Explanation:

The main diagnosis of knee osteoarthritis is based on the patient's age, symptoms (chronic pain and stiffness worsened by weight - bearing), and physical examination findings (joint crepitus, limited range of motion, localized swelling). Recommendations include imaging (X - rays first to look for joint space narrowing, subchondral sclerosis/cysts, osteophytes, and then MRI if needed), lab tests (RF just in case), and referrals to an orthopedic surgeon if necessary and physical therapy.

Answer:

1. Main diagnosis: Osteoarthritis of the knee due to age, chronic pain/stiffness with weight - bearing, and classic physical exam features.

• Imaging: X - rays of the knee to check for joint space narrowing, subchondral sclerosis/cysts, osteophytes; MRI after X - ray findings.
• Labs: RF (just in case).
• Referral: Orthopedic surgeon if needed; Physical therapy.
