Knee joint injection is a procedure commonly performed for pain management of osteoarthritis. Although several techniques have been described, it is usually performed by either medial or lateral approach with the lower limb extended on the examination table. We present the case of a patient who developed saphenous neuropathy following knee joint injection via medial approach. The clinical picture suggests that the needle pierced the nerve during the procedure. The patient was moderately obese. This is the first case report in the literature of saphenous nerve injury following medial knee joint injection. Practitioners should be aware of this complication in choosing an approach to the knee joint injection, especially when the patient is obese and the anatomic landmarks are obscured.
膝关节注射是一种常用于骨关节炎疼痛管理的操作。尽管已经描述了几种技术，但通常是在检查台上下肢伸直的情况下通过内侧或外侧入路进行。我们报告一例经内侧入路膝关节注射后发生隐神经损伤的患者。临床表现提示在操作过程中针头刺破了神经。该患者为中度肥胖。这是文献中首例关于内侧膝关节注射后隐神经损伤的病例报告。从业者在选择膝关节注射入路时应意识到这种并发症，尤其是当患者肥胖且解剖标志不清时。
