Therapeutic effect of bone decompression needle on the knee osteoarthritis in rabbit

Objective: Osteoarthritis is a progressive disease of the joints which often cause increased intraosseous pressure in the tibia bones and reduced blood flow. Bone decompression needle is a newly developed osteoarthritis treatment device.

Methods: To investigate the effectiveness of bone decompression needle on osteoarthritis, we constructed an osteoarthritis model with Japan white rabbits, and used bone decompression needle for decompression treatment.

Results: It showed that the decompression treatment reduced the intraosseous pressure in tibia bones. In hemorheology measurement, the decompression also dropped all the hemorheology indexed including whole blood viscosity, plasma viscosity, hematocrit, and erythrocyte sedimentation rate, therefore the blood flow was greatly increased. We also showed that two needle decompression treatments could almost bring all these indicators back to the level as in the normal condition.

Conclusion: Therefore the decompression with bone decompression needle has clear protection and therapeutic effect on knee osteoarthritis.
