Abstract
In acquired knee deformations the usefulness of arthroscopy is strictly correlated with the degree of axial defomation and cartilaginous degeneration. The authors comparatively consider two groups of patients (the first one Albach I and II and the second one Albach III and IV) treated with arthroscopic débridement (washing and curettage), in relation to the joint’s degeneration stage. A minimum 6-month follow-up, using KSKSS grading revealed satisfactory medium-term results.
