2·Objective To explore the optimum indications of different fixative methods in the treatment of patellar fracture.
目的探讨不同方法治疗髌骨折的最佳适应证。
3·Patella resurfacing has no effect on the reduction of patellar tendon.
置换髌骨对髌腱短缩没有影响。
4·Patella resurfacing has no effect on the shortening of patellar tendon.
置换髌骨对髌腱短缩没有影响。
5·Objective: to analyse the biomechanics element of Nitinol patellar Connector which is distinctive in treating comminuted patellar fractures.
目的：分析镍钛聚髌器治疗粉碎性髌骨骨折，促进骨折愈合的生物力学基础。
