Methods Twenty-three patients (24 knees) with symptomatic recurrent subluxation of the lateral meniscus treated by arthroscopic meniscus repair were included. The inclusion criteria were: (1) patients with knee pain, locking or snapping symptoms despite 3 months of conservative treat- ment; (2) non-discoid lateral meniscus; (3) stable knee, and (4) tears involving the red–white or red–red zone. All tears were repaired by either the modified all-inside suture technique only or a combination of the modified all-inside and modified outside-in suture techniques. Clinical results were evaluated preoperatively and at final follow-up according to Tegner activity level, Lysholm knee, and Hospital for Special Surgery (HSS) scores. Results No reoperations were required after a median follow-up of 41 months (range 24–124). Although recurrence of a locking episode was documented in one knee and catching sensations were experienced in three knees, those patients did not require reoperation. At the last follow-up, the median Tegner activity level had improved significantly from 4 (range 2–6) to 7 (range 3–10, p < 0.0001), the median Lysholm knee score improved from 76 (range 25–90) preoperatively to 94 (range 76–100) at final follow-up ( p < 0.0001), and the median preoperative HSS score improved from 86 to 95 at final follow-up ( p < 0.0001).
