Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Weight-bearing lower extremity kinematics	Hip flexion/extension, knee flexion/extension, and ankle dorsiflexion/plantar flexion; measured through optical motion tracking software	Measured during gait assessment on post-operative day 4-12
Other	Torso kinematics	Thoracic flexion/extension; measured through optical motion tracking software	Measured during gait assessment on post-operative day 4-12
Other	Spatiotemporal parameters	Gait velocity, crutch stride length, weight-bearing lower extremity stride length; measured through timing lights and computer software	Measured during gait assessment on post-operative day 4-12
Other	Crutch comfort	Measured through an 11-point Numerical Rating Scale for both crutch types (0 = extremely uncomfortable, 10 = extremely comfortable)	Measured during gait assessment on post-operative day 4-12
Other	Number of falls		Measured at 4 weeks post-operation
Primary	Range of scapular downward rotation		Measured during gait assessment on post-operative day 4-12
Secondary	Bilateral upper extremity kinematics	Hip flexion/extension, knee flexion/extension, and ankle dorsiflexion/plantar flexion; measured through optical motion tracking software	Measured during gait assessment on post-operative day 4-12
Secondary	Bilateral upper extremity electromyographic (EMG) activity		Measured during gait assessment on post-operative day 4-12
Secondary	Upper extremity pain	Measurements of pain at the shoulder, elbow, and wrist using an 11-point Numerical Rating Scale (0 = no pain, 10 = extreme pain)	Measured at 3 time points: pre-operative, during gait assessment, and 4 weeks post-operative
