Financial impact and patient satisfaction with four different anticoagulants for hip and knee arthroplasty in patients with a previous history of VTE- A
Total hip arthroplasty (THA) is undertaken to relieve pain and to restore mobility. The orthopaedic community remains divided on the influence of surgical approach in achieving functional recovery most quickly and effectively. We report a study comparing THA performed through a posterior (Posterior) against anterior approach (Heuter). Fifty patients were prospectively enrolled and randomized for Posterior or Heuter procedures. Informed patient consent and local ethics approval was obtained. All patients received an uncemented, ceramic-on-ceramic prosthesis performed by a single surgeon. Functional outcome was assessed by time to achieve milestones of walking, stair climbing, hip movement and balance. Kinematic data on level-ground walking and the effect of fatigue was assessed using a portable gait analysis system at 6-, 12-, and 24-weeks post-operatively.Introduction

Viscosupplementation is used widely to provide symptomatic relief to patients with knee OA. This study aimed to compare the efficacy and safety of the standard (3×2ml) and single (1×6ml) dosing regimens of hylan G-F 20. Prospective, randomized, blinded (reviewers), comparative independent study. Inclusion criteria was OA knee pain e 60mm on a 100mm VAS; no prior intra articular (IA) injection. Patients were randomised to recieve 1 × 6mL or 3 × 2mL hylan G-F 20. Follow-up at 1, 6, 12, 26 and 52 weeks. Analgesics prohibited for 24 hours prior to follow-up assessments and NSAID's for 26 wks. All adverse events (AE) were recorded. Primary outcome measure: Target knee pain (VAS) at 26 weeks. Secondary outcome measures included WOMAC, Oxford knee score, SF12Introduction
Methods
We report our five-year functional results comparing navigated and conventional total knee replacement. To our knowlege this represents the first Level 1 study comparing function in navigated and conventional total knee replacement at five years. An origianl cohort of 71 patients undergoing Duracon (Stryker Orthopaedics, St. Leonards, Australia) total knee replacement without patellar resurfacing were prospectively randomised to undergo operation using computer navigation (Stryker Image Free Computer Navigation System (version 1.0; Stryker Orthopaedics))(n=35) or a jig-based method (n=36). The two groups were matched for age, gender, height, weight, BMI, ASA grade abd pre-operative deformity. All operations were performed by a single surgeon. Reviews were undertaken by senior physiotherpist blinded to participant status using validated outcome scoring tools (Knee Society Score, WOMAC Score and Short Form SF-36 Score). All patients underwent CT scanning of the implanted prosthesis as per Perth CT Knee Protocol to assess component alignment. After 5 years 24 patients in the navigated group and 22 patients in the conventional group were available for review. At 5 years no statistically significant difference was seen in any of the aforementioned outcome scores when comparing navigated and conventional groups. No statistically significant differencewas seen between 2- and 5-year results for either group. Due to the relatively low numbers in each group these data were compared with retrospective cohorts of navigated (n=100) and conventional (n=70) Duracon total knee replacements performed outwith this study over the same 5-year period. WITHIN the retrospective cohorts no statistically significant differences were found when comparing any of the aforementioned outcome scores. In addition, when comparing parallel scores between prospective and retrospective groups again no statistically significant differences were identified. At 5-years post-operatively the functional outcome between computer navigated and conventional total knee replacement appears to be no different despite the better alignment achieved using navigation.

Introduction. Comparative studies examining Fixed-Bearing (FB) and Mobile-Bearing (MB) Total Ankle Replacement (TAR) designs have demonstrated similar results and successful long-term outcomes for both. To date there has been no study directly comparing FB and MB designs of the same prosthesis. We present the first
Total hip arthroplasty (THA) has been cited as one of the most successful surgical procedures performed today. However, as hip surgeons, we desire constantly improving outcomes for THA patients with more favorable complication rates. At the same time, patients desire hip pain relief and return to function with as little interruption of life as possible. The expectation of patients has changed; they have more physical demands for strength and flexibility, and aspire to achieve more in their recreational pursuits. Additionally, health care system constraints require the THA episode of care to become more efficient as the number of procedures increases with time. These factors, over the past fifteen years, have led to a search for improved surgical approaches and peri-operative pain and rehabilitation protocols for primary THA. The orthopaedic community has seen improved pain control, length of stay, and reduction in complications with changes in practice and protocols. However, the choice of surgical approach has provided significant controversy in the orthopaedic literature. In the 2000s, the mini-posterior approach (MPA) was demonstrated as the superior tissue sparing approach. More recently, there has been a suggestion that the direct anterior approach (DAA) leads to less muscle damage, and improved functional outcomes. A recent
Patients awaiting resolution of swelling and oedema prior to ankle surgery can represent a significant burden on hospital beds. Our study assessed whether external pneumatic intermittent compression (EPIC) can reduce delays to surgery. Our
Total knee replacement (TKR) design aims to restore normal kinematics with emphasis on flexion range. The survivorship of a TKR is dependent on the kinematics in six-degrees-of-freedom (6-DoF). Stepping up, such as stair ascent is a kinematically demanding activity after TKR. The debate about design choice has not yet been informed by 6-DoF in vivo kinematics. This
Cryocompression therapy is a non-invasive and non-pharmacological modality used in managing acute post-operative inflammation and pain. A
Avulsion of the proximal hamstring tendon from the ischial tuberosity is an uncommon but significant injury. Recent literature has highlighted that functional results are superior with surgical repair over non-surgical treatment. Limited data exists regarding the optimal rehabilitation regime in post-operative patients. The aim of this study was to investigate the early interim patient outcomes following repair of proximal hamstring tendon avulsions between a traditionally conservative versus an accelerated rehabilitation regimen. In this
Hamstring grafts have been associated with reduced strength, donor site pain and muscle strains following Anterior Cruciate Ligament Reconstruction (ACLR). Traditional graft fixation methods required both semitendinosus and gracilis tendons to achieve a graft of sufficient length and diameter, but newer techniques allow for shorter, broad single tendon grafts. This study seeks to compare the outcomes between Single Tendon (ST) and Dual Tendon (DT) ACLR, given there is no
Abstract. Introduction. In revision knee arthroplasty, rotating hinge implants (RHK) have been considered to result in higher complication rates and lower survivorship when compared to constrained condylar implants (CCK). The aims of this study were to compare patient reported outcome measures (PROMs), complication rates and survivorship of RHK and CCK used in revision arthroplasty at a single, high volume elective orthopaedic centre with previously validated bespoke database. Methodology. One hundred and eight patients who underwent revision knee arthroplasty with either CCK or RHK and matched our inclusion criteria were identified. EQ5D, Health State and Oxford Knee Scores were collected pre-operatively and at 1 year post-operatively. Complication data was collected at 6 weeks, 6 months, 1 year and 2 years post-operatively. NJR data was interrogated, in addition to our own database, to investigate implant survival. Results. There was no statistically significant difference between RHK and CCK in implant survival at two to twelve years of follow up. In addition, we observed no statistically significant difference in the PROMs scores and complication rates of the two implants. Conclusion. This study shows that both the RHK and CCK remain viable options in revision arthroplasty, the implant survival and complication rate were comparable. We recommend
Abstract. Introduction. Cryocompression therapy after knee surgery is widely utilised for post-operative rehabilitation. Skin temperature should be reduced to 10–15°C to maximise the therapeutic benefits while avoiding risks of adverse events. Some cryocompression devices offer control over the temperature of the ice-water circulated through a cuff. The degree to which this corresponds to the achieved skin temperature during a treatment is unknown. Methods. 30 healthy participants volunteered for this
Tranexamic Acid (TXA) is now commonly used in major surgical operations including orthopaedics. The TRAC-24 randomised control trial aimed to assess if an additional 24 hours of TXA post – operatively in primary total hip (THA) and total knee arthroplasty (TKA) reduced blood loss. Contrary to other orthopaedic studies to date this trial included high risk patients. This paper presents the results of a cost analysis undertaken alongside this RTC. TRAC-24 was a
Total knee arthroplasty(TKA) is a major surgery and the postoperative pain can be severe. Inadequate pain relief may lead to delayed mobilisation, greater risk of developing deep vein thrombosis, coronary ischemia, poor wound healing, longer hospital stay and decreased patient satisfaction. Severe postoperative pain also increase the risk of developing long term persisting pain. Conventional pain managements with intermittent parenteral opioids and non-steroid anti-inflammatory drugs have been proved to be less effective and are often lead to unwanted side effect. Currently, there is a trend to use multimodal pain management to minimize narcotic consumption and to avoid narcotic-related side effects. The use of transdermal opioid patch has not been well established. The purpose of this study was to investigate the analgesic effects of various transdermal non-opioid patches in patients after elective total knee arthroplasty in a
Abstract. Objectives. There is debate regarding the optimal surgical technique for fixing femoral diaphyseal fractures in children aged 4 to 12 years. The aim of this study was to conduct a systematic review and meta-analysis to compare the complication rate following flexible intramedullary nailing (FIN), plate fixation and external fixation (EF) for traumatic femoral diaphyseal fractures in children aged 4 to 12. Methods. We searched MEDLINE, EMBASE and CENTRAL databases for interventional and observational studies. Two independent reviewers screened, assessed quality and extracted data from the identified studies. The primary outcome was the risk of any complication. Results. Nine randomised controlled trials (RCTs) and 19 observational studies fulfilled the eligibility criteria. Within the RCTs, five analysed FIN (n=161), two analysed plates (n=51) and five analysed EF (n=168). Within the observational studies, 13 analysed FIN (n=610), seven analysed plates (n=214) and six analysed EF (n=153). The overall risk of complications was lower following plate fixation when compared to FIN (RR 0.45, 95% CI 0.28 to 0.73, p=0.001) in the observational studies. The overall risk of complications was higher following EF when compared to FIN in both RCTs (RR 1.94, 95% CI 1.25 to 3.01, p=0.003) and observational studies (RR 1.97, 95% CI 1.50 to 2.58, p<0.001). The overall risk of complications was higher following EF when compared to plate fixation in both RCTs (RR 7.42, 95% CI 1.84 to 29.98, p=0.005) and observational studies (RR 4.39, 95% CI 2.64 to 7.30, p<0.001). Conclusions. This study reports a significantly decreased relative risk of complications when femoral diaphyseal fractures in children aged 4 to 12 are managed with plates. The overall quality of evidence is low, highlighting the need for a
Anterior surgical approaches for total hip arthroplasty (THA) have increased popularity due to expected faster recovery and less pain. However, the direct anterior approach (Heuter approach which has been popularised by Matta) has been associated with a higher rate of early revisions than other approaches due to femoral component loosening and fractures. It is also noted to have a long learning curve and other unique complications like anterior femoral cutaneous and femoral nerve injuries. Most surgeons performing this approach will require the use of an expensive special operating table. An alternative to the direct anterior approach is the anterior-based muscle-sparing approach. It is also known as the modified Watson-Jones approach, anterolateral muscle-sparing approach, minimally invasive anterolateral approach and the Röttinger approach. With this technique, the hip joint is approached through the muscle interval between the tensor fascia lata and the gluteal muscles, as opposed to the direct anterior approach which is between the sartorius and rectus femoris and the tensor fascia lata. This approach places the femoral nerve at less risk for injury. I perform this technique in the lateral decubitus position, but it can also be performed in the supine position. An inexpensive home-made laminated L-shaped board is clamped on end of table allowing the ipsilateral leg to extend, adduct, and externally rotate during the femoral preparation. This approach for THA has been reported to produce excellent results. One study reports a complication rate of 0.6% femoral fracture rate and 0.4% revision rate for femoral stem loosening. In a
Introduction and Objective. The most common paediatric orthopaedic injury requiring hospital admission is a femoral fracture. There is debate regarding the optimal surgical technique for fixing femoral diaphyseal fractures in children aged 4 to 12 years. The National Institute for Health and Care Excellence (NICE) and the American Academy of Orthopaedic Surgeons (AAOS) have issued relevant guidelines, however, there is limited evidence to support these. The aim of this study was to conduct a systematic review and meta-analysis to compare the complication rate following flexible intramedullary nailing (FIN), plate fixation and external fixation (EF) for traumatic femoral diaphyseal fractures in children aged 4 to 12. Materials and Methods. We searched MEDLINE, EMBASE and CENTRAL databases for interventional and observational studies. Two independent reviewers screened, assessed quality and extracted data from the identified studies. The primary outcome was the risk of any complication. Secondary outcomes assessed the risk of pre-specified individual complications. Results. Nine randomised controlled trials (RCTs) and 19 observational studies (six prospective and 13 retrospective) fulfilled the eligibility criteria. Within the RCTs, five analysed FIN (n=161), two analysed plates (n=51) and five analysed EF (n=168). Within the observational studies, 13 analysed FIN (n=610), seven analysed plates (n=214) and six analysed EF (n=153). The overall risk of complications was lower following plate fixation when compared to FIN fixation (RR 0.45, 95% CI 0.28 to 0.73, p=0.001) in the observational studies. The overall risk of complications was higher following EF when compared to FIN fixation in both RCTs (RR 1.94, 95% CI 1.25 to 3.01, p=0.003) and observational studies (RR 1.97, 95% CI 1.50 to 2.58, p<0.001). The overall risk of complications was higher following EF when compared to plate fixation in both RCTs (RR 7.42, 95% CI 1.84 to 29.98, p=0.005) and observational studies (RR 4.39, 95% CI 2.64 to 7.30, p<0.001). Conclusions. Although NICE and the AAOS recommend FIN for femoral diaphyseal fractures in children aged 4 to 12, this study reports a significantly decreased relative risk of complications when these injuries are managed with plates. Our findings provide valuable information to healthcare professionals who are involved in discussing the risk and benefits of different management options with patients and their families. The overall quality of evidence is low, highlighting the need for a rigorous
