Objective To compare the short and long term effect of knee osteoarthritis treatment with two therapeutic methods which are simple high cut of fibula and arthroscopic lavage debridement combined with fibular osteotomy.Methods Data of 45 consecutive patients with knee osteoarthritis were retrospectively observed and selected,and then they were divided into two groups according to the operation method.23 patients with simple high cut of fibula were selected as the control group,and 22 patients with arthroscopic lavage debridement combined with fibular osteotomy were selected as the observation group.Results The VAS and AKS scores of the control group at the time of 3m,6m,1 2m were (4.1 3 ±0.76)points,(1 07.04 ±21 .53)points;(2.70 ±0.64)points,(1 41 .1 7 ±1 2.57)points;(2.43 ±0.79)points,(1 48.26 ±5.81 )points;and the scores of the observation group were (3.45 ± 0.60)points,(1 26.64 ±1 4.24)points,(2.70 ±0.73)points,(1 46.45 ±7.26)points,(2.41 ±0.85)points and (1 48.26 ±5.81 )points.The differences between the two groups were statistically significant at the time of 3 months after surgery(t =3.32,-3.62,all P <0.05),the effect of observation group was better than the control group;but the other indices had no statistically significant differences (t =0.51 ,-1 .72,0.1 1 ,-0.20,all P >0.05 ). Conclusion The simple high cut of fibula with small trauma,less cost,less surgical difficulty,and long -term clini-cal curative effect is not less than the arthroscopic lavage and debridement combined with fibular osteotomy.There-fore,it should be carried out in the primary hospitals widely.

"The Expert Group on Tumor Ablation Therapy of Chinese Medical Doctor Association, The Tumor Ablation Committee of Chinese College of Interventionalists, The Society of Tumor Ablation Therapy of Chinese Anti-Cancer Association and The Ablation Expert Committee of the Chinese Society of Clinical Oncology" have organized multidisciplinary experts to formulate the consensus for thermal ablation of pulmonary subsolid nodules or ground-glass nodule (GGN). The expert consensus reviews current literatures and provides clinical practices for thermal ablation of GGN. The main contents include: (1) clinical evaluation of GGN, (2) procedures, indications, contraindications, outcomes evaluation and related complications of thermal ablation for GGN and (3) future development directions.
