Mixing implants of differing metallic composition in the treatment of upper-extremity fractures.

abstract：:Pain is the predominant symptom of degenerative knee arthritis and the main reason patients undergo total knee arthroplasty (TKA). Variation in patient response to pain has proved difficult to quantify. The effect of removing pain by testing TKA patients' range of motion (ROM) before and after the administration of an...

abstract：:Instability is one of the most common causes of failure of total knee arthroplasty (TKA). The presentation can vary from pain to frank dislocation with the etiologies just as varied. Instability after TKA can be classified by where the instability occurs in the knee's arc of motion as well as the chronicity of the pro...
