[The change of intraosseous pressure in the femur and tibia near knee and knee pain].
The intraosseous pressure (IP) in the femur and tibia near knee of 21 patients with pain of knee region was measured and the arthroscopic examination of their knee joints was performed in past 3 years. The IP of femoral and tibial condyles in these 21 patients were averaged 0.143 +/- 0.011 kPa and 0.180 +/- 0.022 kPa, respectively. There were 16 patients (76.19%) whose IP of femoral condyle was higher than normal value (0.130 +/- 0.024 kPa, P < 0.01) and 18 patients (85.7%) whose IP of tibial condyle was higher than normal (0.105 +/- 0.25 kPa, P < 0.01). The average intracapsular pressure of the knee of 21 patients was 0.135 +/- 0.35 kPa and in 18 of them (85.7%) it was higher than the normal value (0.120 +/- 0.020 kPa, P < 0.01). The results show that increase of IP of the femur and tibia is the cause of pain and pathologic changes of the knee joint. The effect of the change of IP on physiology and pathology of the femur and tibia, the idiopathic intraosseous hypertension at the knee region, the different change of IP in various conditions of the knee, and the treatment and its improvement were discussed.
