[Total arthroscopic internal drainage technique for the treatment of popliteal cyst].

OBJECTIVE: To compare the clinical effects of total arthroscopic internal drainage and arthroscopic combined with posterior small incision in the treatment of popliteal cyst. METHODS: From January 2015 to January 2017, 60 patients with popliteal cyst were treated, including 29 males and 31 females, aged 30 to 65(47.8±2.5) years old, with a course of disease (8.5±4.2) months. Among them, 30 cases received total arthroscopic internal drainage for popliteal fossa cyst(total arthroscopic group), 30 cases received arthroscopic combined with posterior small incision for popliteal fossa cyst(arthroscopic combined with small incision group). The operation time, intraoperative bleeding volume, incision length, Rauschning and Lindgren grade 0 recovery rate and Lysholm score were compared between the two groups. RESULTS: Twenty-nine patients in total arthroscopy group were followed up, and 28 patients in arthroscopy combined with small incision group were followed up for 8 to 20(12.8±2.1) months. Operation time: total arthroscopic group(45.32±5.71) min, arthroscopic combined small incision group (44.56±3.85) min; Rauschning and Lindgren grade 0 recovery: 23 cases in total arthroscopic group, 22 cases in arthroscopic combined small incision group; postoperative Lysholm score: total arthroscopic group 84.5±11.2, arthroscopic combined small incision group 83.2±12.7; there was no significant difference between the two groups(P>0.05). Intraoperative bleeding volume: total arthroscopic group(5.32±1.25) ml, arthroscopic combined small incision group(20.75±8.18) ml; incision length: total arthroscopic group (1.51±0.34) cm, arthroscopic combined small incision group (7.34±0.75) cm; the difference between the two groups was significant(P<0.05). At the last follow-up, the knee joint was examined by magnetic resonance imaging, and no recurrence of cyst was found. CONCLUSIONS: Total arthroscopic internal drainage and arthroscopic combined with posterior small incision technique for popliteal fossa cyst with intra-articular lesions have the same clinical effect, but less trauma and faster recovery.

Clinical effects of acupuncture after surgical operation in patients with prolapse of the lumbar intervertebral disc.

OBJECTIVE: To investigate the clinical effects of acupuncture after surgical operation in patients with prolapse of the lumbar intervertebral disc (PLID). METHODS: Sixty-nine patients in this series, who had undergone the removal of nucleus pulposus and the intervertebral fusion as well, were randomly divided into a treatment group of 35 cases and a control group of 34 cases. The former was treated by acupuncture and conventional rehabilitation therapy, and the latter only by the rehabilitation therapy. The therapeutic effects were evaluated according to the scoring system stipulated by Japanese Orthopedics Association (JOA). RESULTS: In the treatment group, the average functional recovery rates in 3-month, 6-month and one-year periods were respectively 49.93%, 90.31% and 95.08%; while the rates were repesctively 26.24%, 63.42% and 71.36% in the control group, showing statistically significant difference between the two groups (P<0.05). CONCLUSIONS: Acupuncture can confirmatively promote the functional recovery for'patients with prolapse of the lumbar intervertebral disc after surgical removal of nucleus pulposus and with intervertebral fusion.
