Abstract

Aim: The aim of the study was to demonstrate a surgical technique and evaluate the early outcome of a knee joint meniscal scaffold implantation. Patients and methods: During the time period between years 2016 and 2020, in our hospital nine Actifit meniscal scaffolds were implanted into the knee joint of nine different patients. The treatment outcome analysis was performed in 7 patients with the median age of 36 (IQR 10.5) years. The median follow-up was 25 (IQR 28.5) months. Before the surgery, and at the end of the study, functional testing was performed using Lysholm, Tegner and VAS questionnaires. All patients underwent MRI checkups at 3, 6, 12, 24 and 30 months after the surgery. Meniscal implants were evaluated using the criteria of Genovese. Results: The median Lysholm score before the meniscal scaffold implantation was 61 (IQR 10), and after it was 90 (IQR 13.0) (p=0.011). The median Tegner functional questionnaire score before the meniscal scaffold implantation was 4 (IQR 0.5), while after the surgery score went up to 5 (IQR 0.5) (p=0.059). The median preoperative VAS score was 3 (IQR 1.0), and the postoperative score was 8 (IQR 0.5) (p=0.011). At 3 months follow-up, 6 (86%) patients showed a moderate meniscal extrusion (Genovese type 2), with no further progression. The MRI analysis showed the meniscal scaffold vascularization, even with the loss of morphology and volume as well as implant extrusion. Conclusion: In short follow-up after the meniscal scaffold implantation, till now there has been no progression found of chondral damage in femorotibial joint, with concurrent significant functional improvement.
