Most people expect joint pain to follow a predictable arc — injury, treatment, recovery. What's less discussed is how often the arc stalls.
A 2021 review in the Journal of Orthopaedic Surgery and Research found roughly 20% of patients report chronic pain following knee replacement, one of the most performed procedures in orthopedics. For rotator cuff repairs, that figure runs higher. These aren't failed surgeries, at least not structurally. Imaging often shows solid healing. The pain just didn't read the memo.
Why pain sometimes outlasts the injury
Orthopedic imaging is full of surprises in both directions. It routinely turns up meniscal tears, labral fraying, and disc bulges in people with zero pain. It also shows normal-looking tissue in people who are miserable. The relationship between structural damage and what you actually feel is messier than most patients realize.
After a prolonged injury or surgery, the central nervous system can shift into a state researchers call central sensitization. The pain system starts amplifying signals that would normally be unremarkable — light pressure becomes sharp, routine movement becomes a provocation. The tissue may be healed. The alarm keeps firing anyway.
This kind of pain has a neurological basis. It responds differently to treatment than the mechanical pain that caused the injury in the first place, and many patients — and some clinicians — don't realize the problem has changed character.
When standard care stops moving things forward
Anti-inflammatories and physical therapy work for most patients. When central sensitization is involved, treating inflammation alone is a partial solution at best.
Cortisone injections can quiet joint inflammation for weeks, but repeated use carries risk: cartilage damage, diminishing returns. PRP and hyaluronic acid have expanding evidence, though outcomes vary enough that they're not a reliable answer for everyone.
Surgery can still be the right call when there's a clear structural problem — a loose body in the knee, a full-thickness rotator cuff tear, advanced arthritis that's destroyed cartilage. The harder judgment call is when the structural findings are equivocal and the patient has already been in pain for months. Operating on a nervous system in a sensitized state can sometimes worsen outcomes. Surgeons increasingly flag this as a risk factor in pre-operative planning.
What a broader approach looks like
For persistent pain that hasn't responded to standard care, single-treatment approaches tend to underperform. The better evidence sits with multidisciplinary programs that address the physical, neurological, and psychological dimensions together.
Cognitive behavioral therapy has one of the strongest non-pharmacological evidence bases for chronic pain — it targets the fear-avoidance patterns and catastrophizing that amplify pain signals and stall recovery. This isn't about convincing patients the pain is psychological. It's about addressing a real feedback loop.
Graded exercise therapy works by gradually reintroducing movement in a controlled way, avoiding the flares that reinforce avoidance behavior. Done properly, under supervision, it desensitizes the nervous system over time. Done wrong, it backfires.
Acupuncture has a more contested reputation, but the evidence base for musculoskeletal pain has strengthened. A 2012 meta-analysis in Archives of Internal Medicine — drawing on data from nearly 18,000 patients — found acupuncture significantly outperformed both sham acupuncture and usual care for chronic pain. The mechanism likely involves modulation of pain signaling at both peripheral and central levels, which is why it comes up specifically in sensitization cases. Some patients use it as a complement to ongoing orthopedic care through providers offering structured acupuncture protocols.
What to actually say to your surgeon
Three months of persistent pain after treatment and little improvement is a reasonable threshold for a direct conversation. Tell your surgeon what hasn't worked and for how long. Document your patterns — worse in the morning, triggered by specific movements, affecting sleep. That specificity helps distinguish pain that still has a mechanical fix from pain that has shifted into something the OR can't address.
Many orthopedic practices now have referral pathways to pain medicine, physical medicine and rehabilitation, or integrative health providers. If yours doesn't raise it, ask.
