Patellar Dislocations
Treatment of Patellar Dislocations
Reduction Immobilization Immediate treatment of patellar dislocations is reduction; most patients do not require sedation or analgesia. Reduction is done with the patient's hip flexed. Then practitioners gently move the patella medially while simultaneously extending the knee. When the patella is reduced, a palpable clunk is usually evident and the deformity resolves. (See also How To Reduce a Lateral Patellar Dislocation .) Immediately after reduction, the knee can be checked for stability by moving it through its range of motion (flexion and extension). If the knee is stable, treatment consists of crutches and an elastic wrap. If the knee is unstable, a knee immobilizer is needed. Patients with osteochondral injury or recurrent instability may require a referral to an orthopedic surgeon for outpatient surgery.
