Due to the extension of life expectancy, the number of elderly people increases, and thus the number of disease and injuries of the locomotor system, especially the hip joint. One of the persistent trend is an increasing trend in the number of patients with coxarthrosis and implanted total hip endoprosthesis. One of the postoperative complications that occurred after implantation a total hip endoprosthesis is heterotopic ossification (HO). HO is the most common complication that occurs after the implantation a total hip endoprosthesis with recorded cases in the range of 9-90%. HO are insufficiently understood phenomenon, which is characterized by the formation of bone in periarticular tissues. We prospectively followed patients who implanted total hip endoprostheses in the department of orthopedics ZC in Kos. Mitrovica in 2008. and 2009. year. We examined the influence of physical agents on the prevention of HO near the hip joint. In these patients the treatment was carried out kinesiotherapeutic at the Center for Rehabilitation Health Center Kosovska Mitrovica, as well as pulse therapy low frequency magnetic field frequency of 30 Hz, 30 minutes, 8 mT intensity and 15 minutes interferential current, 0-100 Hz frequency. All patients were on the rehabilitation of one month (20 days). Based on this research we confirmed the assumption that the use of low frequency pulsed magnetic fields, interference currents and kinesitherapy prevents HO in patients after implantation of total endoprosthesis of the hip joint.

Arthrosis (A) are the degenerative-dystrophic disease of the peripheral ankles. Etiology is unknown. The genetic factor and external factors, mostly of a mechanical nature are the crucial ones, however, in the literature more emphasis is put on the infection factor and participation of immunity in the etiology of the patogenesis A. We have treated 42 patients sicked of the gonarthrosis. A majority of them is not , as expected, is in their old age, but between 40-50 old. Out of total number, 12 % has had symptoms of early sinovitis while 17% has had symptoms of reactive synovitis. Early sinovitis is characterized in lymphocytes and plasmocytes, rare neutrophils with no fibrile layers. Reactive (later) sinovitis is characterized by rare neutrophils, crystals of appatite and abundant detritus. It is most probably that an early synovitis has an immunological and later one reactive character.

Gonarthrosis is degenarative knee disease as well as the commonest chronic knee arthropaty. Nowadays more attention is given to modern pathogenesis of arthrosis in two levels: 1. immunological; 2. some ferments disbalance phenomenon. In the second level of pathogenesis, a special atention is given to metalloprotheasis. The importance of doxycyclin on the reduction of metalloprotheasis in synovia has a great therapy importance not only theoretically but pratically as well 78 patients with primary and secundary gonarthrosis has been examined (19 men and 59 women) the appliance of doxycyclin in clinic elements common for gonarthrosis caused the improvemnt of all clinic parameters especially muscular strenght and pain, but the largest improvement was noticed in knee - joint circumference

Gonarthrosis is the most frequent artropathy of knee.The second joint of frequency and localisation osteorthrosis after joint of haunch. In complexive therapy of gonarthrosis, exept the medical therapy, important place has physical therapy
or special laser-therapy. 78 patients, where tested with a primary and secondary gonarthrosis, 19 men, and 59 women. They were all hospitalised on Rheumatology department of Internal Clinic of Clinical and Hospital Centre in Pri{tina. By objective using of parameters we show that, laser is a very important modern expedient on clinical results for gonarthrosis (volume of joint, volume of movements, muscle strength, and on the first pain, pain in static positions, pain in moving and night pain). It is seen that all values got by laserotherapy are statistically high significiant. During the use, of laserotherapy, the medical therapy was included.
