Abstract: Total hip arthroplasty (THA) has been performed for nearly 50 years. Between 2006 and 2012, more than 600,000 metal-on-metal THA procedures were performed in the United States. This article reviews the production of metal wear debris in a metal-on-metal articulation and the interaction of cobalt and chromium ions that ultimately led to a dramatic decline in the use of metal-on-metal THA articulations. Additionally, the article reviews mechanisms of metal wear, … Read the Rest

Patients who underwent primary hip arthroscopy experienced greater improvement in patient-reported outcome scores at 2-year follow-up compared with patients who underwent revision arthroscopy, according to results presented at the Arthroscopy Association of North America Annual Meeting…
…“The relative risk of total hip arthroplasty was often two-times [greater] after revision arthroscopy compared to primary,” Parth Lodhia, MD, said in his presentation…… Read the Rest
There are several reported disadvantages with conventional-length femoral stems in cementless total hip arthroplasty (THA). Therefore, various efforts have been made to develop a specific femoral short stem to improve physiologic bone remodeling at the femoral aspect of a cementless THA. However, there are potential disadvantages with specific femoral short stems, such as malalignment, inadvertent subsidence, and potential proximal femoral fracture. Therefore, the authors quantitatively compared radiographic and clinical outcomes as … Read the Rest
March 2016 The purpose of this study was to analyze the hospital, clinical, and patient factors associated with inpatient readmission following total hip arthroplasty (THA) in the Medicare population and to understand the primary reasons for readmission…
…The top five most frequently reported primary reasons for 30-day readmission in THA were procedure related : dislocation (5.9%), deep infection (5.1%), wound infection (4.8%), periprosthetic fracture (4.4%), or hematoma (3.4%). The top five … Read the Rest
There were no clinically relevant differences in early postoperative mortality between simultaneous and staged bilateral surgery in healthy patients. Advanced age, RA, a high ASA class and male sex increased the risk of death within 90 days. There may be an issue with enhanced risk of implant revision in patients with simultaneous bilateral THA that needs to be explored further…
…THA is considered a safe procedure. The early postoperative mortality is … Read the Rest

Opioid use beyond the first 3 months following total hip replacement is associated with a greater likelihood of revision surgery later for older adults. Based on a retrospective study, patients who continued opioid analgesia in the second 90-day postoperative period were more than twice as likely to require revision 1 year after their operation as those who had stopped opioid therapy by that point. At 5 years postoperatively, meanwhile, … 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 users, the study showed that … Read the Rest

The surgical approach to total hip replacement (THR)—either from the front of the body or the side/back (anterior versus posterior)—has no impact on outcomes six months after surgery, according to research presented today at the 2016 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS).
Total hip replacement is extremely common with more than 300,000 surgeries performed in the U.S. each year. Traditionally, most THRs … Read the Rest

In patients with appropriate indications, total hip arthroplasty performed in an outpatient setting is safe and effective, according to study data presented here.
Researchers culled data from an institutional registry for 549 patients who underwent a mini-posterior approach for total hip arthroplasty at a freestanding independent ambulatory surgical center between 2008 and 2014.… Read the Rest
