Nina (71 years old)

Nina, aged 71, is a retired teacher who enjoys occasional sightseeing of historical monuments.

Besides being overweight (BMI: 28), she has no notable medical history and does not smoke nor drinks alcohol.

Over the past 5 years, her motility has progressively decreased due to increasing joint pain in her hips and knees. At first, she managed the pain by occasionally taking over-the-counter NSAIDs, but due to worsening of her condition, she now presents to your clinic.
