To identify those clinical characteristic and arthroscopic findings in patients with knee arthrosis that are associated with worsening of the disease and subsequent total knee arthroplasty (TKA).A retrospective, descriptive study was conducted on 78 consecutive patients (88 knees) who underwent knee arthroscopy for arthrosis. The study included 44 women and 34 men, with a mean age of 58.9 years (range: 37-78 years). After a mean follow-up of 50.4 months (range: 12-96 months), those patients who progressed towards TKA were identified. A logistic regression model was applied to recognise the factors associated with deterioration of the arthrosis, with consequent progression towards a TKA.Twenty-four out of the 88 knees progressed towards a TKA (27.3%) within a mean time of 13.5 months after arthroscopy (range: 13-29 months). The clinical characteristics that showed a significant association with poor progression of the arthrosis were: female gender (0.02) and Ahlbäck 2 (P=.04). Arthroscopic finding that proved significant correlation with worsening of the arthrosis towards TKA were: meniscal tears of the posterior horn (P=.02), meniscectomies above 60% (P=.03), and 2nd degree chondral lesions in loading areas of the medial femoral condyle (P=.02).The variables associated with a greater chance of progressing towards a TKA after a knee arthroscopy due to arthrosis in this study were, female gender, grade 2 radiographic arthrosis, posterior horn meniscal lesions, meniscectomies over 60%, and chondral lesions in loading area of the medial femoral condyle.
