title: [Soft tissue changes observed through musculoskeletal ultrasound in the treatment of knee osteoarthritis with needle-knife].
abstract: OBJECTIVE
  To study soft tissue changes observed through musculoskeletal ultrasound (MSUS) in the treatment of knee osteoarthritis with needle-knife, so as to provide MSUS basis for needle-knife in the treatment of knee osteoarthritis.
  
  
  METHODS
  Forty patients with knee osteoarthritis treated in the Third Affiliated Hospital of Beijing University of Chinese Medicine from December 2011 to December 2012 were selected according to inclusion and exclusion criteria. All the patients were treated with needle-knife release method. The VAS scores and knee joint circumference were recorded before treatment and 2 weeks after treatment. The changes of knee joint hydrops articuli and joint synovial thickness were measured through MSUS.
  
  
  RESULTS
  The knee pain index was 6.850 +/- 1.417 before treatment and 2.790 +/- 1.299 after treatment;the index after treatment was lower than that of before treatment. The knee joint circumference was 407.320 +/- 45.151 mm before treatment and 391.240 +/- 41.129 mm after treatment; the knee joint circumference decreased after treatment. The amount of hydrops articuli observed by musculoskeletal ultrasound showed that 47 knees were cured, 19 knees improved and 2 knees failed. The synovial membrane thickness: 43 knees cured, 17 knees improved and 8 knees failed.
  
  
  CONCLUSIONS
  The hydrops articuli and synovial thickness of knee joint of patients with knee osteoarthritis observed under the MSUS is consistent with the main symptoms and signs, which suggests that MSUS observation on soft tissue changes before and after needle knife in the treatment of knee osteoarthritis with high reliability.
