Results of polyurethane implant for persistent knee pain after partial meniscectomy with a minimum of two years follow-up

PURPOSETo present the results of a polyurethane meniscal scaffold implant in 10 patients with persistent pain after meniscectomy.METHODSProspective, descriptive study of ten patients who underwent arthroscopic implantation of a polyurethane meniscal scaffold. Functional, MRI, and radiography assessment was performed pre-operatively and at 6-months, 1-year, and a final follow-up at a minimum of two years. Clinical evaluation included Lysholm score, KOOS and VAS. The MRI morphology and signal intensity of the implant were evaluated according to the criteria of Genovese et al.RESULTSStatistically significant differences were found between the mean Lysholm score before surgery (63.5 points), and that at 6 months (76.8 points) (p=.001), one year (83.3 points) (p
