[Drilling decompression of the proximal tibia for osteoarthritis of the knee]
Objective:
To investigate the effect of drilling decompression of the proximal tibia for the Osteoarthritis of the Knee.
Method:
The drilling decompression of the proximal tibia were performed in 21 patients (38 knees) of osteoarthritis with 99mTc-MDP scintingraphy and the intraosseous phlebography made pre-postoperatively. Knee function scores and scales were evaluated.
Result:
During 6-12 months follow-up, the preoperative score of the knee function was 18-48 (average 30.78) and the postoperative score was 61-96 (average 87.95); the rates of fair and good of knee scales rose from 5% preoperatively to 86.84% postoperatively.
Conclusion:
Drilling decompression of the proximal tibia is a simple, safe, less traumatic and effective method to relieve the pain and improve the function for the early osteroarthritis of knee, For late cases it is a method to relieve pain. 99mTc-MDP scintingraphy can be used as a method to diagnose the early stage of the osteoarthritis.
