Significantly smaller lateral extrusion was observed within 24 weeks after all-inside suture repairs of radial tear in the middle segment of lateral meniscus compared to inside-out repairs
Purpose
To evaluate the postoperative meniscal extrusion between all-inside suture (AIS) and trans-capsular suture (TCS) repair techniques.
Methods
Thirteen patients (mean age, 19.4 years) underwent AIS repairs using only sutures (AIS group) for radial tears in the middle segment of the lateral meniscus (RTMLM), and seven patients (mean age, 20.3 years) underwent inside-out repairs among TCS (TCS group). For all cases, lateral (LE), anterior (AE) and posterior (PE) meniscal extrusions of the lateral meniscus were measured during preoperative and 3-, 12- and 24-week postoperative MRIs. Then, the change of each extrusion from preoperative to each postoperative period was calculated as ∆LE, ∆AE and ∆PE.
Results
There was no significant difference between the AIS and TCS groups in the preoperative extrusions. As for postoperative extrusions, only ∆LEs in the AIS group was significantly smaller than those in the TCS group at all postoperative periods (−1.5 ± 1.7 vs. 0.9 ± 0.7 mm at 3-week, −0.9 ± 0.9 vs. 0.4 ± 0.9 mm at 12-week and −0.3 ± 1.0 vs. 0.6 ± 1.1 mm at 24-week postoperation). In ∆AEs and ∆PEs, at all three postoperative periods, there were no significant differences.
Conclusion
Postoperative LE, AE and PE on MRIs after AIS and TCS repairs for RTMLM were investigated. Significantly smaller lateral extrusion was observed within 24 weeks after AIS repairs of RTMLM compared to TCS repairs, which could lead to stabilization of the repair site and prevent degenerative changes.
