What it measures:

The Cincinnati Knee Rating System (CKRS) is a questionnaire and functional assessment used to assess knee function. The CKRS was developed to assess the knee function treatment outcome in patients 17 to 54 years of age exhibiting a chronic anterior cruciate ligament (ACL) deficient knee (Barber-Westin & Noyes, 2015).  It has also been validated for the use in patients who have undergone other operative procedures such as articular cartilage restorative procedures, meniscus repairs or transplants, osteotomies, or patellofemoral procedures (Noyes, Westin and Rankin 2004). 

The CKRS measures pain, results of ACL reconstruction, knee stability, patient perception of condition, function in sport and activities of daily living, joint integrity, knee swelling, knee range of motion, and lower limb symmetry. It has seven components including: subjective assessment (Symptom Rating Scale, Patient Perception of the Overall Knee Condition Scale, Sports Activity Scale, Rating of Individual Sports and Daily Activity Functions, Occupational Rating Scale), patient history, knee examination, objective testing, operative procedures and articular cartilage rating, postoperative complications, and overall rating. 

Target Population:

This summary includes information on the use of this test in patients with varying diagnoses of knee pathologies, including: ACL injury, patellofemoral disorders, instability, meniscal, ligamentous, and osteochondritis dissecans. Males and females with ages ranging from 13-65.
