Observational model: CASE_CONTROL
Time perspective: RETROSPECTIVE
Sampling method: NON_PROBABILITY_SAMPLE
Study population: Among them, 19 were males and 22 were females, with an average age of 56.7 years (22 to 79 years)

Brief summary: Research purposes:

Analyze the curative effect of the new tension band system composed of φ3.0mm hollow nails, titanium cables and new gaskets and the patellar tension reduction band in the treatment of lower pole fractures of the patella.

research method: A retrospective study of 41 cases of comminuted fractures of the lower pole of the patella treated with a new tension band system composed of φ3.0mm hollow nails, titanium cables and new spacers from March 2012 to July 2017, including 19 males and 22 females , The average age is 56.7 years (22 to 79 years), 24 cases of AO/OTA A1 type, and 17 cases of C1.3 type. During the same period, 22 cases of comminuted fractures of the lower pole of the patella were treated with a patella tension band, including 8 males and 14 females, with an average age of 57.4 years (32 to 84 years), 17 cases of AO/OTA type A1, and 5 cases of type C1.3. The injury mechanism is all slipping and kneeling injuries.
