Short-term efficacy and safety of hyaluronic acid injection for plantar fasciopathy.

Purpose: Plantar fasciopathy is the most common cause of plantar heel pain and is considered to be a type of enthesopathy. The short-term efficacy, safety, and dose-response relationship of high-molecular-weight hyaluronic acid (HA) was investigated in patients with plantar fasciopathy.

Methods: In this multicenter, prospective, randomized, double-blind, placebo-controlled trial, 168 patients with persistent pain from plantar fasciopathy for more than 12 weeks were randomly assigned to receive 2.

Distal femoral cut perpendicular to the mechanical axis may induce varus instability in flexion in medial osteoarthritic knees with varus deformity in total knee arthroplasty: a pitfall of the navigation system.

Two factors that influence the external rotation angle of the femoral rotational axis in total knee arthroplasty (TKA) were assessed in 40 medial osteoarthritic knees with varus deformity. First, the anatomic configuration of the femur was assessed using standardized radiographs of the patients' lower extremities before TKA. Second, the degree of medial soft tissue release was assessed during TKA.

Distance of the femorotibial joint gap can be controlled in the modified ligament dependent cut procedure during total knee arthroplasty.

During total knee arthroplasty in fifty consecutive cases, the distal femur and proximal tibia were initially cut. After posterior cruciate ligament excision, the femorotibial joint was expanded by a Tensor/balancer device with 30 inch-pounds of torque (in.lbs) both in extension and flexion, and ligament balancing was obtained in full extension.
