01A Message From Dr. Pettit

Thank you for the opportunity to take part in your care. Our number one goal, along with our team at Beacon Orthopaedics and Sports Medicine, is to improve your quality of life through our knowledge, skill, experience, and — most importantly — compassionate care. Meniscal Transplant is a highly effective procedure, but we recognize that surgery can be stressful, and we hope to make this process as smooth as possible.

This guide is a resource to help you and your loved ones understand your meniscal transplant, prepare for the day of surgery, and know what to expect during your recovery. Please keep it with you up to your date of surgery and beyond. Our team is always here to answer your questions — please do not hesitate to contact us about anything.

Sincerely,
Robert J. Pettit, MD

02About Your Meniscal Transplant

Procedure Illustration

Knee anatomy · for education; your anatomy may differ

For a younger patient who has lost most of the meniscus and has pain in that compartment (but not yet significant arthritis), a meniscal allograft transplant replaces the missing meniscus with donor tissue to restore cushioning and protect the cartilage.

Meniscal allograft transplantation replaces a missing or severely damaged meniscus with donor (allograft) tissue, sized to match your anatomy, restoring cushioning and load distribution in a knee that has lost most or all of its native meniscus.

03Is This the Right Procedure for You?

Why it may be recommended

Significant meniscus loss from prior surgery, most often in younger patients
Persistent pain in the affected compartment without significant arthritis
Desire to preserve the joint and delay or avoid arthritis progression

What it is intended to achieve

Restores cushioning function lost after extensive meniscus removal
Can meaningfully reduce pain related to meniscus deficiency
May help protect cartilage and delay further joint degeneration

04Risks to Understand

Risks include infection, stiffness, graft tearing or shrinkage, incomplete symptom relief, and the possibility of needing further surgery. Dr. Pettit will discuss whether your knee is a good candidate based on alignment and cartilage health.

05In the Weeks Before Surgery

Complete your pre-operative clearance. Depending on your age and health, you may need lab work, an EKG, or a visit with your primary care doctor or cardiologist. Our surgery scheduler will tell you exactly what is required
Review your medications with us. Blood thinners (such as warfarin, Eliquis, Xarelto, Plavix, or aspirin) and certain supplements may need to be stopped before surgery
but never stop a prescribed medication without instruction from the prescribing doctor
Stop nicotine. Smoking and vaping slow healing. Stopping even a few weeks before surgery improves your recovery
this is especially important for tendon, ligament, cartilage, and bone healing
Arrange a ride and a helper. You cannot drive yourself home after anesthesia. Plan for a responsible adult to drive you and to stay with you the first night
Prepare your home. Set up a comfortable recovery area with everything within reach, clear tripping hazards and loose rugs, and stock easy meals. If you will use crutches, a walker, a sling, or a brace, practice with it ahead of time
Fill prescriptions early. If Dr. Pettit sends pain medication or other prescriptions before surgery, fill them ahead of time so they are ready when you get home.
Complete pre-operative clearance, labs, and imaging for graft sizing
Stop NSAIDs and blood thinners as directed
Arrange help at home for the first couple of weeks
Follow fasting instructions before surgery

06The Day of Surgery

Sandy Evans, our surgery scheduler, will give you your exact arrival time and location, and will tell you when to stop eating and drinking — generally nothing to eat or drink after midnight the night before, unless you are told otherwise. Take only the medications we tell you to take, with a small sip of water. Leave jewelry and valuables at home, wear loose, comfortable clothing, and bring your photo ID, insurance card, and this guide. Most of our procedures are outpatient, meaning you go home the same day. You will meet the anesthesia team before your procedure to review your anesthesia plan and answer any questions.

07What to Expect After Surgery

You will go home in a brace and on crutches, with weight-bearing and bending restricted early to protect the transplant
Rehabilitation is deliberate and gradual, similar to a meniscus repair, to allow the graft to heal and integrate
Return to higher-impact activity is typically several months and is individualized
Follow strict protected weight-bearing instructions
Use your brace exactly as directed
Elevate and ice the knee regularly
Begin physical therapy per your protocol once cleared

Recovery timeline

Weeks 0–6: limited weight-bearing and motion
Months 2–4: progressive weight-bearing and strengthening
Months 4–9: gradual return to low-impact activity
High-impact and pivoting sport is approached cautiously and individually

Your detailed, week-by-week recovery instructions come in your post-op protocol, which Dr. Pettit and our team will review with you and provide in print and online at robertpettitmd.com/protocols/meniscal-transplant.pdf

08Post-Op Quick Reference

Keep this section for after your surgery. These highlights are drawn from Dr. Pettit's Meniscal Allograft Transplantation post-operative protocol — your procedure may use a different variant, so always follow the copy you receive at surgery.

Medication management

You have been given a regional anesthetic block prior to your operation; this will wear off in the evening following your surgery. We recommend taking pain medication once you feel the block wearing off. You may find it beneficial to sleep in a recliner or propped up with pillows in the days following surgery.

Pain Medication: Tylenol 1000mg every 8 hours and, unless discussed otherwise, you have been prescribed a narcotic pain medication (Oxycodone 5mg) to take every 4-6 hours as needed.

DO NOT drive/use any heavy machinery, drink alcohol, make any life-changing or legal decisions (i.e. sign a will), or participate in activities that require a lot of physical skill, as narcotics may change your mental acuity. On rare occasions they may cause confusion or disorientation, we advise you to discontinue this medication should that occur.
Narcotics can be addictive. Dispose of any excess medication at a police/fire station.
Take a stool softener (e.g. Colace) while taking narcotic medication, as narcotics may cause constipation. If this does not help alleviate your constipation, you can try adding miralax or milk of magnesia. Please call our office if this regimen does not alleviate your constipation.
If you have any questions or concerns about narcotic strength medications, please contact us.

Anti-nausea: Zofran (Ondansetron): Take as prescribed if needed for nausea

Anti-Inflammatory: Unless contraindicated due to other health reasons, you have been prescribed a non-steroidal anti-inflammatory drug (Ibuprofen 800mg) for use postoperatively. If you have no personal history of adverse response to anti-inflammatories (NSAIDs), take as prescribed: Ibuprofen every 8 hours with food to help reduce swelling and pain. Do not take other NSAIDs (Celebrex, Advil, Aleve, etc) with Ibuprofen.

Muscle relaxer: Flexeril (Cyclobenzaprine) for muscle spasms. Take this as needed, it will make you drowsy.

Antibiotic: You will be given a prescription antibiotic, IF you do not stay overnight in the hospital, as a precaution for 7 days. Take twice a day with food.

Tylenol and Celebrex/Ibuprofen are the foundation for your pain control regimen. Example dosing: 1000mg Tylenol then 4 hours later 800mg Ibuprofen then 4 hours later repeat — every 4 hours alternate between Tylenol and Ibuprofen. Oxycodone as needed for breakthrough pain. *You should not exceed 3,000mg of Tylenol or 3,200mg of Ibuprofen in 24 hours.

Crutches & Weight Bearing Status

Following a Meniscal Transplant, you will use crutches for the first 6 weeks. You will be non-weight-bearing to heel-touch, with your hinged brace locked in extension for walking
Starting around week 6, we will ease you back toward full weight bearing in stages, reaching full weight bearing by weeks 8–9
The brace is typically discontinued between weeks 8 and 12, once you can walk without a limp

Follow-up appointment

Your first post-operative appointment will be scheduled 10 – 14 days following your surgical procedure. Typically dissolvable sutures are used during surgery, and do not need to be removed. If you do not have a post-operative appointment scheduled when you leave following surgery, please call 513-441-5639 to make the appointment. ***

*Signs & Symptoms to Immediately Report*
Call 911 and go to the nearest hospital if you are having chest pain or trouble breathing.
Call the office at 513-354-3700 to report any of the following:

Persistent fever (101 or greater)
Sudden increase in pain and swelling
Wound redness or drainage (besides blood)
Increased skin temperature around incision
Deep calf pain and swelling
Severe abdominal pain

Your home exercise program. Dr. Pettit will guide you through a staged exercise programme after surgery. The full Knee Home Exercise Program, with photographs and dosages for every exercise, is available at robertpettitmd.com/exercise-programs/knee.pdf — follow the specific instructions you are given at your visits.

09Common Questions

Who is a good candidate for a meniscal transplant?

Generally younger, active patients with significant meniscus loss and relatively healthy cartilage in the affected compartment.

Will this restore my knee to normal?

It can meaningfully reduce pain and improve function, though it's intended to relieve symptoms and protect the joint rather than fully recreate the original meniscus.
