A systematic review of tibial stem extensions in patients with obesity undergoing total knee arthroplasty

Key Points

• Tibial stem extensions enhance joint stability in total knee arthroplasty patients with obesity, providing significant biomechanical advantage.
• Evidence indicates improved postoperative outcomes and reduced complications associated with tibial stem extensions in this population.
• Systematic review approach evaluated multiple studies related to tibial stem applications and outcomes in patients with obesity.
• Findings support the potential for better surgical results and patient satisfaction through the use of tibial stem extensions.
