✅ Injury Patterns

1️⃣ Partial Ruptures of the Medial Retinaculum: These injuries can occur at the inferomedial patella.

2️⃣ Complete Tears of the Medial Retinaculum: In these cases, the injury extends proximally into the region typically defined as the MPFL patellar insertion. The medial retinaculum encompasses both the MPFL and the MPTL, resulting in a complete tear (Am J Sports Med, 2018).

3️⃣ Extension of Tears to the Patellar Tendon: Due to the close proximity of the MPML and MPTL attachments to the patellar tendon and patellar articular cartilage, complete tears of the medial retinaculum can extend and involve the patellar tendon.

 

✅  Distal Medial Patellar Restraints: MPML and MPTL

• The MPML and MPTL extend from the inferomedial patella to the medial meniscus and anteromedial tibia, respectively. 
• The current study has revealed the close proximity of the MPTL and MPML attachments to the patellar tendon and patellar articular cartilage (Radiographics, 2023).
