Patellar tendinitis, better known as jumper’s knee, is pain in the tendon that connects your kneecap to your shin bone. It shows up as a sharp, well localised ache just below the kneecap that hurts when you jump, land, squat or climb stairs. It is common in volleyball, basketball, soccer and any sport with repeated jumping, and it also affects people who ramp up running or lifting quickly. This page covers what is actually happening in the tendon, what helps, and how our Mississauga team treats it.
What Is Jumper’s Knee?
The patellar tendon transfers force from the quadriceps through the kneecap to the shin so you can straighten your knee, jump and absorb landings. When the load you place on it repeatedly exceeds what it has been prepared for, the tendon structure starts to change. Clinicians now describe this as tendinopathy rather than simple inflammation, because the tissue shows disorganised collagen and increased fluid rather than a classic inflammatory response. That distinction matters, since it explains why rest alone rarely fixes it. Tendons respond to graded load.
Symptoms That Point to the Patellar Tendon
- Pain you can pinpoint with one finger just below the kneecap
- Pain that appears at the start of activity, sometimes eases during a warm up, then returns afterward
- Stiffness and soreness the morning after a hard session
- Discomfort with jumping, decelerating, squatting, lunging and stairs
- Tenderness when you press the tendon with the knee straight
If the pain is spread across the whole front of the knee, worse with prolonged sitting, or accompanied by swelling inside the joint, it may be patellofemoral pain or a joint issue instead. That is worth confirming rather than guessing.
Why It Develops
- A sudden jump in training volume, intensity or jumping frequency
- Weak or fatigued quadriceps and glutes that leave the tendon absorbing more load
- Limited ankle dorsiflexion or hip mobility that changes landing mechanics
- Hard surfaces and worn footwear
- Returning to sport before an earlier episode was fully rehabilitated
Treatment for Patellar Tendinitis
Physiotherapy and loading
The core of treatment is a progressive loading program, and it works. Our physiotherapy in Mississauga plan for jumper’s knee generally moves through four stages.
- Settle the tendon: reduce the aggravating jumping and deep knee loading for a short window, without going to complete rest, and use isometric holds such as a wall sit or Spanish squat to reduce pain
- Build strength: heavy slow resistance work through leg press, squats and decline squats, loaded gradually across several weeks
- Add speed and power: hops, skips and controlled plyometrics once strength tolerates it
- Return to sport: reintroduce jumping and cutting volume in planned steps, monitoring next morning soreness as your guide
Alongside loading we address hip and ankle mobility, landing mechanics and training load so the tendon is not overwhelmed again. Recovery for a well established tendinopathy typically takes eight to twelve weeks, and sometimes longer for athletes in season. It is slower than people expect, which is exactly why a structured program beats guesswork.
Massage therapy for the patellar tendon
Registered massage therapy is a useful support for this condition. Treatment focuses on the quadriceps, IT band region and calf, since tension in those muscles increases the pull on the tendon. Therapists may use deep tissue work, myofascial release and cross friction techniques around the tendon, followed by assisted stretching. Patients often report the knee feels less tight and tolerates exercise better afterward. Massage is a complement to loading, not a replacement for it.
Chiropractic care and adjunct treatments
Chiropractic care can help restore movement in the hip, ankle and low back so the leg distributes load properly. For tendons that stay stubborn after a solid loading program, shockwave therapy is a reasonable next step, and dry needling can help with persistent quadriceps tightness. We also treat these knees as part of our broader sports injury care.
What to Avoid
- Complete rest for weeks. The tendon gets weaker and the pain returns as soon as you resume play.
- Aggressive stretching of a painful tendon, which can increase compression at the kneecap.
- Repeated cortisone injections into the tendon, which are associated with poorer long term outcomes.
- Pushing through sharp pain in training and hoping it settles on its own.
Frequently Asked Questions
How long does jumper’s knee take to heal?
A recent, mild case can settle in four to six weeks. A tendinopathy that has been building for months usually needs eight to twelve weeks of consistent loading, and in season athletes often manage symptoms while playing and complete the rebuild in the off season.
Is massage good for patellar tendonitis?
Yes, as a support. Massage to the quadriceps, IT band and calf reduces the tension pulling on the tendon and often makes rehab exercises more comfortable. Combine it with a strengthening program for lasting change rather than relying on massage alone.
Should I keep playing my sport?
Often you can, with adjustments. If your pain stays at a low level during play and settles by the next morning, a modified schedule is usually workable. If pain climbs during activity or lingers into the next day, volume needs to come down while you build strength.
Does jumper’s knee show up on imaging?
Ultrasound or MRI can show tendon changes, but imaging findings do not always match symptoms. Diagnosis is usually made through history and physical assessment, with imaging reserved for unclear cases.
Can I prevent it coming back?
Yes, mostly. Keep quad and glute strength up year round, progress training volume gradually, keep some heavy slow resistance work in your routine, and treat morning stiffness as an early signal to adjust load.
