|Failed Anterior Cruciate Ligament Reconstruction with Residual Laxity|
Your diagnosis is a failed anterior cruciate ligament (ACL) reconstruction with persistent laxity.
Injury or Condition
This condition represents a permanent deformation of the graft tissue which was previously used for reconstruction of the ACL. Its failure may lead to failure of cartilage repair procedures or to new injury.
Common causes of ACL failure include suboptimal positioning of the graft or incomplete healing (incorporation) of the graft. Failure of the graft is sometimes associated with use of cadaver tissue. Other associated ligament insufficiencies, like attenuation of the medial collateral ligament, may be present. The graft may also stretch out because of inadequate protection during the first six months of recovery. Occasionally, the reason for failure may not be discernable.
Typical symptoms are a return of giving way (instability) that can be confirmed by laxity measurements. Loss of strength after the previous surgical intervention may be difficult to regain. Pain about the kneecap (patella) may be present.
Standard treatment includes:
Expected recovery time for this condition is dependant upon the treatment option. At times a bone grafting procedure (stage 1) must be performed prior to revision ligament surgery (stage 2) with an interval of about 3-6 months between procedures. Once the ligament revision is complete, the rehabilitation prepares you for return to sports activities or heavy labor after 6 months.
