title: Arthroscopic meniscus repair for recurrent subluxation of the lateral meniscus.
abstract: OBJECTIVE
  This study was undertaken to diagnose and to document the clinical results and technical aspects of arthroscopic meniscus repair for recurrent subluxation with peripheral tears around the popliteal hiatus of the lateral meniscus.
  
  
  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 treatment; (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).
  
  
  CONCLUSIONS
  The described arthroscopic meniscus suture technique is effective for treating symptomatic recurrent subluxation of the lateral meniscus without any complications or recurrence. Clinical suspicion and understanding of recurrent subluxation with lateral meniscus are important to diagnose the disease especially when definite meniscal tear signs are absent on magnetic resonance imaging.
