Knee pain is very common – in fact, it’s one of the leading causes of musculoskeletal complaints, especially in adults over 45. Here are some key facts:

How Common Is Knee Pain?

  • Around 1 in 4 adults experience chronic knee pain at some point.
  • It’s most commonly caused by osteoarthritis, injury, overuse, or biomechanical issues.
  • Women and people over 50 are more likely to develop knee issues due to hormonal, structural, and lifestyle factors.
  • In fitness populations, knee pain can result from poor form, muscle imbalances, or tightness in the hips and ankles.

Good Exercises for Clients with Knee Pain

  • Glute bridges – Strengthen hips and glutes with minimal knee pressure
  • Clamshells / side-lying leg lifts – Target glutes medius for knee tracking
  • Standing balance work – Improves proprioception and lower limb control
  • Wall sits (short hold) – Strengthens quads in a static, controlled way
  • Seated leg extensions (no weight) – Helps regain control through range
  • Supine hamstring work (with ball or band) – Builds posterior chain strength
  • Gentle stretching for quads, hamstrings, calves, and hip flexors
  • Breathwork & pelvic stability – Supports overall posture and movement integrity

Exercises to Avoid or Modify

  • Deep squats and lunges (especially unsupported)
  • Repetitive jumping or hopping
  • High-impact drills or HIIT-style transitions
  • Fast-paced directional changes
  • Prolonged kneeling – unless cushioned or supported
  • Overly flexed knee positions – in clients with arthritis or meniscus issuesHigh-
  • Fast-paced directional changes
  • Prolonged kneeling – unless cushioned or supported
  • Overly flexed knee positions – in clients with arthritis or meniscus issues

Knee Pain in Fitness Pilates: Causes, Challenges and Class Considerations

Common Causes of Knee Pain

  • Muscle imbalances – Weak glutes, tight hamstrings or quads, or underactive inner thighs can all affect knee alignment.
  • Poor movement mechanics – Overuse, poor squat technique, or misalignment in everyday activities can strain the joint.
  • Lack of mobility – Stiff ankles or hips can force the knee to compensate, leading to pain.
  • Injury or degeneration – Meniscus tears, ligament damage, arthritis, or previous trauma.
  • Overload – Excessive jumping, repetitive high-impact exercise, or sudden changes in activity levels.

Fitness Pilates: What You Can Do

Fitness Pilates can be incredibly beneficial when taught with care and awareness of the knee joint. Focus on improving:

  • Hip and ankle mobility
  • Glute, hamstring, and core strength
  • Knee tracking and alignment in movement
  • Functional movement patterns

When Does Someone Need a Knee Replacement?

A knee replacement (total or partial) is typically recommended when:

  • Severe arthritis or joint damage: Often due to osteoarthritis, rheumatoid arthritis, or trauma.
  • Persistent pain: Pain that doesn’t improve with physiotherapy, medication,
    or lifestyle changes.
  • Loss of function: Difficulty walking, climbing stairs, or standing for prolonged periods.
  • Reduced quality of life: Pain interferes with sleep, mood, independence, or daily activities.
  • Visible joint changes: Swelling, deformity, or restricted movement.
