摘要：TO DETERMINE THE WAY A PATIENT’S ACTIVITY LEVEL INFLUENCES THECHARACTERISTICS OF CHONDRAL LESIONS OBSERVED DURING KNEEARTHROSCOPY.MATERIAL AND METHOD: THE STUDY IS BASED ON THE RETROSPECTIVEANALYSIS OF 420 PATIENTS WHO UNDERWENT ARTHROSCOPIC INTERVENTIONSON THE KNEE DURING JANUARY 2011 AND DECEMBER 2013. WE USED DATAOBTAINED FROM THE PATIENT RECORDS AND INFORMATION ABOUT THEOBSERVED CARTILAGE LESIONS OF THE KNEE FROM THE SURGICAL PROTOCOLS,WHICH WE SUBSEQUENTLY CORRELATED WITH THE ACTIVITY LEVEL OFPATIENTS BASED ON THEIR ESTIMATES USING THE TEGNER ACTIVITY SCALE.RESULTS: THE MEAN AGE OF PATIENTS WAS 32.6 YEARS (16 TO 53 YEARS), 269PATIENTS WERE MALE (64.04%) AND 151 FEMALE (35.96%). THE ACTIVITY LEVELACCORDING TO THE TEGNER SCALE RANGED FROM 0-1 IN 10.96% OF PATIENTS,FROM 2 TO 4 IN 21.90%, FROM 5 TO 7 IN 42.86% AND FROM 8 TO 10 IN 24.28% OFTHE PATIENTS. MILD OR MODERATE CARTILAGE LESIONS WERE PRESENT INMOST CASES: ICRS I IN 82.14% AND ICRS II IN 60.47% OF PATIENTS. ICR III LESIONSWERE PRESENT IN 27.14% OF CASES, WHILE ICRS IV LESIONS WERE FOUND IN15.23% OF CASES. SINGLE FOCAL LESIONS WERE RECORDED IN 25.95% OF THE PATIENTS AND MULTIPLE AND/ OR EXTENDED LESIONS WERE OBSERVED IN63.09% OF THE TOTAL CASES. WE FOUND A STRONG POSITIVE CORRELATIONBETWEEN PATIENT ACTIVITY LEVEL AND THE NUMBER AND EXTENT OFCARTILAGE LESIONS (R = 0.77 AND R = 0.81, P <0.01), WITH A MODERATECORRELATION BETWEEN ACTIVITY LEVEL AND THE SEVERITY OF CHONDRALLESIONS.
