OBJECTIVETo observe the curative effect of musculoskeletal ultrasound-guided needle-knife on the degenerative meniscus disease, and to provide a new method in the treatment of degenerative meniscus disease.

METHODSSeventy-seven patients with degenerative meniscus disease treated in the Third Affiliated Hospital of Beijing University of Chinese Medicine from January 2015 to September 2015 were selected, including 30 males and 47 females, aged from 44 to 66 years old, with an average of 57.5 years old. VAS scores, Lysholm scores and distance of meniscal protrusion were analyzed and compared before treatment, 2 weeks and 1 month after treatment. The curative effect was summarized at last.

RESULTSThe mean Lysholm scores were 51.63±15.26(before treatment), 77.13±11.82(2 weeks after treatment) and 87.56±8.65(1 month after treatment). The mean VAS scores were 7.080±1.574 (before treatment), 2.630±0.310(2 weeks after treatment) and 0.850±0.177(1 month after treatment). The mean of the distance of meniscal protrusion scores were 0.400±0.156 (before treatment), 0.298±0.140 (2 weeks after treatment) and 0.240±0.110 (1 month after treatment). VAS scores and Lysholm scores were improved significantly compared with preoperative results. The distance of meniscal protrusion showed an obvious improvement after treatment.

CONCLUSIONSThe treatment of musculoskeletal ultrasound-guided needle-knife has advantages of high accuracy position and excellent effectiveness for degenerative meniscus disease. The treatment provides safety operation and significantly improves quality of life in patients without any complications.
