ACL Reconstruction, Meniscus & Cartilage Surgery
Knee pain, instability, locking, swelling, or a sports injury can make everyday movement feel uncertain. Whether you have torn your ACL, damaged your meniscus, or injured the cartilage in your knee, early assessment and the right treatment plan can make a major difference to your recovery. Dr NP van der Watt offers expert evaluation and treatment for ACL injuries, meniscus tears, and cartilage damage, with a focus on restoring stability, preserving the knee joint where possible, and helping patients return to movement with confidence. His current website already positions him as an orthopaedic surgeon with expertise beyond joint replacement, including joint preservation, reconstruction, and sports-related injuries.
What Conditions Does This Page Cover?
This service page focuses on three key structures in the knee:
ACL Injuries
The anterior cruciate ligament, or ACL, is one of the main stabilising ligaments in the knee. It helps control twisting and forward movement of the shin bone. ACL injuries often happen during sport, especially with sudden changes of direction, jumping, pivoting, or awkward landings.
Meniscus Tears
The meniscus is the shock-absorbing cartilage pad inside the knee. Each knee has two menisci. These structures help distribute load, improve joint stability, and protect the cartilage surfaces.
Cartilage Damage
Articular cartilage is the smooth lining that covers the ends of the bones inside the knee joint. When this cartilage is damaged, movement can become painful, swollen, stiff, or mechanically limited.
Common Symptoms
You may need an orthopaedic assessment if you are experiencing:
- Knee instability or a feeling that the knee gives way
- Pain with twisting, pivoting, bending, or weight-bearing
- Swelling after sport or activity
- Locking or catching in the knee
- Difficulty straightening or bending the knee fully
- Clicking, sharp pain, or recurrent joint swelling
- Reduced confidence returning to sport or exercise
Procedure
ACL Reconstruction
What is a ACL Reconstruction?
An ACL tear can make the knee feel unstable, especially during sport, quick turns, or uneven movement. Some partial injuries can be managed conservatively, but in many active patients, a full ACL rupture may require reconstruction to restore stability and protect the rest of the knee from further damage.
When ACL reconstruction may be considered
ACL reconstruction may be recommended when:
- The knee remains unstable
- You want to return to pivoting or high-demand sports
- There is associated meniscus or cartilage damage
- Recurrent instability is increasing the risk of further injury
- Non-surgical treatment has not provided enough function or confidence
The goal of ACL reconstruction
The aim is to restore stability to the knee, reduce episodes of giving way, and help protect the meniscus and cartilage from ongoing damage. Surgery is usually followed by a structured rehabilitation programme, which is a critical part of the overall recovery.
Meniscus Treatment
What is a Meniscus Treatment?
The meniscus plays a major role in knee function. A tear can happen through sport, twisting injuries, trauma, or gradual degeneration over time.
Symptoms of a meniscus tear
Meniscus injuries can cause:
- Joint line pain
- Swelling
- Locking or catching
- Pain with squatting or twisting
- Difficulty fully bending or straightening the knee
Meniscus treatment options
Treatment depends on the type, size, and location of the tear, as well as your age, activity level, and symptoms. Options may include:
Conservative treatment
Some tears can be managed without surgery through rest, activity modification, physiotherapy, and anti-inflammatory strategies.
Meniscus repair
Where possible, preserving the meniscus is often the preferred option. Repair may be appropriate for certain tear patterns, especially in younger or active patients.
Meniscus surgery
In some cases, the damaged portion may need to be carefully trimmed if the tissue is not repairable. The goal is always to preserve as much healthy meniscus as possible.
Cartilage Injuries and Cartilage Repair
What is cartilage Injuries
Cartilage damage can occur from trauma, sport, instability, wear, or associated knee injuries. Because cartilage has limited healing potential, these injuries need careful assessment.
Symptoms of cartilage damage
Cartilage injuries may cause:
- Pain during activity
- Swelling after exercise
- Stiffness
- Catching or grinding sensations
- Ongoing knee discomfort that does not fully settle
Treatment for cartilage damage
Cartilage treatment depends on the size, depth, and location of the defect, along with your age, activity goals, and the overall condition of the knee.
Management may include:
- Activity modification and rehabilitation
- Non-surgical symptom management
- Joint preservation strategies
- Surgical cartilage procedures where appropriate
- Correction of associated issues such as instability or meniscus injury
The right plan is highly individual. In many cases, cartilage treatment works best when the whole knee is considered, not just the cartilage defect in isolation.
Diagnosis, Treatment & Recovery
Early Assessment
Why Early Assessment Matters
ACL, meniscus, and cartilage injuries are closely linked. An unstable knee can place more stress on the meniscus. Meniscus damage can increase pressure on the cartilage. Cartilage injuries can lead to persistent pain and long-term joint problems if left untreated.
This is why a proper diagnosis matters. A thorough clinical assessment, together with the right imaging, helps determine:
- What structure is injured
- Whether surgery is necessary
- Whether joint preservation is possible
- The best path back to daily activity, work, or sport
Diagnosis and Evaluation
Clinical Examination
A detailed knee assessment helps identify instability, swelling, range of motion issues, tenderness, and mechanical symptoms.
Imaging
X-rays may be used to assess bone alignment and joint condition, while MRI is often useful for evaluating soft tissue injuries such as the ACL, meniscus, and cartilage. Dr van der Watt’s current site already references imaging, including MRI where cartilage damage is suspected.
Individualised Treatment Planning
Treatment is based on your injury, lifestyle, activity goals, symptoms, and long-term joint health.
Treatment
Treatment Approach
Dr van der Watt’s broader site messaging centres on patient-first care, evidence-based treatment, and tailored recovery planning. This page follows that same approach.
Not every ACL injury needs surgery. Not every meniscus tear should be trimmed. Not every cartilage lesion is treated the same way.
The aim is to choose the right treatment for the right patient at the right time.
This may include:
- Conservative management
- Physiotherapy-led rehabilitation
- Arthroscopic assessment and treatment
- ACL reconstruction
- Meniscus repair or preservation-focused surgery
- Cartilage procedures and joint preservation strategies
Who May Benefit From Seeing Dr van der Watt?
You may benefit from a consultation if you:
- Injured your knee playing sport
- Heard a pop during a twisting movement
- Have ongoing swelling after activity
- Feel your knee giving way
- Have locking or catching symptoms
- Have been told you have an ACL tear, meniscus tear, or cartilage injury
- Want a specialist opinion before deciding on surgery
Recovery
Recovery and Rehabilitation
Recovery depends on the exact diagnosis and treatment. Some patients improve with targeted rehabilitation alone. Others need surgery followed by a structured physio programme.
Rehabilitation may focus on:
- Reducing swelling
- Restoring range of motion
- Rebuilding strength
- Improving control and stability
- Guiding a safe return to sport or activity
For ACL and other reconstructive knee procedures, rehab is a key part of the outcome. Good surgery and good rehabilitation work together.

FAQ
Clear answers for your peace of mind. We address the most common patient concerns regarding recovery timelines, driving, and maintaining your new knee.
What is the difference between an ACL tear and a meniscus tear?
An ACL tear affects one of the main stabilising ligaments in the knee, while a meniscus tear affects the shock-absorbing cartilage pad inside the joint. Both can happen together.
Do all ACL tears need surgery?
No. Some patients can manage well without surgery, depending on their symptoms, activity level, and knee stability. Others, especially active patients with instability, may benefit from reconstruction.
Can a meniscus tear heal on its own?
Some meniscus tears can settle with conservative treatment, while others may need surgical repair or arthroscopic treatment. It depends on the type and location of the tear.
What does cartilage damage in the knee feel like?
Cartilage damage may cause pain, swelling, stiffness, catching, or persistent discomfort during and after activity.
Can ACL, meniscus, and cartilage injuries happen together?
Yes. These injuries often overlap. For example, an ACL injury can happen with a meniscus tear, and ongoing instability can increase the risk of cartilage damage.
How do I know if I need to see a knee specialist?
If your knee is unstable, swollen, locking, painful, or not improving after an injury, it is worth getting an orthopaedic assessment.
