  • ARTHROSCOPIC TREATMENT OF POPLITEAL CYST EXCISION IN COMBINATION WITH DEBRIDEMENT OF THE KNEE UNDER LOCAL ANESTHESIA

    ObjectiveTo evaluate the arthroscopic treatment effectiveness of popliteal cyst excision in combination with debridement of the knee under local anesthesia by comparing with continuous epidural anesthesia. MethodsBetween June 2002 and January 2013,145 patients with popliteal cyst underwent arthroscopic popliteal cyst excision in combination with debridement of the knee under local anesthesia (local anesthesia group).In addition,51 patients with popliteal cyst were treated with the same surgery under continuous epidural anesthesia between February 2000 and August 2005 served as control group.No significant difference was found in gender,age,side,disease duration,or cyst size between 2 groups (P>0.05).Then,anesthesia time,analgesia effect,anesthesia satisfaction,operation time,bleeding volume,and anesthesia complication were compared between 2 groups.The guidelines of Rauschning and Lindgren were used to assess the effectiveness,and recurrence rate was recorded. ResultsAll incisions healed primarily,no neurological or vascular injury was found.The patients were followed up 1 year and 1 month to 8 years (mean,3.7 years) in local anesthesia group,and 8 years to 13 years and 7 months (mean,10.8 years) in control group.Local anesthesia group had shorter anesthesia time,higher visual analogue scale (VAS) score,shorter operation time,and lower bleeding volume (P<0.05) than control group.Anesthesia satisfaction was reduced in local anesthesia group,but there was no significant difference (χ2=0.071,P=1.000).The anesthesia complication incidence of control group (15.7%,8/51) was significantly higher than that of local anesthesia group (0) (P=0.000).Recurrence was found in 12 patients of local anesthesia group (curative ratio 91.7%) and in 5 patients of control group (curative ratio 90.2%),showing no significant difference (χ2=0.111,P=0.774).According to the guidelines of Rauschning and Lindgren,there were 131 cases of grade 0,13 cases of grade I,and 1 case of grade Ⅱ in local anesthesia group,and 37 cases of grade 0,12 cases of grade I,and 2 cases of grade Ⅱ in control group; significant differences in grading were shown between at pre- and post-operation in 2 groups (Z=-10.683,P=0.000; Z=-6.385,P=0.000),and between 2 groups at post-operation (Z=-3.145,P=0.002). ConclusionCompared with under continuous epidural anesthesia,arthroscopic treatment of popliteal cyst excision under local anesthesia can obtain better results.Under local anesthesia,the condition of nerve and vessel can be timely and dynamically observed.Arthroscopic treatment of popliteal cyst excision in combination with debridement of the knee has the advantages of less trauma,lower recurrence rate,and satisfactory results.

  • ARTHROSCOPIC TREATMENT COMBINED WITH REPAIR OF JOINT CAPSULE USING TENDON FLAP OF MEDIAL HEAD OF GASTROCNEMIUS MUSCLE AFTER RESECTION OF POPLITEAL CYST

    ObjectiveTo investigate the methods and the effectiveness of arthroscopic treatment combined with repair of the cyst wall using the tendon flap of medial head of gastrocnemius muscle after resection of popliteal cyst. MethodsA retrospective analysis was made on the clinical data of 140 patients with popliteal cyst between August 2009 and June 2014, including 44 males and 96 females with a mean age of 54.68 years (range, 14-80 years). The median course of symptoms was 31 months (range, 20 days to 30 years). According to Rauschning and Lindgren criteria for popliteal cyst grade, 4 cases were rated as grade Ⅰ, 44 cases as grade Ⅱ, and 92 cases as grade Ⅲ. The preoperative Lysholm knee score was 68.99±8.23. Firstly, cyst was resected, then the hernia sac of joint capsule was repaired with the tendon flap of medial head of gastrocnemius muscle, and finally a knee arthroscopy was used for the diagnosis and treatment of intra-articular lesions. ResultsNo complication of nerve or blood vessel injury, infection, or necrosis occurred. The mean follow-up was 26 months (range, 6-64 months). During follow-up, 1 case (0.71%) had cyst recurrence. According to Rauschning and Lindgren criteria for popliteal cyst grade, 37 cases were rated as grade 0, 92 cases as grade Ⅰ, 10 cases as grade Ⅱ, and 1 case as grade Ⅲ at 6 months after operation, showing significant difference when compared with preoperative one (Z=-14.303, P=0.000); the Lysholm knee score (85.51±9.23) was significantly higher than preoperative score (t=-15.798, P=0.000). ConclusionArthroscopic treatment combined with repair of the cyst wall with the tendon flap of medial head of gastrocnemius muscle after resection of popliteal cyst is a better way to avoid recurrence.

  • Clinical prospective comparative study on short-term effectiveness of arthroscopic treatment of popliteal cyst between cyctectomy and internal drainage combined with cyctectomy

    ObjectiveTo compare the short-term effectiveness between arthroscopic cystectomy and internal drainage combined with cystectomy in popliteal cyst.MethodsBetween March 2014 and March 2017, 56 patients with symptomatic popliteal cyst were enrolled in the study, randomized block design was used to divided the patients into trial group (arthroscopic cystectomy combined with internal drainage group, n=28) and control group (arthroscopic internal drainage group, n=28). Excluding those who had incomplete follow-up and received surgery for other diseases postoperatively, 26 patients in the experimental group and 27 patients in the control group were finally enrolled in the study. There was no significant difference in gender, age, side, course of disease, maximum diameter and grade of popliteal cyst, and associated diseases between two groups (P>0.05). The operation time, duration of popliteal ecchymosis and the middle back of calf tenderness were observed postoperatively. The circumference of calf at 1 day, 1 week, and 2 weeks after operation were measured and the differences were calculated with the measurement before operation. Lower extremity venous thrombosis was observed by color doppler ultrasonography at 1 week after operation. The effectiveness was evaluated by Rauschning and Lindgren grading criteria. And MRI was used to observe whether the popliteal cyst disappeared or decreased and measured its maximum diameter at 1 year after operation.ResultsPatients in both groups were followed up 12-14 months, with an average of 12.5 months. The operation time, duration of popliteal ecchymosis, and the middle back of calf tenderness of the trial group were all longer than those in the control group (P<0.05), the differences of circumference of calf at 1 day, 1 week, and 2 weeks after operation of the trial group were greater than those in the control group (P<0.05). Color doppler ultrasonography of the lower extremity at 1 week after operation found that the intermuscular venous thrombosis occurred in 2 cases of the trial group, while no lower extremity thrombosis was found in the control group; and the difference between two groups was not significant (P=0.236). According to the Rauschning and Lindgren grading criteria, there were 16 cases of grade 0, 6 cases of grade 1, and 4 cases of grade 2 in the trial group, and 17 cases of grade 0, 4 cases of grade 1, and 6 cases of grade 2 in the control group at 1 year after operation. There was no significant difference between 2 groups (Z=–1.872, P=0.078). Nine cases (34.62%) of the trial group and 13 cases (48.15%) of the control group still have residual cysts by MRI, the maximum diameter of which was less than 2 cm. The cysts disappeared in the remaining patients in both groups, and there was no recurrence during the follow-up. There was no significant difference in cyst residual rate between 2 groups (χ2=2.293, P=0.852).ConclusionCompared with arthroscopic internal drainage, the short-term effectiveness of the arthroscopic internal drainage combined with cystectomy had no significant improvement, and the operation time was prolonged, the postoperative complications were obviously increased.
