NOTE. Because of rounding when the final calculation was performed, calculations based on preoperative and postoperative mean values may not equal the mean change or percent change values presented.
↵* Percentages are not indicative of total improvement because patients reached the maximum value.
↵† Patients were unable to complete the task because of an unrelated injury or data were missed during collection.
