Bad Knee, Severe X-Ray. Why Surgery Isn't Always the First Step

If your knee has been hurting for a while now, chances are you've already heard the standard story: it's wear and tear, it'll only get worse, and eventually you'll need an operation. It's a narrative that's repeated so often it sticks, even though current clinical guidelines for knee osteoarthritis generally recommend starting with conservative treatment before considering more invasive options. A lot of patients still walk away assuming there's nothing to do but wait for things to get bad enough for surgery.

We've been treating knee osteoarthritis for over 45 years, across more than 50,000 patients, and the picture is a bit more useful than that. Here's what's actually happening in the joint, why that narrative misses part of it, and what tends to work instead.

What's actually happening when your knee hurts

The cartilage cushioning your knee joint thins over time. That part is accurate. But "wear and tear" makes it sound like a tyre going bald: a one-way mechanical process that just runs its course. What that framing leaves out is everything else going on around it.

As cartilage and other tissues in the knee change over time, inflammatory processes inside the joint can become more active. In some patients this contributes to the swelling, warmth and stiffness that come with flare-ups, and may also play a role in further joint changes over time. This is one reason symptoms can ease off and flare up in cycles rather than worsening in a straight line, though OA pain is shaped by several factors together, not inflammation alone.

Muscle strength plays into the same picture from a different angle. Every step, every time you stand up from a chair, the muscles around the knee absorb part of the mechanical load before it reaches the joint. When those muscles weaken from reduced use, more of that load lands directly on the joint, which may contribute to ongoing symptoms and altered loading patterns. This is why the knee on its own is rarely the whole story.

Madam Irene's case showed several of these pieces at once. At 66, her knee pain started small, just an ache after standing up off the floor. Later it got worse and she was diagnosed with Grade 3 osteoarthritis. She was given anti-inflammatories, did some physiotherapy but the pain lingered and got worse. Her knee was visibly swollen and larger than the other side and she was walking bent over with a cane when she came to see us.

We treated the swelling and inflammation with our proprietary herbal patches, whose anti-inflammatory properties have been studied. This was supported by infrared heat and ultrasound to support comfort and movement, and later, strengthening exercises for the muscles around the knee. In her words: "Before the treatment, I couldn't walk due to the pain. After the treatment, I can walk very well without any pain."

Why a "severe" X-ray and a painful knee don't always match

Pain often does not correlate perfectly with what appears on an X-ray. Inflammation inside the joint is one factor that can influence symptoms, alongside structural changes, muscle strength, movement patterns and other factors. An X-ray shows structural changes, but it doesn't fully capture inflammation, muscle function, movement patterns or other factors that influence symptoms.

Another patient of ours, Madam Annie, was recommended a knee replacement by her doctor after seeing her scan and hearing she couldn't bend her knee past 90 degrees, with pain she rated 6 out of 10. Concerned about the risks of surgery, she chose to try conservative treatment first. After 21 sessions, her pain dropped to around 2 out of 10 and her knee bent well past the 90-degree mark it had been stuck at.

Current clinical guidelines for knee osteoarthritis recommend exactly this sequence: conservative, multidisciplinary care first, with injections and surgery considered if that doesn't work. Madam Annie's case followed the guideline, not a workaround of it.

What the research says about surgery

Two types of knee surgery come up most often in the context of osteoarthritis, and the evidence on each tells a different story.

Keyhole surgery, where surgeons wash out the joint or trim damaged tissue, has been tested in two large randomized controlled trials published in the New England Journal of Medicine. One compared arthroscopic débridement and lavage against placebo surgery, where patients received the same incisions but no actual procedure. The other compared arthroscopic surgery plus physical and medical therapy against the same therapy without surgery. In both trials, the surgical group did no better than the comparison group. Major orthopaedic guideline bodies have since moved away from recommending routine arthroscopic debridement for knee OA as a result.

Knee replacement is a different matter. A randomized trial, also published in the New England Journal of Medicine, compared total knee replacement followed by structured rehabilitation against structured rehabilitation alone, in patients who were eligible for surgery. At 12 months, the replacement group showed greater improvement in pain, symptoms, daily activities and quality of life. But the surgical group also had significantly more serious adverse events: 24 versus 6 in the nonsurgical group. The trial demonstrated that knee replacement is more efficacious than nonsurgical treatment alone for eligible patients, but that the benefit comes with a meaningfully higher risk of serious complications.

The common thread across both procedures is that surgery is not the starting point the evidence supports. It is the option the evidence points to when structured, multidisciplinary conservative care has run its course.

Managing symptoms instead of waiting it out

Pain and progression in knee osteoarthritis are shaped by a combination of inflammation, joint load and muscle strength, so treatment that addresses several of these factors together, rather than just dulling the pain, tends to give patients more to work with.

Puan Rosni had lived with bilateral knee osteoarthritis for five years, managed mainly with painkillers from her doctor. Painkillers can help manage symptoms, but for many patients they work best alongside exercise, activity modification and other supportive treatment, and over those years she gradually lost the ability to stand or walk for long. Two weeks into a different approach, combining physiotherapy, structured strengthening exercises and our clinic's traditional herbal approach, she regained enough function to stand and walk for longer periods again.

The goal of this kind of approach is to reduce symptoms, improve movement and help patients stay active for longer before considering more invasive options.

Our clinic's herbal approach has been used in our clinics for decades. Its anti-inflammatory properties have been studied through laboratory research conducted by our research partner, Relivium Sciences (maker of PainFix products), with Monash University.
