We examined the in vivo alterations of human patellar bone blood flow that occur with surgical dissection of the extensor mechanism during total knee arthroplasty. A laser doppler probe was used to measure central patellar blood flow at baseline after quadriceps tenotomy, after partial fat pad excision, after lateral release, and after completion of the lateral release with superolateral geniculate sacrifice. The initial quadriceps tenotomy and medial arthrotomy decreased patellar vascularity to 60.4% of baseline. Fat pad resection initiated another 10.4% decline. The lateral release resulted in a patellar vascularity that was 43.6% of baseline. Finally, the loss of superolateral geniculate inflow reduced the patellar flow to 30.61% of baseline.
我们研究了全膝关节置换术中伸肌机制手术解剖时发生的人髌骨关节血流的体内变化。使用激光多普勒探头在股四头肌肌腱切断术后、部分脂肪垫切除术后、外侧松解术后以及外侧松解并牺牲膝上外侧动脉完成术后测量髌骨中央血流。最初的股四头肌肌腱切断术和内侧关节切开术使髌骨血管化降至基线的60.4%。脂肪垫切除又导致了10.4%的下降。外侧松解导致髌骨血管化降至基线的43.6%。最后，膝上外侧动脉血流丧失使髌骨血流降至基线的30.61%。
