Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant. Hip replacement surgery can be performed as a total replacement or a hemi (half) replacement. This can relieve pain, help hip joint work better, and improve walking and other movements. Now, hip replacement surgery is performed over 300,000 times each year in the U.S. to repair severe hip damage ...

35 Background. Preclinical durability testing of hip replacement implants is standardised by 36 ISO-14242-1 (2002) which is based on historical inverse dynamics analysis using data 37 obtained from a small sample of normal healthy individuals. It has not been established 38 whether loading cycles derived from normal healthy individuals are representative of loading 39 cycles occurring in patien...

BACKGROUND Patient-Reported Outcome (PRO) measurement is a method for measuring perceptions of patients on their health and quality of life. The aim of this paper is to present the results of PRO measurements in total hip and knee replacement as routinely collected during 20 years of surgery in a university hospital setting. METHODS Data of consecutive patients between 1993 and 2014 were coll...

BACKGROUND Preclinical durability testing of hip replacement implants is standardised by ISO-14242-1 (2002) which is based on historical inverse dynamics analysis using data obtained from a small sample of normal healthy individuals. It has not been established whether loading cycles derived from normal healthy individuals are representative of loading cycles occurring in patients following tot...

BACKGROUND A discrepancy in leg length and femoral offset restoration is the leading cause of patient dissatisfaction in hip replacement surgery and has profound implications on patient quality of life. The aim of this study is to compare biomechanical hip reconstruction in hip resurfacing, large-diameter femoral head hip arthroplasty and conventional total hip replacement. METHOD Sixty patie...

The best treatment for the active and lucid elderly patient with a displaced intracapsular fracture of the femoral neck is still controversial. Randomised controlled trials have shown that a primary total hip replacement is superior to internal fixation as regards the need for secondary surgery, hip function and health-related quality of life. Despite good results achieved with total hip replac...

BACKGROUND Knee pain is nearly twice as prevalent as hip pain in elderly people, yet knee replacement is far less common than hip replacement. AIM To investigate whether systematic differences in the primary care management of hip versus knee problems might explain the disparate rates of joint replacement. DESIGN OF STUDY Cross-sectional, population-based postal survey. SETTING Random sam...

Juvenile idiopathic arthritis is the leading cause of hip replacement in young children. However, arthroplasty in this population is challenging with several concerns about quality of the growing bone, young age for revision surgery, and difficulties in potential several revisions. In this study we introduce a case of a 12-year old who is one of the youngest patients to undergo revision hip art...

OBJECTIVES To summarise epidemiological data on the frequency of hip replacements in the countries of the developed world, especially in countries of the Organisation for Economic Cooperation and Development (OECD), and to investigate whether missing consensus criteria for the indication for total hip replacement (THR) result in different replacement rates. METHODS Country-specific hip replac...
