Enhanced recovery programmes have improved outcomes following elective arthroplasty surgery. Most studies assess whole advanced recovery programmes. There are few studies assessing the role of patient education. We therefore assessed our outcomes.

As part of our enhanced recovery programme at Wrexham Maelor Hospital, all patients are offered the chance to attend ‘joint school’, a preoperative education class. Not all patients attend these sessions allowing comparison of outcomes in these two groups using our prospectively collected database of outcome measures.

Between April 2009 and March 2013, 915 patients underwent elective hip or knee arthroplasty. Revision cases were excluded, leaving 567 knee replacements, 315 hip replacements and 27 unicompartmental knee replacements.

In patients undergoing knee replacement, those attending joint school had shorter length of stay (4.38 vs 4.85 days, p=0.145) and better Oxford Knee Score at 6 months (p=0.026) and two years (p=0.035). Patients undergoing total hip arthroplasty had a statistically significantly shorter length of stay (3.64 vs 4.54 days, p=0.011); increased frequency of mobilising on the day of surgery (28.1% vs 22.6%, p=0.203) and higher Oxford Hip Scores (non-significant) if they attended joint school.

Our retrospective analysis demonstrates that preoperative education for patients undergoing elective total hip arthroplasty produces significantly shorter lengths of stay. There are also effects on mobilisation and outcome scores. These effects are also seen in knee arthroplasty. These results will have clinical and financial implications. Assessing cost of saved bed days alone, joint school saves the trust over £10,000 per year.

Introduction

Literature in respect to the MRI appearances of surgically confirmed spring ligament pathology is sparse. The authors conducted a retrospective review of MRI examinations comprising 13 patients with surgically proven spring ligament abnormality.

At the Peninsula NHS Treatment Centre in Plymouth some of the surgeons are UK trained and some trained elsewhere in Europe.

This paper examines the outcomes of a large series of joint replacements from 2006 to 2008 at a minimum of one year follow up to determine whether the place of orthopaedic specialist training makes any difference to the outcome. The same implants were used by all surgeons and the anaesthetic technique and post-operative management was identical.

1700 patients were interviewed by a structured telephone questionnaire with over 92% follow-up and the results entered into a joint replacement database. Additional data about length of stay and blood transfusion was added.

Results will be presented about length of stay, transfusion requirements, any further treatment or hospital attendance relating to the new joint, reoperation, deep or superficial infection, hip dislocation, VTE and patient satisfaction.

The surgeon's place of orthopaedic training was found to make no difference to the surgical outcome.

Introduction: The technique of quadriceps sparing knee arthroplasty involves a pure capsular incision, without violation of the extensor mechanism. This capsular incision should be placed distal to Vastus Medialis Obliquus (VMO). The termination of VMO is variable and may make the quadriceps sparing approach difficult. We initiated this study based on the hypothesis that quadriceps sparing approach may not be possible in all the patients undergoing total knee arthroplasty. We examined MRI scans of the knee joint to assess the variation in VMO muscle insertion in relation to the patella and variation of VMO muscle insertion in relation to the age.

Material and Methods: Between Jan 2005 and Dec 2005, 262 MRI scans of the knee joint were performed at our institute. We studied MRI scans of the patients aged 16 years and over. The scans with neoplasm or those without complete set of films were excluded from the study. There were 198 scans available for analysis. Our cohort consisted of 106 female patients and 92 male patients with an average age of 43 years (range 16–86 years). One hundred and thirty four patients were aged less than 50 years and 64 patients were 50 years or older.

We measured patellar height, VMO length on the axial views of the scans. The VMO insertion was calculated from the data and we divided the patients into proximal and distal groups in relation to the VMO termination on the patella. The proximal group included patients with VMO termination proximal to the mid-point of the patella and distal group included patients with VMO termination at or distal to the mid-point of the patella.

Results: The median height of the patella in female patients was 32mm (range 24–44mm) and in male patients was 36mm (range 28–48mm). The VMO length from the apex of the patella was 13.5mm (range 4–28mm) in female patients and 16mm (range 8–32mm) in male patients. Overall there were 119 (60%) patients in the proximal group and 79 (40%) in the distal group. In 20% of patients aged more than 50 years, VMO terminated in the distal half of the patella. In patients less than 50 years old, 50% had the VMO termination in the distal half of patella. A statistically significant inverse relationship was noted between the level of insertion of VMO and the age of the patient (p-value > 0.001, Chi-square test). There was no statistically significant relation between the level of insertion of VMO and the sex of the patient, in either age group (p-value 0.339).

Conclusion: Younger patients are statistically more likely to have a VMO which terminated at or more distal to the mid-point of patella. Therefore, the quadriceps sparing approach may not be possible in these subjects, however it is possible in majority of older patients.

Background: Independent Sector Treatment Centres (ISTC) are now providing significant volumes of elective orthopaedic care in the UK. They have been the subject of considerable publicity. The ISTC in Plymouth was the first newly built orthopaedic centre to open.

This paper describes the methods of working and analyses the early results of nearly a thousand joint replacements implanted between May 2005 and April 2006. It is the first set of such results to be become available.

Methods: Data on each case was collected prospectively and entered into a database. This included demographic information, surgical and implant data, blood loss and transfusion requirements, length of stay, patient satisfaction, readmission rate, complications and mortality. One hundred consecutive postoperative hip replacement x-rays were scored by an independent orthopaedic surgeon. The alignment of one hundred consecutive postoperative knee x-rays was evaluated by long leg views. Comparison is made to published UK and international data.

Results: Ongoing

Conclusion: Ongoing

A powered, randomised control trial was instigated to evaluate the advantages of subacromial injection of Methylprednisolone over conservative treatment in the management of partial rotator cuff injuries of the shoulder.

Consecutive patients with possible partial rotator cuff tears were reviewed at 1 week. Inclusion criteria for a diagnosis of partial rotator cuff tear included; traumatic mechanism, greater tuberosity tenderness, painful arc, and complete resolution of disability post-Bupivicaine block. Exclusion criteria included; age < 16 years, chronic shoulder disease, acromioclavicular tenderness, and abnormal shoulder radiograph. Patients were randomly allocated to receive either 1 immediate subacromial injection of 40mg Methylprednisolone (group S) or no injection (group N). Initial outcomes measured were; visual analogue pain score (0–10) and active abduction (nearest 5°), repeated at 3, 6, and 12 weeks. All patients were instructed in analgesia usage and given identical shoulder exercises.

Of 279 patients reviewed over 3 years, 90 met the inclusion criteria (6/90 patients were lost to follow-up). 50 patients were randomised to group S, 40 to group N. Mean pain score improvement at 12 weeks was comparable (S=4.95, N=4.44) (p> 0.1, CI=0.16–0.86). In patients aged > 40 years group S had significantly higher mean improvement in abduction at completion (64.28°) compared to group N (34.63°) (p< 0.02, CI 1.29–58.01). Conversely in patients aged < 40 years group S had lower mean improvements in abduction (40.55°) compared to group N (77.73°), though this was not statistically significant (p=0.1, CI 2.06–72.29)

Methylprednisolone injection is more efficacious than conservative treatment alone in some patients. This benefit appears age-dependent and consequently such treatment should be reserved for patients aged > 40 years.
