hello You must consult an orthopedic doctor alongwith fresh x rays of knee and leg for evaluation.If bracing has not helped a review is required maybe percutaneouuuus fixingg of tibial plateau may be required if it has not displaced, or elsee, an open internal fixation after reduction.Swelling and pain indicate healing is incomplete amybe x ray doesnt show any displacement, but union may be delayed and incomplete. Internal fixation will prevent risks for displacement and relieve pain and swelling.For six weeks rest to leg is necessary. Some surgeons prefer to apply plaster cast casing for undisplaced fracture and you may be required to stay in bed for six weeks consult for the options thanks
