Abstract

Objectives: Was to evaluate the clinical and functional outcomes of combining lateral extra-articular tenodesis with arthroscopic anterior cruciate ligament reconstruction in treatment of high grade anterolateral rotational knee instability. Background: Lateral extra-articular tenodesis with arthroscopic anterior cruciate ligament reconstruction in treatment of high grade anterolateral rotational knee instability grants equivalent isokinetic muscle recovery as does stand-alone anterior cruciate ligament in knees with no rotational instability. Methods: This study was conducted on twenty patients with anterolateral knee instability. Lateral extra articular tenodesis using iliotibial band distally attached and fixed to lateral femoral epicondyle with intra articular arthroscopic anterior cruciate ligament reconstruction by hamstring tendons grafts. They were finally assessed by hospital for special surgery (HSS) Scoring scale. Results: Among the 20 patients in this study,18 were males and 2 were females. Fifteen (75%) patients had excellent and good results postoperatively. HSS Score was significantly increased post operatively 78.10 ± 7.62 (Good) with a range score between 64 – 87 than preoperatively, 55.45 ± 2.98 62 (Worse) with a range score between 52 – 60. Conclusion: the addition of a lateral extra-articular tenodesis to an intra-articular ACL reconstruction in rotational knee instability management improves stability outcomes without compromising muscle recovery at the time of return to activity. It also can reduce graft rupture rate and has the same postoperative regime as an isolated ACL reconstruction.
