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.
