Synovial Chondromatosis is a rare disease of the synovial membrane characterised by formation of multiple loose bodies in a joint. Knee is the most common joint to be affected by this disease. Though, this disease can be managed by synovectomy and removal of loose bodies with a favourable functional outcome but in some cases where there is damage of articular cartilage, simple synovectomy might not be sufficient. Here, we present a case of right knee pain in a 53 year old male since 4 years with a established diagnosis of synovial chondromatosis. No other joint was affected. Pain was associated with a fixed flexion deformity and restriction of knee range of motion and multiple slipping bodies. Radiography showed multiple loose bodies in the tibio-femoral as well as in patello femoral compartment. MRI of knee revealed several damaged areas in the knee articular surface. As a result, decision was taken to perform total knee arthroplasty. Intraoperatively all the loose bodies were removed along with the affected synovium and arthroplasty was done. Patient was discharged in fourth post operative day with proper instructions and was called for follow up at 1 month, 3 month, 6 month, 1 year. Functional outcome was assessed by Tegner Lysholm knee score, Knee Society score and Visual Assessment Scale.
Pain around the foot and ankle joint is often misdiagnosed as plantar fasciitis and may lead to delayed diagnosis of osteosarcoma in foot. Delay in diagnosis can lead to adverse prognosis and poor survival outcomes. We present a patient who had primary osteosarcoma of the calcaneum that was initially diagnosed and treated for plantar fasciitis, resulting in a delay of diagnosis. The patient eventually was treated with neo-adjuvant chemotherapy followed by below-knee amputation and adjuvant chemotherapy. This case highlights the need to maintain an index of suspicion with close scrutiny of the radiographs. We suggest few clinical recommendations and need for a great suspicion while evaluating a mass arising from the calcaneum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
