title: [Arthroscopic therapy of Baker's cyst with radiofrequency].
abstract: OBJECTIVE
  To explore the feasibility of arthroscopic therapy of Baker's cysts with radiofrequency.
  
  
  METHODS
  Since Feb. 2000 to Oct. 2002 a surgical arthroscopic treatment for popliteal cyst in a series of 21 patients. Men 14 and female 7, the age from 45 to 66 year. To do CT scan 11 and MR in 8. To insert a arthroscope to Baker's cyst, and inject salline in the visceral layer of capsule under the arthroscope, so that remove of the capsule easily. The radiofrequency to clear the capsule of cyst and hemostasia.
  
  
  RESULTS
  All of the cases studied, a connection between joint space and cyst was found in 13 cases. The popliteal cyst was found to be almost invariably associated with other knee disorders. Follow-up in all of the case. No nerve and blood vessel injure, no infection in this group. The function is well include 3 cases relapsed after re-operation by arthroscope debridement.
  
  
  CONCLUSIONS
  Surgical arthroscopic therapy of Baker's cysts is safety and reliable; To removal of capsule integrity and repair of all intraarticular lesions and sealing of the junction between Baker's cyst and the dorsal recessus of the knee joint for preventing recurrent are very important.
