The first thing that can happen after an acute injury is swelling around the site of the injury. When the knee is injured, it can swell as a result of inflammation or possibly bleeding into the knee joint. If the knee swells without an acute injury, it is also wise to consult your doctor.
Reduced range of motion can be related to swelling in the knee, as well as other joint injuries. If you have limited range of motion that does not begin to improve within a few days, you should contact your doctor. If there is knee instability, you should also consult your doctor.
Please consult a knee specialist if knee pain is severe or does not resolve satisfactorily after an injury. If there is persistent pain without an injury, it will also be beneficial to seek a specialist’s advice.

Dr Ong Kee Leong is a senior consultant orthopaedic surgeon with subspecialty training in shoulder, knee, and arthroscopic sports surgery.
Dr Ong practises at a clinic in Singapore with access to accredited hospital facilities for surgical procedures. Patients have access to diagnostic imaging (X-ray, MRI, and ultrasound), day surgery facilities for arthroscopic procedures, and structured rehabilitation services.
Please contact the clinic directly for the current practice address, nearest MRT station, and details of affiliated surgical facilities.
Dr Ong’s clinical approach is grounded in a single principle: exercise and sports are highly beneficial for long-term health. This reflects a genuine belief that physical activity is central to long-term health, and that the goal of orthopaedic care is to return you to the activities that matter to you, not simply to resolve your imaging findings.
In practice, this means prioritising joint preservation wherever possible. Rather than moving quickly to joint replacement or highly invasive procedures, the focus is on treatments that protect and restore the body’s natural structures.
Every plan is shaped by what you want to do with your body, whether that is returning to competitive sport, running at weekends, or simply walking without pain.
Beyond acute treatment, Dr Ong incorporates injury prevention and load management guidance into his consultations. Understanding why an injury occurred, and how to modify training to reduce the risk of recurrence, is part of the long-term care approach.
Knee pain occurs when there is a pain that is in or around your knee joint. The pain can be caused by problems with the knee joint itself, or by conditions that affect the soft tissues, ligaments or tendons around the knee.
There could be a variety of causes for your knee pain, such as injury. Sometimes, there could be persistent pain without an injury as well as a result of conditions (e.g. arthritis, tendonitis) or infection.
If your knee pain is severe or does not resolve satisfactorily after an injury, visiting an Orthopaedic specialist is the best way forward to get an accurate diagnosis and treatment.
We treat a variety of knee conditions, including bone fractures, ligament tears and joint mobility issues:
When your knee pain becomes more persistent, the treatment options may be beyond your GP’s expertise.
You should seek specialist medical advice from an orthopaedic surgeon if you experience any of the following:
If your knee pain is affecting your quality of life and you cannot perform everyday activities (such as standing or walking) it is highly advisable to see an orthopaedic surgeon for a detailed diagnosis and advice.
Dr. Ong always advises patients to listen to their bodies and not push through the pain barrier. If your pain does not subside with RICE (rest, ice, compression and elevation) and over-the-counter painkillers, it is highly advisable that you seek professional medical advice. Continuing with sporting activities will place additional strain on your shoulder and worsen the condition.
At your first appointment with Dr. Ong, he will evaluate your medical history and the pain you are experiencing.
Depending on the symptoms you have, he will likely perform some form of diagnostic imaging (e.g. X-Rays or MRI scans) to assess your condition accurately. X-rays and CT scans are useful to rule out bony problems, whilst an MRI scan is excellent at looking at soft tissue (e.g. tendons, ligaments, cartilage) problems.
After assessing your condition, Dr. Ong will recommend a personalised treatment plan, according to your specific needs. This may include surgical or non-surgical treatment options.
After diagnosis, Dr. Ong will advise an individualised treatment plan that is customized to your specific needs. The treatment plan varies from patient to patient, and the condition you have.
For less severe problems, Dr. Ong may recommend a non-surgical management plan (such as painkillers and physiotherapy) to treat your condition initially. If your symptoms do not improve or even worsen over the course of this treatment, Dr. Ong will review the treatment protocol and may advise surgery.
Dr. Ong will only recommend surgical options when all other conventional non-surgical interventions have failed, or if non-surgical options will not work for your condition. For example, if you have a broken bone which is extremely painful and debilitating, you may benefit from immediate surgery.
Consultation fees are charged based on length of consultation, and start from SGD$200 (within 30 minutes).

During your consultation, Dr. Ong will evaluate your medical history and the pain you are experiencing. You may also ask Dr. Ong any questions you may have about your condition.

As you go through your treatment plan, Dr. Ong will follow up with you every step of the way, ensuring that you receive the dedicated care you deserve.
The initial step in managing knee pain is an accurate diagnosis.
A knee specialist employs a comprehensive approach that includes a detailed patient history, physical examination, and the use of diagnostic imaging techniques such as X-rays, MRI scans, and ultrasounds.
Once a diagnosis is established, the knee specialist develops a tailored treatment plan aimed at alleviating pain, restoring function, and preventing further injury. Treatment strategies may include non-surgical or surgical interventions.
In addition to treating the immediate symptoms, knee specialists also focus on preventing future issues through patient education and guidance on proper knee care.
Knee pain can develop from various sources, ranging from acute injuries to degenerative changes.
Your knee relies on four major ligaments for stability. Sports activities, falls, or sudden directional changes can stretch or rupture these crucial structures. ACL injuries are particularly common in pivoting sports, while MCL tears often result from direct contact. These injuries typically cause immediate swelling, instability, and difficulty weight-bearing.
The C-shaped cartilage in your knee can tear from rotational movements or degenerate over time. Athletes often experience acute tears during twisting motions, while older patients may develop degenerative tears from normal wear. Symptoms include mechanical catching, clicking sounds, and episodes where the knee feels “stuck.”
Knee arthritis develops when the smooth joint surfaces gradually wear away, leading to bone-on-bone contact. This progressive condition commonly affects active individuals and those with previous injuries. Morning stiffness, pain with prolonged walking, and difficulty with stairs are hallmark symptoms.
Repeated stress from running, jumping, or squatting can inflame the tendons around your kneecap. This condition, often called “jumper’s knee,” creates localized pain that intensifies with activity and may persist even during rest phases.
