Abstract

Aim: Previous publications have described various therapeutic modalities for symptomatic cysts, including non-steroidal anti-inflammatory drugs, cystostomy, physical therapy, and exercises. The objective of thise study was to elucidate the effectiveness of shrinking the cyst without steroidal injection and to compare aspiration with classic physiotherapy and exercises.
Material and Method: This randomized, controlled trial involved 40 patients with Baker’s cyst. The participants were randomized into two groups, (I) an aspiration group (n=20) and (II) a control group (n=20). In the aspiration group, Baker’s cyst content was aspirated percutaneously under USG guidance, while no aspiration was performed in the control group. Pain was evaluated with a visual analog scale, while the Lysholm knee scoring scale and Cincinnati knee rating system were employed to determine functional status. Quality of life and disability were evaluated using the Nottingham Health Profile and the Western Ontario and McMaster Universities Arthritis Index .
Results: Differences were observed in USG measurements (width, length, and area) and clinical parameters before and after treatment in both groups. However, although these differences were greater in the aspiration group, they were not statistically significant.
Conclusion: Our results indicate that cyst aspiration performed with USG provides no additional effect to those of physical exercises and cold application. Exercise therapy and cold application should be considered before proceeding with an invasive procedure.
