Hip Arthritis Pain Distribution and Management

Typical Pain Patterns in Hip Arthritis

The primary symptom of hip arthritis is often pain in the groin area that may radiate to the buttock or thigh, according to the American Academy of Orthopaedic Surgeons 1, 2
Pain is typically exacerbated with activity and alleviated with rest, with progressive worsening over time, as reported by the American Academy of Orthopaedic Surgeons 3
Internal rotation of the affected hip often reproduces the patient's pain during physical examination, as noted by the American Academy of Orthopaedic Surgeons 3

The complex anatomy of the hip joint means that articular cartilage damage in weight-bearing areas can cause pain that radiates beyond the immediate joint area, according to the American Academy of Orthopaedic Surgeons 1

Labral tears can present with similar symptoms to hip arthritis, including groin pain radiating to the buttock, as reported by the American Academy of Orthopaedic Surgeons and the British Journal of Sports Medicine 1, 4
Femoroacetabular impingement (FAI) syndrome typically presents with groin pain that may also radiate to the buttock or thigh, according to the British Journal of Sports Medicine 4, 5
Referred pain from the lumbar spine or sacroiliac joints can mimic hip pain, as noted by the American College of Radiology 6, 7

Plain radiographs are the recommended first imaging step for evaluating hip pain and can often diagnose arthritis, according to the American College of Radiology 6, 7
MRI without contrast is the most appropriate next imaging study when radiographs are inconclusive but clinical suspicion for hip pathology remains high, as recommended by the American College of Radiology 6
Intra-articular anesthetic injection can be both diagnostic and therapeutic, providing temporary relief for hip arthritis pain, according to the American College of Radiology 7
Physical examination findings such as pain with internal rotation and limited range of motion support the diagnosis of hip arthritis, as reported by the American Academy of Orthopaedic Surgeons 3

Initial management includes NSAIDs (strong recommendation) and physical therapy (moderate recommendation), as recommended by the American Academy of Orthopaedic Surgeons 3
Intra-articular corticosteroid injections could be considered for symptomatic hip osteoarthritis (moderate recommendation), according to the American Academy of Orthopaedic Surgeons 3
For patients with progressive symptoms refractory to conservative measures, total hip arthroplasty may be indicated, as noted by the American Academy of Orthopaedic Surgeons 3
Acetaminophen may be considered when NSAIDs are contraindicated (consensus recommendation), according to the American Academy of Orthopaedic Surgeons 3

Patients with hip-related pain demonstrate lower muscle strength in hip adduction, abduction, flexion, internal rotation, and external rotation, according to the British Journal of Sports Medicine 8
Treatment should target hip muscle strengthening, particularly hip abductors, adductors, flexors, and rotators, as these demonstrate consistent weakness in patients with hip-related pain, as recommended by the British Journal of Sports Medicine 8
Functional performance tasks including single-leg balance and squat depth assessment should be incorporated into physical therapy protocols, as suggested by the British Journal of Sports Medicine 9

Plain radiographs are the first-line imaging modality for hip pain with internal rotation, including an AP view with 15 degrees of internal hip rotation and cross-table lateral view, as recommended by the American College of Radiology 10, 11, 12
Radiographs rapidly identify fractures, dislocations, and advanced arthritis, such as bone-on-bone articulation, subchondral sclerosis, and cystic changes, according to the American College of Radiology 10

The American College of Rheumatology suggests that poor correlation exists between radiographic severity and pain intensity in hip osteoarthritis, and patients with severe radiographic changes may have minimal symptoms and vice versa, according to the British Journal of Sports Medicine and Annals of the Rheumatic Diseases 13, 14
The British Journal of Sports Medicine recommends considering differential diagnosis, including lumbar spine pathology and femoroacetabular impingement (FAI) syndrome, which can present with similar pain patterns 15, 13
Annals of the Rheumatic Diseases guidelines indicate that imaging is not required for diagnosis when typical clinical features are present, such as characteristic pain pattern, age over 40, brief morning stiffness, and positive examination findings 14

The British Journal of Sports Medicine suggests that when imaging is indicated, anteroposterior pelvis and lateral femoral head-neck radiographs are the first-line studies 13

Patients with hip OA experience stiffness, brief morning stiffness or inactivity stiffness, and functional limitations, such as difficulty with activities like putting on shoes/socks, getting in/out of cars, and walking distances, as reported by the Annals of the Rheumatic Diseases 16
Patients with polyarticular hip OA are at increased risk for knee OA and generalized OA at other sites, according to the Annals of the Rheumatic Diseases 17
