Comparisons of Cytokines, Growth Factors and Clinical Efficacy between Platelet-Rich Plasma and Autologous Conditioned Serum for Knee Osteoarthritis Management.

This study aimed to directly compare the contents and the clinical efficacy of the two autologous blood-derived products, platelet-rich plasma (PRP) and autologous conditioned serum (ACS) for osteoarthritis (OA) treatment. The contents of standard-prepared PRP and ACS prepared at 37 °C for 1 h, 3 h, 6 h, and 24 h from healthy volunteers were compared. The clinical efficacy of pain relief in patients with Stage III knee OA was evaluated by a patient-reported visual analog scale (VAS) pain rating.

Case report: lateral capsular release for acute extension deficit in a child with congenital radioulnar synostosis.

Acute elbow extension deficit is an unusual phenomenon that has been observed in patients with congenital radioulnar synostosis. We report the case of an 11-year-old girl with congenital radioulnar synostosis who developed acute extension deficit of the right elbow and whose elbow range of motion was restored following lateral capsular release.

Traumatic Separation of the Distal Ulnar Physis in Children: A New Classification for Displaced Volar-Flexion Injuries.

Objectives: To propose a new fracture classification according to the direction of epiphysis displacement and to compare clinical findings and surgical outcomes between these subtypes.

Design: Retrospective study.

Setting: A tertiary referral hospital.

Gastrocnemius tightness on joint angle and work of lower extremity during gait.

Background: Muscular tightness is a common clinical musculoskeletal disorder and is regarded as a predisposing factor for muscle injuries. In this study, a two-way mixed design ANOVA was applied to investigate the effects of the gastrocnemius tightness on the joint angle and joint work during walking.

Methods: Twenty-two patients with muscular tightness of gastrocnemius muscle (<12 degrees of ankle dorsiflexion with knee extended) and 22 age- and gender-matched subjects with normal gastrocnemius flexibility (>15 degrees of ankle dorsiflexion with knee extended) participated in this study.

Posteromedial dislocation of the elbow with lateral condyle fracture in children.

Posteromedial dislocation of the elbow with lateral condyle fracture is a rare injury, and only a few cases have been reported in the literature. We report 3 children who had posteromedial dislocation of the elbow with Milch type II lateral condylar fracture of the distal humerus. Major complications included malunion, nonunion of the fracture, heterotophic calcification and elbow subluxation.
