<jats:title>Introduction</jats:title>
<jats:p>The aim of the present study was to evaluate midterm outcomes 5–7 years after matrix-associated autologous chondrocyte implantation (MACI) in the patellofemoral joint.</jats:p>

<jats:title>Materials and methods</jats:title>
<jats:p>Twenty-six patients who had undergone MACI using the Novocart® 3D scaffold were prospectively evaluated. Clinical outcomes were determined by measuring the 36-Item Short-Form Health Survey (SF-36) and International Knee Documentation Committee (IKDC) scores and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) values preoperatively and 3, 6, and 12 months, and a mean of 6 years postoperatively. At the final follow-up, the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score was evaluated.</jats:p>

<jats:title>Results</jats:title>
<jats:p>Twenty-two patients with 23 focal cartilage defects (19 patella and four trochlea) were available for the final follow-up. The mean defect size was 4.0 ± 1.9 cm<jats:sup>2</jats:sup> (range 2.4–9.4 cm<jats:sup>2</jats:sup>). All clinical outcome scores improved significantly until 5–7 years after MACI (SF-36 score, 61.2 ± 19.6 to 83.2 ± 11.6; <jats:italic>P</jats:italic> = 0.001; IKDC score, 47.5 ± 20.6 to 74.7 ± 15.5; <jats:italic>P</jats:italic> < 0.001; and WOMAC, 29.8 ± 15.7 to 8.2 ± 10.3; <jats:italic>P</jats:italic> < 0.001). The mean MOCART score was 76.0 ± 11.0 at the final follow-up. Nineteen of the 22 patients (86.4%) were satisfied with the outcomes after 5–7 years and responded that they would undergo the procedure again.</jats:p>

<jats:title>Conclusion</jats:title>
<jats:p>MACI in the patellofemoral joint demonstrated good midterm clinical results with a significant reduction in pain, improvement in function, and high patient satisfaction. These clinical findings are supported by radiological evidence from MOCART scores.</jats:p>
