Refixation of labrum in pincer type of femoroacetabular impingement

We present the case of a single, retired, 51-year-old Taiwanese female who had left groin pain when squatting, sitting, and walking for months. She visited our outpatient department (OPD) for further evaluation. During physical examination at the OPD, limited hip flexion and abduction were observed in comparison with the contralateral hip in the supine position. Impingement tests including flexion, abduction, and external rotation test and flexion, adduction, and internal rotation test were positive. In addition, the extension external pain and Patrick test results were positive. Pelvis radiography revealed a crossover sign and lateral center-edge angle of 40.6°. Magnetic resonance imaging revealed a degenerative tear of the anterosuperior labrum with a prominent pincer lesion. Consequently, she was admitted for arthroscopy-assisted rim resection of the pincer-type lesion and labral refixation. After surgery, the patient recovered well.
