Why do i have to go to an orthopaedic clinic if i just got stitches?

May not have to: It really depends on the location of the injury and whether or not their is any suspicion of additional injuries (tendon, nerve etc.) if it is just a superficial laceration, then your primary care doc should be fine for suture removal.

See below : You may have had an associated bone muscle tendon ligament nerve or artery injury concomitantly. Follow-up is recommended as prescribed by the referring physician. good luck thank you
