The benefit of arthroscopy of the hip in the
treatment of femoroacetabular impingement (FAI) in terms of quality
of life (QoL) has not been reported. We prospectively collected
data on 612 patients (257 women (42%) and 355 men (58%)) with a
mean age at the time of surgery of 36.7 years (14 to 75) who underwent
arthroscopy of the hip for FAI under the care of a single surgeon.
The minimum follow-up was one year (mean 3.2 years (1 to 7)). The
responses to the modified Harris hip score were translated using
the Rosser Index Matrix in order to provide a QoL score. The mean
QoL score increased from 0.946 (-1.486 to 0.995) to 0.974 (0.7 to
1) at one year after surgery (p <
0.001). The mean QoL score
in men was significantly higher than in women, both before and one
year after surgery (both p <
0.001). However, the mean change
in the QoL score was not statistically different between men and
women (0.02 (-0.21 to 0.27) and 0.04 (-0.16 to 0.87), respectively;
p = 0.12). Linear regression analysis revealed that the significant predictors
of a change in QoL score were pre-operative QoL score (p <
0.001)
and gender (p = 0.04). The lower the pre-operative score, the higher
the gain in QoL post-operatively (ρ = -0.66; p <
0.001). One
year after surgery the QoL scores in the 612 patients had improved
in 469 (76.6%), remained unchanged in 88 (14.4%) and had deteriorated
in 55 (9.0%).
We randomised 31 patients with acute tears of the anterior cruciate ligament (ACL) to receive either early (within 2 weeks) or delayed (8 to 12 weeks) reconstruction using a quadruple hamstring graft in order to determine if there was any functional advantage to early reconstruction.
Since redesign of the Oxford phase III mobile-bearing unicompartmental
knee arthroplasty (UKA) femoral component to a twin-peg design,
there has not been a direct comparison to total knee arthroplasty
(TKA). Thus, we explored differences between the two cohorts. A total of 168 patients (201 knees) underwent medial UKA with
the Oxford Partial Knee Twin-Peg. These patients were compared with
a randomly selected group of 177 patients (189 knees) with primary
Vanguard TKA. Patient demographics, Knee Society (KS) scores and
range of movement (ROM) were compared between the two cohorts. Additionally,
revision, re-operation and manipulation under anaesthesia rates
were analysed.Aims
Patients and Methods
We report the findings of an independent review
of 230 consecutive Birmingham hip resurfacings (BHRs) in 213 patients
(230 hips) at a mean follow-up of 10.4 years (9.6 to 11.7). A total
of 11 hips underwent revision; six patients (six hips) died from
unrelated causes; and 13 patients (16 hips) were lost to follow-up.
The survival rate for the whole cohort was 94.5% (95% confidence
interval (CI) 90.1 to 96.9). The survival rate in women was 89.1%
(95% CI 79.2 to 94.4) and in men was 97.5% (95% CI 92.4 to 99.2).
Women were 1.4 times more likely to suffer failure than men. For
each millimetre increase in component size there was a 19% lower
chance of a failure. The mean Oxford hip score was 45.0 (median
47.0, 28 to 48); mean University of California, Los Angeles activity
score was 7.4 (median 8.0, 3 to 9); mean patient satisfaction score
was 1.4 (median 1.0, 0 to 9). A total of eight hips had lysis in
the femoral neck and two hips had acetabular lysis. One hip had
progressive radiological changes around the peg of the femoral component.
There was no evidence of progressive neck narrowing between five
and ten years. Our results confirm that BHR provides good functional outcome
and durability for men, at a mean follow-up of ten years. We are
now reluctant to undertake hip resurfacing in women with this implant.

In 1999, we developed a technique for biological
reconstruction after excision of a bone tumour, which involved using
autografts of the bone containing the tumour treated with liquid
nitrogen. We have previously reported the use of this technique
in 28 patients at a mean follow up of 27 months (10 to 54). In this study, we included 72 patients who underwent reconstruction
using this technique. A total of 33 patients died and three were
lost to follow-up, at a mean of 23 months (2 to 56) post-operatively,
leaving 36 patients available for a assessment at a mean of 101
months 16 to 163) post-operatively. The methods of reconstruction included
an osteo-articular graft in 16, an intercalary in 13 and, a composite
graft with prosthesis in seven. Post-operative function was excellent in 26 patients (72.2%),
good in seven (19.4%), and fair in three (8.3%) according to the
functional evaluation system of Enneking. No recurrent tumour occurred
within the grafts. The autografts survived in 29 patients (80.6%),
and the rates of survival at five and ten years were 86.1% and 80.6
%, respectively. Seven of 16 osteo-articular grafts (44%) failed
because of fracture or infection, but all the composite and intercalary
grafts survived. The long-term
Surgeons need to be able to measure angles and distances in three dimensions in the planning and assessment of knee replacement. Computed tomography (CT) offers the accuracy needed but involves greater radiation exposure to patients than traditional long-leg standing radiographs, which give very little information outside the plane of the image. There is considerable variation in CT radiation doses between research centres, scanning protocols and individual scanners, and ethics committees are rightly demanding more consistency in this area. By refining the CT scanning protocol we have reduced the effective radiation dose received by the patient down to the equivalent of one long-leg standing radiograph. Because of this, it will be more acceptable to obtain the three-dimensional data set produced by CT scanning. Surgeons will be able to document the impact of implant position on
We reviewed the surgical treatment and oncological results of 40 patients with pathological fractures from localised osteosarcoma of the long bones to determine the
We present the prevalence of multiple fractures
in the elderly in a single catchment population of 780 000 treated over
a 12-month period and describe the mechanisms of injury, common
patterns of occurrence, management, and the associated mortality
rate. A total of 2335 patients, aged ≥ 65 years of age, were prospectively
assessed and of these 119 patients (5.1%) presented with multiple
fractures. Distal radial (odds ratio (OR) 5.1, p <
0.0001), proximal humeral
(OR 2.2, p <
0.0001) and pelvic (OR 4.9, p <
0.0001) fractures
were associated with an increased risk of sustaining associated
fractures. Only 4.5% of patients sustained multiple fractures after
a simple fall, but due to the frequency of falls in the elderly
this mechanism resulted in 80.7% of all multiple fractures. Most
patients required admission (>
80%), of whom 42% did not need an
operation but more than half needed an increased level of care before
discharge (54%). The standardised mortality rate at one year was
significantly greater after sustaining multiple fractures that included
fractures of the pelvis, proximal humerus or proximal femur (p <
0.001). This mortality risk increased further if patients were <
80 years of age, indicating that the existence of multiple fractures after
low-energy trauma is a marker of mortality.
We examined the roles of methylmethacrylate (MMA) monomer and cementing technique in the formation, and haemodynamic
We have previously reported in 57 patients (60 hips) with a past history of Legg-Calvé-Perthes’ disease at a mean of 34 years after the onset of symptoms. From this original group, 48 patients (51 hips) were also available for review after a mean of 50.2 years. We consider that the best prognostic indicator for the hip is the shape of the femoral head at skeletal maturity. Normal or flattened spherical heads present few problems. Irregular or very irregular heads are associated with a poor
Depression can significantly affect quality of life and is associated

following surgery. Although depression has been linked to poorer
outcomes following orthopaedic trauma, total joint arthroplasty
and spinal surgery, we wished to examine the impact of depression
in elective total shoulder arthroplasty (TSA) as this has not been
previously explored. The United States Nationwide Inpatient Sample (NIS) was used
to identify patients undergoing elective TSA over a ten-year period.
Between 2002 and 2012, 224 060 patients underwent elective TSA.Aims
Patients and Methods
In a prospective, randomised study on the repair of tears of the rotator cuff we compared the clinical results of two suture techniques for which different suture materials were used. We prospectively randomised 100 patients with tears of the rotator cuff into two groups. Group 1 had transosseous repair with No. 3 Ethibond using modified Mason-Allen sutures and group 2 had transosseous repair with 1.0 mm polydioxanone cord using modified Kessler sutures. After 24 to 30 months the patients were evaluated clinically using the Constant score and by ultrasonography. Of the 100 patients, 92 completed the study. No significant statistical difference was seen between the two groups: Constant score, 91% vs 92%; rate of further tear, 18% vs 22%; and revision, 4% vs 4%. In cases of further tear the
The aim of this study was to establish what happens to patients
in the long term after endoprosthetic replacement for a primary
malignant tumour of bone. We conducted a retrospective analysis of a prospectively maintained
database to identify all patients who had undergone an endoprosthetic
replacement more than 25 years ago and who were still alive. Their
outcomes were investigated with reference to their complications and
need for further surgery. A total of 230 patients were identified.
Their mean age at diagnosis was 20.7 years (five to 62). The most
common diagnosis was osteosarcoma (132). The most common site was
the distal femur (102). Aims

We assessed the predictive value of the macroscopic and detailed microscopic appearance of the coracoacromial ligament, subacromial bursa and rotator-cuff tendon in 20 patients undergoing subacromial decompression for impingement in the absence of full-thickness tears of the rotator cuff. Histologically, all specimens had features of degenerative change and oedema in the extracellular matrix. Inflammatory cells were seen, but there was no evidence of chronic inflammation. However, the
