Posterior cruciate ligament recession

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Knee Biomechanics

Background:

• Posterior cruciate ligament (PCL) injuries are common knee ligament injuries.
• PCL laxity can lead to significant knee instability and functional deficits.
• Assessing PCL integrity and associated instabilities is crucial for effective treatment.

Observation:

• Three cases of PCL laxity without evidence of posterolateral rotatory instability were identified.
• Magnetic resonance imaging (MRI) confirmed the structural continuity of the PCL in all cases.
• Patients presented with symptomatic knee laxity despite intact PCL structures.

Findings:

• Tibial PCL recession was performed as a surgical intervention.
• The procedure effectively eliminated symptomatic laxity in one patient.
• Two patients did not experience significant improvement in laxity following tibial PCL recession.

Implications:

• This suggests that PCL laxity can manifest even with an intact PCL, challenging traditional diagnostic paradigms.
• Tibial PCL recession may be a viable option for select cases of PCL laxity.
• Further research is needed to elucidate the underlying mechanisms of PCL laxity and optimize treatment strategies.
