OBJECTIVES To determine chronic opioid use pre-THA (total hip arthroplasty) and post-THA, and risk factors for persistent or new chronic opioid use post-THA. DESIGN Retrospective cohort study. SETTING Australian Government Department of Veterans' Affairs health claims database. PARTICIPANTS 9525 patients who had an elective unilateral THA between 1/01/2001 and 12/31/2012. PRIMARY OUTCOM...

IMPORTANCE There are concerns about increased mortality in patients with metal-on-metal bearings in total hip arthroplasty (THA). OBJECTIVE To determine the mortality and the morbidity in patients with metal-on-metal articulations (MOM THA) compared to patients with non-metal-on-metal articulations (non-MOM THA) after primary total hip arthroplasty. DATA SOURCES Search of PubMed, MEDLINE, E...

OBJECTIVE To study the HRQOL in veterans with prevalent total knee arthroplasty (TKA) or total hip arthroplasty (THA) and compare them with age- and gender-matched US population and control veteran population without these procedures. METHODS A cohort study and cross-sectional survey on veterans obtained demographics and HRQOL with Short-Form 36 for veterans (SF-36V). Veterans were categorize...

OBJECTIVE Subtle deformities of the hip joint are implicated in the etiology of osteoarthritis (OA) of the hip. Parameters that quantify these deformities may aid understanding of these associations. We undertook this study to examine relationships between such parameters and the 19-year risk of total hip arthroplasty (THA) for end-stage OA. METHODS A new software program designed for measuri...

Background and purpose - According to previous Nordic Arthroplasty Register Association (NARA) data, the 10-year implant survival of cemented total hip arthroplasties (THAs) is 94% in patients aged 65-74 and 96% in patients aged 75 or more. Here we report a brand-level comparison of cemented THA based on the NARA database, which has not been done previously. Patients and methods - We determined...

BACKGROUND The number of septic total hip arthroplasty (THA) revisions is increasing continuously, placing a growing financial burden on hospitals. Orthopedic departments performing septic THA revisions have no basis for decision making regarding resource allocation as the costs of this procedure for the departments are unknown. It is widely assumed that septic THA procedures can only be perfor...

There is rare literature elaborating the complex total hip arthroplasty (THA) in patients with osteopetrosis who experienced malunion from femoral neck fracture. We have summarized the failure experience of the complex THA in osteopetrosis. Learned from the resurgery in the case reported by this paper, we recommend to highlight the initial stability of the prosthesis and not to overestimate the...

Introduction Total hip arthroplasty (THA) is widely successful for the treatment of end-stage hip disease. It significantly improves the quality of a patient’s life by reducing both pain and functional limitation. Many studies have demonstrated excellent survivorship following THA. However, bone resorption, or osteolysis, has emerged as a major concern regarding long-term THA survival. The inci...

This study aims to propose latitude cut deviation for differentiating hip arthroplasty types and evaluate its diagnostic utility in distinguishing total (THA) from hemiarthroplasty using radiography. After assessing various cup designs top manufacturers THA hemiarthroplasty, we conducted a retrospective on 40 patients (20 20 hemiarthroplasty). Three readers independently evaluated the radiograp...
