Differential Diagnosis for Right Hip and Knee Pain
Single Most Likely Diagnosis
- Osteoarthritis: This is a common condition that affects the joints, causing pain and stiffness. The hip and knee are frequently affected, and the pain can be exacerbated by weight-bearing activities.
Other Likely Diagnoses
- Tendinitis or bursitis: Inflammation of the tendons or bursae around the hip and knee can cause pain and stiffness.
- Ligament sprain: A sprain of the ligaments surrounding the hip or knee can cause pain and instability.
- Meniscal tear: A tear in the cartilage of the knee can cause pain, stiffness, and locking of the joint.
- Hip or knee strain: A strain of the muscles around the hip or knee can cause pain and stiffness.
Do Not Miss Diagnoses
- Septic arthritis: A bacterial infection of the joint can cause severe pain, swelling, and fever. If left untreated, it can lead to joint destruction and systemic infection.
- Avascular necrosis: A loss of blood supply to the bone can cause pain and collapse of the bone. If left untreated, it can lead to severe arthritis and disability.
- Fracture: A break in the bone can cause severe pain and instability. If left untreated, it can lead to malunion, nonunion, or avascular necrosis.
- Deep vein thrombosis: A blood clot in the deep veins can cause pain, swelling, and warmth in the affected leg. If left untreated, it can lead to pulmonary embolism and death.
Rare Diagnoses
- Osteonecrosis: A rare condition that causes death of bone tissue due to lack of blood supply.
- Synovial chondromatosis: A rare condition that causes growth of cartilage in the joint, leading to pain and stiffness.
- Pigmented villonodular synovitis: A rare condition that causes growth of tissue in the joint, leading to pain and stiffness.
- Bone tumor: A rare condition that causes growth of abnormal tissue in the bone, leading to pain and weakness.
