Hello, I have studied your case. Long term studies are not available with krill oil. No scientific data for arthritis benefit. Precaution to be taken Activity modifications-avoid squatting, avoid cross leg sitting on floor, and reduce stair climbing. Weight reduction is very important to prevent progression. Do daily exercises and stretches. Diet rich in calcium and vitaminD will help to reduce progression. Hope this answers your query.
