Abstract

Background. Subchondral insufficiency fracture of the knee (SIFK) is a frequent cause of knee joint pain in patients over 55 years of age. Diagnosis of this pathology at an early stage has certain difficulties, as it requires magnetic resonance imaging (MRI). Aim of the study. To determine the relationship between the size of the lesion in subchondral insufficiency fracture of the knee joint, the patient's body mass index and the risk of articular surface collapse. Material and Methods. In 35 female patients with subchondral insufficiency fracture the size of the lesion in frontal and sagittal planes, as well as its volume according to MRI were determined. The obtained results made it possible to assess the risk of articular surface collapse. Results. The study revealed a relationship between the size of the lesion and the risk of articular surface collapse in subchondral insufficiency fracture of the knee. An anteroposterior size of the lesion of more than 14.1 mm, a transverse size of more than 10.2 mm, and a craniocaudal size of more than 1.22 mm are risk factors for subsequent articular surface collapse and progression of osteoarthritis of the knee joint. The analysis of the correlation between body mass index (BMI) and the development of articular surface collapse found no specific BMI value associated with articular surface collapse. Conclusions. A risk factor for articular surface collapse in patients with subchondral bone insufficiency fracture of the knee joint was determined, which allows predicting the outcomes of the disease treatment. Body mass index and the development of articular surface collapse do not correlate with each other.
