In managing knee osteoarthritis through exercise, which approach is recommended?

• A. Increase high-impact activities to build endurance.
• B. Focus on improving quadriceps and hip strength with low-impact aerobic exercise.
• C. Avoid resistance training entirely.
• D. Begin with maximal ROM and stretching.

Answer: (B)

In knee osteoarthritis, the most effective exercise approach focuses on strengthening the muscles around the knee and hip while incorporating low‑impact cardio to protect the joint. Building the quadriceps and hip stabilizers improves knee alignment, reduces abnormal joint loading during movement, and tends to lessen pain while boosting function. Low‑impact activities such as walking, cycling, swimming, or using an elliptical provide endurance benefits and help with weight management without overstressing the knee. High‑impact activities increase repetitive joint stress and are not ideal as the primary strategy. Resistance training is important and should start with light loads and progress gradually. Flexibility work matters too, but beginning with maximal range of motion and stretching alone doesn’t address the essential strength deficits or optimize improvement.
