Medial meniscus extrusion (MME) was measured by ultrasonography during knee extension (no weight\u2010bearing with the knee at 0\u00b0 extension: NW0\u00b0) and 90\u00b0 flexion (no weight\u2010bearing with the knee at 90\u00b0 flexion: NW90\u00b0) with the patient in the supine position and with full weight\u2010bearing (FW0\u00b0) preoperatively and at 3 and 12\u00a0months postoperatively.
