Wound granulomas are common, and settle when the offending suture is removed.
Swollen calves after orthopaedic surgery are common. If worried, then ultrasound is an easy and safe investigation. Most below knee DVTs do not need treating specifically, but we would be happy to advise at any time.
Increasing swelling, pain, limitation of movement and wound drainage indicate infection could be a possibility. If worried please contact the rooms. We would rather see patients if possible, than empirical treatment to be started. CRP and ESR would be useful tests to do. Wound swabs are not useful as they represent contaminant skin flora.
