Authors compare the results of clinical evaluation with X-ray examination and subjective condition of patients with primary osteoarthritis of the hip joint. Clinical evaluation in 18 patients was qualified according to the range of motion of the hip joint to the first point of resistance with passive internal rotation. For the evaluation of the subjective complaints of the patients the algofunctional questionnaire WOMAC was used, morphological findings were evaluated according to Kellgren and Lawrence scale. The results were correlated one another. Statistically significant negative correlation (Rs = -0,550) was found between the WOMAC index and the range of motion of the internal rotation to first resistance. No statistically significant correlation was found between the other results.
