30 to 83) years, agreed to participate. The mean follow-up period was 6.5 ± 3.4 (range 1 to 17) years. The visual analog scale scores improved significantly from baseline to the final follow-up visit (baseline 6.5 ± 1.5, range 2 to 10; final follow-up visit 2.3 ± 1.5, range 0 to 6; p < .001). Furthermore, joint motion had increased significantly (p < .001) for both dorsiflexion and plantarflexion at the final follow-up examination. The final range of motion (dorsiflexion, r = -0.431, p = .002; plantarflexion, r = -0.494, p < .001) correlated highly with patient self-reported pain in the first metatarsophalangeal joint. Our findings suggest that joint manipulation could be a useful modality for increasing first metatarsophalangeal joint mobility and alleviating pain in patients who experience arthrofibrosis after surgical correction of hallux valgus.

Determination of steroid injection sites using lidocaine test in adhesive capsulitis: A prospective randomized clinical trial

BACKGROUND

To validate the usefulness of subacromial bursa lidocaine for determination of the therapeutic steroid injection site in patients with adhesive capsulitis

METHODS

Ninety-two patients with adhesive capsulitis were randomly divided into the LC (lidocaine test) group (n = 46), in which LC injection was performed at the subacromial bursa prior to therapeutic steroid injection, and GH (glenohumeral) group (n = 46), in which the steroid was injected into the GH. Patients in the LC group received steroid injection at the subacromial bursa or GH according to the result of the LC. Both groups underwent the same exercise protocol. Improvement of the shoulder pain was checked at 2 weeks and 3 months postinjection and expressed on an ordinal scale. Passive range of motion was recorded preinjection, and 2 weeks and 3 months postinjection.

RESULTS

Two weeks postinjection, 37 patients expressed "much improved" and 7 patients expressed "slightly improved" pain levels in the LC group, whereas 18 patients each expressed "much improved" and "slightly improved" pain levels in the GH group, which was significantly different (p < 0.01). This difference was maintained 3 months postinjection (p < 0.01). Passive range of motion in all directions improved significantly 3 months postinjection in both the LC and GH groups (p < 0.01). However, there was no significant difference between the LC and GH groups.

CONCLUSIONS

We found that subacromial lidocaine injection prior to steroid injection resulted in better improvement of pain than conventional GH injection for patients with adhesive capsulitis.

Correlation between functional disability and quality of life in patients with adhesive capsulitis

OBJECTIVE:

To determine the correlation between functional disability and quality of life of patients with adhesive capsulitis.

METHODS:

Two instruments (WHOQOL-BREF and DASH) were applied to evaluate the quality of life and functional capacity of patients with adhesive capsulitis. Inclusion criteria were age between 35 and 75 years old and achievement of shoulder imaging. Each domain of the WHOQOL-BREF was correlated with DASH. Pearson's correlation coefficient was used for parametric variables and Spearman's correlation coefficient was used when at least one variable had a non-normal distribution. The level of significance was p <0.05.

RESULTS:

Forty three patients with mean age of 54.7 years old were evaluated. The mean values found in the physical, psychological, social and environmental domains of the WHOQOL-BREF and DASH were 45.3, 63.9, 68.2, 60.2 and 61.6, respectively. A moderate negative correlation was found between DASH and the physical domain of WHOQOL-BREF (r= - 0.583, p<0.001).

CONCLUSION:

The only domain where WHOQOL-BREF correlates with DASH is the physical domain, suggesting that measures to promote the improvement of functional capacity may lead to better quality of life of patients with adhesive capsulitis.

Level of Evidence IV, Prospective Study.

Glenohumeral corticosteroid injections in adhesive capsulitis: a systematic search and review

OBJECTIVE

To assess the literature on outcomes of corticosteroid injections for adhesive capsulitis, and, in particular, image-guided corticosteroid injections. TYPE: Systematic search and review.

LITERATURE SURVEY

The databases used were PubMed (1966-present), EMBASE (1947-present), Web of Science (1900-present), and the Cochrane Central Register of Controlled Trials. Upon reviewing full-text articles of these studies, a total of 25 studies were identified for inclusion. The final yield included 7 prospective studies, 16 randomized trials, and 2 retrospective studies.

METHODOLOGY

This systematic review was formatted by using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Study criteria were limited to clinical trials, prospective studies, and retrospective studies that specifically evaluated intra-articular corticosteroid injections, both alone and in combination with other treatment modalities, for shoulder adhesive capsulitis. We included studies that were not randomized control trials because our review was not a meta-analysis. Data items extracted from each study included the following: study design, study population, mean patient age, duration of study, duration of symptoms, intervention, single or multiple injections, location of injections, control population, follow-up duration, and outcome measurements. A percentage change in outcome measurements was calculated when corresponding data were available. Risk of bias in individual studies was assessed when appropriate.

SYNTHESIS

All the studies involved at least 1 corticosteroid injection intended for placement in the glenohumeral joint, but only 8 studies used image guidance for all injections. Seven of these studies reported statistically significant improvements in range of motion at or before 12 weeks of follow-up. Ninety-two percent of all the studies documented a greater improvement in either visual analog pain scores or range of motion after corticosteroid injections in the first 1-6 weeks compared with the control or comparison group.

CONCLUSIONS

Corticosteroid injections offer rapid pain relief in the short-term (particularly in the first 6 weeks) for adhesive capsulitis. Long-term outcomes seem to be similar to other treatments, including placebo. The added benefit of image-guided corticosteroid injections in improving shoulder outcomes needs further assessment.

Outcomes of Ultrasound-guided Glen Humeral Corticosteroid Injections in Adhesive Capsulitis

Aims

To assess short and longer-term outcomes of ultrasound-guided glenohumeral corticosteroid injections for adhesive capsulitis.

Study Design

A mixed prospective and retrospective study design

Place and Duration of Study

Department of Physical Medicine and Rehabilitation, Spaulding Rehabilitation Hospital, Department of Orthopaedic Surgery, Brigham and Women’s Hospital, between June 2011 and July 2012.

Methodology

Using medical records, we first retrospectively identified patients who had received ultrasound-guided injections of lidocaine and triamcinolone for adhesive capsulitis We then assessed short-term follow-up outcomes (within 3 months of procedure) using medical record review and phone interviews. Longer-term follow-up (at least 3 months from the procedure) outcomes were determined by mailings and phone calls. Average and worst shoulder pain scores were measured on a visual analog scale. Shoulder ROM was measured in forward flexion, isolated abduction, and external rotation.

Results

Patients presented an average of 5.1 (SD=4.1) months after onset of symptoms. Within three months of the injection, 55.9% (95% CI: 39.2%, 72.6%) of patients reported greater than 75% pain relief and 44.1% (95% CI: 27.4%, 60.8%) of patients reported greater than 75% ROM improvement. The percentage of patients who improved increased with increased duration of follow-up. At short-term follow-up (mean=2.1 months, SD=2.7), average pain decreased from 5.6 (SD=2.2) to 3.0 (SD=1.8) (p ≤ .001) and worst pain decreased from 7.8 (SD=1.2) to 4.3 (SD=3.2) (p ≤ .001). At longer-term follow-up (mean =10.4 months, SD=3.7), average pain decreased to 1.9 (SD=1.9) (p ≤ .001) and worst pain decreased to 2.9 (SD=2.3) (p ≤ .001).

Conclusion

A majority of patients had significant pain reduction and functional improvement after an ultrasound guided glenohumeral corticosteroid injection for adhesive capsulitis. Our patients experience the majority of their pain and functional relief within the first three months after an ultrasound-guided corticosteroid injection with continued increase in relief in the longer-term.

Functional results and patient satisfaction after arthroscopic capsular release of idiopathic and post-traumatic stiff shoulder

PURPOSE

The purpose of this prospective study was to compare the functional results and patient satisfaction after arthroscopic shoulder capsular release in patients with idiopathic and posttraumatic stiff shoulder.

METHODS

The study included 50 patients who underwent arthroscopic capsular release after failure of conservative treatment. The etiology of stiffness was either idiopathic (25 patients) or post-traumatic (25 patients). There were 28 women and 22 men with an average age of 49 years (range, 32-70 years). All patients were treated with physical therapy for a mean of six months (range, 3-12 months) before surgery. Range of motion was measured three times: 48 hours after surgery, then one month and six months after surgery.

RESULTS

Constant score showed improvement for both groups of patients in the period of six months after surgery. In the group with idiopathic stiffness the score increased from 36 to 86, while in the group with post-traumatic stiff shoulder the score advanced from 32 to 91. The idiopathic stiff shoulder group had an improved active forward flexion from 90 to 161°, external rotation from 10 to 40°, and internal rotation from L5 to L1. In the post-traumatic stiff shoulder groupthe forward flexion was improved from 95 to 170°, external rotation from 13 to 40° and internal rotation from L4 to L1.

CONCLUSION

There was an improvement of range of motions and patients' satisfaction after arthroscopic shoulder capsular release and manipulation under anesthesia, equally in idiopathic and post-traumatic stiff shoulder, compared to the situation before surgery. Post-traumatic contracture patients expressed higher level of satisfaction with their shoulder function than the idiopathic stiff shoulder patients.

Comparison of manipulation and arthroscopic capsular release for adhesive capsulitis: a systematic review

BACKGROUND

It is currently unclear as to whether there is a difference in the clinical effectiveness of an arthroscopic capsular release compared to a manipulation under anaesthesia (MUA) in patients with recalcitrant idiopathic adhesive capsulitis.

METHODS

A systematic review was performed using computerized keyword searches of MEDLINE, EMBASE, CINAHL, the Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews. Two reviewers independently performed searches and article reduction. Studies that reported outcomes data following either a manipulation under regional or general anaesthesia or an arthroscopic capsular release in patients with idiopathic adhesive capsulitis were included. Data on clinical measures of shoulder range of motion and subjective outcome measures were extracted and summarized.

RESULTS

Twenty-two studies (21 studies provided level IV evidence) including 989 patients were included resulting in a comparison of 9 MUA and 17 capsular release groups. Patients were 60% female with a median age of 52 years old (range, 24-91 years). Median duration of symptoms and follow-up were 9 months (range, 3-50) and 35 months (range, 3-189), respectively. There were minimal differences in the median changes in abduction, flexion, and external rotation range of motion (ROM), and final Constant score between the MUA and capsular release groups.

CONCLUSION

The quality of evidence available is low and the data available demonstrate little benefit for a capsular release instead of, or in addition to, an MUA. A high quality study is required to definitively evaluate the relative benefits of these procedures.
