Good bone quality and overall general health are the most important considerations. Age is not usually a factor when determining good candidates for the THINK Surgical procedure.

Contact your insurance provider and consult with your surgeon about coverage.

Although recovery times vary, patients generally resume normal activities within 4–8 weeks.3 To strengthen joints and muscles, the use of canes and walkers is common during the first phases of recovery and most patients work with physical therapists to speed the recovery process.
