Primary Outcome Measures

Name	Time	Method
Mechanical axis	Change from baseline mechanical axis at 6 weeks after surgery	Post-operative Mechanical Alignment; Hip-Knee-Ankle angle; If you divide the knee into quadrants, the ideal mechanical axis would bisect the knee (0), with medial zone (-1) or lateral zone (-1) being within physiologic range. With the notable exception of physiologic varus \<age 2 and physiologic valgus \<age 6, medial or lateral zones 2 or 3 would likely manifest symptoms and gait disturbance and thereby warrant surgical intervention

Secondary Outcome Measures

Name	Time	Method
Knee Society and Knee Society function score	Change from baseline Knee Society and Knee Society function score at 3 months, 6 months, and 12 months after surgery	Knee Society and Knee Society function score (minimum 0, maximum 200)
Range of motion of knee	Change from baseline Range of motion of knee at 3 months, 6 months, and 12 months after surgery	Range of motion of knee (minimum 0, maximum 140)
Oxford knee score	Change from baseline Oxford knee score 3 months, 6 months, and 12 months after surgery	Oxford knee score (minimum 0, maximum 48)
