Description
Yi Hua, Hua Wang, and Xu Yang published a 2026 radiological study comparing recurrent kneecap dislocation in patients whose skeletons are still growing with those fully mature. Anatomy decides much of this injury's risk, and children's anatomy differs from adults'. Records covered 85 patients and 106 knees treated between 2016 and 2024, split by whether the growth plates had closed. Scans measured kneecap height, groove shape, kneecap shape, tilt, and leg rotation.
Immature patients, averaging thirteen and a half, had strikingly higher kneecaps: their height index averaged 1.5 against 1.3 in adults, and a high kneecap appeared in about eighty-five percent of young knees. Young patients also showed more kneecap tilt and more inward thigh rotation, yet their kneecap shape was less severely malformed than adults'. Growth stage therefore changes which anatomical faults dominate, with implications for choosing corrective surgery.
