A member asked:

My leg/knee won't straighten. have diagnosis of psoriatic arthritis but what can i do to get leg to work properly?

A doctor has provided 1 answer

Need evaluation: Sometimes when the knee "locks" or cannot straighten out fully, it means that there may be a tear in the cartilage (meniscus) preventing the knee from straightening. See an orthopedist or a physiatrist ( rehab medicine specialist) and he/she should be able to help you with it.
