Background Knee pain and limitation of joint movement are common compliant in pain clinic due to knee osteoarthritis and often associated with Baker's cyst. These are usually asymptomatic during the initial phase and might be missed during clinical examination and later may present in complicated form. Musculoskeletal ultrasonography might be helpful in detecting asymptomatic Baker's cyst during the early course of the disease. Objective To observe the incidence of Baker's cyst in patient with primary osteoarthritis of knee with the help of routine musculoskeletal ultrasonography of knee during clinical evaluation of patient. Method A total of 114 patients with unilateral or bilateral knee pain diagnosed as primary osteoarthritis of knee were included in this study. Musculoskeletal ultrasonography was performed on all patients to look for the presence of Baker's cyst. The incidence of Baker's cyst was the primary outcome of this study. Depending upon the presence/ absence of Baker's cyst, two groups were formed, and variables were compared between these groups to find the factors associated with Baker's cyst. Statistical analysis was done using student t-test, ANOVA test and Chi-square test. Result The incidence of Baker's cyst in this study was 21.1% of the patients and 89.28% were asymptomatic. Baker's cysts were strongly associated with joint effusion and synovial hypertrophy. Conclusion Baker's cyst was a common finding in the patient with knee osteoarthritis. Musculoskeletal ultrasound would be a valuable tool to detect such asymptomatic cysts early.
膝关节疼痛和关节活动受限是疼痛门诊中因膝关节骨关节炎而常见的主诉，且常与腘窝囊肿相关。这些囊肿在初始阶段通常无症状，在临床检查时可能被漏诊，随后可能以复杂的形式出现。肌肉骨骼超声检查可能有助于在疾病早期发现无症状的腘窝囊肿。目的：在对患者进行临床评估时，借助膝关节常规肌肉骨骼超声检查观察膝关节原发性骨关节炎患者腘窝囊肿的发生率。方法：本研究共纳入114例诊断为膝关节原发性骨关节炎的单侧或双侧膝关节疼痛患者。对所有患者进行肌肉骨骼超声检查以寻找腘窝囊肿的存在。腘窝囊肿的发生率是本研究的主要结果。根据腘窝囊肿的有无形成两组，并比较两组之间的变量以找出与腘窝囊肿相关的因素。使用学生t检验、方差分析和卡方检验进行统计分析。结果：本研究中腘窝囊肿的发生率为患者的21.1%，89.28%的囊肿无症状。腘窝囊肿与关节积液和滑膜肥厚密切相关。结论：腘窝囊肿在膝关节骨关节炎患者中是常见发现。肌肉骨骼超声将是早期检测此类无症状囊肿的有价值工具。
