The problems of persistent groin pain after Total Hip Arthroplasties (replacement) is a growing concern.  Doctors in Germany revealed troubling complication rates: (1)

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.

Is it iliopsoas impingement?

In February 2021 doctors writing in the journal Cureus (3) wrote that “persistent groin pain after total hip arthroplasty can result from iliopsoas impingement on the acetabular rim. 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 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. No stems (hardware) were revised. Dislocations, complications, and clinical outcomes are reported in this study.

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

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. (4) 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 stuyd 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).

Conclusion: In this 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. ”
