Before operation and 3 months after operation, the knee joint function of two groups of patients was evaluated respectively;3 d after operation, enzyme-linked immunosorbent assay (ELISA) was used to detect serum pain mediators, stress hormones and other trauma-related indicators.Results:Differences in the knee joint function index levels were not statistically significant between two groups of patients before operation (P>0.05);3 months after operation, the maximal knee joint flexibility and maximal extension levels of arthroscopic surgery group were higher than those of open surgery group (P<0.05);3 d after operation, serum prostaglandin (PGI2), dopamine (DA), neuropeptide Y (NPY), substance P (SP), glucocorticoid (Cor), renin (R), angiotensin 1 (Ang1), angiotensin 2 (Ang2), epinephrine (E), norepinephrine (NE) and aldosterone (ALD) levels of arthroscopic surgery group were significantly lower than those of open surgery group (P<0.05).Conclusions:Arthroscopic headless compression screw fixation can optimize the knee joint function and reduce the surgical trauma in patients with patellar transverse fracture.展开更多
