Which findings predict a poorer course after nonoperative treatment of a meniscal root tear?

Radiographic OA progressed in 34 patients (36%); 12 (13%) underwent arthroplasty during follow-up.

The research question

Which findings predict a poorer course after nonoperative treatment of a meniscal root tear?

Participants and Methods

Prospectively collected data from patients treated nonoperatively for acute medial posterior root tears were analysed retrospectively. KL changes and conversion to arthroplasty were tracked, with SIFK assessed on baseline MRI. There were 94 patients, mean age 67.0 years and mean follow-up 46.1 months: 90 women and four men.

Main Findings

Radiographic OA progressed in 34 patients (36%); 12 (13%) underwent arthroplasty during follow-up. SIFK was associated with a relative risk of arthroplasty of 4.08 (95% CI 1.23–13.57). Pain and function scores did not differ significantly between initial and final follow-up.

Implications for clinical and surgical practice

This supports checking for SIFK on MRI when discussing treatment and follow-up for root tears. The study used measurement software; Du Hyun Ro was not a coauthor.

Limitations

This selected nonoperative cohort was not randomised against root repair. Its prognosis cannot be generalised to all root tears. Radiographic progression, pain changes and conversion to arthroplasty are distinct outcomes. The wide confidence interval also warrants attention.

Let's put it briefly.

Which clinical question does this address?
