We measured the intraarticular pressure in 10 knees during knee arthroscopic surgery. The average intraarticular pressure found in cases with bleeding was 53.7mmHg. When we studied the relationship between the Knee flexion angle and intraarticular pressure, we found that the minimum intrrarticular pressure occurred at 30° of knee flexion in all cases.

Sternal fractures without external injury are exceedingly rare.A 79-yr-old woman has been troubled with ‘asthma’ which she appeared to be wheezing and having a cough since her mid fifties.A bulging of the center part to the sternum was noted without external injury on arising the morning on January 18, 1989.An X-ray film showed a sternal fracture and blood chemistry results did not indicate a malignant tumor.We suggested that weakness of the sternum by osteoporosis, the transmission of forces to the sternum by compression vertebral fracture and chronic pressure to the thorax with ‘asthma’ were important factors in the onset of a non-traumatic sternal fracture.

Accelerometric measurement of gait ananlysis is a simple, inexpensive and effective way to evaluate gait and was first introduced by Liberson and colleagues. Smidt applied accelerometry to the normal and abnormal patterns of gait. Ogata used accelerometry to quantitatively vevaluate the lateral thrust of the knee and investigated the dynamic effects of a wedged insole on the thrust of OA knees.In the present study, we used an accelerometer, strain gauge and goniometer to inveshgate the effects of accelerometry on heel strike in gait analysis. The acceleration placed on the calcaneal region on heel strike appeared faster than any other measurement. Our results suggest that an accelerometer placed on the calcaneal region provides the most useful information on the exact moment when the heel strikes the ground.
