Rationale

Pes anserine (PA) bursitis is an inflammatory condition of the medial knee. The PA bursa becomes more painful when infected, damaged, or irritated. Although various treatment options have been attempted to treat PA bursitis, optimal treatments are still debated. This study aims to investigate the effect of polydeoxyribonucleotide (PDRN) injection on reducing pain and inflammation in a patient presenting with PA bursitis.

Patient concerns

A 50-year-old female patient was admitted to our pain clinic with symptoms of tenderness and pain over the medial knee. Physical examination revealed the pain to be located over the proximal medial tibia at the insertion of the conjoined tendons of the PA. The knee had lost its range of movement and strength, and resisted knee flexion.

Diagnoses

She was diagnosed as having PA bursitis.

Interventions

Ultrasound guided PA bursa injection was carried out.

Outcomes

Follow-up for the patient was more than eight months. She showed good improvement in PA bursitis without any complications.

Lessons

This is the first successful report of successful PDRN injection for PA bursa.

Abbreviations

ESWT = extracorporeal shock wave therapy, NRS = Numeric Rating Scale, NSAIDs = nonsteroidal anti-inflammatory drugs, PA = pes anserine, PDRN = polydeoxyribonucleotide.

理论基础

麻痹性滑囊炎(PA)是膝关节内侧的一种炎症状态。当受到感染、损坏或刺激时，PA法氏囊会变得更加疼痛。虽然已经尝试了各种治疗方案来治疗PA滑囊炎，但最佳治疗方案仍然存在争议。本研究旨在观察多聚脱氧核糖核苷酸(PDRN)注射液对1例PA滑囊炎患者的止痛和消炎作用。

患者关注

一名50岁的女性患者在我们的疼痛诊所住院，症状为膝关节内侧压痛。体格检查显示疼痛位于胫骨内侧近端，位于PA的连合肌腱的附着处。膝盖失去了活动范围和力量，并抵抗了膝盖的屈曲。

诊断

她被诊断为PA滑囊炎。

干预

超声引导下PA法氏囊注射。

结果

患者的随访时间超过8个月。她的PA滑囊炎有很好的改善，没有任何并发症。

经验教训

这是第一例成功注射PDRN治疗PA法氏囊的报告。

缩写

ESWT=体外冲击波治疗，NRS=数字评分，NSAIDs=非甾体抗炎药，PA=PES anserine，PDRN=多脱氧核苷酸。
