A 66-year-old female presented with progressive pain in her hands and right knee over the past year. She reported using acetaminophen for pain relief, but her symptoms worsened over the past two months. Additionally, she complained of stiffness in her hands and right knee, lasting for about 15 minutes every morning after waking up. The patient has a medical history of hypertension for the past five years and underwent cholecystectomy two years ago. Despite being physically active, her increasing pain limits her ability to perform activities. During the physical examination, tenderness and swelling of the distal interphalangeal joints of the index and middle fingers were observed when the extension of the knee joint and finger joints was performed. Although her vitals were normal, except for a blood pressure of 140/90 mmHg and a BMI of 35 kg/m², osteoarthritis was considered a possible underlying condition based on these findings.
