Aims

The main objective of this study was to examine whether the Oxford Shoulder Score (OSS) demonstrated floor or ceiling effects when used to measure outcomes following shoulder arthroplasty in a large national cohort. Secondary objectives were to assess its pain and function subscales, and to identify independent predictors for patients achieving a postoperative ceiling score following shoulder arthroplasty.

Methods

Secondary database analysis of the National Joint Registry (NJR), which included 48,270 patients undergoing shoulder arthroplasty, was conducted. The primary outcome measure was the OSS. Secondary outcome measures were the OSS-Function Component Subscale and OSS-Pain Component Subscale. Floor and ceiling effects were considered to be present if > 15% of patients scored either the lowest or highest possible score. Logistic regression analysis was used to identify independent predictors for scoring the highest possible OSS score postoperatively.

Background

Scaphoid fractures with displacement have a higher incidence of nonunion and unite in a humpback position that can cause pain and reduced movement, strength and function. The aim of this study is to review the evidence available and establish the risk of nonunion associated with management of displaced scaphoid fractures in a plaster cast.

Methods

Electronic databases were searched using the MeSH (Medical Subject Headings) controlled vocabulary (scaphoid fractures, AND'd with explode displaced, or explode nonunion, or explode non-healing or explode cast immobilisation, or explode plaster, or explode surgery). As no randomised or controlled studies were identified, the search was limited to observational studies based on consecutive cases with displaced scaphoid fractures treated in a plaster cast. The criterion for displacement was limited to gap or step of more than 1mm. The ‘random effects’ calculation was used to allow for the possibility that the results from the separate studies differ more than would be expected by chance.

Purpose of the Study

To identify trends in patient satisfaction of their knee arthroplasty, total and unicompartmental, one year post primary knee arthroplasty surgery, with reference to age, gender and primary diagnosis, from 1990 to 2008.

Methods & Results

The Trent Arthroplasty Register was established in 1990 to collect prospective data on knee arthroplasty surgery Data has been recorded relating to 48,929 knee arthroplasties in the period 1990-2008. Self-administered questionnaires were mailed to patients 1 year after their surgery. This PROMS data has been analysed to identify trends in 25,521 patients

62% (24,648) of knee arthroplasties were performed for osteoarthritis and 32% (1,233) for rheumatoid arthritis. 83.6% of osteoarthritic patients (20,244) were satisfied with their knee 1 yr post surgery, 8.5% (2055) unsure and 7.9% dissatisfied. Comparable figures for patients with rheumatoid arthritis were 81.3% (1,028) satisfied, 10.3% (130) unsure and 8.4% dissatisfied. Overall, there was no significant difference in satisfaction rates between different diagnostic groups of patients. In osteoarthritic patients, satisfaction rates have remained the same throughout the last 18 years, in different time periods. The satisfaction rate was 83.2% for the period 1990-1994, 80.9% for 1995-1999, 86.5% for 2000-2004 and 84.1% for 2005-2007. There was no statistically significant difference between the levels of satisfaction for these time periods. The age of the patient did not affect the satisfaction rate.

Purpose

To identify if the age of the patient was related to satisfaction rates 1 year following unicompartmental knee replacement, in a generalist setting in the U.K.

Methods & Results

Unicompartmental knee replacement (UKR) is a treatment option for patients presenting with isolated medial compartmental osteoarthritis. In many cases, such patients are aged 65 years or younger. The Trent Arthroplasty Register was established in 1990 collecting prospective data on knee arthroplasties performed in this region of the U.K. Self completed questionnaires were sent to 1081 patients who had had a unicompartmental knee arthroplasty 1 year post surgery.

Completed questionnaires were received from 648 patients (60% return rate). Of these patients, 80.2% (451) reported being satisfied, 6.6% (37) unsure of their satisfaction and 13.2% (74) dissatisfied. 78% of those in the 55 or under group (n=92) were satisfied relative to 77.6% in 56-65 yr group (n=264), 90.6% for 66-75 yrs (n=202) and 87.6% for 75+ yrs (73).

Increasing age appears to correlate with increased satisfaction rates. Of those who were dissatisfied, severe pain was the primary reason given as a cause for dissatisfaction. In comparison, patients undergoing total knee arthroplasty (TKA), who were sent identical questionnaires, demonstrated no difference in satisfaction rates in each of the different age groups. The overall satisfaction rate in such patients was 90%.
