Recently, successful clinical outcomes for symptomatic discoid lateral meniscus (DLM) have been reported following partial meniscectomy (saucerization) with repair. In contrast, some studies using radiography and magnetic resonance imaging (MRI) have suggested that function of load transmission might not be appropriately maintained after saucerization with repair. Therefore, in pursuit to uphold load transmission after surgery for DLM, this study tried to preserve the DLM shape to keep the original DLM function. Discoid lateral meniscus repair without saucerization was indicated, with strict criteria, for those who had a painful peripheral longitudinal tear with purely intact body caused after a single traumatic incidence. The repair was performed without saucerization for four adolescents (two males, two females; mean age 16.2 years; three complete types of DLM, and one incomplete type of DLM). Postoperatively, the following were evaluated with radiography and MRI at six, 12, and 24 months after surgery: clinical outcomes, degenerative changes, and morphology of repaired DLM. They all showed good clinical outcomes. Furthermore, no degeneration, deformation, nor extrusion was observed at the two-year follow-up after surgery. For limited cases of DLM, as mentioned above, DLM repair without saucerization can be one treatment option.

Radial Tear of the Midbody in Complete Discoid Lateral Meniscus: A Case Report.

To the best of our knowledge, there are no reports on the results of the repair of radial tears of the midbody of the complete discoid lateral meniscus (DLM). A 14-year-old female underwent meniscal replacement with autologous tendon transplantation for early re-tear after repair of the radial tear in the midbody of complete DLM. Two years after the tendon transplantation, there was no effusion or swelling, and the patient was able to exercise completely without symptoms.

An incomplete discoid lateral meniscus is often associated with radial tears, which cause meniscal extrusion and result in poor healing outcomes. Centralization has recently been used as a surgical method to reduce extrusion. However, various repair techniques use single point of fixation sutures exclusively on the femoral side, potentially hindering healing.

Case: A 4-year-old girl with no relevant medical history presented with left knee swelling. Knee laxity, magnetic resonance imaging findings of anterior cruciate ligament (ACL) deficiency and discoid meniscus, and the chronicity of symptoms prompted arthroscopic ACL reconstruction and meniscal saucerization. Pain and swelling continued, and repeat arthroscopy revealed regeneration of the discoid meniscus at 18-month follow-up.

Article Synopsis
- The study compared the effectiveness of two surgical techniques (outside-in vs. all-inside suturing) for treating discoid lateral meniscus injuries, involving 30 patients in each group.
- Results showed that the all-inside suturing group had better clinical outcomes, including shorter operation times and lower pain scores post-surgery.
- Factors influencing treatment success included operation duration, knee scores at six months, and the type of suturing method used.

Article Synopsis
- * The study hypothesized that arthroscopic repair of lateral meniscal tears, specifically involving the popliteus tendon, would lead to low reoperation rates and better clinical outcomes.
- * Results showed significant improvements in knee function and decreased widths of the popliteal hiatus and lateral meniscus extrusion after surgery, with only five patients needing reoperation within the follow-up period.
