Preventing a meniscus tear

Why prevention matters

A meniscus tear can settle down, but the knee can stay sensitive for a while, especially with twisting, deep bending, or sudden increases in activity. Many people also feel nervous about their knee “catching” or giving way, which can lead to avoiding movement and losing strength over time. Keeping the knee strong and gradually staying active can help you move with more confidence and may reduce how often symptoms flare up.¹ ²

It also helps to remember that meniscus tears are common, and many tears seen on MRI also appear in people who do not have knee pain. Your symptoms and how you function matter as much as imaging findings.¹

Managing a meniscus tear: What can trigger flare-ups?

Common things that can irritate a healing or sensitive knee include:

  • Sudden twisting or pivoting, especially on a bent knee, such as quick turns with a planted foot.³
  • Deep knee bending under load, like heavy squats, kneeling, or low chairs, especially if you have not built up to it.²
  • Doing too much too soon, such as a sharp increase in walking, running, sport, or hills after a quieter period.²
  • Swelling and stiffness after activity, which can make the knee feel tight, weak, or unreliable.²
  • Weakness in the thigh and hip muscles, which can increase stress on the knee during stairs, squats, and direction changes.²
  • Arthritis-related irritation in the knee, which often overlaps with degenerative meniscus tears and can drive pain and swelling.⁴ ⁵

Habits that help prevent flare-ups

  • Build up activity in small steps: Gradually increase walking, stairs, running, or sport. Sudden jumps in load are a common reason symptoms return.²
  • Strengthen the thigh and hip muscles: Strong quadriceps and hips help the knee handle daily demands with less strain.²
  • Practice controlled knee-bending movements: Exercises like sit-to-stands, step-downs, or shallow squats help prepare the knee for real-life tasks when progressed slowly.²
  • Use a 24-hour check after harder days: Mild soreness during activity can be normal, but swelling or a pain spike that lasts into the next day is a sign to scale back.²
  • Limit sharp twisting early on: Reduce pivoting and sudden direction changes at first, then reintroduce them gradually as strength and confidence improve.³
  • Treat swelling as information, not failure: Swelling is a sign the knee needs a short adjustment in load, not that damage is occurring.²

How Sword supports ongoing strength and mobility

Move is a guided movement program designed to help you stay active by building strength, improving mobility, and supporting stable movement patterns over time. It’s often used after recovery from a flare-up to help maintain progress and support long-term movement health.

Sword offers movement support that fits into daily life, helping you continue building strength and mobility over time. Programs are guided by expert insight and supported by technology designed to help you stay consistent.

  • Focus on strength, mobility, and stability
  • Designed to support movement between flare-ups
  • Guided programs you can follow on your schedule
  • Non-invasive, evidence-informed approach
