Collagen meniscus implant (CMI) was performed on 50 patients, who were affected by irreparable meniscal lesions or had previously undergone partial medial meniscectomy. Additional procedures included 16 ACL reconstruction, 8 high tibial osteotomy and 2 autologous chondrocyte implantation. All knees were evaluated according to the Lysholm II and Tegner activity scales. MRI was performed 6, 12 and 24 months postoperatively. Follow up averaged 15.7 (6-31) months. At most recent evaluation, 46 patients showed improvement of the clinical scores. MRI was useful to document tissue invasion and ingrowth inside the scaffold: a progression toward a more homogeneous signal was detected in the implants with a two-year follow-up. Clinical results achieved with CMI are promising, once correct indications are respected and patients are compliant with rehabilitation program.

Abstract
Collagen meniscus implant (CMI) was performed on 50 patients, who were affected by irreparable meniscal lesions or had previously undergone partial medial meniscectomy. Additional procedures included 16 ACL reconstruction, 8 high tibial osteotomy and 2 autologous chondrocyte implantation. All knees were evaluated according to the Lysholm II and Tegner activity scales. MRI was performed 6, 12 and 24 months postoperatively. Follow up averaged 15.7 (6-31) months. At most recent evaluation, 46 patients showed improvement of the clinical scores. MRI was useful to document tissue invasion and ingrowth inside the scaffold: a progression toward a more homogeneous signal was detected in the implants with a two-year follow-up. Clinical results achieved with CMI are promising, once correct indications are respected and patients are compliant with rehabilitation program.
