| 中文摘要:本文应用电测法,对6例人体新鲜髌骨进行测试,研究髌骨随不同膝关节屈曲角度的应力变化,以及某些特定屈曲角度下股四头肌拉力对髌骨应力的影响。结果显示：在恒定的股四头肌拉力作用下,当屈膝角度在0～40°范围内增加时,髌骨应力增长缓慢,而当屈膝角度在40～90°范围内增加时,髌骨应力显著增加。因此在骨伤临床康复中应充分重视屈膝角度对髌骨应力的影响,尤其当屈膝角超过40°时,髌骨应力迅速增大这一事实,对髌骨骨折病人固定术后不负重或负重膝关节屈伸活动范围的掌握,具有一定的意义。 |

| The Effcet of Various Flexion Angles of Knee Joint on the Stress of Patella-a Biomechanical Research |
|
| ABSTRACT The variation of patterns of patella stress under different flexion angles of knee joint and the effect of quadriceps force on patella stress under specified flexion angle were measured electrically on 6 fresh patellas of cadavers.The results demonstrated that under a conslant quadriceps force, the strain of patella increased slowly as the flexion angles increasing from 0° to 40°,and the strain inceased significantly as the flexion angles increasing from 40°to 90°. It was suggested that,especially as the flexion angle is over 40°,the effect of flexion angle of knee joint on the stress of patella should be taken into full consideration,for postoperative unburdened as well as burdened exercise of knee joint. |
