Hip arthroscopy is a minimally invasive, effective and innovative orthopedic procedure with a relatively low rate of complications. In our patient, residual cam deformity and a bone fragment that remained in the front hip capsule after hip arthroscopy performed three years before caused thigh numbness, muscle fasciculations, and paresthesia. It was assumed that the loose bony fragment remained following burring on prior procedure. During hip flexion, neural structures were compressed and caused the mentioned symptoms. Revision hip arthroscopy was performed and the loose fragment in addition to residual cam deformity was removed. Resolution of pain and anterior thigh numbness was reported after the revision surgery. Key words: Hip arthroscopy; Arthroscopy; Cam lesion; Loose fragment; Tigh numbness; Muscle fasciculations; Paresthesia Artroskopija kuka je minimalno invazivni, ucinkovit i inovativni ortopedski zahvat s niskim rizikom od komplikacija. Kod naseg bolesnika ostatna cam lezija i fragment kosti koji je zaostao u prednjem dijelu cahure kuka nakon artroskopije kuka izvedene tri godine ranije izazvao je utrnulost natkoljenice, fascikulacije misica i parestezije. Pretpostavljamo da je kostani ulomak zaostao kao komplikacija brusenja kosti u prethodnom zahvatu. Prilikom feksije kuka komprimirao je zivcane strukture i posljedicno izazivao spomenute simptome. Komplikacija je rijesena revizijskom artroskopijom kuka i uklanjanjem slobodnog fragmenta. Nakon revizijske operacije doslo je do smanjenja boli i prestanka utrnulosti prednjeg dijela bedra u naseg bolesnika. Kljucne rijeci: Artroskopija kuka; Artroskopija; Lezija cam; Slobodni fragment; Utrnulost bedra; Fascikulacije misica; Parestezije
