If hypermobility causes osteoarthritis is it primary or secondary oa?

Secondary: Several studies have shown significant association between diffuse joint hypermobility and osteoarthritis. Joint hypermobility predisposes to musculoskeletal disorders, especially osteoarthritis. Laxity of the joints has been predisposing factor for joint or soft tissue injury.

Arthralgia vs OA: Some studies suggest the relationship between hypermobility and joint arthralgia. There are yet to be any randomized studies that connect osteoarthritis to hypermobility. Early oa occurs in patients with chronic acl tears. This is supported by evidence and would seem to support this theory. Recent studies have indicated that the oa is related to cartilage damage at the time of the original injury.
