Tear length associated with meniscal tear healing after inside-out suturing

Researchers from Istanbul saw high rates of healing when single or double vertical sutures and an inside-out arthroscopic technique were used to treat partial-thickness or full-thickness longitudinal medial meniscal tears.
Few studies describe the healing rates of these types of meniscal tears that were treated with single or double vertical sutures, based on the study, which looked at results in 112 patients with longitudinal medial meniscal tears. Outcome measures used included clinical resolution of symptoms, the Lysholm knee and Tegner activity scales and postoperative MRI.
Arthroscopic evaluation showed that 85 tears were >2 cm long and 27 tears were ≤2 cm long. All the patients underwent ACL reconstruction and had a mean follow-up time of 49.3 months. There were 66 patients with full-thickness tears and 46 patients with partial-thickness tears.
In all, 99 tears healed and 13 tears failed to heal for a healing rate of 80.3% in the full-thickness group and 100% in the partial-thickness group. From preoperative to postoperative time points, mean Lysholm scores increased from 63.8 points to 89.5 points and mean Tegner activity scale scores improved from 3.3 points to 6.7 points. The logistic regression analysis indicated concurrent ACL reconstruction, tear length and smoking were significantly associated with healing of longitudinal medial meniscal tears.
