What causes knee pain
Knee pain can be caused by various factors, including osteoarthritis, ligament injuries, meniscus tears, and overuse. It can also result from muscle strain and other soft tissue injuries in the knee area.
Common Conditions that Cause Knee Pain

Osteoarthritis of the Knee
Osteoarthritis is the most prevalent form of knee arthritis due to the gradual deterioration of protective cartilage in the joint. It can cause pain, swelling, stiffness, and reduced mobility, with treatment options depending on its severity, including lifestyle changes, therapy, medication, or surgery.

Anterior Cruciate Ligament (ACL) Injury
An ACL injury is a common occurrence, particularly among athletes involved in sports that require sudden stops, changes in direction, or jumping. The ACL is one of the major ligaments in the knee, providing stability and facilitating controlled movement. Injury to the ACL often results in pain, swelling, instability, and limited knee function. Treatment may involve rest, physical therapy, or surgical reconstruction for severe tears.

Meniscal Tear
A meniscal tear is a knee injury that can cause pain and discomfort. It happens when the cartilage in the knee (the meniscus) gets damaged, often due to twisting or wear and tear. This injury can affect both athletes and older individuals. Treatment options vary depending on the severity, ranging from rest and physical therapy to surgery.

Knee Fractures
Knee fractures can result from traumatic injuries or falls, leading to severe knee pain and limited mobility. These fractures can involve different parts of the knee, such as the patella (kneecap), femur (thigh bone), or tibia (shinbone). Treatment options depend on the type and severity of the fracture and may include casting, bracing, or surgical intervention to ensure proper healing and alleviate knee pain.
Recognizing Knee Injury Signs
Hearing a popping sound and feeling the knee give way during the injury.
Experiencing pain and swelling in the knee.
Encountering difficulty in fully straightening or moving the knee.
Starting to limp due to discomfort.
If you encounter any of the above symptoms do not delay seeking consultation with an orthopaedic doctor to prevent potential further harm.
Our knee specialist is here to assist in identifying the cause of the injury and provide effective relief.

- Knee Arthroscopy
Partial Knee Replacement Performed by Dr Alvin Tan
Partial knee replacement, or unicompartmental knee arthroplasty, is a minimally invasive surgery that replaces only the damaged part of the knee joint while preserving healthy tissue, making it an alternative to total knee replacement.
Partial knee replacements are often performed as day surgery or short-stay procedures. In contrast, patients who undergo total knee replacements typically stay in the hospital for 1 to 2 days.
After the initial hospitalization, patients with partial knee replacements experience quicker returns to daily activities, reduced reliance on walking aids, and earlier resumption of work and hobbies.
Am I Suitable for Partial Knee Replacement?
Consult with our knee specialist to determine the appropriate knee replacement for your specific condition.


Robotic Knee Surgery
Dr. Alvin specializes in Robotic Knee Replacement, a surgical technique that utilizes robotics technology to enhance the precision of total knee replacement. This technology assists in achieving more accurate alignment and positioning of knee implant components, potentially improving implant longevity and function.
There are several benefits to undergoing a robotic knee replacement. These include :
Enhanced Precision and Accuracy
Personalized Knee Balancing
Preservation of Healthy Tissue
Robotic knee replacement surgery brings significant advantages. This advanced technology is transforming knee replacement surgery. If you're considering knee replacement, consult with us to discuss the potential benefits of robotic knee replacement and determine if it's suitable for you. Together, you can make an informed decision and embark on a journey towards restored mobility and an active, pain-free lifestyle.
