OBJECTIVE: To investigate efficacy between arthroscopic popliteal cyst drainage and arthroscopic popliteal cyst resection. METHODS: From January 2013 to June 2021, 54 patients with popliteal cyst (Rausching-Lindgren gradeⅠto Ⅲ) were treated with arthroscopic surgery. There were 24 males and 30 females. The age ranged from 44 to 72 years old, with a mean of (62.67±6.08) years old. The course of the disease ranged from 1 to 72 months, with a mean of(15±14) months. Twenty-four patients (group A) were underwent arthroscopic internal drainage of popliteal cyst. Thirty patients (group B) were underwent arthroscopic resection of popliteal cyst. Preoperative main symptoms included knee pain, swelling, walking pain, popliteal swelling, popliteal mass and so on. After 1, 3, 6 months and 1, 2 years of surgery, routine outpatient follow-up was conducted to observe and compare the surgical time, bleeding volume, preoperative and postoperative visual analog scale (VAS), knee Lysholm score, and complications between two groups. RESULTS: All incisions healed at one stage after operation. All 54 patients were followed up, and the duration ranged from 6 months to 2 years, with an average of (13.89±4.29) months. There was no intraoperative vascular or nerve injury. Operation time and intraoperative blood loss of the two groups:group A of (62.08±9.55) min and (8.00±1.69) ml, group B of (69.50±6.99) min and (8.70±2.00) ml. Popliteal pain, swelling, limitation of flexion and extension were significantly relieved after operation. VAS before and one month after operation between two groups:group A of 5.38±1.21 and 2.63±0.71, group B of 5.60±1.26 and 2.80±0.81. Lysholm scores of knee joint before and 6 months after operation:group A of 62.59±4.99 and 89.74±2.90, group B of 63.87±3.23 and 89.02±2.35. Knee joint function improved significantly in both groups. In group A, 4 cases had popliteal cyst at 3 months after operation, and 2 cases had small isolated cyst at 1 year after operation. There was no recurrence of cyst in group B. CONCLUSION The results between two arthroscopic treatments of popliteal cyst are satisfactory, and there is no significant difference in the amount of blood loss, safety, postoperative pain VAS score and knee function recovery. It is suggested that arthroscopic resection of the cyst wall should be performed when the technique is mature, especially for large cysts and septal cysts.

Baker's cysts are rare cause of peripheral nerve entrapment and only a few cases of tibial nerve entrapment resulting from the popliteal cyst in the calf muscle have been reported in the literature. We present a case of rheumatoid arthritis complicated by a Baker's cyst with a tibial nerve entrapment. It is important to diagnose a Baker's cyst early and to differentiate it from thrombophlebitis, a popliteal aneurysm, tumor or muscle tear to effect optimal therapy and to obviate a potential neuropathy. Prompt recognition of these cases may save the patients unnecessary procedures and delay in treatment.

OBJECTIVETo study the clinical effect of arthroscopic excision of popliteal cysts through a combined anterior and posterior approach.

METHODSFrom January 2010 to December 2012,20 patients with popliteal cysts were treated with arthroscopic excision. There were 14 males and 6 females, with an average age of 49.5 years old, ranging from 45 to 65 years old. The lump has been found for 4 to 18 months,with a mean time of 12 months. Their mean sagittal diameter was 4.5 cm (ranged from 3 to 7 cm). There were 12 popliteal cysts in the left and 8 popliteal cysts in the right. The main clinical manifestation included lump at popliteal fossa, swelling and pain at knee joint and some extent of dysfunction. All diagnoses were determined according to MRI, which clearly showed the communication of cyst and articular cavity. The cyst was removed under arthroscopy, through the posterior approach and then the intra-articular lesion was treated via the anterior approach. According to Rauschning and Lindgren classification, 2 patients were grade I, 6 patients were grade II, and 12 patients were grade III. The guidelines of Rauschning and Lindgren were used to evaluate the clinical effects.

RESULTSNo complications such as the injury of blood vessel and nerve, or incision infection occurred in all patients. All the patients were followed up, and the duration ranged from 8 to 24 months, with a mean time of 16 months. According to the criteria of Rauschning and Lindgren, there were 14 cases of grade 0, and 6 cases of grade I after operation, which was improved obviously compared with that pre-operation. No cyst reoccurred and the knee joint pain was relieved.

CONCLUSIONTreatment of popliteal cysts with arthroscopic excision through a combined anterior and posterior approach is effective to remove the cyst sac and treat intra-articular diseases simultaneously, resulting in the decrease recurrence rate of cyst.

OBJECTIVETo explore the treatment methods and the effects of popliteal cyst with arthroscopy.

METHODSFrom January 2009 to January 2010,20 patients with popliteal cyst were treated with internal drainage under arthroscope, meanwhile, their joint disease were treated. There were 9 males and 11 females with an average age of (55.7 +/- 7.7) years (ranged, 46 to 70). The lump was found for 1-22 months with an average of (6.2 +/- 2.4) months and accompanying with knee pain of different degrees. All diagnosis depended on B ultrasound or MRI, which clearly showed communication of cyst and articular cavity. According to the grade of Rauschning and Lindgren,grade II was in 8 cases and grade III was in 12 cases. The clinical effects were evaluated by the grade of Rauschning and Lindgren.

RESULTSAll the patients were followed up from 6 to 18 months with an average of 12 months. No injuries of blood vessels and nerve or incision infection were found. The grade of Rauschning and Lindgren improved obviously in all patients, grade 0 was in 13 cases, grade I in 6 cases, grade II in 1 case at the 6 months after operation.

CONCLUSIONThe method not only can cure the popliteal cyst, but also can solve the disease of joint, which is avoiding re-operation and decreasing some shortages of traditional operation, can obtain good function recovery and satisfactory medium-term effects.

OBJECTIVETo explore the feasibility of arthroscopic therapy of Baker's cysts with radiofrequency.

METHODSSince Feb. 2000 to Oct. 2002 a surgical arthroscopic treatment for popliteal cyst in a series of 21 patients. Men 14 and female 7, the age from 45 to 66 year. To do CT scan 11 and MR in 8. To insert a arthroscope to Baker's cyst, and inject salline in the visceral layer of capsule under the arthroscope, so that remove of the capsule easily. The radiofrequency to clear the capsule of cyst and hemostasia.

RESULTSAll of the cases studied, a connection between joint space and cyst was found in 13 cases. The popliteal cyst was found to be almost invariably associated with other knee disorders. Follow-up in all of the case. No nerve and blood vessel injure, no infection in this group. The function is well include 3 cases relapsed after re-operation by arthroscope debridement.

CONCLUSIONSSurgical arthroscopic therapy of Baker's cysts is safety and reliable; To removal of capsule integrity and repair of all intraarticular lesions and sealing of the junction between Baker's cyst and the dorsal recessus of the knee joint for preventing recurrent are very important.

OBJECTIVETo retrospective study the results of arthroscopic resection of articular capsule valvular treated popliteal cysts and examined the incidence of complication.

METHODSFrom July 2007 to July 2010, 45 patients with symptomatic popliteal cysts such as knee pain and limitation of motion were treated with arthroscopic technique to resect the connecting valvular mechanism at posteromedial compartment of articular capsule. Through the posteromedial viewing portal and cyst resection working portal, resected the valvular mechanism by shaver and plasma cutter, associated intra-articular pathology was treated simultaneously. The functional outcome was evaluated by employed Rauschning and Lindgren score before the surgery and the last follow-up. By using of Wilcoxon rank sum test to statistics analyze the clinic outcome.

RESULTIn all cases, 40 patients were found the associated intra-articular pathology, the incidence was 88.9%.The intra-articular pathology was medial meniscus tear (27 cases, 60.0%), lateral meniscus tear (20 cases, 44.4%), cartilage lesion (28 cases, 62.2%), which composed with patellofemoral joint (12 cases, 26.7%),medial condyles of femur (10 cases, 22.2%),lateral condyles of femur (6 cases, 13.3%). The anterior cruciate ligment injury was found in 2 cases, the incidence was 4.4%. All the patients achieved symptoms relief postoperative, such as posterior knee discomfort and swelling after activities.The Rauschning and Lindgren score was improved 1-2 grade in average (Z = -6.092, P = 0.00). The recurrence rate was 2.2%. All the incision healed good. No major complications were encountered such as saphenous nerve, great saphenous vein, blood vessel in popliteal injury.

CONCLUSIONSArthroscopic resection of articular capsule valvular treatment of popliteal cyst and treatment of associated intra-articular pathology are effective and safe. This surgery technique has more minimally trauma and lower recurrence rate.The clinic results in short term are excellent.
