Thank you for question. An Acromioclavicular (AC) dislocation (shoulder dislocation) usually takes about 4-8 weeks to heal completely. Since it has been 12 months, it is likely that you have made a full recovery. We recommend that before you start doing pull ups or any upper exercises, consult your doctor before starting to make sure the shoulder joint is adequately healed and will not dislocate once more.
