* BACKGROUND: Matrix-induced autologous chondrocyte implantation (MACI) is an effective surgical procedure to repair defective cartilage. * CASE PRESENTATION: This case study examined the influence of an isokinetic training program on muscle strength, size, and vertical jump performance for a young female adult after a MACI procedure. The subject completed an isokinetic training program 3 days/week for 12 weeks. Weekly assessments included isometric and isokinetic assessments of thigh muscle strength and power, ultrasound assessments of quadriceps and hamstrings muscle size, and force plate assessments of bilateral and unilateral vertical jump performance. * OUTCOME AND FOLLOW-UP: Thigh muscle size 15% to 23%. Thigh muscle strength increased from 19% to 105%, whereas power increased from 29% to 121%. Bilateral and unilateral vertical jump performance increased from 6% to 93%. * DISCUSSION: This study demonstrates that a 12-week isokinetic training program appears effective for increasing muscle strength, size, and vertical jump performance within the year following a MACI procedure.
