Psoas capsuloraphy

The psoas capsuloraphy is an operation done in patients who continue to have groin pain after total hip replacement.

In persistent groin pain after total hip replacement, the underlying cause may be mechanical. This pain is usually present immediately after surgery. These patients cannot raise their leg because of too much groin pain.

The mechanical cause lies in the contact between the pommel of the prosthesis and the psoas (muscle in the groin). The rubbing of the muscle against the cup causes this muscle to inflame.

When exercise therapy and infiltrations have insufficient effect, a psoas capsuloraphy can be done. This involves partially loosening the joint capsule and placing it between the prosthetic cup and the psoas. The mechanical cause is then resolved.

This way, there is no need to surgically release the psoas (psoas release), and the muscle is preserved.
