A 6-year-old girl presents to the orthopaedic clinic 3 weeks after a supracondylar fracture of the humerus that was treated with closed reduction and percutaneous pinning. The fracture has healed well on X-ray, and the pins have been removed. On examination, she has 15° loss of elbow extension compared to the contralateral side. The parents are concerned about her ability to play sports. What is the most appropriate counseling regarding long-term functional outcome?
