Analysis of the efficacy of triple-channel minimally invasive knee arthroscopy in treating popliteal cysts in children

BackgroundThis study aimed to investigate a technique for treating pediatric popliteal cysts with a triple-channel knee arthroscopic approach, hypothesizing that this technique exhibits favorable clinical outcomes with reduced recurrence rates.MethodsA retrospective analysis was conducted on the clinical data of 14 patients with symptomatic pediatric popliteal cysts admitted to the joint surgery center using an arthroscopic minimally invasive technique from December 2017 to December 2020. Arthroscopy was employed for adequate enlargement of the posterior medial flap opening between the cyst and the joint cavity and to completely resect the cyst wall. The popliteal cyst recurrence was assessed through Magnetic Resonance Imaging(MRI) at 3 and 12 months post-surgery, and the Rauschning and Lindgren scores were recorded to evaluate the clinical prognosis.ResultsA total of 14 children completed the follow-up, including 8 boys and 6 girls, with a mean age of 9.9 ± 1.1 years (5–12 years); 5 cases in the left knee and 9 cases in the right knee; the mean operative time was 19.2 ± 2.7 min (10–25 min); and the mean follow-up time was 15.1 ± 2.4 months (12–24 months). There was no intraoperative vascular or nerve injury and no incisional exudate infection. Postoperatively, posterior knee symptoms disappeared in the children, Rauschning and Lindgren scores significantly improved, and no recurrence signs were observed on MRI.ConclusionsThis study determined that the arthroscopic three-channel minimally invasive technique is effective and safe for treating popliteal cysts in children, making it worthy of clinical promotion.

Comparison of arthroscopic internal drainage and open excision for the treatment of popliteal cysts

BackgroundThe purpose of this study was to introduce the arthroscopic internal drainage with anterior-anteromedial approach for the treatment of popliteal cysts in children. To compare its clinical efficacy with open surgery.MethodsThis was a retrospective case–control study of 102 patients diagnosed with popliteal cysts from January 2018 to February 2020 who received surgery. The study included 27 cases with minimally invasive group (MI group) and 75 cases with open surgery group (OS group). The MI group included 21 males and 6 females, age 6.71 ± 2.16 years who received arthroscopic internal drainage of the cysts to adequately widen the valve opening between the cyst and the articular cavity, excised the fibrous diaphragm without complete excision of the cyst wall. The OS group included 57 males and 18 females, age 6.21 ± 1.67 years who received open excision. The clinical parameters regarding the preoperative characteristics and surgical results were compared. Ultrasound or MRI was used to identify the recurrence of the popliteal cysts. Rauschning-Lindgren grade was recorded to evaluate the clinical outcome.ResultsAll patients were followed up for at least 24 months. There were no significant differences between the two groups in age, gender, left and right sides, disease time, cyst size, length of hospitalization, preoperative Rauschning-Lindgren grade (p > 0.05). At the last follow-up, the preoperative and postoperative Rauschning-Lindgren grade was improved in both groups. Compared with the OS group, operation time was significantly shortened in the MI group (28.89 ± 4.51 min vs 52.96 ± 29.72 min, p < 0.05). The MI group was superior to the OS group in terms of blood loss and plaster fixation, with statistical significance (p < 0.05). There was obvious difference in recurrence rate between the two groups (0% vs 17.33%, p = 0.018). No postoperative complications occurred during the follow-up period.ConclusionsCompared with open excision, the treatment of popliteal cyst in children by arthroscopic internal drainage to expand the articular cavity and eliminate the “one-way valve” mechanism between the cyst and the articular cavity exhibits better clinical outcomes and significantly reduces the recurrence rate, which is worthy of further clinical promotion.

Popliteal cysts in children: another look.

This retrospective review of 46 popliteal cysts seen in 44 patients at a pediatric orthopedic referral center clarifies the presenting symptomatology, associated conditions, and likely duration of a popliteal cyst, and the need for intervention. The patients were followed up for more than 1 year. Thirty-six of the 46 cysts with duration data showed no resolution of the popliteal cyst during the period of observation (average, 32.1 months). The 10 cysts that showed clinical resolution were present for an average of 16.9 months. The benign course of action for virtually all patients obviated the need for intervention and supports the adequacy of only clinical examination, with no need for recurrent sonography.

Popliteal cysts in children.

Abstract Twenty-six popliteal cysts arising in persons under 20 years of age have been excised. In no case was the cyst found to communicate with the knee-joint. Preoperative radiographs in 10 cases confirmed the absence of such a communication. Popliteal cysts in children are congenital bursae and not synovial herniations from the joint. The apparent disappearance of such cysts on flexing the knee is due to the displacement of the bursa to the medial aspect of the knee and not to the displacement of the fluid contents into the joint.

Long-term follow-up of conservatively treated popliteal cysts in children.

This study was undertaken to determine the long-term outcome of conservatively treated popliteal cysts in children. It was based on a review of 20 cysts, none of which were initially treated surgically. The records of children with popliteal cysts between 1986 and 1992 were studied, and a group of patients without other diseases or other physical abnormality in the knee region was selected. Twenty-one patients were included and were subjected to a clinical and ultrasound investigation. Three were lost to follow-up, leaving 18 patients with 20 cysts available for analysis. In the follow-up period, which ranged from 5 to 10 years, 14 cysts were treated conservatively with a mean follow-up of 7 years, whereas 6 cysts were operated on after a mean period of 2 years. Of the conservatively treated cysts, eight had disappeared and six had shrunk. Although spontaneous remission is not to be expected in all cases, asymptomatic popliteal cysts in children can be treated conservatively with good results.

Popliteal cysts in children: prevalence, appearance and associated findings at MR imaging

The purpose of this study was to determine the prevalence of Baker's cysts on MR images in a paediatric orthopaedic population, to investigate the association of Baker's cyst with joint fluid and joint disorders in children, and to compare the MR appearance of Baker's cysts in children with that previously reported in adults. Reports from 393 MR studies of the knee performed in children aged from 1 to 17 years were retrospectively reviewed for the presence of a Baker's cyst, joint effusion, meniscal tear, anterior cruciate ligament tear, or any other joint disorder. A Baker's cyst was identified in 6.3 % (25/393) of patients. The MR images and clinical charts of patients with a Baker's cyst were reviewed. None of the 25 patients with a Baker's cyst had an associated anterior cruciate ligament tear or meniscal tear. Two patients had osteochondritis dissecans and two others had synovial disease (infection and juvenile rheumatoid arthritis). Joint fluid was demonstrated in 16 % (4/25) of patients with a Baker's cyst. There was no statistically significant association between presence of a Baker's cyst and presence of joint fluid. Baker's cyst is less prevalent in a paediatric orthopaedic population than in an adult population. In children, it seems that Baker's cyst is seldom associated with joint fluid, meniscal tear, or anterior cruciate ligament tear. On MR images, a communication between the Baker's cyst and the joint was not demonstrated in any of the patients. In addition, the presence of debris and cyst leakage was not observed.

Prevalence of popliteal cysts in children. A sonographic study and review of the literature.

Popliteal cysts in children differ from those in adults. They are considered to be less frequent and usually appear in the absence of intra-articular lesions. However, their prevalence in asymptomatic children is unknown. We present a prospective epidemiological study of 168 asymptomatic children under 15 years of age hospitalised for various pathologies. Children with knee problems and rheumatic diseases were excluded from the study. The children were examined ultrasonographically with a 7.5 MHz linear scanner. A popliteal cyst could be identified in 4 patients. The prevalence of asymptomatic popliteal cysts was thus 2.4%. For 2 of these patients, we obtained magnetic resonance image of the knee which showed no concommitant intra-articular pathology.

The natural history of popliteal cysts in children: an ultrasound study.

The natural history of juvenile popliteal cysts is poorly defined. No previous study has used imaging to prove these cysts spontaneously resolve. Over 4 years, 14 children presented with popliteal swellings consistent with a popliteal cyst. A single ultrasound scan confirmed the diagnosis and measured the cyst dimension. No treatment was instituted. At a mean follow up of 28.6 months, repeat examination and ultrasound confirmed resolution of the popliteal cyst in seven cases. In six cases ultrasound confirmed the popliteal cysts remained at a mean follow up of 16.5 months. No cyst increased in size. True juvenile popliteal cysts can resolve spontaneously. This is accurately demonstrated with ultrasound imaging.

POPLITEAL CYSTS IN CHILDREN

The natural history of 120 popliteal cysts in children has been reviewed. Of seventy untreated cysts fifty-one disappeared spontaneously during a mean period of one year and eight months. Of fifty cysts submitted to operation, twenty-one recurred in a mean period of seven months. Three children with recurrences had more than one further operation. Most popliteal cysts in children disappear spontaneously, and operation without very good reason is unjustified.

POPLITEAL CYSTS IN ADULTS AND CHILDREN. A REVIEW OF 90 CASES.

Introduction This review presents an analysis of 90 consecutive surgically treated popliteal cysts in 84 (private and service) patients at The Hospital for Special Surgery from 1938 to 1960. In particular it contrasts the clinical differences in the adult and children's popliteal cyst. A strikingly high incidence of popliteal cysts, occurring at the midportion of the first decade in children, is noted in this series. The curious absence of associated joint disease and a salient history in children, as contrasted with the presence of such findings in adults, suggests a dissimilar etiology for the two age groups. The precise similarity, however, of the anatomical origin of the cyst in each group suggests common factors. The earliest mention of popliteal cysts in the literature was by Adams in 1840. He described an enlargement of the bursa beneath the medial head of the gastrocnemius which communicated with the knee joint, and which
