“…A total of five patients in this group (0.7%) had a ruptured Baker’s cyst on USS. The prevalence of Baker’s cysts is higher in this study compared to other studies, with the prevalence of Baker’s cysts reported between 7% and 30% 14–23 (see Table 3). Patients in these studies were predominantly Rheumatology patients or patients with knee pain assessing the diagnosis and management of knee OA.…”

“…Another study researched into the prevalence of Baker’s cysts in patients with known OA and reported 87.1% (1365) patients had no Baker’s cyst. 19 However, this study did not compare the clinical examination to the ultrasound findings. In addition, patients were only included because they had OA rather than a clinical suspicion of a Baker’s cyst; therefore, the number of normal examinations is expected to be higher than in this study.…”

Ultrasound for suspected Baker’s cyst: A test of limited clinical value?

2023

Introduction: Patients with posterior knee swellings are commonly encountered in clinical practice with the vast majority referred for an ultrasound scan to assess for a clinically suspected Baker’s cyst. Aims: Our aim was to determine the incidence of different pathologies in patients investigated for a posterior knee swelling of a clinically suspected Baker’s cyst using ultrasound. We also wanted to investigate the incidence of significant pathologies in the popliteal fossa to assess whether the ultrasound scan findings influenced patient management. Methodology: Retrospective analysis was performed on all patients who underwent an ultrasound scan for a suspected Baker’s cyst or posterior knee swelling at our institution, between January 2017 and December 2018. Patient demographics, ultrasound findings, further imaging investigations and histopathology were recorded. Patient records were followed up for a minimum period of 3 years after ultrasound. Results: A total of 680 patients had a posterior knee ultrasound scan. Of that, 51% (347/680) had a Baker’s cyst and 40% (273/680) had a normal ultrasound scan. Sixty (9%) patients had other abnormalities identified within the popliteal fossa. Four patients had significant findings on ultrasound that required a change of management. No malignancies identified. Conclusion: This study confirms the high incidence of Baker’s cysts in patients presenting with a posterior knee swelling. In the absence of red flag symptoms, ultrasound of the posterior knee for a clinically suspected Baker’s cyst is of limited clinical value.

Ultrasound for suspected Baker’s cyst: A test of limited clinical value?

“…Literature data are conflicting. Some authors found that the presence of the bursa may play a role in exacerbating pain due to KOA [10,12,13,[17][18][19], whereas others have not observed any relationship with pain and other symptoms [8,9,11,20]. These discrepancies can be explained by several factors: patients selection (community dwelling or subjects seen in rheumatologic services), demographic differences, different degree KOA, methods of investigation, and others.…”

“…It may be detected incidentally in the general population but is more fre-quently found in patients suffering from knee osteoarthritis (KOA) [1][2][3][4][5][6]. In these patients the prevalence ranges from 20% to 40%, and increases with age, severity of OA, and duration of disease [7][8][9][10][11][12][13]. This figure is not surprising given that in almost 30-50% of cases a connection is present between the knee articular space and the gastrocnemio-semimembranosus bursa.…”

“…So, it is debated whether and to what extent each condition contributes to the patient's discomfort. Besides authors who claim that the presence of the enlarged bursa may increase the symptoms of KOA [10,12,13,[17][18][19], others have not observed any relationship with pain and other discomfort [8,9,11,20]. In order to disentangle this complex issue, the aims of the present study were to evaluate the burden of symptoms in patients with different Kellgren-Lawrence (K-L) degree of KOA, comparing those with and without BC, and to assess the outcomes after conservative treatments in both groups.…”

Baker’s Cyst with Knee Osteoarthritis: Clinical and Therapeutic Implications

et al. 2021

Objective: Several symptoms are common to knee osteoarthritis and Baker’s cyst. To what extent each condition contributes to the patient’s discomfort is still a matter of debate. The aim of the present study was twofold: first, to compare the burden of symptoms in patients with isolated knee osteoarthritis and patients with knee osteoarthritis associated with Baker’s cyst; second, to assess the outcomes after conservative treatments. Subject and Methods: Patients suffering from monolateral idiopathic knee osteoarthritis were enrolled. Demographic, anthropometric and clinical data (KOOS scale) were collected. Ultrasound evaluation was performed according to standard protocols. On the basis of the clinical presentation different therapeutic options were used (fluid withdrawal, hyaluronic acid and/or steroids injections). Results: One-hundred and thirty patients were included in the study (97 with isolated knee osteoarthritis, 33 with knee osteoarthritis and Baker’s cyst). In basal conditions, lower scores in KOOS sub-scales were observed in patients with knee osteoarthritis associated with Baker’s cyst and in patients with effusion compared with patients without effusion. At 3 months after therapy significant higher scores were observed in both groups. At 6 months the scores were unchanged in the patients without Baker’s cyst, but worsened in those with Baker’s cyst. Conclusions: The study shows that Baker’s cysts associated with knee osteoarthritis contribute to the burden of symptoms. The conservative treatment of both conditions allows significant improvements, but in the medium term (6 months) the efficacy of the therapy declines in patients with knee osteoarthritis associated with Baker’s cyst.
