Meniscus (cartilage) Repair patients cannot do twisting, pivoting, squatting, deep knee bends or impact activities for four months. It is vital that meniscus repair patients do not squat for at least four months after the repair.
Most people can walk with crutches soon after meniscus surgery. Many return to normal activities within six to eight weeks. Your healthcare provider may recommend low-impact activities rather than high-impact (such as walking rather than running). If you have a physical job, you may need extra time off work to recover.
Crutches will be necessary for 2-7 days after surgery. Rehabilitation to gain full ROM should occur within 1-2 weeks. Heavy work or sports may be restricted for the first 4-6 weeks. Complicated arthroscopic repair of a meniscus tear requires that the patient's knee be completely immobilized for 2 weeks after surgery.
Avoiding twisting activities may decrease the symptoms from a torn meniscus. Additionally, one should do quadriceps setting exercises with the knee straight or mini-squats, bending only to 15 degrees, to prevent giving way and keep the quadriceps muscle from atrophying.
Your doctor might recommend: Rest. Avoid activities that aggravate your knee pain, especially any activity that causes you to twist, rotate or pivot your knee. If your pain is severe, using crutches can take pressure off your knee and promote healing.
It may take as long as 6 months before your knee is strong enough for hard physical work or certain sports. You will need to build your strength and the motion of your joint with rehabilitation (rehab) exercises. In time, your knee will likely be stronger and more stable than it was before the surgery.
For a general timeframe, many runners can begin a (safe) return to running program around 8-12 weeks post-op. This timeline provides enough time to significantly reduce swelling, improve strength at the hip and quadriceps muscles, and implement a gradual progression/training plan to resume proper walking mechanics.
Don't Overdo It
Although exercise is the key to healing, you could be backpedaling progress by overworking your knee.
You can walk with your full weight on both legs (unless your surgeon has given you specific instructions). You can walk up and down stairs.
You will recover more quickly if you carefully follow all your doctor's instructions. In your first days after surgery, you will need apply ice frequently and elevate your knee above your heart to help relieve swelling. Be sure to get plenty of sleep, to help your body heal.
Depending on the type of procedure you received, you may be asked to avoid fully bearing weight on the affected knee for up to six weeks. You may be able to climb stairs a few days after surgery, but it's important to be careful and go slowly. You should use handrails for support and take one step at a time.
To avoid placing stress on the meniscus repair, do not bend your knee beyond 90 degrees (bent to a right angle). Brace and Crutches: Unless otherwise instructed by your doctor, use crutches when walking and bear weight as tolerated on the operated leg. Wear the post-operative brace for walking.
When a true meniscus repair is performed, your surgeon is likely to recommend a period of limited weight-bearing (using crutches or walker for walking) and limited motion. They may also recommend using a knee brace. These measures are taken in order to protect the repair and give it a chance to heal.
Meniscus tear
According to the study, as many as 36.4% of people who undergo medial meniscus surgery will re-tear their medial meniscus. The risk of re-tearing the lateral meniscus is much lower.
2-4 Weeks. From 2 to 4 weeks, patients will advance to full weight bearing as tolerated by pain; however, they will not be allowed to full weight bear past 90 degrees of flexion. This phase will start to initiate closed chain exercises, such as terminal knee extensions with or without resistance bands.
Most meniscal surgeries (95%) are partial meniscectomies where part of the meniscus is actually removed, not just repaired. Therefore, the remaining meniscus is now smaller and does not perform as well.
In general, it's better to fix the meniscus than to remove it. Some types of tears can't be fixed. For example, radial tears sometimes can be fixed, but it depends on where they are. But most horizontal, long-standing, and degenerative tears—those caused by years of wear and tear—can't be fixed.
Pain and pain management
Arthroscopic meniscus repair is moderately painful. Because more soft tissue surgery is performed, it is more painful than a standard arthroscopy, but less painful than a ligament reconstruction or another procedure that requires drilling holes through the bone.
Physical Therapy
Low-impact exercises such as stationary biking may reduce your level of pain, improve mobility, and restore function to the area around the meniscus tear. As your knee and muscles grow stronger, your physical therapist guides you in returning to more vigorous activity.
Walking up or down stairs may be particularly painful, and may also cause increased swelling in the knee.
Avoid positions and activities that place excessive pressure on knee until pain and swelling resolve. Problematic positions include squatting, pivoting, repetitive bending (eg, climbing stairs, rising from seated position, operating clutch and pedals), jogging, and swimming using the frog or whip kick.
Tip #1: Avoid Sitting With Your Knee Bent Or Cross-Legged
To give your knees relief, limit the amount of time you spend with your knees bent or crossed. Try to have them straight whenever possible. If you have to sit with your knees crossed or bent, limit it to 20 minutes at a time before getting up and moving around.
