Diagnostic Performance of Ultrasound to Evaluate Mild Hip Osteoarthritis: Comparison With Radiography and MRI

Journal of Clinical Ultrasound, EarlyView.
A moderate‐sized femoral neck osteophyte (white arrow) in US (A), anteroposterior CR (B), and MRI (C). Additional osteoarthritis‐related changes (arrowheads) are visible in CR and MR, but not in US. US and CR demonstrated similar moderate diagnostic capability to detect mild hip osteoarthritis and were associated with increased hip pain.

Advanced Testing Protocols Simulate Failures and Validate Antioxidant Polyethylene in Ankle Implants

Journal of Orthopaedic Research, EarlyView.
Abstract Total ankle replacement (TAR) has become an effective treatment for end‐stage ankle osteoarthritis. Multiple factors, including patient characteristics, surgical technique, alignment, and bearing surfaces, influence TAR survivorship. Polyethylene (PE) fatigue is a key consideration in improving outcomes.

Cemented Total Hip Replacement Arthroplasty [PDF]

Hip & Pelvis, 2010
시멘트 인공 고관절 전치환술은 1960년대부터 처음 사 용 되기 시작하였으나 1990년대까지는 시멘트 고정의 실 패로 인한 주위의 골 용해가 인공 고관절의 실패의 원인으 로 생각되어 무시멘트형의 인공 관절이 많이 개발되었다. 하지만 그 후 폴리에틸렌 마모 편으로 인하여 골 용해가 발생한다는 것이 밝혀지고 무시멘트형의 인공 고관절 치 환술 후 골 용해가 더 심하게 발생하고 시멘트 기법 및 인 공 관절의 재질, 디자인 등의 개선으로 인하여 최근에 시 멘트형의 대퇴 주대의 사용이 빈번해 지기 시작하였다. 또한 국내에는 비구측에 시멘트를 사용한 폴리에틸렌 컵 의 사용이 거의 없으나 최근 재치환술을 요하는 환자가 많 아지고 골 다공증이

In Vitro Evaluation of Hemiarthroplasty Bearing Materials: A Scoping Review (Part I)

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Hemiarthroplasty is used to treat joint damage confined to one side, aiming to preserve the remaining healthy cartilage and bone while addressing conditions like femur fractures and osteonecrosis; however, challenges persist due to cartilage wear and inconsistent clinical outcomes.

Laser Disinfection Acts as Biofilm‐Disrupter in Periprosthetic Joint Infection (PJI)

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Infections after joint arthroplasties represent a devastating and progressively escalating complication with increased morbidity and mortality. The eradication of biofilms from infected implants is still an unsolved challenge. The erbium‐doped yttrium aluminum garnet (Er:YAG) laser, which delivers high‐energy light for rapid tissue ablation ...

Dual-mobility socket in challenging total hip arthroplasty : 2-6 years follow-up. [PDF]

, 2018
The success of dual-mobility sockets in achieving implant stability in primary hip replacement is already well established. However, stability cannot always be achieved, especially when dealing with more difficult indications.

Influence of cementless hip stems on femoral cortical strain pattern depending on their extent of porous coating [PDF]

, 2012
The extent of porous coating of cementless total hip stems is held responsible for radiological periprosthetic changes, the rate of thigh pain, and even its long-term success.
