Arthroscopic needle knife for knee video arthroscopic surgical portals

Abstract

Introduction: A new era of orthopedic surgery is happening nowadays. innovative procedures like video surgery; Ultrasound Guided Interventions; Pain interventionist orthopedics procedures; plastic surgery (cellulites subcision treatment); hydrodissection injections; dry needling; thermography assisted pain procedures and acupuncture started to be widely performed [3]. Objective: The aim of the research is to assess the possibility of a needle knife surgical device to perform portals of knee video arthroscopic surgical interventions and to evaluate the two diferentes needle-knife surgical devices [7-9]. Method: 200 consecutive knee Video Arthroscopies performed by the same team were divided in two groups: A and B. Group A: the lateral portal used a hypodermic needle 40X12 (18Gx 1’1/2) for portal performance. Group B submitted a lateral portal using a metal guide for intravenous catheter 14Gx2’’. The medial portal, a 11 blade knife, was used for both cases.Comparison of two groups by assessing wound healing time; superficial and deep infection; pain, cosmesis by a third person nurse.A surgeon’s opinion for friendly use comparing group A or B was made [8, 9]. Results: There were nor superficial or deep knee infections. No wound healing problems, same time of healing. No difference in pain related to the wound. Cosmesis were similar. The surgeon’s choice was the metal guide for intravenous catheter 14Gx2’’ is more friendly due to the rigidity in comparison to a hypodermic needle 40X12 (18Gx 1’1/2). Conclusion: The two needles seem suitable for knee video arthroscopy surgical interventions. The surgeon’s choice was the metal guide for intravenous catheter 14Gx2’’ is more friendly due to the rigidity in comparison to the 40x12 needle [7-9].
