Hip osteoarthritis is a progressive, disabling condition that limits walking, standing, and virtually every aspect of daily mobility. For veterans, it often develops earlier and more severely than in age-matched civilians, and military service is frequently a significant contributing cause. Understanding that pathway is the foundation of a successful VA claim.
The hip is a ball-and-socket joint where the head of the femur (thigh bone) articulates with the acetabulum (pelvis socket). Articular cartilage covers both surfaces, enabling smooth, low-friction movement. Osteoarthritis occurs when that cartilage breaks down, leaving bone to contact bone, causing pain, stiffness, and loss of range of motion.
On imaging, hip OA appears as:
Symptoms typically include groin pain, pain with walking and weight-bearing, stiffness after rest, decreased internal rotation, and a shortened stride.
The hip joint transmits three to five times body weight during normal walking. Add a rucksack with 50 to 80 pounds, multiply that across years of daily training, land navigation, forced marches, and operational deployments, and the cumulative loading on the hip cartilage is enormous.
Cartilage has limited capacity to regenerate. When loading rates exceed the tissue's repair capacity over a sustained period, the degenerative process accelerates. Veterans in infantry, airborne, and other high-demand occupational specialties often develop hip OA a decade or more earlier than their civilian counterparts.
Hip injuries during service, including acetabular fractures, femoral neck stress fractures, hip labral tears, and significant contusions, alter joint mechanics and initiate a degenerative cascade. Post-traumatic arthritis after a documented in-service hip injury is one of the strongest service-connection pathways available.
Service-connected knee or ankle conditions frequently produce compensatory gait changes that overload the hip on the ipsilateral or contralateral side. A veteran who walks with a limp to protect a service-connected knee puts abnormal stress on the hip, accelerating OA through a secondary mechanism. See our article on bilateral joint conditions and the VA bilateral factor for how this affects rating.
Osteoarthritis confirmed by X-ray is rated under DC 5003. Under this code, the rating depends on the number of affected major joints and whether incapacitating episodes occur:
If range of motion is limited, the hip is rated under the specific limitation of motion codes for that joint. The primary hip motion codes are DC 5251 (limitation of extension of the thigh) and DC 5252 (limitation of flexion of the thigh). Additional codes cover abduction (DC 5253) and rotation (DC 5254). The painful motion rule under 38 CFR 4.59 requires documentation of pain throughout the motion arc, not just the maximum angle.
As with knee conditions, the VA must apply whichever rating is higher: DC 5003 or the applicable motion code.
Total hip arthroplasty is rated under DC 5054. The rating structure mirrors that of total knee replacement under DC 5055 and includes a mandatory post-surgical rating period that veterans must not miss:
If you underwent total hip replacement for a service-connected or potentially service-connected hip condition and did not receive a 100% rating for the year following surgery, you may be owed back pay. File immediately after surgery to lock in the effective date.
Hip OA claims need the same three-element foundation as other musculoskeletal claims: in-service event or exposure, current diagnosis, and a medical nexus opinion.
The nexus opinion for hip OA often needs to explain the cumulative loading mechanism in more detail than for knee conditions, because reviewers are sometimes less familiar with the hip's loading dynamics. A strong nexus letter will:

Hip OA is frequently rateable as a secondary condition to:
Each secondary pathway requires its own nexus opinion, but secondary claims can be significantly more straightforward to establish than direct service connection.
