Abstract Neoplastic and non-neoplastic lesions occur commonly in the bones of the knee. For certain tumours, it is the most frequent location, and it is also a common site for neoplasms and non-neoplastic tumour mimics that do not demonstrate a particular anatomic preference. Lesions may arise at the end of the bone (subarticular) or in the metaphysis and extend towards the joint. Tumours and tumour mimics occurring in subarticular locations or extending from the metaphysis are considered separately in this review. We have included lesions that we expect will be identifiable on routine knee MRI examinations.
