title: [Effects of warm needling moxibustion on knee cartilage and morphology in rats with knee osteoarthritis].
abstract: OBJECTIVE
  To observe the effects of warm needling moxibustion on body mass, knee cartilage andmorphology in rats with knee osteoarthritis (KOA).
  
  
  METHODS
  Forty SD rats were randomly divided into a normalgroup, a model group, a medication group and a warm needling group, 10 rats in each one. Except the normalgroup, the rats in the remaining three groups were injected with papain to establish the model of KOA. After themodeling, rats in the model group did not receive any treatment; rats in the warm needling group were treated withwarm needling moxibustion at bilateral "Xiqian"; rats in the medication group were treated with intragastric administration of meloxicam; rats in the normal group were treated with 0. 9% NaCl solution (identical dose as medication group) and immobilized as the warm needling group. The treatment was given once a day for consecutive20 days. The body mass, scale of knee cartilage and morphological changes were observed in each group after'treatment.
  
  
  RESULTS
  The increasing of body mass in the medication group and warm needling group was faster than!that in the model group, but slower than that in the normal group (all P<0. 05); the difference between medication group and warm needling group was not statistically significant (P>0. 05). The scale of knee cartilage in thewarm needling group and medication group was significantly lower than that in the model group (both P<0. 05),while the scale in the warm needling group was lower than that in the medication group (P<. 05). Regarding theknee morphology under micro-CT, the relief of knee degeneration and improvement of knee recovery in the warm needlinggroup were superior to those in the medication group.
  
  
  CONCLUSIONS
  The warm needling moxibustion could effectively reduce the knee pain, improve the recovery of knee cartilage, which is a safe and effective treatment.
