Brief description of the measure: Percentage of patients 18 years of age and older who obtained at least a 10% improvement in knee pain and/or function as measured by validated patient-reported outcome measures (PROMs) completed up to 90 days prior to and 9 to 15 months after undergoing primary total knee arthroplasty (TKA) surgery. PROMs include any validated measures of knee-related measures of pain and/or function, such as KOOS-Pain, KOOS-ADL, KOOS-PS, and KOOS-JR..
DENOMINATOR: All patients 18 years of age and older undergoing elective primary TKA surgery who completed knee-related PROMs (e.g., KOOS-Pain, KOOS-ADL, KOOS-PS, KOOS-JR) to measure knee pain and/or function up to 90 days prior to and 9-15 months after the surgery.
NUMERATOR: Patients whose knee pain and/or function scores at 9-15 months post-op improved by at least 10% (e.g., 10 points on a 100-point scale) from baseline.
DENOMINATOR Exclusions: Patients under 18 years of age; emergent (non-elective) TKA; revision TKA surgery; knee pain and/or function PROMs not completed up to 90 days prior to and 9-15 months after surgery.
