Root tears of meniscus

  60 year old lady with sudden onset sharp pain  lt knee. She was previously asymptomatic and very active. clinical exam revealed strong medial meniscal signs  and MRI showed a meniscal extrusion with radial tear adjacent to root.
 she was send for a week of physio and 3 days of NSAID and was reviewed .  she had complete relief and had no meniscal signs and was even able to squat

 After repairing every  root tear  I saw I sometimes think whether I over did the same. Meniscal extrusion remained in at least 3 of the 12 1 repaired in the last 2 years. Pt were definitely asymptomatic.

 To avoid extrusion do we now need to start centralisation sutures like the japs.
Spare a thought guys.
