Patellar Tendinopathy (also called jumperβs knee) is an overuse injury of the patellar tendon, the thick band that connects your kneecap (patella) to your shin bone.
πΉ What happens
π The tendon becomes:
Irritated
Degenerated (tiny micro-tears over time)
Weak and painful
π Itβs usually caused by repetitive stress, not a single injury.
πΉ Common symptoms
π You may feel:
Pain just below the kneecap
Pain during jumping, running, or squatting
Stiffness in the knee (especially after rest)
Tenderness when pressing the tendon
Pain that improves with warm-up but worsens after activity
πΉ Who gets it?
π Common in:
Athletes (basketball, volleyball, running)
People who jump, squat, or run frequently
People with tight leg muscles or poor biomechanics
πΉ Causes & risk factors
π Includes:
Overuse or sudden increase in activity
Tight quadriceps or hamstrings
Poor landing or jumping technique
Weak glutes or core muscles
Hard training surfaces
πΉ How it differs from other knee pain
π Unlike arthritis:
Pain is localized to the tendon
Not mainly joint-related
π Unlike ligament injury:
No sudden instability
Develops gradually over time
πΉ Treatment & recovery
π Main approach = load management + strengthening
β Reduce activities that cause pain (jumping, deep squats)
β Ice after activity
β Physical therapy
β Strengthening exercises (especially slow, controlled movements)
β Stretching of quads and hamstrings
πΉ Helpful exercises
π Common rehab exercises:
Eccentric squats (slow lowering)
Step-down exercises
Isometric holds (wall sits)
Glute strengthening
β οΈ When to see a doctor
π Seek help if:
Pain persists for weeks
Severe limitation in movement
Swelling or worsening pain
Difficulty walking or bearing weight
πΉ Simple summary
π Patellar tendinopathy =
βOveruse injury of the knee tendon below the kneecap causing pain during activity, especially jumping and squatting.β
