In this prospective study, 190 hip resurfacing procedures (164 participants) were performed using a cobalt-chromium femoral component and a cementless acetabular cup with a 3.8-mm highly cross-linked polyethylene acetabular liner…
…The mean follow-up was 8.5 (range, 7-10) years…
…(With Highly Cross-linked Polyethylene device) The low incidence of osteolysis and the low rate of wear found on retrievals suggest that many years of use … Read the rest
BIRMINGHAM, ENGLAND – Contrary to expectations, metal-on-metal hip resurfacing for osteoarthritis was associated with higher patient survival at 10 years than was total hip arthroplasty in a large, population-based study…
…Cumulative mortality rates were 2.8% for hip resurfacing versus 7.3% for cemented total hip replacement (THR; hazard ratio, 0.51). Ten-year mortality rates comparing hip resurfacing to uncemented THR were 2.6% and 3.2%, respectively (HR, 0.64)…

Studies were searched for in the Medline database, Embase, and the Cochrane Database of Systematic Reviews. Highest mean or median ion concentrations of Cr and Co after a minimum of 1 year of follow-up were extracted and grouped according to sample- and articulation type, and average values were calculated…
…43 studies were included and 16 different MoM implants were identified. For the different types of bearings, … Read the rest
…it may be beneficial to investigate the long-term outcome of hip resurfacings using metal-on-polyethylene in the 1980’s. We report the long-term survivorship and modes of failure of a cementless metal-on-polyethylene resurfacing.
Ongoing developments using the lessons learned from these previous generation components and utilizing modern low wear materials, e.g., cross-linked polyethylene, may … Read the rest
March 6, 2016 Decreased opioid use prior to joint replacement surgery has been linked with improved patient satisfaction and outcomes, fewer complications and a reduced need for post-surgical opioids, according to two new studies.
They found nearly 59 percent of the patients (49,617) did not use opioids prior to surgery, while 41.4 percent did. The top three prescribed opioids were hydrocodone/acetaminophen, oxycodone/acetaminophen, and oxycodone.
In opioid … Read the rest
The Polymotion Hip Resurfacing device is an allergy-free device that uses a 3mm-thick cup made with a material known as cross-linked polyethylene, one of the toughest plastics in existence.
Traditional metal-on-metal hip resurfacing uses cobalt chromium alloy, explains Mr Derek McMinn, a consultant orthopaedic surgeon at BMI Edgbaston Hospital in Birmingham, who developed the new procedure.
‘Metal reactions vary in severity, but in the worst cases … Read the rest
Although patients who underwent total hip arthroplasty experienced greater leg length discrepancy and less accurate restoration of offset compared with patients who underwent hip resurfacing arthroplasty, investigators of this retrospective study found no difference in clinical outcomes between the procedures…
…Researchers found THA significantly increased femoral offset and leg length compared with hip resurfacing arthroplasty…… Read the rest
Regardless of whether patients underwent total hip arthroplasty or surface replacement arthroplasty, 40% of young and active patients in this study experienced pain around the hip following surgery.
…420 patients younger than 60 years with a pre-symptomatic were studied…
… patients who underwent THA experienced greater overall incidence of anterior thigh pain than hip resurfacing patients…… Read the rest
