A total of 92 patients with symptoms for over six months due to subacromial impingement of the shoulder, who were being treated with physiotherapy, were included in this study. While continuing with physiotherapy they waited a further six months for surgery. They were divided into three groups based on the following four clinical and radiological criteria: temporary benefit following steroid injection, pain in the mid-arc of abduction, a consistently positive Hawkins test and radiological evidence of impingement. Group A fulfilled all four criteria, group B three criteria and group C two criteria. A total of nine patients improved while waiting for surgery and were excluded, leaving 83 who underwent arthroscopic subacromial decompression (SAD). The new Oxford shoulder score was recorded pre-operatively and at three and 12 months post-operatively.

A total of 51 patients (group A) had a significant improvement in the mean shoulder score from 18 (13 to 22) pre-operatively to 38 (35 to 42) at three months (p < 0.001). The mean score in this group was significantly better than in group B (21 patients) and C (11 patients) at this time. At one year patients in all groups showed improvement in scores, but patients in group A had a higher mean score (p = 0.01). At one year patients in groups A and B did better than those in group C (p = 0.01).

Arthroscopic SAD is a beneficial intervention in selected patients. The four criteria could help identify patients in whom it is likely to be most effective.

The global economy has been facing a financial crisis. Healthcare costs are spiraling, and there is a projected £30 billion health funding gap by 2020 in the UK.¹ This has prompted a drive for efficiency in healthcare provision in the UK, and in 2012, the Health and Social Care Act was introduced, heralding a fundamental change to the structure of the National Health Service, especially in the way that healthcare is funded in England.²

What is happening in the UK is a reflection of a global problem. Rationing of healthcare is a topic of much discussion; as unless spending is capped, providing healthcare will become unsustainable. Who decides how money is spent, and which services should be rationed?

In this article we aim to discuss the impact that rationing may have on orthopaedic surgery, and we will discuss our own experiences of attempts to ration local services.³ We also seek to inform and educate the general orthopaedic community on this topic.

The October 2015 Research Roundup360 looks at: Wasted implants; Biofilms revisited; Peri-operative anticoagulation not required in atrial fibrillation; Determinants in outcome following orthopaedic surgery; Patient ‘activation’ and outcomes; Neuroplasticity and nerve repair; KOOS Score in predicting injury?

The reported prevalence of an asymptomatic slip of the contralateral hip in patients operated on for unilateral slipped capital femoral epiphysis (SCFE) is as high as 40%. Based on a population-based cohort of 2072 healthy adolescents (58% women) we report on radiological and clinical findings suggestive of a possible previous SCFE. Common threshold values for Southwick’s lateral head–shaft angle (≥ 13°) and Murray’s tilt index (≥ 1.35) were used. New reference intervals for these measurements at skeletal maturity are also presented.

At follow-up the mean age of the patients was 18.6 years (17.2 to 20.1). All answered two questionnaires, had a clinical examination and two hip radiographs.

There was an association between a high head–shaft angle and clinical findings associated with SCFE, such as reduced internal rotation and increased external rotation. Also, 6.6% of the cohort had Southwick’s lateral head–shaft angle ≥ 13°, suggestive of a possible slip. Murray’s tilt index ≥ 1.35 was demonstrated in 13.1% of the cohort, predominantly in men, in whom this finding was associated with other radiological findings such as pistol-grip deformity or focal prominence of the femoral neck, but no clinical findings suggestive of SCFE.

This study indicates that 6.6% of young adults have radiological findings consistent with a prior SCFE, which seems to be more common than previously reported.

The aim of this study was to examine the functional outcome at ten years following lateral closing wedge high tibial osteotomy for medial compartment osteoarthritis of the knee and to define pre-operative predictors of survival and determinants of functional outcome.

164 consecutive patients underwent high tibial osteotomy between 2000 and 2002. A total of 100 patients (100 knees) met the inclusion criteria and 95 were available for review at ten years. Data were collected prospectively and included patient demographics, surgical details, long leg alignment radiographs, Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and Knee Society scores (KSS) pre-operatively and at five and ten years follow-up.

At ten years, 21 patients had been revised at a mean of five years. Overall Kaplan–Meier survival was 87% (95% confidence interval (CI) 81 to 94) and 79% (95% CI 71 to 87) at five and ten years, respectively. When compared with unrevised patients, those who had been revised had significantly lower mean pre-operative WOMAC Scores (47 (21 to 85) vs 65 (32 to 99), p < 0.001), higher mean age (54 yrs (42 to 61) vs 49 yrs (26 to 66), p = 0.006) and a higher mean BMI (30.2; 25 to 39 vs 27.9; 21 to 36, p = 0.005). Each were found to be risk factors for revision, with hazard ratios of 10.7 (95% CI 4 to 28.6; pre-operative WOMAC < 45), 6.5 (95% CI 2.4 to 17.7; age > 55) and 3.0 (95%CI 1.2 to 7.6; BMI > 30). Survival of patients with pre-operative WOMAC > 45, age < 55 and BMI < 30 was 97% at five and ten years. WOMAC and KSS in surviving patients improved significantly between pre-operative (mean 61; 32 to 99) and five (mean 88; 35 to 100, p = 0.001) and ten years (mean 84; 38 to 100, p = 0.001). Older patients had better functional outcomes overall, despite their higher revision rate.

This study has shown that improved survival is associated with age < 55 years, pre-operative WOMAC scores > 45 and, a BMI < 30. In patients over 55 years of age with adequate pre-operative functional scores, survival can be good and functional outcomes can be significantly better than their younger counterparts. We recommend the routine use of pre-operative functional outcome scores to guide decision-making when considering suitability for high tibial osteotomy.

Aims

A pragmatic multicentre randomised controlled trial (PROFHER) was conducted in United Kingdom National Health Service (NHS) hospitals to evaluate the clinical effectiveness and cost effectiveness of surgery compared with non-surgical treatment for displaced fractures of the proximal humerus involving the surgical neck in adults.

The August 2014 Spine Roundup³⁶⁰ looks at: rhBMP complicates cervical spine surgery; posterior longitudinal ligament revisited; thoracolumbar posterior instrumentation without fusion in burst fractures; risk modelling for VTE events in spinal surgery; the consequences of dural tears in microdiscectomy; trends in revision spinal surgery; radiofrequency denervation likely effective in facet joint pain and hooks optimally biomechanically transition posterior instrumentation.

Bariatric surgery has been advocated as a means of reducing body mass index (BMI) and the risks associated with total knee arthroplasty (TKA). However, this has not been proved clinically. In order to determine the impact of bariatric surgery on the outcome of TKA, we identified a cohort of 91 TKAs that were performed in patients who had undergone bariatric surgery (bariatric cohort). These were matched with two separate cohorts of patients who had not undergone bariatric surgery. One was matched 1:1 with those with a higher pre-bariatric BMI (high BMI group), and the other was matched 1:2 based on those with a lower pre-TKA BMI (low BMI group).

In the bariatric group, the mean BMI before bariatric surgery was 51.1 kg/m² (37 to 72), which improved to 37.3 kg/m² (24 to 59) at the time of TKA. Patients in the bariatric group had a higher risk of, and worse survival free of, re-operation (hazard ratio (HR) 2.6; 95% confidence interval (CI) 1.2 to 6.2; p = 0.02) compared with the high BMI group. Furthermore, the bariatric group had a higher risk of, and worse survival free of re-operation (HR 2.4; 95% CI 1.2 to 3.3; p = 0.2) and revision (HR 2.2; 95% CI 1.1 to 6.5; p = 0.04) compared with the low BMI group.

While bariatric surgery reduced the BMI in our patients, more analysis is needed before recommending bariatric surgery before TKA in obese patients.

Objectives

Local corticosteroid infiltration is a common practice of treatment for lateral epicondylitis. In recent studies no statistically significant or clinically relevant results in favour of corticosteroid injections were found. The injection of autologous blood has been reported to be effective for both intermediate and long-term outcomes. It is hypothesised that blood contains growth factors, which induce the healing cascade.

Objectives

A patient-centred approach, usually achieved through shared decision making, has the potential to help improve decision making around knee arthroplasty surgery. However, such an approach requires an understanding of the factors involved in patient decision making. This review’s objective is to systematically examine the qualitative literature surrounding patients’ decision making in knee arthroplasty.

The August 2012 Knee Roundup³⁶⁰ looks at: meniscal defects and a polyurethane scaffold; which is best between a single or double bundle; OA of the knee; how to resolve anterior knee pain; whether yoga can be bad for your menisci; metal ions in the serum; whether ACI is any good; the ACL; whether hyaluronic acid delays collagen degradation; and hyaluronan and patellar tendinopathy.

The incidence of acute and chronic conditions of the tendo Achillis appear to be increasing. Causation is multifactorial but the role of inherited genetic elements and the influence of environmental factors altering gene expression are increasingly being recognised. Certain individuals’ tendons carry specific variations of genetic sequence that may make them more susceptible to injury. Alterations in the structure or relative amounts of the components of tendon and fine control of activity within the extracellular matrix affect the response of the tendon to loading with failure in certain cases.

This review summarises present knowledge of the influence of genetic patterns on the pathology of the tendo Achillis, with a focus on the possible biological mechanisms by which genetic factors are involved in the aetiology of tendon pathology. Finally, we assess potential future developments with both the opportunities and risks that they may carry.

Adolescent idiopathic scoliosis affects about 3% of children. Non-operative measures are aimed at altering the natural history to maintain the size of the curve below 40° at skeletal maturity. The application of braces to treat spinal deformity pre-dates the era of evidence-based medicine, and there is a paucity of irrefutable prospective evidence in the literature to support their use and their effectiveness has been questioned.

This review considers this evidence. The weight of the evidence is in favour of bracing over observation. The most recent literature has moved away from addressing this question, and instead focuses on developments in the design of braces and ways to improve compliance.

This study compared the clinical outcomes following mini-open rotator cuff repair (MORCR) between early mobilisation and usual care, involving initial immobilisation. In total, 189 patients with radiologically-confirmed full-thickness rotator cuff tears underwent MORCR and were randomised to either early mobilisation (n = 97) or standard rehabilitation (n = 92) groups. Patients were assessed at six weeks and three, six, 12 and 24 months post-operatively. Six-week range of movement comparisons demonstrated significantly increased abduction (p = 0.002) and scapular plane elevation (p = 0.006) in the early mobilisation group, an effect which was not detectable at three months (p > 0.51) or afterwards. At 24 months post-operatively, patients who performed pain-free, early active mobilisation for activities of daily living showed no difference in clinical outcomes from patients immobilised for six weeks following MORCR. We suggest that the choice of rehabilitation regime following MORCR may be left to the discretion of the patient and the treating surgeon.

We explored the outcome of staged bilateral total knee replacement (TKR) for symmetrical degenerative joint disease and deformity in terms of patient expectations, functional outcome and satisfaction. From 2009 to 2011, 70 consecutive patients (41 female) with a mean age of 71.7 years (43 to 89) underwent 140 staged bilateral TKRs at our institution, with a mean time between operations of 7.8 months (2 to 25). Patients were assessed pre-operatively and at six and 12 months post-operatively using the Short Form-12, Oxford knee score (OKS), expectation questionnaire and satisfaction score. The pre-operative OKS was significantly worse before the first TKR (TKR1), but displayed significantly greater improvement than that observed after the second TKR (TKR2). Expectation level increased from TKR1 to TKR2 in 17% and decreased in 20%. Expectations of pain relief and stair-climbing were less before TKR2; in contrast, expectations of sporting and social activities were greater. Decreased expectations of TKR2 were significantly associated with younger age and high expectations before TKR1. Patient satisfaction was high for both TKR1 (93%) and TKR2 (87%) but did not correlate significantly within individuals. We concluded that satisfaction with one TKR does not necessarily translate to satisfaction following the second.

This study compares the cost-effectiveness of treating dorsally displaced distal radial fractures with a volar locking plate and percutaneous fixation. It was performed from the perspective of the National Health Service (NHS) using data from a single-centre randomised controlled trial. In total 130 patients (18 to 73 years of age) with a dorsally displaced distal radial fracture were randomised to treatment with either a volar locking plate (n = 66) or percutaneous fixation (n = 64). The methodology was according to National Institute for Health and Care Excellence guidance for technology appraisals. .

There were no significant differences in quality of life scores between groups at any time point in the study. Both groups returned to baseline one year post-operatively.

NHS costs for the plate group were significantly higher (p < 0.001, 95% confidence interval 497 to 930). For an additional £713, fixation with a volar locking plate offered 0.0178 additional quality-adjusted life years in the year after surgery. The incremental cost-effectiveness ratio (ICER) for plate fixation relative to percutaneous fixation at list price was £40 068. When adjusting the prices of the implants for a 20% hospital discount, the ICER was £31 898. Patients who underwent plate fixation did not return to work earlier.

We found no evidence to support the cost-effectiveness, from the perspective of the NHS, of fixation using a volar locking plate over percutaneous fixation for the operative treatment of a dorsally displaced radial fracture.
