Background Injuries to the articular cartilage in the knee are common in jumping athletes, particularly high‐level basketball players. Unfortunately, these are often diagnosed at a late stage of the disease process, after tissue loss has already occurred. Purpose/Hypothesis To evaluate longitudinal changes in knee articular cartilage and knee function in National Collegiate Athletic Association (NCAA) basketball players and their evolution over the competitive season and off‐season. Study Type Longitudinal, multisite cohort study. Population Thirty‐two NCAA Division 1 athletes: 22 basketball players and 10 swimmers. Field Strength/Sequence Bilateral magnetic resonance imaging (MRI) using a combined T 1ρ and T 2 magnetization‐prepared angle‐modulated portioned k‐space spoiled gradient‐echo snapshots (MAPSS) sequence at 3T. Assessment We calculated T 2 and T 1ρ relaxation times to compare compositional cartilage changes between three timepoints: preseason 1, postseason 1, and preseason 2. Knee Osteoarthritis Outcome Scores (KOOS) were used to assess knee health. Statistical Tests One‐way variance model hypothesis test, general linear model, and chi‐squared test. Results In the femoral articular cartilage of all athletes, we saw a global decrease in T 2 and T 1ρ relaxation times during the competitive season (all P < 0.05) and an increase in T 2 and T 1ρ relaxation times during the off‐season (all P < 0.05). In the basketball players' femoral cartilage, the anterior and ce...
