Pilonidal sinus (PNS) is a clinically diagnosed condition caused by hair entrapment underneath the skin leading to a granulomatous reaction and the formation of a tract. PNS is commonly found in the sacrococcygeal area (natal cleft). However, this is a rare case presentation of a male patient with PNS located at the back of his neck region as there were only four similar conditions reported in the literature review. The patient was first managed medically as a case of hidradenitis suppurativa by the dermatology department. Later on, when the treatment failed, he was treated surgically as a case of PNS with an excellent outcome. The patient was seen at the outpatient clinic one week after surgery. The wound was healed completely and totally recovered.

Objectives: To characterize patients who underwent simultaneous bilateral total knee arthroplasty (simBTKA) and study the outcomes of surgery along with complication rates.
