What the study found
Adding peripheral stabilization suture (PSS) to conventional transtibial pullout repair was associated with less medial meniscus extrusion, less progression of varus alignment, and less radiographic osteoarthritic change at 1 year after medial meniscus posterior root tear repair.
Why the authors say this matters
The authors conclude that the added PSS technique may better control postoperative structural changes after medial meniscus posterior root tear repair. The study suggests this may be relevant because both groups still showed improvement in patient-reported outcomes, but the PSS group had better structural findings.
What the researchers tested
The researchers retrospectively reviewed patients who had medial meniscus posterior root tear repair between April 2019 and March 2024 and had at least 1 year of follow-up. They compared conventional transtibial pullout repair with pullout repair plus PSS using MRI measures of medial meniscus extrusion, radiographic alignment measures, Kellgren-Lawrence grade, and patient-reported outcome measures.
What worked and what didn't
At 1 year, the PSS group had lower medial meniscus extrusion than the conventional group (3.2 mm vs 5.3 mm). The PSS group also had fewer cases of varus progression and less Kellgren-Lawrence grade progression, while the conventional group showed a medial shift in mechanical axis and a higher rate of clinically meaningful worsening of extrusion.
What to keep in mind
This was a retrospective comparative study with 35 patients and 1 year of follow-up, so the abstract does not describe longer-term outcomes. The abstract does not report detailed limitations beyond the study design and follow-up period.
Key points
- PSS added to transtibial pullout repair was linked to less medial meniscus extrusion at 1 year.
- The PSS group had less varus alignment progression and less Kellgren-Lawrence grade progression.
- Patient-reported outcomes improved in both groups, with no significant difference between them.
- Clinically meaningful worsening of meniscus extrusion was more common in the conventional group.
- The study was retrospective and included 35 patients with 1 year of follow-up.
