Treatment of patella fracture under arthroscope / 中国微创外科杂志

ABSTRACT

Objective To study the efficacy of arthroscopy in the management of patella fracture.Methods Arthroscopic techniques were employed for treating 42 patients with fresh simple patella fracture.After blood clots and fragments were cleaned up,the fracture was reduced by manipulation.Two Kirschner's pins were parallelly inserted percutaneously for internal fixation of the fracture.Then a modified tension band fixation with percutaneous wire interposition was made.Results The operation time was(1.2~3) hours(mean,2.2 hours).The time to bone union was 7~10 weeks(mean,7.5 weeks).The postoperative hospital stay was 7~14 days(mean,8.5 days).Follow-up checkups in 37 patients for 6 months ~ 4 years(mean,19.2 months) revealed bone union in all the patients and no joint instability or traumatic arthritis.The curative results were classified as excellent in 34 patients,good in 2 patients,and fair in 1,the rate of excellent or good results being 97.3%(36/37).Conclusions Arthroscopic management of patella fracture has advantages of accurate reduction and fixation,little invasion,early postoperative functional training,and quick recovery.
