The Effect of Lateral Extra-Articular Tenodesis on Lower-Extremity Lean Mass Recovery Following Anterior Cruciate Ligament Reconstruction

The Effect of Lateral Extra-Articular Tenodesis on Lower-Extremity Lean Mass Recovery Following Anterior Cruciate Ligament Reconstruction: A Randomized Controlled Trial

The purpose of this study is to determine whether the addition of Lateral Extra-Articular Tenodesis (LET) influences postoperative lower-extremity LM recovery following bone-patellar tendon-bone (BTB) Anterior Cruciate Ligament Reconstruction (ACLR). We hypothesize that patients undergoing ACLR BTB with LET will demonstrate greater loss of operative-leg LM at 9 months postoperatively compared with patients undergoing isolated ACLR BTB.

Inclusion Criteria:

• Skeletally mature patients less than or equal to 60 years of age with ACL insufficiency scheduled to undergo primary BTB ACL reconstruction with or without LET.
• Patients presenting with acute ACL injuries. Patients presenting with acute ACL injuries will be eligible for enrollment.
• Acute injuries will be defined as injuries occurring within 6 weeks of presentation.

Exclusion Criteria:

• undergoing multi ligamentous reconstruction (PCL, MCL, or PLC)
• revision ACL reconstruction
• neuromuscular disorders
• contralateral ACL injury
• pregnant or nursing
• unable to read or write in English
• possessing a high likelihood of remaining non-compliant
• desire to return to sport prior to 6 months.
