Conditions

Excessive Lateral Pressure Syndrome

Keywords

excessive lateral pressure syndrome; patellofemoral joint; tibiofemoral joint

Outcome Measures

Primary Outcomes (1)

• Change of lesions

  The improvement of cartilage injury of patellofemoral joint and tibiofemoral joint. Two senior surgeons read the MRI separately, recording the status of lesion area. The lesion area was compared before and after surgery. Using Outerbridge Classification to evaluate the severity of cartilage injury.

Secondary Outcomes (2)

• Clinical symptom change

  2years

• Pain severity

  2years

Study Arms (2)

observation group

People suffered from excessive lateral pressure syndrome with extracapsular release of lateral retinaculum.

Procedure: extracapsular release of lateral retinaculum

control group

People suffered from excessive lateral pressure syndrome with conservative treatment.

Interventions

extracapsular release of lateral retinaculum PROCEDURE

A new kind of surgery which releases the lateral retinaculum from outside the knee capsular, maintaining the structure of the knee capsular.
