One-stage bilateral short-stem total hip arthroplasty

One-stage bilateral short-stem total hip arthroplasty is a strategic approach that combines the advantages of short-stem implants with the efficiency of simultaneous bilateral hip replacement. It aims to provide comprehensive and streamlined care for patients with bilateral hip joint pathology, promoting faster recovery and improved functional outcomes.

Over the last decade one-stage bilateral short-stem THA has increasingly been used due to the advantages of short stems compared to conventional stem designs. 

Thus, there is huge experience today and for most patients that are bilaterally affected, it is in many ways beneficial. 

One-stage bilateral short-stem THA offers multiple benefits

One-stage bilateral short-stem total hip arthroplasty (THA) involves performing hip replacement surgery on both hips during a single surgical session. This approach offers several advantages, including:


Simultaneous Correction of Bilateral Hip Pathology

One of the primary benefits of one-stage bilateral short-stem THA is the simultaneous correction of hip pathology in both hips. Patients with bilateral hip joint issues, such as osteoarthritis or other degenerative conditions, can undergo comprehensive treatment in a single surgical setting.

Reduced Overall Surgical Burden

Performing bilateral hip arthroplasty in a single session minimizes the overall surgical burden on the patient. This approach reduces the need for two separate surgeries with their associated pre-operative preparations, recovery periods, and rehabilitation phases.

Faster Rehabilitation and Recovery

Patients undergoing one-stage bilateral short-stem THA may experience faster rehabilitation and overall recovery. Since both hips are addressed simultaneously, rehabilitation efforts can focus on restoring function to both joints concurrently, potentially leading to a quicker return to daily activities.


From a healthcare system perspective, one-stage bilateral short-stem THA can be cost-effective compared to staging the surgeries. It reduces hospitalization costs, anesthesia expenses, and overall healthcare resource utilization associated with two separate surgeries.

Single Anesthetic Episode

Performing bilateral hip replacements in one session means that the patient undergoes a single anesthetic episode. This can be advantageous, especially for individuals with comorbidities or concerns related to anesthesia, as it minimizes the exposure to anesthesia-related risks.

Convenience for the Patient

For patients with bilateral hip joint issues, undergoing a one-stage procedure offers the convenience of addressing both hips at once. This can be particularly beneficial for individuals who may have logistical challenges, such as transportation or caregiving arrangements, for multiple hospital visits.

Symmetrical Rehabilitation

With one-stage bilateral short-stem THA, the rehabilitation process is symmetrical for both hips. Physical therapy and exercises can be tailored to address the needs of both joints simultaneously, potentially leading to better balance and coordination during the recovery period.

Early Restoration of Function

Simultaneously addressing both hips allows for the early restoration of function in both joints. Patients may experience improved mobility and reduced pain in both hips, enhancing their overall quality of life sooner after surgery.

While one-stage bilateral short-stem THA offers numerous advantages, it is important to consider patient factors, surgeon expertise, and potential risks. Patient selection, thorough preoperative assessment, and careful surgical planning are essential to ensure optimal outcomes and minimize complications. Additionally, individual patient preferences and medical conditions should be taken into account when determining the appropriateness of this approach.
