“…Also, another study showed that there is a significant correlation between the size of the BC and the stage of OA according to the Kellgren-Lawrence classification. This study found that BC is more common in patients with advanced stages of OA and that cyst size is directly proportional to the severity of OA [25].…”

“…Researching the international databases regarding the change in size of the BC depending on various factors, we conclude that there are not much data regarding this aspect. It seems that there is evidence that an increase in chondral lesion severity increases the amount of effusion and cyst volume, the degree of chondral lesion was moderately and positively correlated with cyst volume in the total population, and the degree of the chondral lesion was moderately and positively correlated with the degree of effusion [25]. At the same time, cartilage degeneration, medial plicae, and an increase in intra-articular effusion may increase the BC volume [34].…”

The Baker cyst (BC), also known as the popliteal cyst or parameniscal cyst, is a fluid-filled sac that normally develops in the back of the knee, between the semimembranosus and medial head of the gastrocnemius. We aimed to evaluate the effectiveness of physiotherapy (10 days of treatment) that associates intermittent vacuum therapy (IVT) on the lower limbs in the treatment of the BC, respectively, in its size reduction. Sixty-five patients with knee osteoarthritis using Kellgren–Lawrence criteria and the presence of BC (ultrasonography evaluation), were divided into the Control and Vacuum groups. We collected the following features: sex, age, level of education, occupation, environment, body mass index, Knee Injury and Osteoarthritis Outcome Score, Western Ontario, and McMaster Universities Osteoarthritis Index, the Functional Independence Measurement, the Fall Risk Score, and the Visual Analog Scale were recorded at baseline and after 10 days. Both groups are similar in terms of demographic features. Regarding the clinical functional parameters, the results elicit a statistically significant change in all parameters between admission and discharge, including the echo volume at BC. Physical medicine and rehabilitation increase the autonomy of patients with BC. Clinical-functional improvement begins in the first 10 days of complex rehabilitation treatment; it is statistically significant and is not different between the two groups, which brings an additional argument for the effectiveness of conservative therapy in the treatment of BC. Although IVT has not demonstrated its superiority over classical balneo-physical therapy, additional research, and long-term monitoring are needed to provide additional arguments regarding this aspect.

“…In clinical conditions, such as inflammatory or degenerative arthropathy, which can cause increase of intra-articular pressure due to increase of joint effusion, the effusion may enter into the cyst. Furthermore, development of Baker’s cyst was associated with ACL tear and meniscal tear [ 15 16 17 ]. Therefore, it was thought that there may be factors contributing to the cyst rupture, just as there were many factors affecting the cyst development.…”

Objectives: To identify the factors associated with Baker’s cyst rupture on MRI. Material and methods: From January 2021 to December 2022, a total of 441 knee MRI examinations in 441 patients (mean age: 47.7 ± 13.8 years) with Baker’s cyst were included in this study. Patients were classified into two groups: those with ruptured vs. unruptured Baker’s cysts. On knee radiograph, osteoarthritis grade was assessed based on Kellgren-Lawrence grade. On MRI, combined structure injuries, alignment type between semimembranosus tendon and medial head of gastrocnemius tendon, amount of joint effusion, presence of septation, maximal diameters of cyst, and cyst volume were evaluated. Receiver operating characteristic (ROC) analysis was performed to assess the predictive performances of imaging factors for cyst rupture. Results: There were 146 patients with Baker’s cyst rupture and 295 patients without rupture. Patients with cyst rupture showed significantly longer maximal transverse diameter (25.8 ± 6.8 mm vs. 21.6 ± 5.8 mm, p = 0.035) and larger volume (13.3 ± 6.2 cm 3 vs. 9.9 ± 5.1 cm 3 , p = 0.012) than those without rupture. On ROC analysis, maximal transverse diameter of cyst ≥ 22.2 mm (sensitivity = 64.4%, specificity = 54.9%) and cyst volume ≥ 10.9 cm 3 (sensitivity = 71.2%, specificity = 58.3%) were the cutoff values for predicting rupture of cyst, respectively. The cyst volume showed significantly higher area under the curve (AUC) than maximal transverse diameter (0.726 vs. 0.642, p = 0.002). Conclusion: Longer transverse diameter and larger volume of Baker’s cyst could be predictive imaging parameters for cyst rupture.

Background: Popliteal (Baker) cysts are enlarged gastrocnemius-semimembranosus bursae leading to swelling in the popliteal fossa. Surgical decompression and capsulectomy is the definitive treatment for symptomatic cysts with arthroscopic or open decompression. Arthroscopic decompression is minimally invasive, entails lower risks, and allows for earlier and more aggressive rehabilitation compared with open excision. Indications: Indications for popliteal cyst decompression include pain and mechanical discomfort refractory to conservative treatment. Further indications are neurovascular compromise secondary to bursal enlargement, including thrombophlebitis, compartment syndrome, limb ischemia, and nerve entrapment. Additional considerations include concurrent pathology requiring surgical intervention. Technique Description: Following standard diagnostic arthroscopy, a Gillquist maneuver is performed to visualize the posteromedial compartment and transverse synovial fold. The operative limb is placed in a modified figure-of-four position. A posteromedial portal is established under spinal needle localization and utilized to debride the anterior capsular wall and cyst contents with an arthroscopic shaver. Attention is paid to the removal of the posterior transverse synovial infold to reduce risk of recurrence. Results: The literature reports favorable outcomes in arthroscopic decompression of popliteal cysts. In comparison of arthroscopic and open decompression, You et al. reported reduced mean operative time and reduced recurrence rate following arthroscopic management. In a retrospective study, Rupp et al. reported increased rates of cyst recurrence with concurrent meniscal and/or chondral injuries highlighting the importance of addressing concurrent intra-articular pathologies during decompression. Discussion/Conclusion: Arthroscopic decompression of symptomatic popliteal cysts can be performed safely and effectively. Arthroscopic approach allows for treatment of concurrent pathologies that predispose to increased rates of cyst recurrence. Nonetheless, rates of recurrence vary widely and therefore further study in treatment technique is necessary.
