Development of clinical assessment strategies for patients undergoing total hip arthroplasty (THA)
Total hip arthroplasty (THA) is a common surgery that people suffering from hip pain and reduced mobility, generally caused by osteoartrhosis, undergo. In the surgery the head and neck of the femur bone are replaced with a prosthesis whose ball-like head fits into a cup that is inserted into the …

Numerical optimisation of biomedical implant characteristics for increased service life.
… stress shielding which in turn could increase Total Hip Arthroplasty (THA) service life and reduce patient discomfort by employing a distributed stiffness along implant length. Research found that through distributing stiffness along THA stem length, significant reductions in stress shielding …

The Effects and Analysis of Implant Type and Surgical Approach in Total Hip Arthroplasty Dislocation Resistance
<p>Total hip arthroplasty (THA) is one of the most successful orthopaedic surgeries performed, in which the hip joint is reconstructed to decrease pain and to improve the functionality to the joint. Although these surgeries are very successful, there still remain areas for improvement, such as …

An articulated drill and hybrid tracking navigation system for orthopaedic surgery
… outcomes and decreasing the complications of the THA procedure. Besides that, after the total hip arthroplasty (THA) procedure, there is also probability of the patient ending up with unequal leg lengths, which are referred to as a leg-length discrepancy (LLD). One way to reduce the risk in THA …

(Inter)national Review of Periprosthetic Hip and Knee Fracture Diagnostic and Treatment Strategies
Periprosthetic fractures (PPF) after total hip arthroplasty (THA) and total knee arthroplasty (TKA) complicate care and hinder benchmarking. We asked: which parameters are essential for an international PPF registry? A two-round Delphi consensus with purposive and snowball sampling recruited 30 …

A Virtual Method for Establishing Femoral Stem Position in Total Hip Arthroplasty
<p>Total hip arthroplasty (THA) is one of the most successful orthopedic surgeries performed, in which the hip joint is reconstructed to improve functionality and decrease pain in the joint. Despite the success of these procedures, femoral stem misalignment remains an area that influences THA …

Variation in joint fluid composition and its effect on the tribology of replacement joint articulation
… of joint replacement prostheses, particularly in total hip arthroplasty (THA) and total knee arthroplasty (TKA). Although the tribology of joint replacement has consequently become an area of significant research, the effect of joint fluid on lubrication in the replaced joint has been largely …

Does the Intra-operatively measured Leg Length Correction compare to the Post-operative radiograph in Total Hip Replacement surgery?
… using the Vertical Measurement SystemTM (VMS) in total hip arthroplasty (THA), with the LLC measured on a 6-week post-operative Xray. We also wanted to quantify any residual leg length discrepancy (LLD) using this method. Patients and Methods A prospective cohort study was conducted, in which …

Displaced intracapsular neck of femur fractures: dislocation rate after total hip arthroplasty
… common orthopaedic complications after primary total hip arthroplasty (THA). The reported dislocation rate in elective THR is 5 - 8%. This number increases up to 22% for THA done for neck of femur fractures. Larger femoral head sizes increase the head-neck ratio and range of motion before …

The adoption of laser melting technology for the manufacture of functionally graded cobalt chrome alloy femoral stems
Total Hip Arthroplasty (THA) is an orthopaedic procedure that is performed to reduce pain and restore the functionality of hip joints that are affected by degenerative diseases. The outcomes of THA are generally good. However, the stress shielding of the periprosthetic femur is a factor that can …

The Fc Orth (SA) final examination The short-term outcome of hip revision arthroplasty with Trabecular Metal™ components and augments
… are increasingly being used in revision hip arthroplasty as they facilitate ingrowth, provide a useful mechanism to deal with bone loss and may decrease the risk of infection. The purpose of this audit was to describe: 1) the short-term radiological outcomes of revision hip arthroplasty …

Automated determination of the theoretical range of hip motion prior to total hip arthroplasty using 3D models created from pelvic CT scans
One of the major concerns following a total hip arthroplasty (THA) is the risk of dislocation: the artificial femoral head pops out of the replaced acetabulum due to a leverage effect. It affects about 4,000 patients a year in the UK, for 80,000 THA1. To prevent this complication, surgeons would …

Recovery in Year Two of Adults After Undergoing TKA and THA: Implications for Understanding Recovery, Care Delivery, and Referral to Community Exercise Programs
Total knee arthroplasty (TKA) and total hip arthroplasty (THA) are orthopaedic surgeries to manage end-stage osteoarthritis. A year after undergoing TKA or THA, some patients report physical function limitations and unmet physical activity expectations. Limited knowledge of physical function …

In Vivo Wear Performance of Highly-crosslinked Polyethylene in Total Hip Arthroplasty
… (HXLPE) has been a major advancement in total hip arthroplasty (THA), significantly reducing wear rates and the need for revisions compared to conventional ultra-high molecular weight polyethylene. However, volumetric wear and the associated periprosthetic tissue response remain one of …

Determination of the Functional Relationship Between Lumbar Lordosis and Pelvic Tilt
… spine then alters the position of the pelvis and hip joints, which may impact the function and hip contact patterns. Several studies have shown that patients with spinal pathology, such as arthritis, often have a coexisting hip pathology or subsequently develop hip pathology, and it is estimated …
