The Knee Score consists of points given for pain, range of motion, and stability in both the coronal and sagittal planes, with deductions for fixed deformity, and extensor lag. The Function Score consists of points given for the ability to walk on level surfaces, and the ability to ascend and descend stairs, with deductions for the use of external supporting devices.
