Psoas Interposition Capsuloplasty: Addressing Groin Pain After Hip Arthroplasty

After a total hip arthroplasty, some patients may experience persistent groin pain. This can be caused by mechanical contact between the iliopsoas (hip flexor) muscle and the prosthetic cup. Previously, this would necessitate a revision of the cup. We now use a technique where the joint capsule is partially released and repositioned between the iliopsoas and the prosthetic cup. This eliminates mechanical friction, allowing the hip flexor to glide over the cup without issue.

The aim of this surgery is to reduce persistent groin pain after a total hip arthroplasty, without the need for prosthetic revision.

• You will be given local anaesthesia with a spinal block and sedation.
• The surgeon will make an incision at the front of the hip.
• The muscles will be retracted, not cut.
• The capsule will be partially released, repositioned between the iliopsoas and the prosthetic cup, and sutured into the pelvic bone. The wound will then be closed with dissolvable sutures and surgical glue.
• You will stay in hospital for one to two nights.

Our HipCloud application guides and monitors the pre- and post-operative journey.

• For the first four weeks, the capsule needs to heal in place. You will walk with crutches but are allowed full weight-bearing. You must not fully extend the hip. Therefore, you will use a flexion brace during this period.
• After four weeks, you will have a follow-up appointment. Rehabilitation can then begin.
• You can gradually resume daily activities.
• Full rehabilitation can take 3 to 6 months.

At the European Hip Center, we combine advanced surgical techniques with personalised care. HipCloud, our digital platform, plays a crucial role in this:

• Before surgery: preparation with education and guidance.
• After surgery: monitoring your recovery and supporting rehabilitation.

This approach ensures a faster and safer recovery, tailored to your personal situation.
