Patellar Tendinitis

Also known as “jumper’s knee,” patellar tendinitis is an overuse injury affecting the tendon connecting your kneecap to your shinbone.

What is Patellar Tendinitis?

Patellar tendinitis is inflammation of the patellar tendon, which runs from your kneecap (patella) to your shinbone (tibia). This tendon works with the muscles at the front of your thigh to extend your knee for kicking, running, and jumping.

The condition is common in athletes whose sports involve frequent jumping, hence the nickname “jumper’s knee.” However, anyone can develop patellar tendinitis, especially with sudden increases in physical activity.

Symptoms

  • Pain at the base of the kneecap
  • Pain that worsens with jumping, running, or climbing stairs
  • Stiffness in the knee, especially after sitting
  • Swelling around the patellar tendon
  • Weakness in the affected leg
  • Pain that increases with activity over time

Risk Factors

  • Sports involving jumping (basketball, volleyball)
  • Running and track activities
  • Sudden increase in training intensity
  • Tight leg muscles (quadriceps, hamstrings)
  • Leg muscle imbalances
  • Hard playing surfaces

Stages of Patellar Tendinitis

Stage 1

Pain only after activity, doesn’t affect performance

Stage 2

Pain during and after activity, but still able to perform

Stage 3

Prolonged pain that affects performance

Stage 4

Complete tendon tear requiring surgical repair

Treatment Options

Most cases respond well to conservative treatment with proper rehabilitation.

Rest & Activity Modification

Reducing or modifying activities that aggravate symptoms

Physical Therapy

Eccentric strengthening exercises and stretching programs

Patellar Tendon Strap

A strap worn below the kneecap to reduce stress on the tendon

PRP Injections

Platelet-rich plasma therapy to promote healing

Surgery

Rarely needed; for cases that don't respond to conservative treatment

Key to Recovery

Early treatment is crucial. Continuing to push through the pain can lead to chronic tendinopathy or complete tendon rupture. An eccentric strengthening program under the guidance of a physical therapist is often the most effective treatment for patellar tendinitis.
