“…This is important as a reduction in wear can reduce osteolysis and hence aseptic loosening [29]. Some studies have found favourable wear rates for alumina on PE [19,30] compared to metal on PE, but some report the opposite [18]. Different trials have used various head sizes, different modes of implant fixation, different polyethylene materials, and a number of methods of measurement, all of which are factors making comparisons of different trials difficult or impossible.…”

Purpose Wear is a major contributor to osteolysis and aseptic loosening of total hip replacements (THR). Both alumina (Al 2 O 3 ) and cobalt-chrome (CoCr) femoral heads are commonly used. We investigated wear comparing alumina heads to cobalt-chrome heads against conventional cemented polyethylene (PE) cups for up to ten years. Methods Linear wear was measured with radiostereometry (RSA). Our material was derived from two prospective randomised trials that investigated fixation of femoral stems, not wear, and was evaluated retrospectively (Level III). Results The mean (95% CI) proximal head penetration was 0.96 mm (0.68-1.23) in the cobalt-chrome group and 0.42 mm (0.30-0.53) in the alumina group at ten years (P=0.001). The mean (95% CI) 3D penetration was 1.07 mm (0.79-1.35) and 0.53 mm (0.38-0.63), respectively, at ten years (P=0.001). Conclusion Alumina heads performed better than cobaltchrome heads in this study after ten-year follow-up.

“…The introduction of aluminium femoral heads reduced rates of linear and volumetric wear in vivo. Kusaba [ 166 ] studied frictional torque in 67 prosthetic cups, 30 combined with aluminium heads and 37 with metal heads, and reported that the worn alumina heads remain smoother than the new cobalt chrome heads (0.13 mm/year vs. 0.19 mm/year).…”

Updates on Biomaterials Used in Total Hip Arthroplasty (THA)

One of the most popular and effective orthopedic surgical interventions for treating a variety of hip diseases is total hip arthroplasty. Despite being a radical procedure that involves replacing bone and cartilaginous surfaces with biomaterials, it produces excellent outcomes that significantly increase the patient’s quality of life. Patient factors and surgical technique, as well as biomaterials, play a role in prosthetic survival, with aseptic loosening (one of the most common causes of total hip arthroplasty failure) being linked to the quality of biomaterials utilized. Over the years, various biomaterials have been developed to limit the amount of wear particles generated over time by friction between the prosthetic head (metal alloys or ceramic) and the insert fixed in the acetabular component (polyethylene or ceramic). An ideal biomaterial must be biocompatible, have a low coefficient of friction, be corrosion resistant, and have great mechanical power. Comprehensive knowledge regarding what causes hip arthroplasty failure, as well as improvements in biomaterial quality and surgical technique, will influence the survivability of the prosthetic implant. The purpose of this article was to assess the benefits and drawbacks of various biomaterial and friction couples used in total hip arthroplasties by reviewing the scientific literature published over the last 10 years.

“…Bragdon 33 Only four hips were evaluated and at 3-6 years from primary surgery, there was no discernable difference between ceramic and metal head wear rates. Kusaba 34 however retrieved 159 prosthesis and found that the alumina heads, although worn, remained smoother than new cobalt chrome heads. A significant reduction of polyethylene wear when coupled with alumina was also demonstrated.…”

The optimum choice of bearing surfaces in total hip arthroplasty, particularly in the younger and more active patient, remains controversial. Despite several studies demonstrating good long-term results for the metal-on-polyethylene articulation, there has been a recent vogue towards the utilisation of hard-on-hard bearings for younger patients due, in part, to concerns regarding polyethylene induced osteolysis. However, well-documented complications concerning metal-on-metal bearings and the risk of fracture in ceramic-on-ceramic bearings have raised concerns regarding the principle of the hard-on-hard bearing in the active patient. With recent technological advancements in the manufacture of both polyethylene and alumina ceramics, the in vitro properties of each material with regards to strength and toughness have been significantly improved. In addition, ceramic femoral heads have consistently been shown to produce less in vivo polyethylene wear than similar sized metal heads. This paper aims to critically review the biomechanical, in vivo and clinical studies related to the use of the ceramic on polyethylene bearing, and highlights its potential use as the preferred bearing for a young adult hip replacement.
