Persistent groin pain after hip replacement

Ross Hauser, MD and Danielle Matias, PA-C

People will send us emails that go something like this:

Often we will hear from people that they have leg, or hip, or back pain following hip replacement. Sometimes they will tell us about groin pain that has restricted their ability top return to sport or work. Sometimes they will tell us that their pain is a “mystery” to their doctors. For more on this subject, please see our article: What causes long-term hip pain after hip replacement?

In this article we will focus more on the issue of groin pain following hip replacement.

Part 1: What can cause groin pain after hip replacement?

In this section we will go over some of the causes of groin pain after hip replacement and cite the opinions of doctors and researchers in addressing this problem.

Is it the size of the implant? Possibly, but that may not be all.

In December 2020, doctors at the Department of Orthopaedic Surgery, David Geffen School of Medicine at UCLA, the University of Toronto and the Adult Reconstruction and Joint Replacement Division, at the Hospital for Special Surgery in New York combined to assess the causes of chronic groin pain after hip replacement with a focus on possibly the oversized femoral implant head size characteristic of implants used in dual mobility  total hip replacement. (1) Dual mobility hip replacement adds an addition polyethylene component which is seen as superior in younger patients who are more active and this type of device reduces or even eliminates the risk of dislocation of the implant. What this research study found was that “Overall, 8.7% of hip replacement patients reported groin pain at one year. Patients with groin pain were younger and had lower body mass index (BMI)” Suggesting a more active patient. They also added the dual mobility hip replacement did not put the patient at any more greater risk for groin pain. The researchers note: “In this (study’s) population of hip arthroplasty patients, the incidence of groin pain one year after surgery did not differ among patients undergoing dual mobility and conventional hip replacement; dual mobility hip replacement in particular was not associated with a higher risk of groin pain, despite its comparatively larger femoral head sizes. Traditional hip replacement, on the other hand, was associated with a higher risk of pain.”

Impingement of the iliopsoas tendon

In an April 2017 paper, doctors at the Mayo Clinic writing in the Journal of bone and joint surgery (2) suggest that a potential cause of persistent groin pain after total hip arthroplasty is impingement of the iliopsoas tendon. Treatment options include conservative management, tenotomy, and acetabular revision (surgery to adjust or replace the hip socket component).

In looking to suggest treatment options the Mayo doctors looked at 49 patients with a diagnosis of iliopsoas impingement after primary total hip arthroplasty

At the most recent follow-up, 10 patients (50%) in the nonoperative group had groin pain resolution compared with 22 patients (76%) in the operative group.

Nonoperative management of iliopsoas impingement led to groin pain resolution in 50% of patients. In patients with minimal acetabular component prominence, iliopsoas release provided a high rate of success.

A March 2023 paper in The Journal of arthroplasty (3) “found an incidence of 2.2% of iliopsoas tendinopathy patients after anterior (front) approach total hip replacement that compromised outcomes. Younger age and previous spine fusion were identified as most important risk factors. These patients were 5 times more likely to report low back pain and greater trochanter pain post-total hip replacement.”

Part 2: Treatments for groin pain after hip replacement

In tenotomy revision surgery the answer to iliopsoas impingement generated pain after hip replacement?

A September 2021 editorial by Dr. Andrew Blackman published in the Journal of arthroscopic and related surgery (4) discusses the challenges of diagnosing and treating Iliopsoas tendon pain following hip replacement.

“Iliopsoas tendon pain can be a frustrating condition for both patients and surgeons after total hip arthroplasty. It is difficult to diagnose definitively, as there is no imaging modality that offers reliable information and there are numerous causes of persistent groin pain in this patient population. The pain can ruin the results of an otherwise well-functioning total hip arthroplasty.”

Dr. Blackman continues on who would best benefit and least benefit from iliopsoas tenotomy.

“Patients who respond best to arthroscopic iliopsoas tenotomy are those with isolated pain with hip flexion activities and reproducible pain with resisted hip flexion (typically a band that provides resistance against bending your knee upwards towards your head) on examination or other provocative iliopsoas maneuvers.

Patients with these symptoms in addition to more generalized pain findings (pain with weight-bearing, pain at night, pain with passive range of motion) tend not to respond as favorably to isolated iliopsoas tenotomy.”

Success of Endoscopic Iliopsoas Tenotomy for Treatment of Iliopsoas Impingement After Total Hip Arthroplasty

A July 2019 paper in The Journal of arthroplasty (5) wrote: “Iliopsoas impingement after total hip arthroplasty (replacement) occurs in up to 4.3% of patients resulting in functional groin pain. Operative treatment historically has included open iliopsoas tenotomy or acetabulum revision.” In this paper the researchers wanted to demonstrate effectiveness and risks in patients treated with endoscopic iliopsoas tenotomy for iliopsoas impingement after total hip replacement.


In February 2021 doctors writing in the journal Cureus (6) wrote that “Controversy exists over the risks and benefits of tenotomy versus revision as a surgical solution.” In this paper the doctors reported on their “limited experience with combined acetabular revision (replacing the cup component of the hip replacement) and partial iliopsoas tenotomy when other conservative treatments have failed.”

The doctors assessed eight patients diagnosed with iliopsoas impingement following hip replacement. All patients had prolonged groin pain for an average of two years and had failed conservative treatment for at least six months.

All patients underwent acetabular revision with partial psoas tendon release.

Cortisone for iliopsoas tendonitis

A December 2022 from Rush University Medical Center, published in The Journal of arthroplasty (7) evaluated the effectiveness of ultrasound-guided corticosteroid injections for iliopsoas tendonitis following total hip replacement. In this study, 42 patients who received an ultrasound-guided corticosteroid injection for iliopsoas tendonitis after primary hip replacement were assessed at one year follow up for need for another surgery, groin pain at last follow-up, the need for additional intra-bursal injection and pain and function scores. Further, scans were taken to determine hardware failure or mispositioning (anterior cup overhang) as a cause of  iliopsoas tendonitis.

Among the 22 patients who did not have anterior cup overhang, four (18.2%) had persistent groin pain at average follow-up of 40 months after ultrasound-guided corticosteroid injections. Three patients had a second injection, none had groin pain at most recent follow-up. No patients required acetabular revision. Resolution of groin pain was demonstrated in 78.6% of patients in the group; however, those who did not have acetabular overhang had higher rates of success. The overall revision surgery rate was 11.9%. The study concludes: “Ultrasound-guided corticosteroid injections appears to be safe and effective in the diagnosis and treatment of iliopsoas tendonitis following primary total hip replacement.”

Persistent groin pain following total hip replacement treated with physical therapy

A March 2022 paper in the journal Physiotherapy theory and practice (5) wrote that hip impingement syndrome can occur after total hip replacement and that nonoperative treatment is inconsistently recommended and surgical options include iliopsoas tenotomy. In this case, a patient with persistent groin pain after total hip replacement and iliopsoas tenotomy is presented:

Prolotherapy for groin related pain after hip replacement

Prolotherapy is a regenerative treatment that can successfully treat groin pain after hip replacement by way of repairing the ligaments and tendons stretched or cut during the hip replacement procedure. Prolotherapy injections to the sacrotuberous ligaments and the hamstring tendon attachment will stimulate the repair of these damaged areas. A comprehensive exam by the experienced Prolotherapist is vital for a thorough treatment. Sometimes pain in other areas is also involved. For instance, pain in the ischial tuberosities may be coupled with pain in the pubic symphysis. There may also be a pain in the sacroiliac joints.
