Abstract
Introduction
The patients who undergo Anterior Cruciate Ligament reconstruction (ACLR) should delay return to sport if they have not recovered muscle strength after surgery. Adjunct surgical procedures with ACLR such as the Lateral Extraarticular Tenodesis (LET) adds knee stability but potentially can delay recovery in strength. We wanted to study whether adding an LET to ACLR affects strength recovery after surgery. This has not been well studied.
Objectives: The aim of this study is to compare quadriceps and hamstring muscles strength recovery between patients who underwent isolated ACLR versus patients underwent ACLR with LET.
Methods
All patients who underwent primary hamstring autograft ACLR from 2021 were studied. We excluded all patients who underwent revision ACLR and multiligament reconstructions. The patients were divided into two groups; patients underwent ACLR only (Group 1), and ACLR with LET (Group 2). All patients underwent Biodex isokinetic dynamometer assessment for knee extensors and flexors strength at six and twelve months after the surgery. Both sets of patients underwent the same rehabilitation programme after surgery.
Results
A total of 65 patients included in the study; 19 patients underwent ACLR only (Group 1), 46 patients underwent ACLR with LET (Group 2).
At six months, the patients ACLR with LET (Group 2) had better knee extensor and flexor strength. (P<0.05 except for 60 deg/s knee extensor). At one year, the patients ACLR with LET (Group 2) also had better knee extensor and flexor strength (P<0.05). The knee extension deficit recovery was poorer that knee flexion deficit recovery at both six months and one year (P<0.05).
Having a concomitant meniscus repair did not influence muscle strength in both groups at six months and one year (P>0.05).
Conclusion
Adding an LET to ACLR does not worsen quadriceps and hamstring recovery at six months and one year after ACLR. Conversely, we see that the addition of the LET gives the confidence to help our patients regain strength at a faster rate.
