In vivo kinematic evaluation of total hip arthroplasty during stair climbing

Alterations in lower limb multimuscle activation patterns during stair climbing in female total knee arthroplasty patients.

Total knee arthroplasty (TKA) patients commonly experience neuromuscular adaptations that may affect stair climbing competence. This study identified multimuscle pattern (MMP) changes in postoperative female TKA patients during stair climbing with a support vector machine (SVM). It was hypothesized that TKA patients adopt temporal and spectral muscle activation characteristics indicative of mus...

Knee and hip kinetics during normal stair climbing.

Understanding joint kinetics during activities of daily living furthers our understanding of the factors involved in joint pathology and the effects of treatment. In this study, we examined hip and knee joint kinetics during stair climbing in 35 young healthy subjects using a subject-specific knee model to estimate bone-on-bone tibiofemoral and patello-femoral joint contact forces. The net knee...

The Relationship between Clinical Measures and Stair Climbing Biomechanics in Patients with Total Knee Arthroplasty

Total knee arthroplasty (TKA) is a generally successful surgical procedure to treat end-stage knee osteoarthritis; however, suboptimal outcomes, including difficulty stair climbing, do occur [1]. Clinicians use the stair climbing test (SCT) to track functional status, where a patient ascends and descends a flight of stairs as fast as possible and a faster time suggests better function and incre...

Transfusion-Transmitted Babesiosis During Total Hip Arthroplasty.

Babesiosis is a potentially life-threatening zoonotic disease that is endemic to the northeastern United States and increasing in prevalence worldwide. Transmitted by the same Ixodes tick responsible for Lyme disease, the intraerythrocytic parasite Babesia causes a wide range of clinical presentations--from asymptomatic carriage to a fulminant course with rapid deterioration. Symptoms typically...
