However, the analysis of muscle fatigue by the etc behavior of the root mean square and median frequency of the myoelectric signal in the elderly is still quite scarce in the literature, highlighting the findings of this study and encouraging further research in this area. CONCLUSION Mean values of the sample point to a group with high body fat, high expression of fatigue and functionality of lower limbs similar to published studies. The objective measurements of muscle strength and fatigue were not associated with subjective variables of joint function (WOMAC), but with those related to pain in patients with osteoarthritis of the knee. Moreover, the values assigned to this scale and some domains of the WOMAC also correlated positively.

Pain intensity is correlated with functional disability of older individuals with knee OA and a more significant event of signs of fatigue, checked the behavior of the median frequency of the EMG signal.

The knee is one of the most important weight-bearing joints and it is often subjected to trauma due to its location in the body. 1 , 2 Tibial plateau fractures occur often among knee fractures. The aim in the treatment of tibial plateau fractures is to obtain a stable, pain-free and fully functioning knee. 1 , 2 Despite the various treatment options available, either by external or internal methods, the treatment of comminuted tibial plateau fractures often yield to unsatisfactory results, related to prolonged immobilization and development of osteoarthritic changes.

In this study we present our clinical and radiological results and our surgical technique as a closed reduction, percutaneous cannulated screw fixation and hexapodal external fixator the treatment of tibial plateau fractures in three patients. PATIENTS AND METHODS Between 2009 and 2010, the treatment of three male patients (mean age 47 years old; range 39 to 61 years) with comminuted tibial plateau fractures was performed under fluoroscopy control. Closed reduction was performed by using a Kirschner wire as a joystick and a periostal elevator. Then, the major fragments were fixed using a headless cannulated screw to obtain rigid fixation of the proximal tibial articular surface.

The continuity of the stabilization between the articular surface and the tibial diaphysis was then obtained by application of a hexapodal external fixator (Smart Gotham, New Jersey, USA). (Figure 1) None of the patients had any vascular or neural lesions at the time of admittance. One of the patients exhibited ipsilateral quadriceps atrophy Batimastat related to a previous anterior cruciate ligament injury. The remaining two patients did not have any lower extremity alignment problems, nor intraarticular pathologies including meniscal tear, chondral lesion, or ligament injury.
