Correction of Sagittal Deformity with Bone Resection and Soft Tissue Releases

Abstract

Fixed flexion deformities (FFDs) present several unique challenges in total knee arthroplasty (TKA) and require careful consideration to achieve optimal outcomes. FFD alters normal knee biomechanics and increases energy expenditure. They may be attributed to both bony deformities and fibrosed soft tissues, which must be addressed in stepwise fashion at the time of surgery. A literature review was conducted utilizing keywords “fixed flexion deformity TKA.” This review article aims to discuss the anatomy and pathology, preoperative evaluation, classification system, surgical techniques for addressing deformity, implant selection considerations, postoperative protocols, clinical outcomes, and potential complications associated with correcting FFD. By comprehensively addressing these aspects, surgeons can optimize surgical planning and improve outcomes in patients with FFD undergoing TKA.
