Hip Surgery Expert Witness

Hip surgery cases can look similar on paper but involve very different standards of care. A fractured hip in an elderly patient raises different questions from a labral repair in a young athlete. A total hip replacement case may focus on component position or instability, while a trauma case may involve whether fixation was appropriate for the fracture pattern.

That distinction matters when selecting an expert. The strongest reviewer is usually an orthopedic surgeon whose current practice reflects the procedure and patient population at issue.

A broad orthopedic background may be sufficient for some cases. Others are better suited to an adult reconstruction specialist, orthopedic trauma surgeon, sports medicine surgeon, or another subspecialist with direct experience managing the condition being challenged.

Hip Fracture Surgery

Hip fractures frequently require operative treatment, particularly in older patients, but the appropriate procedure depends on the location and characteristics of the fracture.

Femoral neck fractures may be treated with internal fixation, hemiarthroplasty, or total hip replacement depending on factors such as displacement, age, function, bone quality, and the patient's overall health. Intertrochanteric and subtrochanteric fractures are generally approached differently and may require a cephalomedullary nail, plate, or other fixation.

In litigation, the expert may be asked whether the correct operation was selected, whether surgery occurred within an appropriate timeframe, and whether fixation or implant placement was technically acceptable.

The analysis should consider the fracture pattern and the patient's condition at the time of treatment rather than applying one preferred procedure to every hip fracture.

Total Hip Replacement

Total hip arthroplasty cases often involve questions about why the operation was performed, how the components were positioned, and what caused the patient's postoperative problem.

The expert may review whether the patient's arthritis, pain, functional limitation, and response to conservative treatment reasonably supported replacement. Once the procedure itself is challenged, issues can include acetabular cup position, femoral component position, leg length, offset, fixation, stability, and surrounding soft tissue.

Persistent pain after hip replacement has many possible causes. Loosening, infection, instability, fracture, tendon irritation, nerve injury, referred spinal pain, and other conditions may all need to be considered.

A poor outcome is not enough to establish improper technique. The expert should identify a medically supported explanation for the result and determine whether it is attributable to the surgery.

Hip Arthroscopy

Hip arthroscopy is commonly used to treat conditions such as femoroacetabular impingement, labral tears, and selected cartilage pathology.

These cases can involve disputes over patient selection, interpretation of imaging, the extent of bone resection, labral repair, postoperative instability, persistent impingement, or progression of underlying arthritis.

One recurring issue is whether arthroscopy was likely to benefit a patient who already had substantial degenerative joint disease. The presence of a labral tear does not necessarily mean it was the primary source of symptoms or that arthroscopic treatment was appropriate.

For cases centered on hip preservation procedures, an orthopedic surgeon with significant hip arthroscopy experience may be a stronger fit than a surgeon whose practice is primarily joint replacement. For how qualification attaches to the specific opinion, see qualifying an expert witness.

Dislocation and Instability

Dislocation is a recognized complication after total hip replacement, but repeated instability can raise questions about component position, soft tissue tension, surgical approach, patient factors, or postoperative events.

An expert may evaluate when the dislocation occurred, what activity preceded it, how the components appear on imaging, whether there was evidence of impingement, and whether revision should have been considered after recurrent events.

Not every postoperative dislocation reflects negligent surgery. Some occur despite acceptable component position and appropriate care.

The analysis becomes stronger when the expert can explain the likely mechanism of instability and connect it to objective findings in the record.

Leg Length Discrepancy

Perceived or actual leg length difference is another issue that appears in hip replacement litigation.

Small differences can occur after surgery and may be clinically acceptable, especially when length is adjusted to improve stability. Larger discrepancies can affect gait, comfort, and function and may require shoe modification or additional treatment.

The expert may need to distinguish true bony leg length discrepancy from apparent discrepancy caused by pelvic tilt, contracture, spinal deformity, or other factors.

Preoperative measurements and imaging are important because some patients have a preexisting difference before the replacement is performed.

Periprosthetic Fracture

A fracture around a hip implant can occur during the original operation, in the postoperative period, or years later after trauma.

The expert may be asked whether an intraoperative fracture should have been recognized, whether it was treated appropriately, and whether the implant remained stable. Later fractures may require analysis of bone quality, implant fixation, trauma, and the location of the fracture relative to the prosthesis.

Treatment decisions can range from fixation to revision arthroplasty depending on the fracture pattern and implant stability.

Adult reconstruction and orthopedic trauma expertise can both become relevant in complex periprosthetic fracture cases.

Infection After Hip Surgery

Deep infection after hip surgery can lead to repeated operations and substantial long-term morbidity.

In joint replacement cases, the dispute may involve whether infection was recognized, whether aspiration or laboratory testing was obtained, whether antibiotics were managed appropriately, and whether implant retention or removal was the correct approach.

The timing of infection matters. An acute postoperative infection may be treated differently from a chronic periprosthetic joint infection that develops or becomes apparent later.

The orthopedic expert typically addresses the surgical management. An infectious disease expert may also be necessary when the case turns on antimicrobial therapy, organism identification, or duration of treatment. For when that split is necessary, see when your case needs two expert witnesses.

Nerve Injury

Several nerves can be affected during hip surgery, including the sciatic and femoral nerves.

Postoperative weakness, numbness, foot drop, or neuropathic pain may raise questions about traction, limb positioning, retractor placement, hematoma, component position, or another mechanism.

Some nerve injuries are recognized complications even when the surgery is performed properly. The expert must determine whether the timing and pattern of the deficit support a particular cause.

Neurology or electrodiagnostic expertise may be helpful when the extent and location of the nerve injury are disputed.

Vascular Complications

Major vascular injury during hip surgery is uncommon but potentially severe.

Litigation may involve bleeding, arterial damage, thrombosis, hematoma, or delayed recognition of impaired circulation. The relationship between the surgical field and nearby vessels can become particularly relevant in revision procedures or cases involving displaced hardware.

An orthopedic expert may address whether the surgical approach and response were appropriate, while vascular surgery may be needed to evaluate the vascular injury and treatment itself.

Revision Hip Surgery

Revision hip surgery is generally more complex than a primary replacement because the anatomy has been altered and bone loss, scar tissue, infection, instability, or implant failure may already be present.

A patient may require revision for loosening, recurrent dislocation, fracture, infection, wear, component malposition, or another mechanical problem.

The reason for revision should be identified before drawing conclusions about the original operation. The fact that a replacement was revised does not establish that it was negligently performed.

In cases involving complex reconstruction, an orthopedic surgeon who regularly performs revision total hip arthroplasty is usually better positioned to address the standard of care.

Avascular Necrosis and Hip Preservation

Some hip surgery cases involve avascular necrosis, also called osteonecrosis, where loss of blood supply damages the femoral head.

Treatment can range from observation and joint-preserving procedures to total hip replacement depending on disease stage, symptoms, age, and the amount of structural collapse.

An expert may be asked whether the condition was diagnosed promptly, whether a joint-preserving procedure remained reasonable, or whether replacement had become the more appropriate option.

These cases require attention to disease progression because the treatment available at an early stage may no longer be effective once significant collapse has occurred.

Causation After Hip Surgery

Hip surgery patients often have substantial preexisting disease before the procedure.

Arthritis, osteoporosis, prior fractures, congenital deformity, spinal disease, previous operations, obesity, and other conditions can influence both the need for surgery and the eventual outcome.

The expert should determine the patient's baseline condition and then identify what objectively changed after the procedure. New pain does not always indicate a new structural injury, and persistent symptoms may reflect pathology that existed before surgery.

A defensible causation opinion connects the operative event to the claimed impairment through the medical record, imaging, examination findings, and clinical course.

Records Reviewed in Hip Surgery Litigation

Hip cases often depend heavily on imaging before and after surgery.

Preoperative radiographs, CT studies, MRI, clinic notes, and prior treatment records establish the underlying condition. The operative report provides information about the procedure, surgical approach, implants, fixation, and any complications noted at the time.

Postoperative radiographs may help evaluate component position, fracture, dislocation, loosening, or changes over time. Therapy notes can show gait, strength, range of motion, and functional recovery. Radiology may be needed when imaging interpretation itself is disputed.

When revision surgery occurs, the revision operative report can be particularly valuable because it may document findings that clarify why the original procedure failed. Related orthopedic issues are also covered in our orthopedic surgery expert witness overview.

Choosing the Right Hip Surgery Expert

The procedure should determine the specialty match.

An adult reconstruction surgeon is generally the strongest fit for total hip replacement, implant failure, and revision arthroplasty. An orthopedic trauma surgeon may be more appropriate for complex fractures. A hip preservation or sports medicine specialist may be needed for arthroscopy and labral surgery.

The goal is not simply to find an orthopedic surgeon. It is to find one whose current clinical practice includes the same type of surgery, complication, and decision being evaluated. Start an expert witness search when you are ready to retain.
