Outcome

IKDC

(Total score / 87) x 100

 Limb Symmetry Index:

A limb symmetry index will be calculated from the average of 3 trials as the involved limb hop distance divided by the involved limb hop distance, multiplied by 100.

Tuck Jump Assessment:

Athletes perform repeated tuck jumps for 10 seconds while the clinician scores the performance for each category from frontal and sagittal planes (Myer et al, 2006).

TUCK JUMP ASSESSMENT YES NO COMMENTS
Knee and Thigh Motion
- Lower extremity valgus at landing      
- Thighs do not reach parallel (peak of jump)      
- Thighs do not equal side to side (during flight)      
Foot Position During Landing
- Foot placement not shoulder width apart      
- Foot placement not parallel (front to back)      
- Foot contact timing not equal      
- Excessive landing contact noise      
Plyometric Technique
- Pause between jumps      
- Technique declines prior to 10 seconds      
- Does not land in same footprint

(excessive in flight motion)

Subjective Evaluation:

Patient reported outcome measures will be completed after all objective clinical measures have been collected

Follow up measures

To assist with the long term validity of the ARTS program, three subjective assessments will be conducted intermittently at the initial consult; testing for progression; and 12 months; 2 years; and 5 years following injury.

IKDC Subjective Knee Evaluation Form:

The IKDC was selected due to the strong focus on patient reported outcomes which reflect the concerns of athletes (Hambly & Konstandina, 2010)

Tegner activity grading scale:

Quantifies activity levels related to both work and sports in patients with ACL ruptures. A reliable tool to determine whether athletes return to previous levels of physical activity (Briggs et al, 2009).

Tampa Scale for Kinesiophobia (TSK-11):

Measures the pain-related fear associated with movement and re-injury. Increased levels of function have been associated with reduced levels of fear avoidance during ACL rehabilitation (Chmielewski et al, 2008).
