[Bone cement injection into tibial condyle for the prevention of degenerative osteoarthritis].

OBJECTIVE
To observe therapeutic effects of preventing degenerative osteoarthritis by injecting bone cement into tibial condyle.


METHODS
From January 2006 to Junary 2009, 24 patients with degenerative osteoarthritis were treated by injecting bone cement into tibial condyle, including 10 males and 14 females, ranging in age from 46 to 65 years, with an average of 50 years. The mean course of duation was 1 year. HSS scoring system was used to evaluate therapeutic effects preoperatively and one year after follow-up.


RESULTS
All patients were followed up over 2 years. HSS score after two years follow-up was 66.65 +/- 6.30, which was higher than that of preoperative 35.70 +/- 4.80. There was no significant difference between preoperation and one year after follow-up in anatomy angle of tibia.


CONCLUSION
Bone cement injection into tibial condyle can prevent degenerative osteoarthritis and varus knee.
