Abstract
Objective:To compare technique and clinical effect of arthroscopic and conventional sectional therapy for the treatment of ischial tuberosity cyst.Methods:From May 2014 and September 2016,49 patients with symptomatic ischialtuberosity cyst were randomized divided into arthroscopic group and conventional section group by envelope method.There were 24 patients in arthroscopic group,including 16 males and 8 females aged from 42 to 81years old with an average age of (64.1 ±9.3) years old;the courses of disease ranged from 2 to 36 months with an average of (17.0±9.1) months;treated with removing cyst wall under arthroscopic and build artificial lacuna around cyst.There were 25 patients in conventional section group,including 11 males and 14 females aged from 47 to 79 years old with an average of (61.2±10.6) years old;the courses of disease ranged from 4 to 36 months with an average of (17.5±8.5) months;treated with cutting off lump with transverse incision.Operative time,blood loss,fluid volume,hospital stays and postoperative complication were observed and compared,VAS score were applied to evaluate pain degree.Results:Forty-nine patients were followed up from 6 to 18 months with an average of (11.3±3.3) months.In conventional group,2 patients occurred incision infection,1 case reoccurred.All patients in arthroscopic group were healed at stage Ⅰ.Operative time,blood loss,fluid volume,and hospital stays in arthroscopic group were (54.7±7.7) min,(20.8±3.5) ml,(20.3±5.6) ml,(2.8±0.6) d respectively and better than that of conventional group (71.8± 8.8) min,(67.3±12.0) ml,(103.6±20.3) ml,(7.8±2.9) d.Postoperative VAS score in arthroscopic group on the first day,seventh days and first month were 2.6±0.7,0.5±0.6,0.3±0.5,and significantly lower than that of conventional group 6.0±0.7,3.0± 1.0,1.1±1.0 respectively(P＜0.05).There were no statistical difference in postoperative complications between two groups (P＞ 0.05).Conclusion:Compared with conventional group,arthroscopic for ischial tuberosity cyst has advantages of minimal invasive,less blood loss during perioperative period,less pain degree after surgery,safety and rapid recovery.But arthroscopic skills are needed for surgeons.It should be recommended in clinical practice.关键词
