Inclusion criteria: (1) persistent medial knee joint pain affecting daily life, presenting with joint space tenderness; (2) showing the ineffectiveness of conservative treatment for a minimum of 3 months; conservative treatment includes non\u2010invasive methods such as nonsteroidal anti\u2010inflammatory drugs, physical therapy and massage, but does not include intra\u2010articular injections. (3) Kellgren\u2013Lawrence Grades 0\u2013II osteoarthritis (OA) of the knee joint; and (4) diagnosis of a posterior root tear of the medial meniscus with notable meniscus extrusion confirmed through knee\u2010joint plain magnetic resonance imaging (MRI) scans, where coronal image revealed a meniscus body extrusion of \u22653\u2009mm. Exclusion criteria: (1) Kellgren\u2013Lawrence Grades III\u2013IV OA in the knee joint; (2) presence of knee joint infection or other structural damage to the knee joint; (3) history of previous knee joint surgery; (4) demonstrating joint instability or abnormal lower\u2010limb alignment (varus deformity &gt;5\u00b0); and (5) presence of severe mental illness, coagulation disorders, or other serious medical conditions. The Lysholms score, the Hospital for Special Surgery (HSS) knee score, the visual analogue scale (VAS) score and meniscal extrusion values were evaluated before and after surgery in 23 patients through a comparative analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The results of the follow\u2010up conducted 12\u201314 months post\u2010operatively indicated a significant improvement in the patients' conditions.

Furthermore, compared to the preoperative values, the degree of meniscus extrusion measured by coronal MRI of the knee joint significantly improved post\u2010operatively (preoperative: 3.7\u2009\u00b1\u20090.8\u2009mm; 1\u2010year post\u2010surgery: 2.2\u2009\u00b1\u20090.6\u2009mm).
