Outcomes
Primary Outcomes
Mechanical axis
Time Frame: 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 Outcomes
- 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)
- Range of motion of knee(Change from baseline Range of motion of knee at 3 months, 6 months, and 12 months after surgery)
- Oxford knee score(Change from baseline Oxford knee score 3 months, 6 months, and 12 months after surgery)
