Post Operative Instructions
Arthroscopic Knee Microfracture
You have undergone a "microfracture" of your knee. In this procedure, a drill or other instrument is used to make small holes (microfractures) in the area where articular (the shellac-like finish covering the joints' surface) cartilage is damaged/missing.
You are non-weight bearing on your surgical leg. You must use your crutches at all times until you are told to discontinue them.
Some degree of swelling of your foot and toes is normal. Swelling can be minimized by elevating your legs. Try to keep your legs up elevated, especially for the first few days. Ideally the leg should be higher than the level of your heart. Swelling can be further controlled by use of ice or cold therapy directly over the sites of surgery. Place a bag of ice or package of frozen vegetables (which nicely conforms to the surgical site), usually 20 minutes on, and 20 minutes off. Do not apply the ice directly to the skin, but either over the dressing or over a towel between the skin and the ice.
Because bleeding from the surgical site cannot escape, it typically travels under the skin to the most "dependent" part of the extremity. An evolving bruising of the foot and/or toes, which can increase over the first few weeks, is normal, and will ultimately resolve.
Keep your dressing dry and in place until the dressing has been removed. You may do this yourself on the 2nd post-op day by un-wrapping the ace bandage and disposing of it and the underlying padding. You will see that there are 2-4 small "arthroscopic" incisions in the front (and sometimes the sides of your knee). You may leave the incisions open to the air, or cover them with Band-Aids. For showering, criss-cross two Band-Aids over each incision. After the shower (NO baths), you may remove them and pat the incisions dry, or you may re-apply Band-Aids. No medicine or ointment is necessary to apply to the incisions. If you prefer, you may wait until your post-op visit for us to remove your dressing. If so, keep it dry while showering. A plastic bag (such as a clean garbage bag) can be applied over the dressing.
A low grade fever (less than 101°) is fairly common within the first 3-5 days following surgery. If the fever is higher or lasts longer, this could reflect infection and warrants contacting our office.
Begin your post-operative exercises the night of surgery. The exercises are illustrated on the following pages. Use your symptoms as a rough guide as to what you can and can't do. However, be careful not to overdo it, as swelling and pain may occur if you do too much. You may drive as soon as you are off pain medication and have complete control of your surgical leg (if it is the right leg) and don't walk with a significant limp. If you are non weight bearing in your right leg this means NO driving until you are told you can weight bear on that leg.
Vicodin® (also known as Hydrocodone), a narcotic pain killer, has been prescribed for pain. Take one to two every six hours as needed for pain, which is typically needed for the first week or so after surgery. All narcotic pain medications can cause side effects, the most common of which is nausea. We have prescribed Phenergan to help with the nausea – take it as you need every 6 hours. If you have known side effects to any of these medications please let us know and we will call in a substitute. Tylenol can be used in place of a narcotic, but NOT in addition to the narcotic. Use Tylenol when pain is less severe. NSAIDs are also a good alternative option.
Pain Medication Tips:
- Do not drive while taking pain medications.
- Do not drink alcoholic beverages while taking pain medications.
- Pain medication should be taken with food as this will help prevent any stomach upset.
- Often pain medications will cause constipation. Eat high fiber foods and increase your fluid intake if possible.
- To alleviate constipation, purchase a stool softener at any pharmacy and follow the recommended directions on the bottle.
DVT (BLOOD CLOT) PRECAUTIONS
Deep Venous Thrombosis (DVT, aka blood clot) is an uncommon complication that can occur following lower extremity surgery. Starting the day after your surgery, take an enteric coated 325mg aspirin (which acts as a blood thinner) twice a day for three weeks. Because aspirin can cause stomach upset, you may want to take it with food. If you have an allergy to Aspirin, please inform us so we can consider alternative precautions. Remember that Tylenol®, Motrin®, Alleve®, and other Non-steroidal Anti-Inflammatory (NSAID) medications do not protect against DVT, and should not be used for this purpose.
You should be scheduled for a post-op appointment 10 – 14 days following surgery, at which time we will review your post-operative program and answer any of your questions. Your post-operative appointment is scheduled on: _______________________________________________.
If you need to verify or change your post-op appointment, please call 703-277-BONE (2663).
Physical therapy is usually started within the first week of your surgery. We will help you in identifying an appropriate therapist if you need assistance.

Knee Arthroscopy Exercise Guide
Regular exercise to restore your knee mobility and strength is necessary. For the most part this can be carried out at home. Your orthopaedic surgeon may recommend that you exercise approximately 20 to 30 minutes two or three times a day. You also may be advised to engage in a walking program. Your orthopaedic physician may suggest some of the following exercises. The following guide can help you better understand your exercise or activity program that may be supervised by a therapist at the direction of your orthopaedic surgeon. As you increase the intensity of your exercise program, you may experience temporary set-backs. If your knee swells or hurts after a particular 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.
Initial Exercise Program
Hamstring Contraction, 10 Repetitions - No movement should occur in this exercise. Lie or sit with your knees bent to about 10 degrees. Pull your heel into the floor, tightening the muscles on the back of your thigh. Hold 5 seconds, then relax.Repeat 10 times.
Quadriceps Contraction, 10 Repetitions - Lie on stomach with a towel roll under the ankle of your operated knee. Push ankle down into the towel roll. Your leg should straighten as much as possible. Hold for 5 seconds. Relax. Repeat 10 times.
Straight Leg Raises, 10 Repetitions - Lie on your back, with uninvolved knee bent, straighten your involved knee. Slowly lift about 6 inches and hold for 5 seconds. Continue lifting in 6-inch increments, hold each time. Reverse the procedure, and return to the starting position. Repeat 10 times. Advanced: Before starting, add weights to your ankle, starting with 1 pound of weight and building up to a maximum of 5 pounds of weight over 4 weeks.
Buttock Tucks, 10 Repetitions - While lying down on your back, tighten your buttock muscles. Hold tightly for 5 seconds. Repeat 10 times.
