Knee surgery study questions need for extra ligament release

This study looked at whether cutting a small ligament on the outside of the knee (lateral retinaculum release) is helpful during a common surgery for recurrent kneecap dislocation. The surgery, called MPFL reconstruction, already tightens the inner ligament to keep the kneecap in place. The study included 140 people aged 18 to 45 who needed this surgery. Researchers measured kneecap tilt and complication rates to see if the extra release made a difference.
