At an young age of 35 yrs Arthritis is very uncommon .Please meet an Orthopaedician and get x-rays and if needed MRI scans which will tell you what is wrong and guide for further management. Looking at your story probably you have meniscal/ patellofemoral changes which might be helped by Arthroscopic intervention.
