Isolated lateral patellofemoral joint OA more common than isolated medial counterpart

Among symptomatic patients who were at least 50 years old, investigators found isolated lateral patellofemoral joint osteoarthritis was more common than isolated medial patellofemoral joint osteoarthritis and was more often linked with osteoarthritis risk factors. Vincent Ukachukwu, MRCGP, MMedSci, from Keele University in the United Kingdom, and colleagues assessed 745 adults with symptomatic osteoarthritis (OA). They found isolated lateral PF joint OA was more common than its medial counterpart. In addition, increased risk for isolated lateral joint space narrowing (JSN) was linked with age (ratio = 1.19), BMI (ratio = 1.15) and valgus misalignment (ratio = 2.58); whereas, isolated medial JSN was only linked with age (ratio = 1.2). Furthermore, isolated lateral patellofemoral (PF) joint OA was linked with higher pain scores than the medial counterpart, but these results were not significant.
