Knee Tendonitis/Instability

This is a Mild / Moderate condition.

Tendonitis is when a tendon becomes inflamed and becomes painful after a tendon injury. You can treat mild tendon injuries yourself and should feel better within 2 to 12 weeks.


  • Pain and discomfort around the knee
  • Swelling
  • Occasional tingling
  • Tightness of the calf muscle when completing activities.
  • Increase risk of cramps in the calf.
  • Reduced movement when trying to bend the knee.
  • Increased temperature of the skin knee.

Total Body Orthotics offers face-to-face clinical assessments for the provision, measurements and fitting of a wide range of orthotic devices from insoles to fully customised Knee Ankle Foot Orthosis (KAFOs). Appointments are based at our clinic at The Arcade, High Street, Eccleshall , Staffordshire, ST21 6BZ. There is a £50 assessment fee to access this service.

If you have purchased a device from us and are struggling with fitting or wear we also provide free online Zoom consultations with our orthotist where we can provide remote support and advice where possible.

If you have any questions please contact a member of the team using our online enquiries form or by emailing

Recovery Time
2-3 Weeks
Self Treatable
There is a wide variety of symptoms for this medical condition.
  1. Rest – stop the exercise or activities that caused the injury until you feel better
  2. Ice – put an ice pack (you could use a bag of frozen peas wrapped in a tea towel) on the injury for up to 20 minutes every 2 to 3 hours
  3. Compress – wrap a bandage around the injury to support it
  4. Elevate – if possible, keep the injured area raised on a pillow when sitting or lying down

To help prevent swelling during the first 2 to 3 days, try to avoid:

  • heat, such as hot baths and heat packs
  • alcohol
  • massages

When you can move the injured area without pain stopping you, try to keep moving it so the tendon doesn’t become stiff.
