不少病人即使用了止痛药和软骨保护剂,其疼痛症状也只是稍有减轻,病人还是无法自如地行走。既然口服药物对关节局部的治疗效果不好,这种情况下,直接给关节用药——关节腔内注射似乎是理所当然的选择。关节腔内注射,由于药物是直接作用在疼痛明显的地方,因此理论上来说,效果应该会更理想。 Many patients even use painkillers and cartilage protective agent, the pain symptoms are only slightly reduced, the patient still can not walk freely. Since orally administered drugs do not work well for the local treatment of the joints, direct administration of the joint to the joint in such a case seems to be a natural choice for intra-articular injection. Intra-articular injection, because the drug is a direct effect of pain in the place, so in theory, the effect should be more satisfactory.
