*
The Rasmussen score assesses articular subsidence (none, <6 mm, 6 to 10 mm), condylar widening (none, <6 mm, 6 to 10 mm), and varus or valgus deviation (none, <10°, 10° to 20°), which allows for grading the outcomes in excellent, good, fair, or poor.
†The values are given as the number of patients, with the percentage in parentheses.
