Introduction: Hydroxyapatite deposition disease (HADD) is defined by calcium hydroxyapatite crystal accumulation in periarticular soft tissues, most commonly affecting the rotator cuff.¹ Knee involvement is rare, making such cases diagnostically challenging.¹ While standard therapies include conservative management, corticosteroids, shock wave therapy, and surgery, ultrasound-guided aspiration and lavage have shown promise as minimally invasive options.² These techniques are well-described in shoulder HADD but remain less studied in atypical sites like the knee.³
