[Current situation of surgical treatment of inferior polar fracture of patella].

OBJECTIVE

To investigate the advance in surgical treatment of inferior pole fracture of patella and to explore the existing problems and further research directions.

METHODS

Domestic and foreign literature in recent years on patella fracture was extensively reviewed, the surgical treatment of inferior pole fracture of patella was summarized by combining the research findings with clinical experience.

RESULTS

The surgical treatment of inferior pole of patella fractures included retaining the integrity of the patella and partial patellectomy of inferior pole of patella and extending knee installation reconstruction. There were kinds of ways to retain the integrity of the patella, such as circular wire fixation, tension band fixation, NiTi-patella concentrator fixation, basket plate fixation, reforming McLaughlin way and polydioxanone suture net fixation; the latter category is partial patellectomy and extensor device reconstruction. Every surgical way had its advantages and limitations.

CONCLUSION

Most studies tend to retain the integrity of the patella, but some researches have shown that partial resection of inferior pole of patella had no significant effect on knee function. It is important to obtain the security excisional range and elongation range postoperative by experiment for regulating the treatment of comminuted fractures of inferior pole of patella.
