Lateral and medial epicondylitis are relatively common diseases, but they do not improve quickly and are known to reduce patients' quality of life. Much research has been done on Platelet-Rich Plasma (PRP) as a treatment for lateral epicondylitis, but research on medial epicondylitis is lacking. The purpose of this study is to compare: (i) the pain intensity; and (ii) the functional outcome between the simultaneous treatment of medial and lateral epicondylitis and the treatment of only lateral or medial epicondylitis using PRP.
In this retrospective study, 209 patients treated with PRP on epicondylitis between March 2018 and December 2021 were enrolled. Simultaneous treatment was underwent 68 patients (group I). Seventy patients were treated for lateral epicondylitis (group II). The remaining 71 patients were treated for medial epicondylitis (group III). The visual analogue scale for pain (VAS) and the Mayo elbow performance score (MEPS) were evaluated for clinical outcomes at the initial visit and 6 months after injection.
VAS for pain and MEPS showed significant improvement in all three groups compared to before treatment. There was no significant difference between three groups on -ΔVAS (P > 0.05). However, in case of ΔMEPS, group III showed significantly lower compared to groups II and III (P < 0.05). No patients showed worsening of symptoms or complications during the treatment.
PRP injection for the patient with elbow medial and lateral epicondylitis can be treated effectively simultaneously in terms of pain. From a functional point of view, the effect of simultaneous treatment may be lessened than in the case of only lateral and medial treatment.
肱骨外上髁炎和内上髁炎较为常见，但治疗效果不佳，且已知会降低患者的生活质量。已有大量研究探讨富血小板血浆（PRP）治疗肱骨外上髁炎，但针对内上髁炎的研究则较少。本研究旨在比较：（i）疼痛强度；（ii）PRP 治疗同时治疗内上髁炎和外上髁炎与仅治疗外上髁炎或内上髁炎的功能结果。
在这项回顾性研究中，纳入了 209 名在 2018 年 3 月至 2021 年 12 月期间接受 PRP 治疗的肱骨外上髁炎和内上髁炎患者。68 名患者接受同时治疗（I 组）。70 名患者接受外上髁炎治疗（II 组）。其余 71 名患者接受内上髁炎治疗（III 组）。在初始就诊和注射后 6 个月时，使用视觉模拟量表（VAS）评估疼痛和 Mayo 肘部表现评分（MEPS）评估临床结果。
三组患者的 VAS 疼痛评分和 MEPS 评分与治疗前相比均有显著改善。三组之间 -ΔVAS 无显著差异（P>0.05）。然而，在ΔMEPS 方面，III 组与 II 组和 III 组相比，明显较低（P<0.05）。在治疗过程中，无患者出现症状恶化或并发症。
PRP 注射治疗肘部内外上髁炎在疼痛方面可以同时有效治疗。从功能角度来看，同时治疗的效果可能不如仅治疗外上髁炎或内上髁炎的效果。
