摘要
用12只成年犬的21个髌股关节进行三组动物实验:A组为髌骨全切除,B组为髌韧带缩短,造成髌骨下移,C组为髌骨关节面中央造成斜行的软骨缺损。结果显示三组均有不同程度的关节软骨退变,C组为轻。另以新鲜尸体无病变的膝关节,按照Goodfellow法进行髌股关节接触面检测。结果显示髌韧带缩短组之接触面完全错格,接触面积也较正常者减少44.9%。作者认为髌骨骨折的治疗原则必须是充分恢复髌骨的功能。
Based on the clinical analysis,experimental studies were performed using 12 dogs (21 knees) and 3 fresh cadavers.Dogs were divided into three groups:Group A, total patellectomy;group B,shortening of the patellar tendon and group C,local resection of the articular surface of patella.Histological study showed that osteo- arthritis occured in all of these three groups,but the severity differed greatly and increased with lapse of time. Examination of contact areas of P-F joint according to Goodfellow's method were performed on fresh young cadaver specimens.The authors discovered that on right side which the patellar tendon was shortened,the contact areas of P-F joint were much smaller than that of the normal side,and decreased with increasing degrees of flexion,resulting in an inversed ratio between the contact area and stress. The conclusion is that reestablishment of the function of patella should be set down as the principle of the management of patellar fracture,and osteosynthesis must be the first choice for any kind of comminuted fracture of patella.
