Sarah, a 58-year-old primary school teacher, had always been an active and energetic individual. Her days were filled with teaching lively classrooms, gardening in her spare time and walking her beloved dog. However, over the years, Sarah began to notice a persistent ache in her right knee. What started as occasional discomfort gradually worsened into severe pain that affected her daily life. Tasks like climbing stairs, kneeling to help her students, or even standing for long periods became unbearable.
Sarah was diagnosed with osteoarthritis in her right knee, a condition that had progressed to the point where non-surgical treatments like physiotherapy and pain relief medication were no longer effective. Her mobility was significantly impacted and she found herself unable to enjoy her usual activities.
