In the sensory examination performed 20 min later, sensory loss was noted in the LFCN, genitofemoral, anterior femoral cutaneous, obturator, and saphenous nerves. [...]patient reported significant quadriceps weakness with the inability to achieve a straight leg raise. The advantages of PENG block to LPB are as follows: it can be applied in the supine position; injection point is far from neurovascular tissues; it is relatively safer for patients using anticoagulants; and bilateral block probability is nearly zero. [...]although quadriceps weakness has been previously reported after PENG block [2], its probability is delivered at high volumes as in our case 1. [...]although it is not yet possible, in the future, cadaveric, radiologic, and randomized controlled studies will provide answers to the following questions: can PENG block be an alternative to lumbar plexus block?
