Purpose:
To carry out a modern diagnostic survey among patients with a clinical and radiological diagnosis of early osteoarthritis of the knee.
Materials And Methods:
A magnetic resonance imaging survey was performed on 70 patients (82 knees) with a mean age of 59 years. (range, 40-71 years) who had chronic knee pain, clinical diagnosis of early osteoarthritis of the knee and conventional knee radiographs classified as 1 and 2 on the Kellgren-Lawrence scale.
Results:
A variety of different disorders was found; degenerative meniscal lesions with or without ruptures of the anterior cruciate ligament in 70.7% of the knees, osteonecrosis of the femoral and tibial condyles in 9.75%, osteophytes and degenerative articular cartilage lesions in 8.54%, transient osteoporosis in 2.44% and benign neoplasms and cysts in 6.1%.
Conclusions:
The existence of such a heterogenous group of disorders in these "early osteoarthritic knees" may explain failures in treatment and it may justify a modern MRI imaging approach to proper diagnosis.
