Ultra-high molecular weight polyethylene (UHMWPE) continues to be the gold standard bearing surface in total hip arthroplasty (THA) for nearly 5 decades. Highly cross-linked UHMWPE (HXLPE) was adapted for routine use in the early 2000s to reduce the revision rates related to wear, osteolysis, and aseptic loosening resulting from conventional UHMWPE wear. Since its inception, consistent evidence showing reduced wear rates and osteolysis supports the use of HXLPE in THA. High quality studies demonstrating the advantage in long term survivorship of HXLPE over conventional UHMWPE are emerging...

INTRODUCTION: The best treatment of acetabular chondral flaps during surgery for femoroacetabular impingement (FAI) is unknown. We asked if subchondral drilling improves clinical and radiographic outcome and if there are factors predicting failure. METHODS: We treated 79 patients with symptomatic FAI and acetabular chondral flaps with surgical hip dislocation between January 2000 and December 2007. Exclusion of all patients with previous hip pathology or trauma resulted in 62 patients (80 hips)...

AIM: The aim was to present the surgical technique and clinical outcome in a series of patients treated with gamma-probe-assisted arthroscopic removal of osteoid osteoma in the hip joint. METHODS: The case series consisted of 10 patients diagnosed with osteoid osteoma of the hip, who were treated by arthroscopic nidus removal. An endoscopic gamma probe was used intraoperatively to locate the nidus and to control the extent of its removal. Residual osteoma cavities were additionally treated with an arthroscopic radiofrequency ablator...

BACKGROUND: Bisphosphonates have previously been shown to increase the density of impacted graft bone. In the present study we hypothesise that bisphosphonates also reduce early stem subsidence. We examined the effect of locally applied bisphosphonate to allografts on prosthetic micromotion and bone density in femoral stem revision with impaction grafting. METHODS: 37 patients were randomised to either clodronate or saline as local adjunct to the morsellised allograft bone...

BACKGROUND: The Exeter V40 Orthinox stem is one of the most commonly used femoral components in total hip arthroplasty. Its design, material and finish has evolved significantly from the original design established by Ling and Lee over 3 decades ago. An early problem reported with the original Exeter stem was a high rate of stem fractures. It was thought that with the new Orthinox steel used in the V40 system, the rate of stem fractures would reduce. There are reports of the Exeter V40 stem failing in a variety of locations...

BACKGROUND: The periarticular multimodal cocktail injection is currently commonly used to treat postoperative pain after total hip arthroplasty (THA). Despite its analgesic effect, it is frequently reported to cause nausea and vomiting, which are adverse effects of opioids. This study aimed to assess the efficacy of morphine as a component of a multimodal cocktail injection for providing postoperative analgesia and alleviating swelling in patients who underwent THA. MATERIALS AND METHODS: This was a prospective, single-centre, randomised controlled trial involving 100 patients scheduled for unilateral THA...

BACKGROUND: The purpose of this study is to: (1) characterise risk factors for prolonged narcotic use following total hip arthroplasty (THA); (2) examine preoperative and prolonged postoperative narcotic use as independent risk factors for complications following THA. METHODS: A national database identified primary THA patients from 2007-2015. Preoperative (POU) and prolonged postoperative narcotics users (PPU) were identified. A multivariable logistic regression analysis was utilised to identify any patient-related risk factors for prolonged use, and examined POU and PPU as risk factors for complications following THA...

BACKGROUND: Femoral component offset influences the torque forces exerted on a femoral stem and may therefore adversely affect femoral component survival. This study investigated the influence of femoral component offset on revision rates for primary total hip replacements (THR) registered on the New Zealand Joint Registry (NZJR). METHODS: There were 106,139 primary THRs registered, resulting in 4960 revisions for any cause. There were 46,242 THRs performed using the five commonest femoral components listed on the NZJR...

BACKGROUND: We discuss the surgical results of revision surgery for patients with refractory symptomatic leg length inequality (LLI) after primary hip replacement. METHODS: This is a retrospective review of 21 patients who underwent revision for LLI after primary total hip replacement. All of them were referred to a tertiary clinic between 2006 and 2015. Leg length was measured, to the nearest mm, using Woolson's validated X-ray technique which references to centre of femoral rotation, the acetabular teardrop and the midpoint of the lesser trochanter...

INTRODUCTION: There is a paucity in the literature regarding mid-term results of microfracture in hip arthroscopy. We aim to assess 5-year outcomes of patients who underwent acetabular microfracture for full-thickness chondral lesions as a part of hip arthroscopy. METHODS: Between August 2008 and September 2011, data were prospectively gathered for patients undergoing acetabular microfracture during hip arthroscopy with minimum 5-year follow-up. All patients were assessed pre- and postoperatively, with modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score - Sports Specific Subscale (HOS-SSS), and visual analog scale (VAS)...

INTRODUCTION: The efficacy of hip precautions in preventing dislocation post total hip arthroplasty (THA) has been questioned in recent literature. From 2014 our centre ceased routinely prescribing them due to lack of evidence. We investigate the effect of stopping these precautions on dislocation rate, patient satisfaction and Oxford hip score (OHS). METHODS: Patients who underwent primary total hip arthroplasty prior to this change in protocol ( n = 2551) and for 1 year subsequently ( n = 673) were identified...

INTRODUCTION: The growing use of cementless stems is associated with an increase in implant-related complications. This global survey study investigates which parameters orthopaedic surgeons currently consider for either cemented or cementless stem fixation in primary total hip arthroplasty (THA). METHODS: A survey regarding current practice patterns was distributed among hip arthroplasty specialists. Key questions concerned: (i) frequency of using cemented/cementless stems; (ii) frequency of using parameters which influence a choice between both; (iii) usage of specific cut-off values for parameters...

BACKGROUND: Optimising postoperative pain management after total hip arthroplasty (THA) has been associated with improved patient outcomes. However, conclusions regarding the role of liposomal bupivacaine (LB) during THA remain mixed. The purpose of this study was to determine whether substituting a standard intraoperative wound infiltrate with LB as part of a multimodal pain management protocol would decrease subsequent opioid consumption and overall length of hospital stay in patients undergoing primary THA...

INTRODUCTION: This study evaluated the effectiveness of hip resurfacing in patients with femoral deformities or retained femoral implants. Implant removal and conversion total hip replacement (CTHR) have been associated with increased operative time, blood loss, and cost. Removing intramedullary nails in particular can be difficult and can result in a more difficult recovery and/or complications. Hip resurfacing can be performed with a blocked femoral canal and has the possible additional benefits of a less-complex procedure, improved functional outcomes, better patient survivorship, and a possibly less-complicated revision should a failure occur...
