Abstract
Introduction: Meniscal root tears can lead to earlier onset of osteoarthritis; repair of these injuries is crucial for the prevention of arthritic changes. There is limited literature regarding meniscal root repair(MRR) techniques and their outcomes. The purpose of this study is to report minimum one-year outcomes of transosseous pull-out MRR technique performed by two surgeons at our institution.
Materials and Methods: Retrospective chart review identified patients who underwent primary MRR during 5-year period(2013-2017), performed by two board certified orthopaedic surgeons using the same technique. Patients with concomitant ligament repairs were excluded. Identified patients were asked to complete the IKDC form and Lysholm. Patients also reported any subsequent procedures on the operative knee.
Results: A total of 75 patients were identified and 57 completed follow-up. 7 patients underwent subsequent knee arthroplasty. The mean age was 52.52(+/- 10.81) years and mean BMI was 32.35(+/- 6.07) kg/m2 for the study population. Mean follow-up survey was conducted at 41.27(+/- 16.99) months post operatively, ranging between 18 and 88 months. There was a significant improvement between pre-operative and post-operative outcome scores measured on the IKDC(P<0.01), Lysholm(P<0.01). Age(P=0.11, P=0.30), BMI(P=0.23, P=0.06), gender(P=0.21, P=0.40), and follow-up time(P=0.43, P=0.72) was not associated with worse outcomes on the IKDC or Lysholm, respectively. Worse pre-operative Kellgren-Lawrence grades was associated with worse outcomes on the IKDC(P<0.01) and Lysholm(P<0.01).
Conclusion: Our technique of meniscal root repair is effective at achieving positive clinical outcomes in patients with meniscal root tears(regardless of demographic factors) with low conversion rates to total knee replacement.
