Dermal hypoesthesia surrounding the incision after total knee arthroplasty: how to treat? / 中国组织工程研究

ABSTRACT

BACKGROUND: Dermal hypoesthesia surrounding the incision usually occurs after total knee arthroplasty (TKA), which severely affects the patients' life quality. But the relevant studies are still immature, and its prevention methods and prognosis remain controversial.OBJECTIVE: To review the research and progress of dermal hypoesthesia following TKA.METHODS: A computer-based online research of CJFD, WanFang, VIP and Medline databases was performed for the literature addressing the dermal hypoesthesia surrounding the incision after TKA published from December 2001 to December 2016. The keywords were "total knee arthroplasty, incision, numbness, abnormal sensation" in English and Chinese, respectively. Finally, 36 eligible articles were selected for result analysis after excluding the repetitive ones.RESULTS AND CONCLUSION: (1) Dermal hypoesthesia surrounding the incision following TKA is commonly seen, but the related researches are few. Most of researches concentration on protecting against cutaneous nerve injury by modifying surgical approach, nerve conduit, neural nutrients and surgical repair, but all possess certain shortcomings, so there is a lack ideal prevention scheme. (2) The repairing methods for peripheral nerve injury, including biomolecular, cell and catheter therapies, have been applied in the repair of cutaneous nerve injury following TKA, but still on initial stage,and its effectiveness and safety need to be confirmed in depth. (3) Therefore, whether dermal hypoesthesia surrounding the incision following TKA needs treatment or not, and how to treat is an urgent problem for joint surgeon.
