Study shows superior recovery from MIS bunion surgery

LFAC surgeon Anthony Perera has carried out the first study in the world which directly compares outcomes of open and minimally invasive bunion surgery.

The large study, encompassing 240 patients, compares clinical and x-ray outcomes after bunion surgery. It was presented at the recent American Foot and Ankle Society meeting in Florida.

Ten different x-ray measures were analysed, before and after surgery, to assess the quality of correction. It found minimally invasive surgery was equally effective as open surgery, even for the most severe deformities.

“This is an interesting and important finding, which overturns the traditional idea that minimally invasive surgery should only be used for mild to moderate deformities,” comments Mr Perera.

The study also considers clinical outcome scores – in other words, how well patients are doing after their surgery, considering post-operative foot function, pain, ability to wear normal footwear and carry out a range of activities.

On these clinical outcomes for patients, minimally invasive surgery had superior scores to the open approach.

“There was clear evidence to show MIS was superior in terms of minimising swelling and discomfort, improving return to normal foot function and maximum range of motion,” says Mr Perera.
