Osteoarthritis and Paget's disease

Area of Science:

• Rheumatology
• Orthopedics
• Bone Metabolism

Background:

• Paget's disease of bone near joints is hypothesized to accelerate osteoarthritis.
• Osteoarthritis development may be influenced by a patient's inherent predisposition.

Purpose of the Study:

• To investigate the relationship between Paget's disease affecting joint margins and the severity of adjacent osteoarthritis.
• To explore if a general tendency for osteoarthritis modifies the impact of Paget's disease on a specific joint.

Main Methods:

• Clinical and radiographic examination of 69 patients with Paget's disease involving joint margins.
• Radiographic scoring using the Kellgren and Lawrence method for 100 affected joints (hips, knees, wrist).

Main Results:

• Osteoarthritis was significantly more severe in joints ipsilateral to Paget's disease compared to contralateral joints (P=0.04).
• Joints with Paget's disease showed more severe osteoarthritis if the patient had osteoarthritis elsewhere (P=0.01).

Conclusions:

• Paget's disease adjacent to joints is associated with accelerated osteoarthritis, though selection bias might inflate this effect.
• The severity of osteoarthritis in Paget's-affected joints correlates with the presence of osteoarthritis in other body areas.
• Further research is needed to quantify the precise impact of Paget's disease on adjacent joints.
