UNCERTAINTY: Does the amount or type of joint abnormality seen in the early stages of OA have impact on outcome? (JLA PSP Other Priority 10)
Overall ranking amongst other questions	10
JLA question ID	0041/30
Extra explanatory note	Not available
Evidence	None identified
Health Research Classification System category	Musculoskeletal

Extra information provided by this PSP
Original uncertainty examples	Does the shape of the affected joint equate with severity of the structural disease? ~ Does the shape of the affected joint correlate with the severity of the arthritis? ~ There is a perception amongst clinicians that varus or valgus deformities or moment forces may accelerate cartilage loss. This perception doesn't appear to be evidence based, however there is little evidence to discount this view. (Continues - Notes)
