It most commonly affects the knee, followed in frequency by the elbow, ankle, hip, and shoulder. Although SC usually presents as a monoarticular condition, bilateral, extra-articular, or multifocal involvement is uncommon.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>We report a 78-year-old patient with a history of cerebrovascular event and coronary artery disease who presented with bilateral intra-articular synovial chondromatosis extending extra-articularly to the right popliteal fossa and quadriceps tendon.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Interventions<\/jats:title>\n                    <jats:p>After completing 21 sessions of preoperative rehabilitation, the patient underwent right knee surgery consisting of debridement, synovectomy, and cystectomy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Outcomes<\/jats:title>\n                    <jats:p>Pain intensity was assessed using the Visual Analog Scale (VAS), and joint range of motion was recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Although bilateral involvement is rare, SC should be considered in the differential diagnosis of patients presenting with bilateral knee pain and stiffness.
