Comparing the accuracy of high tibial osteotomies between computer navigation and conventional methods.

Background: The accuracy of correction has been shown to be an important determinant in long-term outcomes of patients who were treated with a medial open-wedge high tibial osteotomy (HTO) who suffer from unicompartmental osteoarthritis (OA). Computer navigation systems have the potential to improve surgical precision. The purpose of this study was to compare radiographic outcomes between patients treated with a navigation system and those treated through conventional methods of assessing alignment intra-operatively.

The value of physical examination in conjunction with a survey for identifying youth pitchers with arm pain.

Objective: The purpose of this study is to evaluate the effectiveness of a screening survey in identifying injuries in youth baseball pitchers. It is hypothesized that a standalone survey is unlikely to give a complete picture and that an additional physical examination is necessary to identify all injuries.

Methods: Seventy-seven youth baseball players who pitched in the last 12 months completed the survey.
