Most people who end up in surgery for their knee did not have to get there that quickly.
That is not a controversial statement among physios who work with knees daily. It is, however, a statement that tends to get buried beneath the urgency of an orthopaedic referral, the anxiety of an MRI report, and the quiet authority of a specialist who has a theatre slot available.
At Instinct South we work with people before, around, and after surgery, and one pattern appears more consistently than any other. The clients who do best are the ones who treated physiotherapy as a serious intervention.
Your Knee Condition Matters More Than You Think
Treating knee pain with the same approach can sometimes lead to poor outcomes.
Take two common presentations we see regularly.
The first is a 58-year-old former runner with medial compartment osteoarthritis, grade 3 changes on X-ray, morning stiffness that eases within 20 minutes, and pain that flares after going up two flights of stairs.
The second is a 32-year-old desk worker with anterior knee pain, a feeling of grinding under the kneecap when squatting, and a history of sitting for long hours with the knee bent past 90 degrees. Same complaint yet entirely different problems and entirely different programmes.
Patellofemoral pain syndrome, where the kneecap tracks laterally during knee flexion and loads the lateral facet unevenly, responds well to quad strengthening in a specific range, hip abductor and external rotator work, and sometimes patellar taping to buy pain-free movement while the muscle work takes effect.
Loading through a deep squat early in this process is counterproductive, because it is exactly the range where the compressive force on the already irritated facet is highest. A generic “knee strengthening” programme that includes full-depth squats from week one will make this person worse.
The approach for that 58-year-old works on a different principle entirely.
The medial compartment is the inner side of the knee joint, and in this type of arthritis it takes more force than it should with every step. The goal is to reduce that force through a few different routes.
First, strengthening the VMO (the teardrop-shaped muscle just above and to the inside of the kneecap) helps the joint absorb load more evenly.
Second, retraining the way someone walks can reduce how much the knee pulls inward during each stride, which is one of the main reasons that the inner compartment gets overloaded in the first place.
Third, any strengthening work needs to be introduced gradually enough that the joint does not react badly for the next 48 hours. If someone is wiped out for two days after every session, the load is too high and the joint is telling you so.
In some cases, a small wedge insert placed on the outer edge of the shoe sole is enough to shift how force travels through the knee, and people often notice a real difference in pain within just a few days of wearing it.
The point is that a diagnosis of “knee pain” is the beginning of clinical thinking.
The Myth of “Bone on Bone”
This phrase causes enormous unnecessary anxiety and deserves to be addressed directly.
When a client comes in having been told their knee is “bone on bone,” they often arrive believing that every step they take is grinding two raw surfaces against each other and that surgery is the only logical rescue. But joint space narrowing on X-ray, even significant narrowing, does not reliably predict pain severity, function, or how a person will respond to rehabilitation.
A large pooled analysis found that roughly 40% of middle-aged and older adults with clear signs of knee arthritis on X-ray had no pain at all. The reverse is equally common, a significant daily pain with scans that look relatively unremarkable. What imaging shows and what a person feels do not line up as reliably as most people assume.
A 2013 New England Journal of Medicine study drove this point home. Patients with degenerative meniscal tears were split into two groups: one had real arthroscopic surgery, the other had a procedure that mimicked surgery without any actual work being done inside the joint. Both groups improved by roughly the same amount. The tear was real. The surgery was real. It just did not help.
This does not mean imaging is useless. But the majority of what we see on scans in people aged 45 and over reflects the accumulated load history of a joint.
