NOTE. The following variables were also found to be insignificant on Cox regression and were, thus, excluded from the table above: sex, age, workers’ compensation, body mass index, smoking status, hypertension, thyroid disease, symptom duration, pre-existing arthritis, oblique tears, horizontal tears, root tears, flap tears, chondroplasty, subsequent procedures.
Cells left blank denote nonsignificant relationships.
IKDC, International Knee Documentation Committee Score; KOOS: Knee Injury and Osteoarthritis Outcome Score; JR, joint replacement; PASS, patient acceptable symptomatic state; PS, Physical Function Short Form; Sx, symptoms; ADL, activities of daily living; QOL: quality of life.
