title: [Effects of needle knife relaxing therapy on tension of local soft tissue and pain of osteoarthritis of knee].
abstract: OBJECTIVE
  To probe into the mechanism and methods of needle knife relaxing therapy for treatment of osteoarthritis of knee from biomechanical view.
  
  
  METHODS
  Needle knife relaxing therapy was given to 92 pain points around the knee joint in 14 cases of osteoarthritis of knee, and the displacement of the local pain point under the stress of 500 g (L500 g) was measured and the VAS scores were recorded before and after treatment.
  
  
  RESULTS
  L500 g of the pain point was (4.72+/-1.03) mm before treatment and (5.39+/-1.01) mm after treatment with a very significant difference before and after treatment (P<0.01), and VAS score was (7.10+/-1.49) points before treatment and (1.49+/-1.24) points after treatment with a very significant difference before and after treatment (P<0.01), and there was a linear correlation between the changes of L500 g and VAS scores.
  
  
  CONCLUSIONS
  There was close connection between the local pain and tension of local soft tissue in knee osteoarthritis. The needle knife relaxing therapy can relieve the neurovascular compression or traction syndrome by relaxing the local contracted, adhesive soft tissue, so as to relieve tension pain and finally recover internal force equilibrium of the knee joint.
