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...

    Background: Malnutrition has been linked to poor outcomes after elective joint arthroplasty, but the risk of unplanned postoperative intensive care unit (ICU) admission in malnourished arthroplasty patients is unknown. Methods: 1098 patients were followed as part of a prospective risk stratification program at a tertiary, high-volume arthroplasty center. Chronic malnutrition was defined as ...

The temporomandibular joint (TMJ) is the most active, functioning joint of the body. Limitations of the mouth opening and deformity of the lower jaw can be caused by bony or fibrous ankylosis of the TMJ due to various reasons and mostly is due to fusion of the condyle to the base of the skull. Trauma to the TMJ is the most common etiology of ankylosis of TMJ. Clinical examination, radiographic ...

Gap arthroplasty (GA) and interpositional arthroplasty (IA) are widely used for the treatment of temporomandibular joint ankylosis (TMJA). However, controversy remains as to whether IA is superior to GA. PubMed, EMBASE, the Cochrane Library, the Web of science and the China National Knowledge Infrastructure were searched for literature regarding these procedures (published from 1946 to July 28,...

INTRODUCTION: Proper bone cut and soft tissue balancing are the most critical procedures in total knee arthroplasty (TKA). A gap balancing technique is commonly used in TKA to create an equal extension and flexion gap. However, obtaining a flexion gap sufficiently large for the extension gap in cruciate retaining (CR) TKA is sometimes difficult and the flexion gap in CR TKA tends to be smaller ...

Treatment of the posterior cruciate ligament (PCL) is a matter of continued controversy in total knee arthroplasty. By using so-called cruciate ligament-substituting implant designs, retention and resection of the PCL produce equivalent clinical results. However, it remains unclear whether primary resection of the PCL leads to relevant instabilities of the flexion gap. Especially when the incre...
