Table 4 Statistical analysis shows significant risk local adjuvants used (p 0.015), the use of liquid nitrogen (p 0.025) and the extension of subchondral bone involvement in lower limb (p 0.007); while stage (p 0.058), status of the physis (p 0.787) nor extension of subchondral bone involvement in upper limb (p 0.185) didn’t represent significant risk factors
