BACKGROUND Traditionally, the results of revision total knee arthroplasty have been determined with use of surgeon-based measures such as the Knee Society rating system. Recently, outcome and quality-of-life measures have shifted toward a greater emphasis on patient-based evaluation. The aim of our study was to determine the validity and responsiveness of the Knee Society rating system compared...

Popliteal artery occlusion after total knee arthroplasty is rare (0.03-0.17%) but can lead to amputation if overlooked. We should carefully assess vascular patency by Doppler ultrasound and ankle brachial pressure index (ABPI) measurement before and after total knee arthroplasty (TKA) operation.

Background: Although it has been shown that perioperative protocols enhance arthroplasty care and safety, it isnot known how prevalent their use is in safety net hospitals, which operate with a mandate to treat the poor andunderserved. Understanding the elements currently included in standard perioperative arthroplasty protocols at variousinstitutions may help guide future interventions and pol...

PURPOSE We aimed to evaluate the nationwide incidence and risk factors for symptomatic deep vein thrombosis (DVT) after major lower limb orthopedic surgeries. MATERIALS AND METHODS The Korean Health Insurance Review and Assessment Service database was used to retrospectively identify International Classification of Disease-10 codes for DVT and operation codes representing hip arthroplasty, kn...

BACKGROUND Active patients with arthritic malalignment of the knee are difficult to manage. Arthroplasty, unicompartmental or total knee replacement, may not be appropriate in patients who desire to remain highly active. High tibial osteotomy has been recommended for the treatment of varus osteoarthritis to decrease pressure on the damaged medial compartment. PURPOSE To determine the length o...

A 64 year old white male patient was referred to our infectious disease office with persistent and worsening left knee swelling for the past year. Seven years ago he underwent left total knee arthroplasty. Seven months ago he underwent root canal procedure on his left lower molars. He was not on any antimicrobial prophylaxis for this procedure. Few days after the procedure he noticed that the l...

The purpose of this study was to summarize the literature describing patient outcomes following unicompartmental and bicompartmental knee arthroplasty. Original studies were included in this meta-analysis if they enrolled 10 or more patients at the time of an initial knee arthroplasty and measured patient outcomes using a global knee rating scale. Forty-six studies on unicompartmental prosthese...

Radiological evidence of post-traumatic osteoarthritis (PTOA) after fracture of the tibial plateau is common but end-stage arthritis which requires total knee arthroplasty is much rarer. The aim of this study was to examine the indications for, and outcomes of, total knee arthroplasty after fracture of the tibial plateau and to compare this with an age and gender-matched cohort of TKAs carried ...
