When to See a Physiotherapist
Book an assessment if your knee pain is affecting your training week after week, if you’re unsure how to dose your loading exercises, if pain is worsening rather than settling, or if you simply want a clear, staged plan rather than guessing. A physiotherapist can also rule out other causes of anterior knee pain that need a different approach.
Patellar Tendinopathy: Should You Rest or Keep Training?
Patient story is a fictional example created for educational purposes, based on common physiotherapy scenarios.
Sarah had been running three times a week for two years when a dull ache under her kneecap started showing up on longer runs. A friend told her to “just rest it for a few weeks.” She did. The pain eased, then came straight back the moment she laced up her trainers again. Six weeks of sitting on the sofa hadn’t fixed anything. It had just made her tendon weaker and her confidence lower.
Sarah’s story is one of the most common we hear at Physora Physio in Neath. And it points to one of the biggest misunderstandings in tendon injuries: rest doesn’t rehabilitate a tendon the right kind of load does.
What Is Patellar Tendinopathy?
Patellar tendinopathy, often called “jumper’s knee,” is an overload injury of the tendon connecting the kneecap to the shin bone. It’s especially common in runners, and in jumping and cutting sports like basketball, volleyball, and netball, where the tendon repeatedly absorbs and releases high forces.
Rather than a simple “inflammation,” current understanding describes tendinopathy as sitting on a continuum: from a reactive tendon that’s temporarily overloaded, through to more persistent dysrepair and, in longstanding cases, degenerative changes in the tendon structure. Where someone sits on that continuum affects how aggressively they can load the tendon early on, but at every stage, some form of loading remains part of the solution, not the enemy.
Why “Just Rest It” Usually Doesn’t Work
It’s a natural instinct: something hurts, so you stop using it. But tendons adapt to load they don’t recover well from the absence of it. Complete rest can temporarily settle pain, but it doesn’t rebuild the tendon’s capacity to tolerate the running, jumping, or squatting that caused the problem in the first place. When training resumes, the tendon is often less prepared than before, and symptoms frequently return quickly, as they did for Sarah.
This is why current guidance for patellar tendinopathy favours relative load management, adjusting how much and what kind of load you’re doing rather than stopping completely.
What the Evidence Actually Recommends
A staged, progressive loading approach, as described by Malliaras, Cook, Purdam, and Rio (2015), is widely used in current practice. It generally moves through four stages:
Stage 1 — Isometric Holds. Static, non-moving contractions (such as a held wall sit or static leg press) are often introduced first. Research by Rio and colleagues (2015) found that short bouts of isometric contractions produced an immediate pain-relieving effect for patients with patellar tendinopathy, which can make subsequent exercises more tolerable. It’s worth noting this effect isn’t universal later studies in other tendons found a more mixed, individual response — so isometrics are best viewed as one useful early tool rather than a guaranteed pain switch.
Stage 2 — Isotonic (Strengthening) Loading. Slow, controlled strengthening exercises, squats, leg press, and split squats build the tendon and muscle’s capacity to tolerate load. Evidence comparing eccentric-only training to combined concentric/eccentric (“heavy slow resistance”) work has not shown a clear winner; a clinical review concluded there is no convincing evidence that isolated eccentric loading produces better outcomes than other loading approaches, so your physiotherapist has flexibility in choosing the method that suits you.
Stage 3 — Energy Storage / Plyometric Loading. Once strength improves, controlled jumping, hopping, and change-of-direction drills are reintroduced gradually — progressing from double-leg to single-leg work over several weeks, with lower-intensity exercises maintained on non-plyometric days.
Stage 4 — Return to Sport. Sport-specific training is layered back in, with maintenance strengthening continued at least twice weekly even after return to sport, since stopping strength work altogether is a common cause of relapse.
At Physora Physio, this progression is built into every structured, assessment-led rehab plan, adjusted to your sport, training load, and how irritable your tendon currently is.
How Much Pain Is OK During Training?
This is the question we’re asked most. Historically, patients were told to avoid pain entirely, but a small amount of pain during loading exercises is now generally considered acceptable, provided it settles within 24 hours and isn’t progressively worsening session to session. A 2024 randomised crossover study found no difference in pain intensity between lighter and heavier training loads in people with patellar tendinopathy, suggesting higher loads can often be applied without necessarily increasing pain. In practice, this means your physiotherapist may not automatically reduce your load just because you report some discomfort. The trend of your symptoms over days matters more than the sensation in any single set.
Realistic Recovery Timeframes
Patellar tendinopathy is rarely a quick fix, and being told otherwise sets patients up for frustration. Systematic evidence on loading-based rehabilitation suggests roughly a 50–70% likelihood of meaningful improvement at three to six months. This is a marathon of consistent, well-dosed loading, not a two-week fix. Persistent cases that don’t respond to structured exercise over this timeframe may be considered for other conservative or medical options, ideally guided by a clinician who can also assess whether your training load, footwear, surfaces, or biomechanics are contributing factors.
Preventing Patellar Tendinopathy From Returning
Progress training load gradually avoid sudden spikes in running distance, jump volume or squat weight
Keep a consistent, ongoing strengthening routine even once symptoms settle
Address deficits elsewhere in the kinetic chain (hip and calf strength are commonly under-conditioned)
Manage overall training volume across all your sports and gym sessions, not just one activity in isolation
FAQs
Do I need a scan to diagnose patellar tendinopathy?
Usually not. It’s typically diagnosed clinically, based on your history and specific tests such as tenderness at the lower pole of the kneecap and pain with loaded knee extension. Imaging is sometimes used in complex or non-responding cases.
Can I keep running or playing sports while I rehab?
Often, yes, in a modified form, this is decided based on your irritability level and how your symptoms behave over 24–48 hours, not a blanket rule.
Is eccentric exercise essential?
Not necessarily. Current evidence doesn’t clearly favour eccentric-only training over combined strengthening approaches, so your programme can be tailored to what you’ll actually stick to.
Will it come back?
It can, particularly if strengthening work is dropped once pain settles, ongoing maintenance loading is one of the best-supported ways to reduce recurrence.
Ready for a Clear Plan Instead of Guesswork?
If patellar tendon pain is holding back your running, gym sessions, or sport, our team at Physora Physio in Neath can assess your tendon, your training load, and your movement patterns, then build a staged loading plan around your goals as part of our wider sports injury rehabilitation service.
