| 1 | Extensive adhesion formation in a total knee replacement in the setting of a gastrointestinal stromal tumor:A case report显示文摘BACKGROUND Gastrointestinal stromal tumors(GISTs)are rare primary neoplasms of the gastrointestinal tract,accounting for 1%to 2%of all gastrointestinal neoplasms worldwide.GISTs are frequently discovered incidentally during workup for other diagnosis or intestinal obstruction,as they can present with few or no symptoms.Simultaneously,GISTs confer a high degree of malignant transformation,with a progression in about 10%to 30%of cases.CASE SUMMARY A 63-year-old healthy female presented to our institution with complaints of right knee pain and limited passive and active motion in the setting of a previous right total knee arthroplasty(TKA).One year after TKA,the patient was incidentally diagnosed with a GIST,which was successfully removed.After removal,the patient continued to have limited range of motion of the right knee and subsequently underwent revision TKA.Intraoperatively significant fibrotic adhesions were found encapsulating the femoral and tibial components.The patient’s pain improved postoperatively,however,she continued to have decreased range of motion with difficulty ambulating.CONCLUSION We propose that this case may demonstrate a proinflammatory milieu arising from a GIST,which had a direct influence on the outcome of recent total knee arthroplasty.This proposed mechanism between neoplastic cytokinetic activity and adhesion formation could have implications on preoperative and postoperative orthopedic management of total knee arthroplasty. | Steven Mitchell Anderson Lee Ryan Stenquist David YatsonskyⅡ Megan L Mooney Vithal B Shendge | 2022 | World Journal of Orthopedics2022，13，5： | 0 |
