Knee Pain in Sydney's Eastern Suburbs: Causes, Treatment & When to See a Physio

Knee pain is one of the most common musculoskeletal complaints we see across Sydney's Eastern Suburbs, from Bondi Beach runners to desk workers in Surry Hills who've developed pain just from climbing stairs. The knee is a complex joint, and what feels like the same problem can have very different causes depending on where the pain is, when it comes on, and what makes it better or worse.

Where it hurts: a location guide

The location of your pain is one of the most useful clues. A thorough assessment is always needed for diagnosis, but knowing what structures live where gives you a framework for understanding what might be going on.

Front of the knee

Pain at the front of the knee is the most common presentation. At the bottom edge of the kneecap, it's usually patellar tendinopathy, worse with jumping and squatting. Diffuse pain across the kneecap, especially on stairs, hills, and after sitting, often points to patellofemoral pain syndrome (runner's knee), a problem with how the kneecap tracks rather than structural damage, and very common in runners and cyclists. Pain just below the kneecap in adolescents is commonly Osgood-Schlatter disease.

Inside of the knee

Inner knee pain is usually one of three things: a medial collateral ligament (MCL) sprain, typically from a force that pushes the knee inwards; medial meniscus pathology, which often presents with joint line tenderness and clicking; or pes anserine bursitis, more common in older patients and runners, sitting about 3-4cm below the joint line.

Outside of the knee

Outer knee pain in runners is most often iliotibial band syndrome, which classically comes on at a predictable distance into a run and eases when stopping. Lateral meniscus tears cause joint line tenderness and pain with loading. Lateral collateral ligament injuries are less common but occur in contact sport.

Back of the knee

Pain behind the knee often comes from a Baker's cyst, a fluid-filled sac that is usually secondary to a problem inside the joint such as a meniscus tear or osteoarthritis. Hamstring tendon pain at the attachment behind the knee is also possible. Posterior cruciate ligament involvement is rare outside of significant trauma.

Deep in the joint

Deep, diffuse pain with swelling is more likely to come from inside the joint: the ACL, a meniscus, or the joint cartilage. Sharp pain with twisting, locking, or giving way suggests a meniscus or ligament injury, and any significant swelling after a twisting or pivoting injury should be assessed promptly. Gradual-onset deep pain that is worse in the morning and eases with gentle movement is more typical of osteoarthritis.

When to see a physiotherapist

You should book an assessment if your knee pain has lasted more than a week without improvement, if it's limiting your ability to exercise or do daily activities, if you have swelling, or if your knee gives way or locks. Early treatment almost always produces better outcomes, because the longer a knee problem is left, the more compensatory movement patterns develop and the more complicated the rehab becomes.

What physiotherapy treatment involves

A thorough knee assessment starts with understanding your history: how long the pain has been there, what aggravates it, and what activities you need to get back to. This is followed by a physical assessment of the joint itself, the surrounding muscles (particularly hip abductors and quadriceps), and your movement patterns. Most knee conditions respond well to a combination of load management, targeted strengthening, manual therapy, and gradual return to activity.

Mobile physio for knee pain in the Eastern Suburbs

One of the advantages of mobile physiotherapy is that Seth can assess you in the environment where you spend most of your time, your home. He can observe how you move around your space, identify any environmental factors contributing to your problem, and begin treatment in the same session. No travel required, particularly useful if your knee is painful enough to make getting around difficult.
