To answer your question, it depends on what type of elbow surgery you’re referring to. It can either be a fracture , ligament, tennis elbow/ tendinous surgery or a combination of all - both bony and soft tissue. An elbow arthroscopic debridement May have a quicker healing and recovery time.
Complete healing usually takes 2-3 months, and post-op physiotherapy and rehabilitation is extremely important for elbow surgery. This is to prevent stiffness and get back the range of movement. I would recommend you to seek a consult with your Orthopaedic surgeon, to find out exactly what procedure you would be undergoing, to have a better idea of the whole picture.
