  • First Reported Series of Outpatient Total Knee Arthroplasty in the Middle East

    Outpatient total knee arthroplasty (TKA) is becoming more commonplace in the United States. Alternatively, the current practice in the Middle East involves an inpatient stay of 7-10 days in the hospital after TKA. This study reports the early results of the first reported series of outpatient TKA performed on patients in the Middle East and compares the clinical and functional outcomes with those of patients who underwent inpatient TKA.

  • Contact conditions for total hip head-neck modular taper junctions with microgrooved stem tapers

    Implant failure due to fretting-corrosion of head-neck modular junctions is a rising problem in total hip arthroplasty. Fretting-corrosion initiates when micromotion leads to metal release; however, factors leading to micromotion, such as microgrooves on the stem taper, are not fully understood. The purpose of this study is to describe a finite element analysis technique to determine head-neck contact mechanics and investigate the effect of stem taper microgroove height during head-neck assembly.

  • Dilute Betadine Lavage Reduces the Risk of Acute Postoperative Periprosthetic Joint Infection in Aseptic Revision Total Knee and Hip Arthroplasty: A Randomized Controlled Trial

    The purpose of this randomized, controlled trial is to determine whether dilute betadine lavage compared to normal saline lavage reduces the rate of acute postoperative periprosthetic joint infection (PJI) in aseptic revision total knee (TKA) and hip arthroplasty (THA).

  • Physical Therapy on Postoperative Day Zero Following Total Knee Arthroplasty: A Randomized, Controlled Trial of 394 Patients

    Surgeons have increasingly emphasized early mobilization as a way to facilitate discharge following total knee arthroplasty (TKA). The purpose of this study was to determine whether starting formal physical therapy (PT) the afternoon of postoperative day (POD) 0, instead of starting PT the morning of POD 1, could shorten hospital length of stay (LOS).

  • Total Joint Arthoplasty and Being a Good Antibiotic Steward: My Takeaways from AAOS

    Overall the 2019 AAOS Annual Meeting was a great success in Las Vegas, Nevada. As an Arthroplasty Surgeon, I focused my time on the hip and knee reconstruction sections and I still was unable to see many of the available offerings. There were a tremendous number of clinical papers, scientific exhibits, instructional course lectures and posters (double the number this year, as posters rotated after two days of the meeting). The exhibitors were out in full force with their latest products, a large emphasis was placed on computer navigation, targeting devices, robotic surgery and imageless guidance systems. While all forms of presentation were different, there did seem to be a few common themes, including: opioid use/protocols to limit over-prescribing for hip and knee arthroplasty, spine-pelvis interaction and implications with component placement, infection detection, and goals/techniques to optimize patient outcomes, particularly in the short-stay arena.

  • What Are Hip and Knee Replacement Implants Made Of?

    Hip and knee replacement surgery involve replacing the worn-out bone and cartilage lining your hip or knee joint with new implants that are composed of materials such as ceramic, metal and plastic. The materials used for hip and knee replacements are quite similar.

  • Is it Time for a Joint Replacement?

    Hip or knee joint replacement surgery is considered the last line of treatment for joint pain. For some people, it’s the only way to alleviate arthritis-related pain that significantly affects daily activities, such as walking up and down stairs, putting on shoes and socks, and getting in and out of a car. If you find yourself unable to perform simple tasks after trying more conservative treatments, it may be time to consider a joint replacement.

    To determine if you’re a candidate, most doctors will consider how much you can gain by undergoing the procedure. Your doctor will review your medical history and x-ray the affected joint. If your symptoms are severe and correspond with what is found on the x-ray, your doctor will likely recommend the surgery.

  • Hip and Knee Surgeons Collaborating at Co-Branded Meeting in China

    The 11th Congress of Chinese Association of Orthopaedic Surgeons (CAOS) in Hangzhou, China featured a co-branded program with AAHKS with Richard H. Rothman, MD, PhD and Yan Wang, MD serving as Chairs and Quoqiang Zhang serving as Executive Chair. The program included numerous American and Chinese surgeons discussing a wide array of topics in both a lecture and small panel question and answer format. Specific lectures addressed management of dysplastic hips, perioperative optimization of patients, femoral and acetabular revision principles, biomaterial properties of acetabular components and practice management pearls. The program appeared to be a great success with outstanding discussions amongst the moderators, panel members and attendees.

    The day was filled with stimulating discussions featuring differing opinions amongst the CAOS and AAHKS members. Significant attention was focused on bearing surfaces for total hip arthroplasty, single vs. two-stage procedures for infection and overall management of bony defects in revision hip and knee arthroplasty. It was a wonderful collaboration between the two organizations that culminated in a high-tech opening ceremony, followed by a night out in Hangzhou to witness the Impression West Lake Show.
