Introduction

High flexion knee arthroplasties have been designed to allow up to 155 degrees flexion and enable high flexion activities such as kneeling and squatting. To date randomised controlled trials have shown no difference in range of movement (ROM) between high flexion and standard designs.

Background

Adhesive capsulitis (frozen shoulder) is a debilitating condition affecting 2–5% of the adult population. Its aetiology is still unclear and there is no consensus on the most effective treatment. The aim of this retrospective study was to investigate the mid-term functional outcome of one specific treatment protocol.

Introduction

The purpose of this study was to establish whether men and women with a fragility hip fracture were equally investigated and treated for osteoporosis.

Large and massive rotator cuff tears can cause persistent pain and significant disability. These tears are often chronic with substantial degeneration of the involved tendons. Surgical treatment is challenging and the functional outcome after repair less predictable then for smaller tears. The aim of this study was to determine the functional outcome and rate of re-rupture after mini-open repair of symptomatic large and massive rotator cuff tears using a modified two-row technique.

Twenty-four patients, who were operated on under the care of a single surgeon between 2003 and 2006, were included in this study. Patients were assessed prospectively before and at a mean of 27 months after surgery using Constant Score and Oxford Shoulder Score. This assessment was carried out by an independent physiotherapist specialising in shoulder rehabilitation. At follow-up an ultrasound was carried out by a musculoskeletal radiographer to determine the integrity of the rotator cuff repair. Patient satisfaction was assessed using a simple questionnaire.

The mean Constant Score improved significantly from 36 preoperatively to 68 postoperatively (p< 0.0001), the mean Oxford Shoulder Score from 39 to 20 (p< 0.0001). Four patients (16.7%) had a re-rupture diagnosed by ultrasound. 87.5% of patients were satisfied with the outcome of their surgery. Tear size and repair integrity did not significantly influence functional outcome. 87.5% of patients were satisfied or very satisfied with the outcome of their surgery.

This study shows that the two-row repair of large and massive rotator cuff tears using a mini-open approach is an effective method of repair with a comparatively low re-rupture rate. It significantly improves the functional outcome and leads to a very high patient satisfaction. We conclude that these results justify repair of large to massive rotator cuff tears when possible, irrespective of chronicity of symptoms.

Background: Functional outcome and patient satisfaction after total knee arthroplasty can be variable. Up to 20% of patients have been reported to not be entirely happy with their knee replacement. Psychological factors, in particular illness perception – a patient’s beliefs about their illness – have been found to predict recovery from a range of conditions. Few studies have examined their impact within the orthopaedic context.

Aim: The aim of this study was to investigate the impact of psychological factors, including illness perception, anxiety and depression, on postoperative recovery and functional outcome after total knee arthroplasty.

Patients and Methods: 100 patients from two centres, who underwent a primary total knee arthroplasty for osteoarthritis between 2004 and 2006, took part in this prospective cohort study.

Before surgery patients were asked to complete a psychological questionnaire consisting of Revised Illness Perception Questionnaire (IPQ-r), Hospital Anxiety and Depression Scale (HADS) and Recovery Locus of Control (RLOC). Knee function was assessed preoperatively, at six weeks and one year using Oxford Knee Score (OKS) and range of motion (ROM).

Results: The mean OKS improved significantly at six weeks and further at one year. The mean ROM showed little change in the first six weeks, but was significantly improved at the one-year follow-up.

The psychological factors Consequences, Illness Coherence, Emotional Representation and HADS Anxiety showed a statistically significant correlation with the OKS at six weeks, the factors Consequences and HADS Anxiety and HADS Depression with the OKS at one year. We found no correlation with range of motion at six weeks, but ROM at one year was statistically significantly correlated with the factors Consequences and HADS Depression.

This indicates that patients who believed that their illness had less impact on their personal lives and patients with lower scores on the anxiety and depression scale showed a lower OKS and higher ROM at one year, indicating a better functional outcome.

Hierarchical regression analysis showed that, after controlling for demographics and baseline scores, the factor consequences explained 7% of the variance in ROM at one year. HADS Anxiety and Depression had a significant impact on OKS and accounted for 13.7% of the variance of OKS at one year.

Discussion: Recovery from TKA surgery can be difficult to predict. This study showed that functional outcome can be significantly influenced by psychological factors. These should be taken into account when considering patients for TKA surgery. Improving patient education, looking at home environment and social network as well as addressing anxiety and depression may help to improve overall outcome after TKA surgery.

MRSA infections are a current concern in the elderly orthopaedic patient, with colonisation rates of between 417% reported in these patient groups. In our institution there has been concern regarding MRSA surgical site infection and cross contamination of elective and emergency patients. This prompted the unit to consider a screening programme to identify MRSA carriers. We undertook the following project to assess the feasibility and effectiveness of implementing such a screening programme.

The aim was to to ascertain the incidence of colonisation with MRSA, rate of wound infection and associated risk factors in patients admitted with a fractured proximal femur.

This was a prospective, blinded case series of 100 consecutive patients admitted to the trauma ward with a fractured proximal femur. Three swabs (axilla, nasal and perineum) were taken within 24 hours of admission. Data from each patient was collated and each patient was followed until discharge to assess for surgical site infection.

The age range was 60–97 years. 26% were admitted from institutional care. Four patients were colonised with MRSA on admission. An association was seen between patients colonised on admission and long term or recent residence in institutional care. One of these patients went on to develop colonisation of the surgical wound however this did not lead to surgical site infection and the patient was successfully treated with MRSA eradication therapy only. In these 4 patients all wounds healed satisfactorily with no evidence of infection.

While MRSA continues to be a growing concern in the press we found that rates of colonisation and subsequent infection were not high. There were no documented cases of MRSA wound infection in colonised individuals. Given the cost to detect these low levels of colonisation we do not feel that a screening regime would be cost effective or justified.

Background: In recent years an increased trend in MRSA infection has been seen in hospitals and the community, with colonisation rates of between 4 – 17% reported in these patient groups. There is also an association between carriage of Staph. Aureus and staphylococcal surgical wound infection.

In our institution there has been concern regarding MRSA surgical site infection and possible cross contamination of elective and emergency patients. There would be implications for implant related infections if this were to occur. This had prompted the unit to consider adopting a screening programme to identify and treat MRSA carriers. This would aim to minimise risk of post operative infection and cross infection. As little was actually known about the MRSA colonisation rates of admissions to our hospital we undertook the following project to assess the feasibility and effectiveness of implementing such a screening programme.

Aim: To ascertain the incidence of colonisation with MRSA, rate of wound infection and the associated risk factors in patients admitted to the trauma ward with a fractured neck of femur.

Method: A prospective, blinded case series of 100 consecutive patients admitted to the trauma ward with a fractured neck of femur. Three swabs (axilla, nasal and perineum) were taken within 24 hours of admission. Data from each patient was collected to ascertain the presence of risk factors linked to MRSA colonisation and each patient was followed until discharged to assess for surgical site infection.

Results: 304 swabs were taken from 100 patients. Age range 60–97. 26% admitted from institutionalised care and 74% admitted from their own home. Four patients were colonised with MRSA on admission (2 nasal, 2 perineal). An association was seen between patients colonised on admission and long term or recent residence in institutionalised care. One of these patients went on to develop colonisation of the surgical wound however this did not lead to surgical site infection and the patient was successfully treated with MRSA eradication therapy only. In these 4 patients all wounds healed satisfactorily with no evidence of infection.

There were three superficial surgical site infections postoperatively, all in individuals who were clear on their admission screening. Of these two were due to MRSA and one was due to MSSA. There were no cases of deep infection requiring further surgery.

Conclusion:While MRSA continues to be a growing concern we found that, in our hospital, rates of MRSA colonisation and subsequent infection were not high. There were no documented cases of MRSA wound infection in colonised individuals. Given the cost involved in swabbing all patients to detect these low levels of colonisation we do not feel that an expensive screening regimen would be cost effective or justified in our institution.

Introduction: Fragility fractures are taking up an increasing amount of resources within Trauma departments. Women have a 1 in 3, men a 1 in 12 lifetime risk of sustaining an osteoporotic fracture with a previous fracture being the strongest independent predictor of sustaining a further fragility fracture, often within one year. Secondary prevention is therefore particularly important. Many guidelines give advice on secondary prevention in women, but very few mention men even though men have a higher morbidity and mortality after hip fractures.

Methods: A retrospective review was carried out including 91 patients (48 females, 43 males) who were admitted with a fragility hip fracture between March 2003 and April 2004. Data about age, sex, investigations and medication were collected from the case notes, GP surgeries and the bone densitometry database. Investigations and treatment were compared with current guidelines (SIGN 2003, NICE 2005). Data was analysed using SPSS Version 13.0.

Results: 33% of women and only 8% of men < 75 years of age were investigated for osteoporosis (DEXA scan) following their hip fracture (Fishers Exact Test, p = 0.32). In patients ≥ 75 years 25% of women and only 6% of men were treated with bisphosphonates (χ² = 4.18, p < 0.05). There was also a statistically significant difference in overall treatment including bisphosphonates and calcium/vitamin D between the sexes (χ² = 6.81, p < 0.05).

Discussion: This study shows that there is a great need for improvement in secondary prevention of osteoporotic fragility fractures in both sexes, but men are far less likely to receive investigations and treatment than women. It is therefore essential to include recommendations for men in future guidelines and to increase awareness of male osteoporosis. Orthopaedic surgeons should take responsibility for initiating the process of secondary prevention.
