Meta-Analysis
BACKGROUND
Stiffness is a common reason for suboptimal clinical outcomes after primary total knee arthroplasty (pTKA). There is a lack of consensus regarding its definition, which is often conflated with its histopathologic subcategory-i.e., arthrofibrosis. There is value in refining the definition of acquired idiopathic stiffness in an effort to select for patients with arthrofibrosis. We conducted a systematic review and meta-analysis to establish a consensus definition of acquired idiopathic stiffness, determine its prevalence after pTKA, and identify potential risk factors for its development.
METHODS
MEDLINE, Embase, Cochrane Controlled Register of Trials (CENTRAL), and Scopus databases were searched from 2002 to 2017. Studies that included patients with stiffness after pTKA were screened with strict inclusion and exclusion criteria to isolate the subset of patients with acquired idiopathic stiffness unrelated to known extrinsic or surgical causes. Three authors independently assessed study eligibility and risk of bias and collected data. Outcomes of interest were then analyzed according to age, sex, and body mass index (BMI).
RESULTS
In the 35 included studies (48,873 pTKAs), the mean patient age was 66 years. In 63% of the studies, stiffness was defined as a range of motion of <90° or a flexion contracture of >5° at 6 to 12 weeks postoperatively. The prevalence of acquired idiopathic stiffness after pTKA was 4%, and this did not differ according to age (4%, I = 95%, among patients <65 years old and 5%, I = 96%, among those ≥65 years old; p = 0.238). The prevalence of acquired idiopathic stiffness was significantly lower in males (1%, I = 85%) than females (3%, I = 95%) (p < 0.0001) as well as in patients with a BMI of <30 kg/m (2%, I = 94%) compared with those with a BMI of ≥30 kg/m (5%, I = 97%) (p = 0.027).
CONCLUSIONS
Contemporary literature supports the following definition for acquired idiopathic stiffness: a range of motion of <90° persisting for >12 weeks after pTKA in patients in the absence of complicating factors including preexisting stiffness. The mean prevalence of acquired idiopathic stiffness after pTKA was 4%; females and obese patients were at increased risk.

The clinical treatment of joint contracture due to immobilization remains difficult. The pathological changes of muscle tissue caused by immobilization-induced joint contracture include disuse skeletal muscle atrophy and skeletal muscle tissue fibrosis. The proteolytic pathways involved in disuse muscle atrophy include the ubiquitin-proteasome-dependent pathway, caspase system pathway, matrix metalloproteinase pathway, Ca-dependent pathway and autophagy-lysosomal pathway. The important biological processes involved in skeletal muscle fibrosis include intermuscular connective tissue thickening caused by transforming growth factor-β1 and an anaerobic environment within the skeletal muscle leading to the induction of hypoxia-inducible factor-1α. This article reviews the progress made in understanding the pathological processes involved in immobilization-induced muscle contracture and the currently available treatments. Understanding the mechanisms involved in immobilization-induced contracture of muscle tissue should facilitate the development of more effective treatment measures for the different mechanisms in the future.

Camptodactyly is a pediatric hand condition, the treatment of which remains controversial. The authors' aim was to improve patient care through clarifying the definition of camptodactyly and indications for surgical and/or conservative management, summarizing outcomes, and defining risks. A systematic review was conducted of articles in all languages on outcomes following surgical and/or conservative management of idiopathic camptodactyly in children using MEDLINE (Medical Literature Analysis and Retrieval System Online), PubMed, EMBASE (Excerpta Medica database), AMED (Allied and Complementary Medicine), and CINAHL (Cumulative Index of Nursing and Allied Health Literature) (until January 2017). The primary outcome was posttreatment flexion contracture, and the secondary outcomes were indications for surgery, complications, and patient satisfaction. Database searching generated 16 final articles, with 7 case series and 9 retrospective cohort studies. There was a lack of consistency on the definition of camptodactyly and in outcome reporting. All 16 studies received a "Weak" global rating and demonstrated low-quality evidence, suggesting that treatment of camptodactyly with operative or nonoperative measures reduces the degree of flexion contracture in most patients (from pretreatment averages of 20°-85° to posttreatment averages of 5°-37°). There was general agreement that surgery should be reserved for contracture >30° or failure to respond to conservative management. Surgery generally led to more complications compared with conservative management. Only one study reported on functional limitations, and another reported on patient-reported outcomes. Current evidence of the effectiveness of camptodactyly treatment in addressing both joint-specific deformity and patient-perceived function and appearance is insufficient to guide patient care. Future research may consider the development of decision aids to guide patients and families through selecting management strategies and to promote shared decision making.

The Journal of Bone and Joint Surgery.... Feb 2019The objective of this study was to analyze the literature regarding the diagnosis, pathogenesis, and prevalence of gluteal fibrosis (GF) and the outcomes of treatment.
BACKGROUND
The objective of this study was to analyze the literature regarding the diagnosis, pathogenesis, and prevalence of gluteal fibrosis (GF) and the outcomes of treatment.
METHODS
We searched PubMed, Embase, and Cochrane literature databases, from database inception to December 15, 2016. We used the following search terms including variants: "contracture," "fibrosis," "injections," "injections, adverse reactions,' "gluteal," and "hip." All titles and abstracts of potentially relevant studies were scanned to determine whether the subject matter was potentially related to GF, using predefined inclusion and exclusion criteria. If the abstract had subject matter involving GF, the paper was selected for review if full text was available. Only papers including ≥10 subjects who underwent surgical treatment were included in the systematic analysis. Data abstracted included the number of patients, patient age and sex, the type of surgical treatment, the method of outcome measurement, and outcomes and complications.
RESULTS
The literature search yielded 2,512 titles. Of these, 82 had a focus on GF, with 50 papers meeting the inclusion criteria. Of the 50 papers reviewed, 18 addressed surgical outcomes. The surgical techniques in these papers included open, minimally invasive, and arthroscopic release and radiofrequency ablation. Of 3,733 operatively treated patients in 6 reports who were evaluated on the basis of the criteria of Liu et al., 83% were found to have excellent results. Few papers focused on the incidence, prevalence, and natural history of GF, precluding quantitative synthesis of the evidence in these domains.
CONCLUSIONS
This study provided a systematic review of surgical outcomes and a summary of what has been reported on the prevalence, diagnosis, prognosis, and pathogenesis of GF. Although GF has been reported throughout the world, it requires further study to determine the exact etiology, pathogenesis, and appropriate treatment. Surgical outcomes appear satisfactory.

Review
BACKGROUND/OBJECTIVE
Fixed flexion deformity of the proximal interphalangeal joint can commonly occur following a traumatic injury impacting on hand function and occupational performance. Numerous interventions have been proposed for fixed flexion deformity resolution. This paper investigates the efficacy of static or dynamic orthoses in reducing fixed flexion deformity contracture following traumatic proximal interphalangeal joint injury.
METHODS
A multi-database search of three databases (CINAHL, EMBASE, MEDLINE) was conducted. Data extracted for each study were design, patient descriptions, degree of fixed flexion deformity pre- and post-orthoses, and prescribed interventions and exercise programmes.
RESULTS
The search yielded 643 studies, of which eight met the inclusion criteria. Studies used heterogeneous methodologies investigating various orthotic interventions. Meta-analysis or pooling of results was not possible. Dissimilar orthotic wear regimes were noted in all studies and an alternative clinical significance outcome was found.
CONCLUSION
More research is required to support clinical reasoning in orthotic choice for fixed flexion deformity of the proximal interphalangeal joint post-traumatic injury.

Review
AIMS
Dupuytren's contracture is a benign, myoproliferative condition affecting the palmar fascia that results in progressive contractures of the fingers. Despite increased knowledge of the cellular and connective tissue changes involved, neither a cure nor an optimum form of treatment exists. The aim of this systematic review was to summarize the best available evidence on the management of this condition.
MATERIALS AND METHODS
A comprehensive database search for randomized controlled trials (RCTs) was performed until August 2017. We studied RCTs comparing open fasciectomy with percutaneous needle aponeurotomy (PNA), collagenase clostridium histolyticum (CCH) with placebo, and CCH with PNA, in addition to adjuvant treatments aiming to improve the outcome of open fasciectomy. A total of 20 studies, involving 1584 patients, were included.
RESULTS
PNA tended to provide higher patient satisfaction with fewer adverse events, but had a higher rate of recurrence compared with limited fasciectomy. Although efficacious, treatment with CCH had notable recurrence rates and a high rate of transient adverse events. Recent comparative studies have shown no difference in clinical outcome between patients treated with PNA and those treated with CCH.
CONCLUSION
Currently there remains limited evidence to guide the management of patients with Dupuytren's contracture. Cite this article: Bone Joint J 2018;100-B:1138-45.

BACKGROUND
Most brachial plexus birth injuries (BPBIs) are caused by traction on the brachial plexus during a difficult delivery. Fortunately, the possibility of complete recovery from such an incident is relatively high, with only 10% to 30% of patients having prolonged and persistent disability. These patients have muscle imbalances and co-contractions typically localized around the shoulder and elbow. These imbalances and co-contractures cause abnormal motor performances and bone/joint deformities. Typically, physical/occupational therapies are the conventional therapeutic modalities but are often times inadequate. Botulinum toxin A (BTX-A) injections into targeted muscles have been used to combat the muscular imbalances and co-contractions.
METHODS
With compliance to PRISMA guidelines, a systematic review was performed to identify studies published between 2000 and 2017 that used BTX-A to treat neonatal brachial plexus palsies.
RESULTS
Ten studies were included, involving 325 patients. Three groups of indications for the use of BTX-A were identified: (1) internal rotation/adduction contracture of the shoulder; (2) elbow flexion lag/elbow extension lag; and (3) forearm pronation contracture.
CONCLUSIONS
The included studies show an overall beneficial effect of BTX-A in treating co-contractures seen in patients with BPBI. Specifically, BTX-A is shown to reduce internal rotation/adduction contractures of the shoulder, elbow flexion/extension contractures, and forearm pronation contractures. These beneficial effects are blunted when used in older patients. Nevertheless, BTX-A is a useful treatment for BPBIs with a relatively low-risk profile.

Review
The loss of range of motion (ROM) in the upper extremities can interfere with activities of daily living (ADL) and, therefore, many interventions focus on improving impaired ROM. The question, however, is what joint angles are needed to naturally perform ADL. The present review aimed to compile and synthesize data from literature on shoulder and elbow angles that unimpaired participants used when performing ADL tasks. A search was conducted in PubMed, Cochrane, Scopus, CINAHL, and PEDro. Studies were eligible when shoulder (flexion, extension, abduction, adduction) and/or elbow (flexion, extension) angles were measured in unimpaired participants who were naturally performing ADL tasks, and angles were provided per task. Thirty-six studies involving a total of 66 ADL tasks were included. Results demonstrated that unimpaired participants used up to full elbow flexion (150°) in personal care, eating, and drinking tasks. For shoulder flexion and abduction approximately 130° was necessary. Specific ADL tasks were measured often, however, almost never for tasks such as dressing. The synthesized information can be used to interpret impairments on the individual level and to establish rehabilitation goals in terms of function and prevention of secondary conditions due to excessive use of compensatory movements.

Review
BACKGROUND
Skeletal muscle spasticity is a major physical complication resulting from traumatic brain injury (TBI), which can lead to muscle contracture, joint stiffness, reduced range of movement, broken skin and pain. Treatments for spasticity include a range of pharmacological and non-pharmacological interventions, often used in combination. Management of spasticity following TBI varies from other clinical populations because of the added complexity of behavioural and cognitive issues associated with TBI.
OBJECTIVES
To assess the effects of interventions for managing skeletal muscle spasticity in people with TBI.
SEARCH METHODS
In June 2017, we searched key databases including the Cochrane Injuries Group Specialised Register, CENTRAL, MEDLINE (Ovid), Embase (Ovid) and others, in addition to clinical trials registries and the reference lists of included studies.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) and cross-over RCTs evaluating any intervention for the management of spasticity in TBI. Only studies where at least 50% of participants had a TBI (or for whom separate data for participants with TBI were available) were included. The primary outcomes were spasticity and adverse effects. Secondary outcome measures were classified according to the World Health Organization International Classification of Functioning, Disability and Health including body functions (sensory, pain, neuromusculoskeletal and movement-related functions) and activities and participation (general tasks and demands; mobility; self-care; domestic life; major life areas; community, social and civic life).
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane. Data were synthesised narratively; meta-analysis was precluded due to the paucity and heterogeneity of data.
MAIN RESULTS
We included nine studies in this review which involved 134 participants with TBI. Only five studies reported between-group differences, yielding outcome data for 105 participants with TBI. These five studies assessed the effects of a range of pharmacological (baclofen, botulinum toxin A) and non-pharmacological (casting, physiotherapy, splints, tilt table standing and electrical stimulation) interventions, often in combination. The studies which tested the effect of baclofen and tizanidine did not report their results adequately. Where outcome data were available, spasticity and adverse events were reported, in addition to some secondary outcome measures.Of the five studies with results, three were funded by governments, charities or health services and two were funded by a pharmaceutical or medical technology company. The four studies without useable results were funded by pharmaceutical or medical technology companies.It was difficult to draw conclusions about the effectiveness of these interventions due to poor reporting, small study size and the fact that participants with TBI were usually only a proportion of the overall total. Meta-analysis was not feasible due to the paucity of data and heterogeneity of interventions and comparator groups. Some studies concluded that the intervention they tested had beneficial effects on spasticity, and others found no difference between certain treatments. The most common adverse event was minor skin damage in people who received casting. We believe it would be misleading to provide any further description of study results given the quality of the evidence was very low for all outcomes.
AUTHORS' CONCLUSIONS
The very low quality and limited amount of evidence about the management of spasticity in people with TBI means that we are uncertain about the effectiveness or harms of these interventions. Well-designed and adequately powered studies using functional outcome measures to test the interventions used in clinical practice are needed.

BACKGROUND
As one of the most common musculoskeletal complications following trauma, elbow contracture is a frequent source of disabled daily activities. Conventional interventions are inadequate to provide favorable outcome. The static progressive orthoses are getting popular in the treatment of this problem.
OBJECTIVE
The purpose of this review was to assess the effectiveness of static progressive orthoses for elbow contracture.
METHODS
Literatures when written in English published during 1 January 1997 and 31 January 2017 were searched in the following databases: Web of Science, Cochrane Library, PubMed, and EBSCOhost. Articles are quality-assessed by two assessors, each article was summarized in evidence tables, and a narrative synthesis was also performed.
RESULTS
Ten clinical trials were included. The study design and outcome measures used varied. Significant immediate improvement in the range of motion was reported by all studies, and those effects were still significant at follow-up. No significant difference was shown between static progressive and dynamic orthoses for elbow contracture in one randomized control trial.
CONCLUSIONS
Current low-quality evidence suggested that static progressive orthoses provided assistance for elbow contracture through improving range of motion. Further research is recommended using high-quality randomized controlled trials.
