Recovery periods in the 4-6 week range are ideal and vary, a lot depends on what was done in the repair. Only the surgeon can give the best estimate. Healing includes scar tissue and stability of the corrective action. For example, while true a prosthesis offers firmer support, it must be held in place by screws, wires, plates, sutures etc., and how they adhere factor in the overall strength of the repair. As healing progresses, scar tissue can form improperly, worsening pain. Therefore, the rate of recovery during the 6 weeks determines the future course. A diver should not require cervical collar, rehab, pain medications or have limited lifting restrictions.
