Treatment for Lyme Arthritis: When Symptoms Persist After Knee Replacement
KNEE SWELLING AFTER SURGERY—BUT NO CLEAR CAUSE?
LYME ARTHRITIS MAY BE MISSED EVEN AFTER REPLACEMENT
A patient undergoes knee replacement surgery—but months later, the swelling returns.
Imaging looks normal. There is no clear mechanical failure. Yet the joint remains inflamed.
What if the cause is not the surgery—but an infection that was never recognized?
Quick Answer: Treatment for Lyme arthritis typically involves antibiotic therapy and may resolve joint inflammation—even in patients with prosthetic joints—potentially avoiding additional surgery.
Clinical Insight: Persistent joint swelling after orthopedic procedures is not always mechanical. In endemic areas, Lyme disease should remain on the differential diagnosis.
Joint swelling is one of many patterns described in the Lyme disease symptoms guide, where musculoskeletal and neurologic symptoms often overlap.
These presentations may also reflect broader persistent Lyme disease mechanisms, including ongoing infection and immune activation.
Can Lyme Arthritis Be Missed After Knee Replacement?
Yes. In some cases, persistent joint swelling after surgery is not due to mechanical complications but to an untreated infection such as Lyme disease.
In the case described by Wright and colleagues, a 67-year-old man developed progressive knee swelling months after a partial knee replacement.
There was:
- No history of tick bite
- No erythema migrans rash
- No imaging evidence of infection or structural failure
This pattern can delay diagnosis.
Diagnosis of Lyme Arthritis in a Prosthetic Joint
Joint aspiration revealed:
- Purulent fluid with high neutrophils
- Elevated inflammatory markers
- Positive PCR for Borrelia burgdorferi
Serologic testing confirmed Lyme disease, meeting criteria for periprosthetic joint infection.
Despite the absence of classic signs, laboratory findings identified the cause.
Why Standard Lyme Arthritis Guidelines Did Not Apply
Typical Lyme arthritis treatment recommendations include:
- 28 days of oral antibiotics
- 14–28 days of intravenous ceftriaxone for more severe cases
However, this case involved a prosthetic joint—requiring a more aggressive approach.
This highlights an important point: treatment for Lyme arthritis must be individualized.
Treatment for Lyme Arthritis With Antibiotics
The patient was initially treated with oral doxycycline while awaiting confirmation.
After diagnosis, therapy was escalated to a six-week course of intravenous ceftriaxone.
The outcome included:
- Resolution of knee pain
- Disappearance of joint effusion
- Normalization of inflammatory markers
- Negative follow-up PCR testing
No additional surgery was required.
This case demonstrates that appropriate treatment for Lyme arthritis may prevent invasive procedures.

Periprosthetic Joint Infection Risk
Periprosthetic joint infections are serious complications, occurring in approximately 1%–2% of joint replacements.
They are typically associated with significant morbidity and often require surgical intervention.
Identifying a treatable cause such as Lyme disease can change this trajectory.
Why Lyme Arthritis Gets Missed
Lyme arthritis may be overlooked because:
- Tick bites are often not recalled
- Rashes may be absent or missed
- Symptoms overlap with common orthopedic conditions
This reflects a broader issue in Lyme disease care—diagnostic complexity.
When symptoms persist without a clear explanation, Lyme disease should be reconsidered.
Clinical Takeaway
Treatment for Lyme arthritis can resolve persistent joint inflammation—even after knee replacement surgery.
When swelling persists and standard explanations fall short, clinicians should consider Lyme disease as a potential cause.
Early recognition may prevent unnecessary surgery and lead to recovery with antibiotic therapy alone.
Frequently Asked Questions
Can Lyme arthritis occur after knee replacement?
Yes. It may mimic mechanical or postoperative complications.
Does treatment for Lyme arthritis always require surgery?
No. Antibiotic therapy alone may be effective.
Can Lyme arthritis be diagnosed without a tick bite?
Yes. Many patients do not recall a tick exposure.

My son has chronic lyme disease. He has it in his left knee. We have tried antibiotics, biofilm busters, oxidative therapies Iv antibiotics( only once)
Any suggestions we live in Maine

Dr Cameron, I contracted Lyme Disease in 1989 and have been treated and manage my Chronic Lyme Disease. I had a knee replacement 4 years ago and I need another as soon as I can solve this problem. In January my knee replacement knee became inflamed and after careful evaluation for loose parts and bakers cyst, no reason could be found. I am anxious about getting another knee replacement and have the same problem, so I am trying to find out more. My primary care is Dr. Daniel Peterson of Incline Village Nevada, I am also part of studies at Columbia with Dr. Brian Falon. I would like to arrange to have the fluid remove from the knee replacement to see if the bacteria could be cultured. Where could I send the sample. I live in Santa Rosa, California. I would be able to travel to get this done. Thank you, Barbara McKenna, age 69. st****@***il.com

New York has supported cultures. We are not clear on where to sent the fluid.
I acquired a patient who had total knee arthroplasty after delayed treatment for EM rash just 2 months earlier. previous to this he had Lyme diagnosed in past with IDSA treatment. I believe at time of surgery for knee he was not treated adequately for his very recent and remote infections, then underwent the surgery. I met him a year later when informed he had to retire early due to persistent pain in the knee and has declined since, with multi system symptoms. Tried oral combinations then Bicillin with no benefit. Not clear if persistent infection, biofilm, immune activation. Is there value in IV Ceftriaxone at this point? surgery was 2017, met him 2019
Hello,
My name is JoAnne Hopkins. I am a 61 year old female status post bilateral total knee replacements in Jan 2016. Initially the result was very good and the pain was alleviated. However, I was diagnosed about a year later with Lyme disease when I had a spontaneous rupture of my extensor pollicis longus tendon of my left thumb. I never had a rash so my lyme went untreated for quite sometime. I see a lyme specialist regularly since then and have been on and off oral antibiotics for 4 1/2 years. After being off the antibiotics for approximately 6 months (this was about 2 years ago) I developed increased pain in both of my knees. I have since been back on oral antibiotics but feel the damage has been done and the knee pain is getting worse. The orthopedist has taken X rays at least 2 or 3 times since then and he states that there is no orthopedic reason for my increased pain. He states that he could aspirate but as there is no real edema present, he didn’t think it was a good idea due to risk of infection. My Lyme specialist is also not familiar with this. I have asked numerous doctors about the lyme being the cause of this increased pain but none seem to have any experience with it. I recently had lumbar surgery, 4 months ago, for chronic pain due to spondylolysthesis, and am starting to have increased pain again. I an fearing that the Lyme has now invaded that region as well. When I saw this article about the lyme infection post knee surgery I was very excited. I am hoping you may have some suggestions that I could relay to my lyme specialist. Some questions I have are should I proceed with the aspiration? Should I see an infectious disease specialist? I don’t live very far from New York as I reside in west central New Jersey. Thank you for your time. I look forward to hearing from you.
I have patients who have a history of orthopedic surgery or an orthopedic injury who have benefits from antibiotics. It is hard to judge whether additional antibiotics would be helpful.
Dr. Cameron
First thank you for all the information you put out for us with Lymes and co-infections (babesia).
I had arthritis in my feet, surgery was done several screw put in. In the same timeframe surgery on my wrists and elbows.
Two years later the pain in my feet continued to get worse we could see the rejection of hardware and the hardware was removed All but on screw right big toe.
June I had L-4 L-5 laminectomy and fusion. 4 screws, disk and bone graph from hip.
I have continually worried about another rejection, the pain has been extreme in left buttock to toes since the surgery.
Anxiety has been high since surgery
I have written all this and can’t remember my original thought. This happens often. Any thoughts from you on this
Same here, knee replacement 8/19, no problems, tick bite, 4/21, 4 weeks doxycycline, therapy, 2 aspirations now, clear fluids . Thought replacement would help me enjoy grandchildren, but instead dealing with pain, swelling, can’t do flowerbeds, limited activities with children, at 71 I’m not to old to enjoy retirement, instead dealing with pain, swelling, limit Ed activities, depressing…both drs don’t seem to have all the facts on this!
