Abstract:

BACKGROUND: In recent years, all kinds of absorbable internal fixation materials have been used in the clinical treatment of patellar transverse fractures.
OBJECTIVE: To investigate the repairing effect of absorbable internal fixation materials on patellar transverse fractures.
METHODS: Totally 102 cases of fresh patellar transverse fractures were included 62 males and 40 females cases, with a mean age of (41.85±11.15) years, and according to treatment methods, they were divided into two groups: observation group (n=52) using absorbable screws for reconstruction and control group (n=50) using Kirschner wire repair. At 12 months after repair, Lysholm knee function score were measured and evaluated, and the occurrence of adverse events was recorded.
RESULTS AND CONCLUSION: The knee function score and excellent rate of the observation group were significantly higher than those of the control group (both P < 0.05). In the observation group, there were four cases of fracture displacement, but no skin irritation and other adverse events occurred; in the control group, there were two cases of nonunion and five cases of skin irritation or internal fixation loosening and slippage. Therefore, there was a higher incidence of adverse events in the control group compared with the observation group (P < 0.05). These experimental results show that the use of absorbable screws in the repair of patellar transverse fracture can promote the functional recovery of the knee joint, with good biocompatibility.
