We have investigated the outcome of arthroscopic revision surgery for recurrent instability of the shoulder after failed primary anterior stabilisation. We identified 40 patients with failed primary open or arthroscopic anterior stabilisation of the shoulder who had been treated by
Aims. Our aim was to perform a meta-analysis of the outcomes of revision
anterior cruciate ligament (ACL) reconstruction, comparing the use
of different types of graft. Materials and Methods. A search was performed of Medline and Pubmed using the terms
“Anterior Cruciate Ligament” and “ACL” combined with “revision”,
“re-operation” and “failure”. Only studies that reported the outcome
at a minimum follow-up of two years were included. Two authors reviewed
the papers, and outcomes were subdivided into autograft and allograft. Autograft
was subdivided into hamstring (HS) and bone-patellar tendon-bone
(BPTB). Subjective and objective outcome measures were analysed
and odds ratios with confidence intervals were calculated. Results. A total of 32 studies met the inclusion criteria. Five studies
used HS autografts, eight reported using BPTB autografts, two used
quadriceps tendon autografts and eight used various types. Seven
studies reported using allografts, while the two remaining used
both BPTB autografts and allografts. Overall, 1192 patients with
a mean age of 28.7 years (22.5 to 39) and a mean follow-up of 5.4
years (2.0 to 9.6) were treated with autografts, while 269 patients
with a mean age of 28.4 years (25 to 34.6) and a mean follow-up
of 4.0 years (2.3 to 6.0) were treated with allografts. Regarding
allografts, irradiation with 2.5 mrad was used in two studies while
the graft was not irradiated in the seven remaining studies. Reconstructions
following the use of autografts had better outcomes than those using
allograft with respect to laxity, measured by KT-1000/2000 (MEDmetric
Corporation) and the rates of complications and re-operations. Those
following the use of allografts had better mean Lysholm and Tegner
activity scores compared with autografts. If irradiated allografts
were excluded from the analysis, outcomes no longer differed between
the use of autografts and allografts. Comparing the types of autograft,
all outcomes were similar except for HS grafts which had better

BPTB grafts. Conclusion. Autografts had better outcomes than allografts in

Our aim was to determine the success rate of repeated debridement and two-stage cementless revision arthroplasty according to the type of infected total hip replacement (THR). We enrolled 294 patients (294 hips) with an infected THR in the study. There were 222 men and 72 women with a mean age of 55.1 years (24.0 to 78.0). The rate of control of infection after the initial treatment and after repeated debridement and two-stage

Aims. We compared the outcome of total hip arthroplasty (THA) in obese
patients who previously underwent bariatric surgery and those who
did not, in a matched cohort study. Patients and Methods. There were 47 THAs in the bariatric group (42 patients), and
94 THAs in the comparison group (92 patients). The mean age of the
patients was 57 years in both groups (24 to 79) and 57% of the patients
in both groups were women. The mean time between bariatric surgery
and THA was five years (four months to 12 years) in the bariatric group.
The mean follow-up after THA was three years (2 to 9). . Results. The mean BMI improved from 49.7 kg/m. 2. (35 to 75) prior
to bariatric surgery to 35.3 kg/m. 2 . (21 to 49) at the
time of THA (p <

an increased risk of re-operation (Hazard Ratio (HR) 3.2; 95% confidence

The use of large-diameter metal-on-metal (MoM)
components in total hip arthroplasty (THA) is associated with an increased
risk of early failure due to adverse local tissue reaction to metal
debris (ARMD) in response to the release of metal ions from the
bearing couple and/or head-neck taper corrosion. The aim of this
paper was to present a review of the incidence and natural history
of ARMD and the forms of treatment, with a focus on the need for
and extent of resection or debulking of the pseudotumour. An illustrative
case report is presented of a patient with an intra-pelvic pseudotumour
associated with a large diameter MoM THA, which was treated successfully
