Risk factors for Operative Treatment
In the absence of reliable evidence, it is the opinion of the work group that although operative treatment is an option, it should be approached more cautiously in patients with diabetes, neuropathy, immunocompromised states, age above 65, tobacco use, sedentary lifestyle, obesity (BMI > 30), peripheral vascular disease or local/systemic dermatologic disorders.

Rationale
Rupture of the Achilles tendon occurs not only in healthy active individuals, but also in those with substantial medical histories.  We were unable to find any published studies that addressed the effects of co-morbid conditions on the success of operative repair.  Therefore, this recommendation is based on expert opinion, and is consistent with current clinical practice. 

The consensus of the work group is that consideration of non-operative treatment should occur before performing operative repair of Achilles tendon ruptures in those individuals with conditions that may impair wound healing.  These individuals may be at increased risk for wound problems and infection with subsequent detrimental effect on outcome.
