Associations of surgical and nonsurgical weight loss with knee musculature: a cohort study of obese adults

Compared with nonsurgical weight loss, laparoscopic gastric banding was associated with greater VM muscle thickness loss. Relative to laparoscopic gastric banding, there was also a tendency toward an increased risk for VM fat infiltration to be reduced with nonsurgical weight loss. Close attention to preserving muscle properties at the knee when significant amounts of weight loss have occurred is required. Physical therapy may be important in the management of patients after laparoscopic gastric banding in an attempt to preserve skeletal muscle mass.
