Comparative StudyEffects of two different continuous passive motion protocols on the functional activities of total knee arthroplasty inpatients.
The aim of this study was to compare the effects of two different continuous passive motion (CPM) application protocols (low- and high-angle) on the early phase functional activities of total knee arthroplasty inpatients. ⋯ Although low-angle CPM application produced better results in terms of gait speed following TKA, the high-angle CPM application was superior in terms of independence levels of functional activities in the early postsurgery period. This result suggests that the appropriate use of rehabilitation methods such as CPM applications may guide clinicians to increase patients' level of independence.

Effect of platelet-rich plasma for treatment of Achilles tendons in free-moving rats after surgical incision and treatment.
The purpose of this study is to investigate, both histopathologically and biomechanically, the effect of platelet-rich plasma (PRP) on surgically repaired Achilles tendon rupture recovery in rats. ⋯ It is thought that PRP use in Achilles tendon ruptures positively affects histopathological recovery in the early period, but that it does not produce the same biomechanical effect. We believe that PRP use for qualified tendon recovery is histopathologically beneficial.

A new small-animal model for the study of acquired heterotopic ossification after hip surgery.
Heterotopic ossification (HO)--the formation of bone in soft tissues--is a frequent problem after surgery of the hip and pelvis, but little is known about its underlying pathogenic mechanisms. It is vital to study the underlying pathogenesis in animal models to develop and evaluate new prophylactic regimens directed against HO. However, previously developed small-animal models for the study of HO imitate neither surgery nor trauma-mechanisms that potentially cause HO. Hence, the goal of this study was to develop a novel small-animal model imitating hip surgery that can reliably produce HO. ⋯ A rat model of hip/pelvic surgery that does not use exogenous osteogenic stimulus and can reliably produce HO was developed.
