Please note that these instructions are general guidelines to be followed; however, any written or verbal instructions provided by Dr. Mazzara supersede the instructions below and should be followed.

Activity: After your knee microfracture or cartilage implantation, you should be given crutches. These should be used for 6 weeks.  You may put your foot on the ground for balance, but you should not put full weight on the operative leg until we see you in the office. Weight bearing on the knee before the cartilage is healed will cause it not to heal properly and you may need additional surgery.  Elevation of the leg is important for the first day after the surgery as it helps to reduce the leg swelling. After 1-2 days, if your knee is feeling good, you may increase your activity level gradually.

The attached exercises can be started at 48 hours after surgery. A knee brace may be required for 4 weeks after surgery. It may be opened and removed for ice application and for therapy and exercises. Use ice packs to the knee for the first 24-48 hours after surgery. Apply the ice as frequently as needed after surgery. After 24 hours, you may use the ice packs two or more times a day for 20 minutes at a time, if desired for comfort.

For the cartilage to heal properly, you will need to remain non-weight bearing for 6 weeks in most cases.  Our office will arrange for a continuous passive motion machine (CPM) to be delivered to you home.  The company representative who delivers the unit, will explain how it is used.  You are expected to use this for 6 hours a day for 6 weeks.  It is OK to do this in short time periods (1 hour at a time) or all at once (6 hours all at once).  Some patients do this while sleeping.  Our office will do our best to get this authorized by your insurance carrier.  Some carriers pay for 3 weeks, some pay for 6 weeks and some do not cover the expense at all.  The cartilage will heal better if you can use the CPM.  

Start the CPM at 0 to 45 degrees of flexion for at least 6 hours per day. This may be continuously or in shorter periods. If possible, you can sleep in the CPM. Increase the range of motion by 10 degrees per day as tolerated up to a maximum of 90 degrees unless the prescription says otherwise.

Dressings: The post op dressing can be removed 24 hours after surgery, but the knee immobilizer must be worn until you are seen in the office whenever you are not in the CPM. It is normal to have small amounts of drainage of arthroscopy fluid with small amounts of blood on the dressing in the day after surgery.  If the dressing or brace feels too tight after the surgery, remove the brace and Ace bandage and reapply it more loosely.  Once the dressing is removed, clean the incisions with rubbing alcohol and cover the small incisions with Band-Aids after a shower. It is OK to get the arthroscopy incisions wet in a shower after 24 hours but do not soak them in bath water for one week. Re-wrap the leg with the ace bandage after the skin is dry. Only Hibiclens soap may be used on the surgical leg.

Driving:  You may drive a vehicle after 48 hours if you are able to safely operate the vehicleIf your surgery was on your left knee and you have a car with an automatic transmission, you should be mechanically able to perform the functions associated with normal driving.  If your surgery was on your right knee, you are not able to use your right leg to push on the brake or accelerator and will not be permitted to drive.  You cannot drive if you are taking narcotic pain medication.  You may not remove the brace to drive until you are cleared to do so by Dr. Mazzara.

Work:  You may return to work as soon as you feel able and performing your regular job is possible given your activity restrictions.

Medications: You may resume your normal medications that you took prior to surgery. Your prescription for pain medication was sent to your pharmacy before the surgery.  You should not require any more pain medication than we ordered before your first office visit.

If you are not taking the prescribed pain medications, you may take Extra-Strength Tylenol as directed on the label. You may take over-the-counter anti-inflammatory medications such as Advil or Aleve if you know you can tolerate those medications and are not taking blood thinners. Once the nerve block begins to wear off, start your pain medicine.

Unless you are allergic, take one aspirin 81mg twice per day to reduce the chances of blood clots.  Blood clots may occur after any surgery or injury to the leg and may be associated with complaints of calf pain, calf cramping, pain in back of the knee, chest pain or shortness of breath.

Follow up: Make an appointment to be seen the first or second office day after surgery. I will discuss the procedure and the findings during surgery at this visit.

Problems: Complications from knee surgery can occur and you must be aware of the early warning symptoms of some of the more serious problems that may arise. The risk of surgery is never “zero”.

Call the office for a temperature over 101 degrees, pain not controlled by the pain medication, or drainage from the incision that lasts more than 24 hours or calf pain, chest pain, or shortness of breath.

Regular exercise to restore your knee mobility and strength is necessary. Therapy is an essential part of a good result, but some simple exercises can be started when pain permits within 48 hours of surgery. We recommend that you exercise approximately 20 to 30 minutes two or three times a day. The following guide can help you better understand your exercise or activity program that may be supervised by a therapist at the direction of Dr Mazzara and his staff.  As you increase the intensity of your exercise program, you may experience temporary set-backs. If your knee swells or hurts after an exercise activity, you should lessen or stop the activity until you feel better. You should Rest, Ice, Compress (with an elastic bandage), and Elevate your knee (R.I.C.E.). Contact your surgeon if the symptoms persist.
