Objective: This report outlines the use of extracorporeal shockwave therapy (ESWT) for treatment of calcium pyrophosphate deposition disease (CPPD) in a 59-year-old male’s knees.
Clinical Features: A 59-year-old man had bilateral knee pain. After examination and radiographs, he was diagnosed with bilateral CPPD. He was treated with low-level laser, interferential therapy, and therapeutic ultrasound with minimal improvement. After we found literature suggesting ESWT as a potential option, he was approached about a course of ESWT.
Intervention/Outcome: He received an 8-week treatment of ESWT to his knees. The primary endpoint was pain reduction. After completing treatment, he had decreased pain as well as increased range of motion bilaterally. He also experienced improvements in functional ability as seen in his higher Lower Extremity Functional Scale (LEFS) scores.
Conclusion: ESWT may represent a promising adjunctive therapy for CPPD. Optimal treatment duration may vary depending on disease severity and chronicity. Further research is necessary for optimal ESWT treatment plans, to explore post-ESWT treatment, and understand short- and long-term effects of ESWT on CPPD.
