本實驗的目的,是以X-光透視法(Flouroscopy)記錄人體髕─股骨間關節在矢狀面之運動情形,希望藉由幾何方法推算連接髕骨兩端之Quadriceps Tendon(TR)、Patellar tendon(TP)以及髕─股骨間關節作用力(PFJR)三者力量大小的關係,以及膝關節力臂長度隨膝蓋彎曲之變化情形。 12位平均年齡21歲之正常青年分成兩組受測,各以不同的姿勢活動膝關節,再同步以X-光透視法做連續性矢狀面攝影;所得畫面經VCR及影像數位化系統轉換為數位座標值模式進行幾何運算。 二組實驗結果均?實Quadriceps tendon與Patellar tendon在膝關節伸曲過程中張力並不相等,且二者大小的比值(TR/TP)亦隨著膝關節彎曲角度改變而改變。此一結果顯示以平衡樑(balance-beam)的模式取代無磨擦滑輪的假設來描述髕骨活動機轉將更為貼切。
The objective of this study is to understand the patella-femoral joint mechanism through a two dimensional biomechanical model. We used a real-time digital X-ray video-fluoroscopic system to record the knee motion in the sagittal plane. The picture sampling frequency was 60 frames/sec. In the analysis, the ratio between the forces in the quadriceps tendon (TR) and the patellar tendon (TP) at different flexion-extension angles of the knee were calculated by the geometric method. 12 healthy young men were measured during simulation of two knee functions: stair ascent and leg raise. Using a real-time video-fluoroscope and VCR system, the continuous movement of the patello-femoral joint was recorded, and the digital data were analyzed with PC/AT. We found that TR was not equal to TP as several researchers had reported before. Furthermore, the ratio TR/TP was changed as a function of flexion angle, and the difference between TR and TP affected both the magnitude and direction of the patella-femoral joint reaction force (PFJR). So we concluded that the concept of the patella-femoral joint acting as a "balance beam" is better than "pulley"!
