What's the best supplement/medication/tablets etc to help and prevent arthritis in the hip (previously had perthes disease). i appreciate your help.

Some people say!: Glucosamine and chondroitin sulfate, maybe. Sam-e, maybe. Hard science is still quite undecided. These are expensive supplements. See if they work for you.

Perthes Disease: For cartilage health for your hip i would recommend glucosamine supplementation. Also for quality of production i would recommend that you use the brand names osteobiflex or cosamin ds. In a double blinded study in the late 1990's on USN seals with know arthritis that used glucosomine supplementation 50% on study members became pain free within 2 months on the glucosamin.
