How Can Damaged Knee Cartilage Be Repaired?

Damaged knee cartilage can be treated with non-surgical methods, such as guided exercises and PRP injections, to improve joint mobility. In severe cases, surgical procedures like microfracture, grafting, or cellular resurfacing help restore the joint surface and support tissue repair.

At Total Orthopedics and Sports Medicine, our doctor, Dr. Michael K. Shindle, performs a detailed physical exam and reviews your medical history to design a personalized treatment plan. At an early stage, he guides you through targeted exercises to delay the need for total knee arthroplasty. Beyond this, we accept major insurance plans to help you avoid unnecessary treatment delays.

How Do Doctors Repair Knee Cartilage Damage?

Our doctor, Dr. Michael K. Shindle, uses minimally invasive techniques to treat cartilage damage, depending on the injury’s size and severity. For example, at an early stage of damage, he may recommend hyaluronic acid, PRP therapy, and anti-inflammatory medicines to improve movement. Beyond this, PubMed research reports that pulsed electromagnetic field (PEMF) therapy, applied for 30 minutes, three times per week, can increase cartilage thickness. It may also help improve muscle strength and enhance movement.

In addition, the following approaches also help reduce stress on the joint and improve daily function:

• Targeted Exercise Programs: Improve joint control and support the injured knee
• Cold Therapy: Helps reduce swelling and ease discomfort
• Activity Modification: Reduces stress on the joint to prevent further damage
• Weight Management: Lowers pressure on the cartilage in the knee
• Bracing Support: Provides stability and reduces strain during activity
• Lifestyle Adjustments: Helps reduce symptoms and supports long-term joint health

However, if you have severe articular cartilage defects, Dr. Michael K. Shindle may guide you to advanced procedures like microfracture, grafting (autograft/allograft), or the MACI procedure. He performs these procedures arthroscopically to minimize tissue damage and allow faster recovery.

During surgery, he carefully prepares the damaged area and performs the selected technique to restore the joint surface. Once the surgeon completes the repair, he checks the area to ensure proper alignment and stability. After the procedure, he may also guide recovery to improve movement and support healing.

What Does Early Knee Joint Damage Feel Like?

At an early stage of cartilage damage, you may experience knee pain that worsens during or after activities such as walking, climbing stairs, or standing for long periods. You may also notice joint stiffness, along with a grinding or clicking sensation during movement. Beyond this, slight swelling or warmth around the knee joint may develop, which signals a cartilage lesion.

In some cases, you may notice increased discomfort during weather changes, especially with high humidity or low pressure. As the damage progresses, you may notice more severe symptoms, including:

• Constant, Intense Pain: Deep pain that does not ease with rest and may disturb sleep
• Reduced Range of Motion: Limited movement that makes bending or straightening the knee difficult
• Joint Instability: Knee feels weak, wobbly, or may suddenly give way
• Joint Locking: The knee may feel stuck or unable to move smoothly
• Visible Changes: Swelling, warmth, or changes in knee shape due to bone growth

Is Cartilage Loss Normal With Aging or Arthritis? 

Yes, the smooth cushioning tissue in your knee can gradually wear out as you age. This often happens because the blood supply to the tissue is limited, which slows its ability to repair itself. Over time, the cartilage tissue loses water content and becomes less elastic due to age-related degeneration.

However, severe cartilage damage may indicate osteoarthritis, which can lead to ongoing joint pain and reduced cartilage function. In fact, a study published in the BioMed Research International journal reports that nearly half of people aged 65 and older experience osteoarthritis. Over time, this discomfort can lead to the following long-term knee joint conditions:

• Bone-on-Bone Friction: Loss of cartilage in the knee leads to severe pain during movement due to bone friction.
• Bone Spurs (Osteophytes): Extra bone growth forms around the joint, which can cause pain and a reduced range of motion.
• Chronic Synovitis: Ongoing inflammation in the joint lining leads to swelling and fluid buildup.
• Baker’s Cyst: Fluid collects behind the knee, forming a swelling that causes tightness and discomfort.
• Joint Instability: Weak support structures make the knee feel unstable or give way during activity.
• Meniscus Damage: Loss of meniscus cartilage increases the risk of tears and further joint stress.

Note: If you experience persistent knee pain or instability, consult a doctor for a proper physical exam and joint assessment to prevent further damage.

Can PRP Injections Help Support Joint Healing?

Yes, platelet-rich plasma (PRP) injections help relieve pain and support joint healing in an injured knee. During the procedure, the doctor numbs the injured area with a local anesthetic. Then, they use ultrasound guidance to precisely inject PRP into the joint space. Once injected, these platelets activate and release growth factors that initiate a natural repair process in the knee cartilage.

Moreover, PRP releases anti-inflammatory signals that help reduce swelling and ease discomfort in the knee joint. It also supports cartilage cells to produce more collagen, which helps repair cartilage and maintain normal cartilage function. Beyond this, it promotes new blood vessel growth, improving nutrient flow to the subchondral bone and surrounding tissues. Over time, this process supports the regeneration of articular cartilage and improves joint movement.

In fact, NIH research examined PRP treatment in 89 patients with knee osteoarthritis. After three months of follow-up, the study reported the following clinical outcomes:

• Improved Joint Function: WOMAC score improved from 37 to 18.8
• Reduced Pain Levels: VAS score improved from 8.42 to 4.91
• High Patient Satisfaction: About 70% of patients reported positive results

How Do Stem Cells Help Regenerate Knee Tissue?

Stem cells, such as mesenchymal stem cells, release growth factors that support natural healing and help form new articular cartilage. They also release anti-inflammatory cytokines (signaling proteins that reduce inflammation), which help ease pain. Rather than directly forming new cartilage, these cells primarily signal nearby cells to support tissue repair. In some cases, they may contribute to cartilage-like tissue formation, although this effect is still being studied.

Which Surgery Works Best for Knee Cartilage Loss?

Our experienced surgeon, Dr. Michael K. Shindle, recommends advanced techniques like the MACI cartilage surgery and osteochondral autograft transplantation (OATS) to repair damaged cartilage in younger patients. In severe cases, he may guide you toward total knee replacement if you have extensive articular cartilage damage and ongoing joint pain. However, the appropriate surgical procedures depend on your age, activity level, and the size of the cartilage defect in the patient’s knee.

Moreover, our surgeon, Dr. Michael K. Shindle, may recommend the following common procedures based on your knee condition:

• Arthroscopic Debridement: A minimally invasive arthroscopic surgery that removes loose, damaged cartilage to relieve symptoms.
• Microfracture Technique: Small holes are created in the underlying bone to release marrow cells and stimulate fibrocartilage repair tissue.
• Autologous Chondrocyte Implantation (ACI): Cartilage cells are collected, grown in a lab, and implanted into the damaged area to help repair larger cartilage defects.
• Osteochondral Allograft Transplant: Uses donor cartilage tissue to repair large lesions and restore the joint surface.
• Meniscus Repair or Transplant: Replaces meniscus cartilage (the joint’s natural shock absorber) to protect the knee joint and improve function.
• Open Surgery: In complex cases, surgeons may use open surgery to directly access the joint and repair damaged cartilage more precisely.

Can Microfracture Surgery Fix Damaged Knee Cartilage?

Yes, microfracture surgery is a minimally invasive arthroscopic procedure designed to repair damaged cartilage in the knee. During the procedure, surgeons make small incisions and use a sharp tool such as an awl (a pointed surgical instrument) to create tiny holes in the underlying bone. This process releases cells from your own blood, which form new cartilage (a scar-like tissue) to reduce joint pain and improve movement.

In fact, NIH research on 71 patients shows that about 70% of cases achieved more than 50% coverage of the damaged area with repair tissue within 2 years. Research also found that around 9% of patients achieved full cartilage recovery, while 7% developed excess repair tissue during healing. After 1 year of follow-up, most patients showed significant improvement in knee pain and function.

However, doctors often recommend this cartilage repair procedure for individuals aged 45 or younger with smaller lesions caused by traumatic injury rather than widespread arthritis. The overall outcome after the procedure also depends on the following factors:

• Size of the Defect: Smaller areas of damaged cartilage show better results with the microfracture technique.
• Location in the Joint: Outcomes vary based on where the damage exists in the patient’s knee.
• Age and Activity Level: Younger, active patients often show a stronger healing response.
• Condition of Surrounding Tissue: The health of the underlying bone and nearby cartilage supports better recovery.
• Post-Surgery Care: Proper rehab steps, including restricted weight bearing, help protect the repair and improve healing.

How Do We Help Athletes Protect Their Knees Long-Term?

At Total Orthopedics and Sports Medicine, our sports medicine specialist, Dr. Michael K. Shindle, focuses on injury prevention and biomechanical correction. If needed, he guides you through joint preservation techniques such as osteotomy and meniscal transplantation. Beyond this, we support you with neuromuscular training (muscle control), strengthening, and low-impact exercise plans to protect your knee’s long-term health.

Here are key strategies and preventive approaches that Dr. Michael K. Shindle uses to protect the knee joint:

Neuromuscular Training and Retraining

A PubMed study found that neuromuscular training improves joint stability in patients after musculoskeletal or cartilage injuries. It reduces tibial anterior displacement (forward movement of the shin bone) on both affected and healthy sides, helping control knee joint movement. It also increases muscle activation in key knee-supporting muscles, such as:

• Vastus Medialis Oblique (helps stabilize the kneecap and keep it aligned)
• Vastus Lateralis (supports knee extension and controls outer knee movement)
• Biceps Femoris (helps bend the knee and supports backward leg movement)
• Semitendinosus (assists in knee bending and improves joint stability)

Similarly, a NIH meta-analysis of 27,231 participants shows that neuromuscular training reduces ACL injury risk by about 49%. It also reports that a greater risk reduction of about 62% in younger athletes compared to about 35% in older athletes.

Personalized Exercise Programs

Before surgery, our surgeons examine your condition and design a personalized exercise plan. This program includes strength training, cardiovascular conditioning, range-of-motion exercises, and balance work. Through this targeted approach, he prepares your body to improve recovery and protect healthy cartilage tissue in the affected area. This approach helps you recover faster and improves the overall function of the knee articular cartilage.

Our doctors, Dr. Michael K. Shindle, also design strength programs to target weak muscles and improve knee joint stability. This approach helps control movement and lowers the risk of knee cartilage injury over time. To achieve these benefits, you can include the following exercises in your daily routine:

• Half Squats: Bend your knees slightly while keeping your chest up to build quad strength and support the knee joint.
• Glute Bridges: Push your hips upward from the floor to activate your glutes and keep your knees properly aligned.
• Clamshells: Open your top knee while lying on your side to strengthen hip muscles that control knee position.
• Straight-Leg Raises: Lift a straight leg while lying down to strengthen quads without adding pressure to the joint.
• Hamstring Curls: Bring your heel toward your body while standing to improve hamstring strength and support movement.
• Step-Ups: Step onto a low platform slowly and carefully to improve balance and leg strength.
• Side-Steps with Band: Move sideways with a resistance band to strengthen hips and improve overall joint stability.

Injury Prevention Protocols

As an experienced Orthopedic Consultant of the New York Football Giants, Dr. Michael K. Shindle guides you with evidence-based injury prevention techniques to protect the knee joint long-term. He focuses on reducing load, building muscle support, and correcting movement patterns to lower stress on the joint. These plans also support better control and long-term joint health. In fact, NIH meta-analysis of 28,176 athletes reports that structured training programs reduce the risk of knee injuries by about 25%.

Beyond this, Dr. Michael K. Shindle guides you about gradual load management, proper footwear, and protective support during activity, such as:

• Custom Orthotics: Shoe inserts that correct foot alignment and reduce pressure on the knee joint.
• Sport-Specific Footwear: Shoes designed for your sport to improve stability and lower joint stress.
• Knee Braces: External support that helps stabilize the joint during high-impact movements.
• Support Sleeves: Compression sleeves that improve circulation and provide mild joint support.

Posture and Movement Correction

According to PubMed research, athletes who control whole-body movement maintain stability and reduce the risk of knee injuries during rapid movements. This study found that trained athletes use better movement strategies, especially by engaging the hips to support the knee joint. For this reason, our surgeon, Dr. Michael K. Shindle, guides you in improving posture and movement patterns to reduce strain and improve control.

Structured Follow-Up Care

To monitor your recovery progress, Dr. Michael K. Shindle offers structured follow-up appointments. During these visits, he tracks healing response, measures the range of motion, and reviews your knee joint movement. If needed, he will adjust your treatment plan to improve outcomes and prevent further cartilage damage in your knee. This ongoing care helps you recover safely and maintain long-term joint health.

Healthy Lifestyle Guidance

Poor diet, low activity, or excess strain on the joint can increase stress on the damaged articular cartilage and slow recovery. In such cases, our surgeon, Dr. Michael K. Shindle, guides you through balanced nutrition, weight control, and low-impact activities to support healing. This approach helps reduce strain on the knee joint and protects long-term function. Call 855-321-6784 to ensure smooth healing and long-term knee joint health.

How Much Does Knee Cartilage Repair Treatment Cost?

In New Jersey, cartilage repair costs range from $3,000 to $60,000+, depending on the procedure. More advanced options, such as osteochondral allograft transplantation, can cost around $75,000. On the other hand, minimally invasive options like OATS (a procedure that transfers your own healthy cartilage tissue) usually cost around $45,000. The final cost of cartilage repair also depends on the following key factors:

• Type of Facility: Hospitals usually charge higher operational costs, while specialized centers focus on specific surgical procedures and may offer lower pricing.
• Surgeon’s Experience: Orthopedic surgeon with expertise in cartilage repair surgery, may charge a high fee.
• Insurance Coverage: Many plans (including Medicare/Medicaid) cover necessary surgery, but you may still pay deductibles or co-insurance.
• Severity and Location of Damage: Extensive cartilage damage often requires advanced techniques, which increases overall costs.
• Imaging and Pre-Treatment Tests: MRIs and X-rays help assess knee cartilage damage and guide the treatment plan, but they also increase the upfront surgery cost.
• Rehabilitation Requirements: Mobility aids and equipment, such as motion machines, support healing. However, they also increase the final medical bills after surgery.
