The knee joint is stabilized by four ligaments. Ligaments are rope-like structures that connect one bone to another. They serve to allow functional range of motion and then restrict excess motion of the joint. The anterior cruciate ligament (ACL) is one of the most commonly torn ligaments in the knee.

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 2-4 weeks after surgery. If you are not stable with crutches, then consider a walker.

  • Obtain knee brace: the knee brace is designed to be used for the first 4 weeks after surgery. It will initially be locked straight right after surgery. You should unlock it so that it can bend on day 1 or 2 after surgery when your comfort has improved. The brace shop will demonstrate how to lock and unlock the brace.

  • 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 and knee brace!

  • 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

  • You will be instructed to be on crutches for 2-4 weeks total. Your weight bearing will be 30% which means that you can put the weight of the leg down on the ground for balance. The rest of your weight should be on your good leg and on your arms using the crutches.

Surgery Dressing

This video will show you what to do on the first day after surgery to get the dressings removed:

  1. 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.

  1. Keep up with your fluids and nutrition.

  2. Start physical therapy. Click here for the physical therapy protocol if you need it.

  • 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.
