Knee meniscus tears are one of the most common injuries seen in orthopaedics. The meniscus is a structure that sits in the knee between the femur (thigh bone) and tibia (shin bone) and acts as a shock absorber and secondary stability structure. It has a very limited blood supply which explains why it has limited healing capability. If torn, the meniscus can cause significant pain, swelling, catching/locking symptoms, and giving way symptoms.
Two types of meniscus surgery:
Partial meniscectomy: This is where the part of the meniscus that is torn is removed.
this is where the meniscus is torn in a degenerative way and usually involves the thinnest and central part of the meniscus.
the involved area does not have enough blood supply to heal.
this represents about 90% of all meniscus surgery.
much faster recovery (approimately 4-8 weeks total).
Meniscus repair: This is where the meniscus is stitched back to itself.
requires the meniscus tear to be located at the edge and typically needs very good tissue to work.
typically in young patients.
this represents only about 10% of all meniscus surgery.
much longer recovery (approximately 6 months total).

BEFORE SURGERY: There are many tasks that can help your surgery process go smoothly. They include the following:
Medical clearance: some patients have medical issues that may impact the safety and risk of the surgery. If you have any issues that we are concerned about, we will request that you obtain a “medical clearance” from the appropriate physician’s office. This may be a primary care physician, cardiologist, pulmonologist, neurologist, etc. We will not proceed with surgery unless these clearances are in place…even if they are well controlled on medication.
Prescriptions: you will be prescribed several medications for AFTER surgery but you need to pick them up ahead of time. We will prescribe these to your listed pharmacy approximately 1 week before surgery. Pharmacy and insurance companies have become much harder to work with and we strongly recommend getting these in advance of surgery as there will be times when the medications are difficult to get or require more paperwork than is usually necessary.
Pain medication (typically oxycodone or alternative). This is a narcotic and addictive. Please use as little as possible. You should use it ONLY as needed follow the dosing as prescribed.
Stool softener (colace). This helps prevent constipation while you are on the pain medication. Please take it routinely as long as you are on the pain medication.
Blood thinner (Aspirin). We typically recommend aspirin 325mg daily starting on day 1 after surgery until you are off of crutches. If you have stomach issues or intolerance to this medication, please let us know ahead of time.
Nausea medication (Ondansetron). This helps if you are having nausea from the anesthesia or pain medication. Use it as needed.
Muscle relaxant (cyclobenzaprine). This helps if you are having muscle spasms after surgery or during physical therapy. This can cause you to be sleepy and can help at night if you are having trouble sleeping. Use it as needed
Arrange physical therapy. We would like physical therapy to start about 1 week after surgery. This can be done near your home. We have physical therapy in our office two locations for you, if convenient. The referral will be placed but it is still up to you to schedule. Please arrange prior to surgery.
Obtain crutches: you will start with a crutches immediately after surgery for weight bearing. Typically, we will instruct you to be 30% partial weight-bearing for about 1 week after surgery. If you are not stable with crutches, then consider a walker.
Get waterproof dressings ahead of time. If you wish to purchase either one of these waterproof dressings seen our video below, click on the picture and it will take you to Amazon.

Food prep: Because your mobility will be less after surgery, we recommend preparing some meals ahead of time and freezing them so that you can simply warm them up when you are recovering. Preparing 1-5 days of meals should get you through the early phase and your mobility will be improved after that time.
Expect a call from the surgery center pre-op nurse who will be reviewing your medical history and medications for your stay. This is part of the pre-anesthesia plan. They will have recommendations regarding any medications that you typically take daily.
Expect a separate call the business day before your surgery from the surgery to communicate your check-in time. This is typically 1-2 hours before the actual surgery time.
For the evening before surgery, have a nice dinner and drink a big glass of water before you go to bed because NOTHING to EAT or DRINK after midnight. If you violate this, the surgery will be cancelled.
DAY OF SURGERY: This is the big day, but relax…all you need to do is show up. The rest is up to us. Please bring the following with you as you will most likely be spending the night recovering.
Insurance card for the surgery center
The surgery will typically be performed at Orthopaedic and Spine Center of Southern Colorado: 4110 Briargate Parkway, Suite 200. This is the second floor of the same building you have been to see me.
Wear loose clothing and bring your crutches!
Family and friends are welcome to come and go as they please and I will update the family as soon as the surgical procedure is finished.
AFTER SURGERY: Congratulations! You have an improved knee. You will want to review the following as it pertains to your knee surgery.
Weight-bearing
If a partial meniscectomy (partial removal of the torn meniscus) is performed, you will be 30% weight-bearing as tolerated typically for about 1 week. That means you can put the weight of the leg itself on the ground for balance with the rest of your weight on your good leg and on your arms with crutches. Here is a video on how to use crutches:
If a meniscus repair (stitches placed in meniscus) is performed, then you will be instructed to be on crutches for 6 weeks total. We will also ask your weight-bearing to be toe-touch weight bearing where you only put the lightest of pressure down on the surgery leg.
Surgery Dressing
This video will show you what to do on the first day after surgery to get the dressings removed:
It is common to see bruising surrounding the incision and the bruising and swelling often will spread down the outer thigh. Do not be concerned as this is expected.
Keep up with your fluids and nutrition.
Start physical therapy. Click here for the physical therapy protocol if you need it.
FREQUENTLY ASKED QUESTIONS:
Will I need crutches after surgery?
Yes. Videos above show crutch usage.
Will I need a knee brace?
No. If a partial meniscectomy (partial removal of the meniscus) is performed, then no brace is required.
Yes. If a meniscus repair (meniscus is stitched together) is performed, then you will need knee brace for 6 weeks.
Can I take my knee brace off?
Yes. You can remove it when you are sitting down. Please put it on when up and moving around.
Please wear the brace at night for sleeping.
Sleeping is difficult…is this common?
Yes, this is common. Many patients find comfort sleeping with a pillow or two under the knee.
How often should I ice my knee?
If using ice packs or bags, we recommend putting ice on for about 20 minutes and then removing the ice pack/bag for 20 minutes and then repeating.
If you have a cold compression device, it can be left on for 30-60 minutes
Audubon Orthotics & Prosthetics has a rental unit that provides both cold therapy and compression. Many patients find this to be very helpful after surgery. Please let us know if you would like to see or rent one and we will connect you with them.
I have the sequential compression devices for my legs (calf squeezers). When and how do I use them?
These devices are designed to help circulate your blood when you are less mobile. Please utilize them when you are sitting for more than an hour and at night if possible when you are sleeping
These devices have a battery, but it does not last long. We typically recommend keeping them plugged in.
When you are up and moving around, they are not needed.
Can you explain my medications again?
We give you a variety of medications to try to make the recovery go smoothly. Remember that most of these medications are AS NEEDED. So, if you do not need them, do not use them.
Pain medication (usually oxycodone or alternative). This is the narcotic. It is to take the edge off of surgical pain. It will not eliminate the pain. These are addictive so please use sparingly.
Stool softener (Colace). While taking the narcotic, please take a stool softener to counteract the constipation caused by the pain medication.
Anti-nausea (ondansetron or phenergan). This is provided if you have nausea after surgery.
Muscle relaxant (cyclobenzaprine or other). This is provided to help with muscle spasms that can occur after surgery. This can be taken with the pain medication or all by itself. Please be aware that it makes most patients sleepy.
Blood thinner (Aspirin). All surgical patients are at risk for blood clots. Based on your personal risk, we will prescribe one. Duration is based on the complexity of the surgery and the duration of risk.
When can I drive?
You cannot drive while taking pain medications (narcotics)
Driving after surgery is a judgement call. If you can get in and out of the vehicle and feel that you can start and stop the vehicle, then you can start driving.
Patients who have had surgery on the left knee, and who have an automatic transmission may drive when they can comfortably get the leg in and out of the car.
Patients who have had surgery on the left knee and have standard transmissions, should not drive until they have good muscular control of the leg. This usually takes 1-6 weeks depending on what type of surgery was performed.
Patients who had surgery on the right knee should NOT drive until they have good muscular control of the leg. This usually takes 1-6 weeks depending on what type of surgery was performed.
When can I return to work?
Return to work is based on the type of work you do and the requirements that are necessary for your occupation.
Please discuss return to work with Dr. Huang and his staff as soon as possible. If you have any specific work related paperwork, please provide it as soon as possible.
