Total Knee Arthroplasty
A 68-year-old woman with severe varus osteoarthritis undergoes total knee arthroplasty. After bone cuts, the surgeon notes that the extension gap is tight medially with 5mm asymmetry, and the flexion gap is also tight but symmetric. Trial components show good stability in extension but restricted flexion to only 90 degrees. The surgeon considers the ligament balancing sequence and gap troubleshooting algorithm.
