The number of patients undergoing arthroscopic surgery of the
hip has increased significantly during the past decade. It has now
become an established technique for the treatment of many intra-
and extra-articular conditions affecting the hip. However, it has
a steep learning curve and is not without the risk of complications.
The purpose of this systematic review was to determine the prevalence
of complications during and following this procedure. Preferred Reporting Items for Systematic Reviews and Meta-Analyses
guidelines were used in designing this study. Two reviewers systematically
searched the literature for complications related to arthroscopy
of the hip. The research question and eligibility criteria were
established Aims
Materials and Methods
Episodic, or bundled payments, is a concept now
familiar to most in the healthcare arena, but the models are often
misunderstood. Under a traditional fee-for-service model, each provider
bills separately for their services which creates financial incentives
to maximise volumes. Under a bundled payment, a single entity, often
referred to as a convener (maybe the hospital, the physician group,
or a third party) assumes the risk through a payer contract for
all services provided within a defined episode of care, and receives
a single (bundled) payment for all services provided for that episode.
The time frame around the intervention is variable, but defined
in advance, as are included and excluded costs. Timing of the actual payment
in a bundle may either be before the episode occurs (prospective
payment model), or after the end of the episode through a reconciliation
(retrospective payment model). In either case, the defined costs
over the defined time frame are borne by the convener. Cite this article:
Preservation of both anterior and posterior cruciate ligaments in total knee arthroplasty (TKA) can lead to near-normal post-operative joint mechanics and improved knee function. We hypothesised that a patient-specific bicruciate-retaining prosthesis preserves near-normal kinematics better than standard off-the-shelf posterior cruciate-retaining and bicruciate-retaining prostheses in TKA. We developed the validated models to evaluate the post-operative kinematics in patient-specific bicruciate-retaining, standard off-the-shelf bicruciate-retaining and posterior cruciate-retaining TKA under gait and deep knee bend loading conditions using numerical simulation.Objectives
Methods
To evaluate the outcomes of cemented total hip arthroplasty (THA)
following a fracture of the acetabulum, with evaluation of risk
factors and comparison with a patient group with no history of fracture. Between 1992 and 2016, 49 patients (33 male) with mean age of
57 years (25 to 87) underwent cemented THA at a mean of 6.5 years
(0.1 to 25) following acetabular fracture. A total of 38 had undergone
surgical fixation and 11 had been treated non-operatively; 13 patients
died at a mean of 10.2 years after THA (0.6 to 19). Patients were
assessed pre-operatively, at one year and at final follow-up (mean
9.1 years, 0.5 to 23) using the Oxford Hip Score (OHS). Implant
survivorship was assessed. An age and gender-matched cohort of THAs
performed for non-traumatic osteoarthritis (OA) or avascular necrosis
(AVN) (n = 98) were used to compare complications and patient-reported outcome
measures (PROMs).Aims
Patients and Methods
The aims of this study were to compare the mid-term outcomes
of patients with late-stage arthritis of the wrist treated with
proximal row carpectomy (PRC) and dorsal capsular interposition
(DCI) arthroplasty with a matched cohort treated with routine PRC
alone. A total of 25 arthritic wrists (24 patients) with pre-existing
degenerative changes of the proximal capitate and/or the lunate
fossa of the radius were treated with PRC + DCI over a ten-year
period. This group of patients were matched 1:2 with a group of
50 wrists (48 patients) without degenerative changes in the capitate
or lunate fossa that were treated with a routine PRC alone during
the same period. The mean age of the patients at the time of surgery
was 56.8 years (25 to 81), and the demographics and baseline range
of movement of the wrist, grip strength, Quick Disabilities of the
Arm, Shoulder, and Hand (QuickDASH) score, and Patient-Rated Wrist
Evaluation (PRWE) score were similar in both groups. Aims
Patients and Methods
Little biomechanical information is available about kinematically aligned (KA) total knee arthroplasty (TKA). The purpose of this study was to simulate the kinematics and kinetics after KA TKA and mechanically aligned (MA) TKA with four different limb alignments. Bone models were constructed from one volunteer (normal) and three patients with three different knee deformities (slight, moderate and severe varus). A dynamic musculoskeletal modelling system was used to analyse the kinematics and the tibiofemoral contact force. The contact stress on the tibial insert, and the stress to the resection surface and medial tibial cortex were examined by using finite element analysis.Objectives

We have increased the dose of tranexamic acid (TXA) in our enhanced total joint recovery protocol at our institution from 15 mg/kg to 30 mg/kg (maximum 2.5 g) as a single, intravenous (IV) dose. We report the clinical effect of this dosage change. We retrospectively compared two cohorts of consecutive patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA) surgery in our unit between 2008 and 2013. One group received IV TXA 15 mg/kg, maximum 1.2 g, and the other 30 mg/kg, maximum 2.5 g as a single pre-operative dose. The primary outcome for this study was the requirement for blood transfusion within 30 days of surgery. Secondary measures included length of hospital stay, critical care requirements, re-admission rate, medical complications and mortality rates.Objectives
Methods
Unicompartmental knee arthroplasty (UKA) has been successfully
performed in the United States healthcare system on outpatients.
Despite differences in healthcare structure and financial environment,
we hypothesised that it would be feasible to replicate this success
and perform UKA with safe day of surgery discharge within the NHS,
in the United Kingdom. This has not been reported in any other United
Kingdom centres. We report our experience of implementing a pathway to allow safe
day of surgery discharge following UKA. Data were prospectively
collected on 72 patients who underwent UKA as a day case between
December 2011 and September 2015. Aims
Patients and Methods
The aim of this prospective randomised controlled trial was to
compare non-operative and operative management for acute isolated
displaced fractures of the olecranon in patients aged ≥ 75 years. Patients were randomised to either non-operative management or
operative management with either tension-band wiring or fixation
with a plate. They were reviewed at six weeks, three and six months
and one year after the injury. The primary outcome measure was the
Disabilities of the Arm, Shoulder and Hand (DASH) score at one year.Aims
Patients and Methods
At The Hospital for Sick Children in Toronto, 21 undescended scapulae were corrected by the Woodward procedure in 20 patients over the past 18 years. The average age at operation was six years six months. The average follow-up period after operation was 8 years 9 months. Fifteen patients were girls and five were boys. All the patients had other associated abnormalities. Only one patient had a concomitant clavicular osteotomy. The average increase in glenohumeral abduction was 37 degrees. The average scapular lowering was two centimetres. Excellent or good cosmetic results were obtained in 80 per cent of patients. Ninety-three per cent of
Multimodal infiltration of local anaesthetic provides effective
control of pain in patients undergoing total knee arthroplasty (TKA).
There is little information about the added benefits of posterior
capsular infiltration (PCI) using different combinations of local
anaesthetic agents. Our aim was to investigate the effectiveness
of the control of pain using multimodal infiltration with and without
infiltration of the posterior capsule of the knee. In a double-blind, randomised controlled trial of patients scheduled
for unilateral primary TKA, 86 were assigned to be treated with
multimodal infiltration with (Group I) or without (Group II) PCI.
Routine associated analgesia included the use of bupivacaine, morphine,
ketorolac and epinephrine. All patients had spinal anaesthesia and patient-controlled
analgesia (PCA) post-operatively. A visual analogue scale (VAS)
for pain and the use of morphine were recorded 24 hours post-operatively.
Side effects of the infiltration, blood loss, and length of stay
in hospital were recorded.Aims
