Abstract

Purpose: This study aims to measure the peri-incisional numbness developing after Total Knee Arthroplasty (TKA) performed using the midline skin incision. It studies the natural course of the numbness and determines its correlation with the skin incision length (SIL).

Materials & methods: 66 knees undergoing primary TKA with a standard midline incision were evaluated. The SIL and the area of numbness (AON) were measured in complete knee extension and 90° of flexion. The area was marked by the patient using a sketch pen and then determined by an independent observer using monofilament testing. The "ImageJ" software was used to calculate the area.

Results: All patients developed numbness around the knee after TKA. There was a statistically significant correlation between the SIL and AON in both flexion and extension at two weeks (p < 0.001) and three months (p < 0.001). However, there was a weak and insignificant correlation at six months (p = 0.217).

Conclusion: When TKA is performed using the midline skin incision, the SIL positively correlates with the AON postoperatively during the initial short-term follow-up. At six monthly follow-ups, there is no significant correlation between the two.

全膝关节置换术后麻醉不足的客观测量及其与皮肤切口长度的相关性：一项前瞻性研究。

目的：本研究旨在测量使用中线皮肤切口进行全膝关节置换术（TKA）后出现的切口周围麻木感。材料和方法：对 66 个采用标准中线切口进行全膝关节置换术（TKA）的膝关节进行了评估。在膝关节完全伸直和屈曲 90° 时测量 SIL 和麻木区域 (AON)。该区域由患者用勾画笔标记，然后由独立观察者使用单丝测试进行测定。使用 "ImageJ "软件计算面积：结果：所有患者在 TKA 术后均出现膝关节周围麻木。结果：所有患者在 TKA 术后都出现了膝关节周围麻木的症状：使用中线皮肤切口进行 TKA 手术时，在最初的短期随访中，SIL 与术后 AON 呈正相关。在六个月的随访中，两者之间没有明显的相关性。

期刊介绍： International Orthopaedics, the Official Journal of the Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT) , publishes original papers from all over the world. The articles deal with clinical orthopaedic surgery or basic research directly connected with orthopaedic surgery. International Orthopaedics will also link all the members of SICOT by means of an insert that will be concerned with SICOT matters. Finally, it is expected that news and information regarding all aspects of orthopaedic surgery, including meetings, panels, instructional courses, etc. will be brought to the attention of the readers. Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted. Reports of animal experiments must state that the "Principles of laboratory animal care" (NIH publication No. 85-23, revised 1985) were followed, as well as specific national laws (e.g. the current version of the German Law on the Protection of Animals) where applicable. The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfil the above-mentioned requirements.
