Groin pain following hip arthroplasty has a spectrum of aetiologies. Although mild post-operative at six months to year is common, other causative factors should be considered where severe or persistent. The rectus femoris (RF) muscle the most common quadriceps tendons injured strained. Pathologies are known occur in athletic adults and children include tendinopathy, tear, avulsion, but RF rarely attributed post-arthroplasty. However, tendinopathy may as result altered biomechanics loading. We performed retrospective analysis 100 patients, our tertiary orthopedic hospital, who presented with chronic post arthroplasty. identified three patients straight (direct) head one patient calcific tendinopathy. Established causes septic/aseptic loosening, pseudotumor, iliopsoas bursitis/impingement, bursitis. In this report, we describe scanning technique, sonographic appearances, institutional experience post-arthroplasty pathologies which an underreported cause replacement. also recommend including routine US protocols hip.
