Knee osteoarthritis is a common degenerative joint condition that occurs when the cartilage within the knee gradually wears down over time. As the cushioning between the joints becomes thinner, movement may become painful or stiff, especially during walking, climbing stairs, or prolonged activity.
Although ageing is one of the main risk factors, knee osteoarthritis can also be influenced by excess weight, previous injuries, repetitive strain on the joints, and family history.
Symptoms often develop gradually. Some people notice mild discomfort initially, while others may experience increasing pain, swelling, stiffness, or reduced flexibility that begins to interfere with mobility and daily activities.
Knee osteoarthritis may be considered severe when symptoms begin affecting mobility, independence, and overall quality of life.
For some individuals, pain becomes more persistent and no longer improves with rest, medication, physiotherapy, or lifestyle modifications. Stiffness may also become more noticeable, particularly after periods of inactivity or in the morning.
You should consider seeing an orthopaedic specialist if:
Knee pain is limiting daily activities
Walking, standing, or climbing stairs becomes difficult
Pain begins affecting sleep or quality of rest
Symptoms continue worsening despite ongoing treatment
You notice reduced mobility or instability in the knee
If knee osteoarthritis is left untreated, symptoms may gradually worsen over time. Pain can become more frequent, mobility may decline, and simple daily activities such as walking, climbing stairs, or standing for long periods may become increasingly difficult.
As the condition progresses, the knee joint may also become stiffer or less stable. In more advanced cases, changes in joint alignment or deformity can develop, further affecting movement and quality of life.
Many patients try to manage symptoms for years with medication, physiotherapy, or activity modification. However, when pain begins interfering with daily function despite ongoing treatment, it may be time to discuss longer-term treatment options with a specialist.
In many cases, symptoms are usually first managed with non-surgical treatments aimed at reducing pain, improving mobility, and slowing functional decline.
Some common concerns that we have heard among patients who are considering treatment options include, “am I too young for knee replacement?” or “is knee replacement safe for older adults?”. The decision to proceed with surgery is usually based on symptom severity, mobility limitations, response to conservative treatment, and overall quality of life rather than age alone.
An orthopaedic specialist can help assess your condition and determine whether knee replacement surgery is appropriate based on your individual needs and mobility goals.
Surgery is generally considered when symptoms continue affecting daily activities despite appropriate non-surgical management.
Maintaining a healthy weight can help reduce stress on the knee joints, especially during walking and weight-bearing activities. Many patients also benefit from switching to lower-impact exercises such as swimming, cycling, or guided strengthening exercises.
Simple adjustments, including supportive footwear and avoiding activities that aggravate symptoms, may also help improve comfort and mobility.
Pain relief and anti-inflammatory medications may be recommended to help manage symptoms, particularly during flare-ups. Your doctor will advise on suitable options based on your medical condition, lifestyle, and overall treatment goals.
Physiotherapy plays an important role in strengthening the muscles around the knee, improving joint stability, and maintaining mobility.
In some cases, injections such as corticosteroids or hyaluronic acid may also be considered to help manage pain and inflammation, depending on the severity of symptoms and individual response to treatment.
Robotic-assisted knee replacement is an advanced surgical approach used in the treatment of moderate to severe knee osteoarthritis. The procedure combines surgical expertise with robotic technology to support more precise implant positioning and alignment during surgery.
Unlike automated systems, the robotic system remains fully controlled by the surgeon throughout the procedure. Using detailed imaging and real-time guidance, the system helps surgeons plan and perform the surgery based on the patient’s individual anatomy.
For some patients, this more personalised approach may support improved joint function and recovery after surgery.
You may be asking “how do I know if I need knee replacement surgery?” or “at what stage of knee osteoarthritis is surgery usually recommended?”
Robotic knee replacement may be considered for patients with moderate to severe knee osteoarthritis, particularly when symptoms continue affecting mobility and quality of life despite ongoing non-surgical treatment.
It may also be recommended in situations where accurate implant alignment and surgical precision are important considerations during joint replacement.
A thorough clinical assessment by an orthopaedic surgeon is required to determine the most suitable treatment approach based on factors such as:
Severity of joint damage
Mobility limitations
Overall health
Lifestyle and activity level
Robotic-assisted knee replacement is designed to support greater precision during surgery, particularly in implant positioning and joint alignment.
By combining surgical planning with real-time intraoperative guidance, the technology allows surgeons to tailor the procedure more closely to the patient’s anatomy.
For some patients, this may help:
Support joint function after surgery
Reduce disruption to surrounding soft tissues
Contribute to a smoother rehabilitation process
Recovery experiences can still vary depending on overall health, rehabilitation, and the severity of the underlying joint condition.
Recovery after knee replacement surgery is gradual and focuses on restoring movement, strength, and confidence in the joint over time.
Most patients are encouraged to begin gentle movement and walking with support soon after surgery to help reduce stiffness and improve circulation. Physiotherapy also plays an important role throughout recovery, helping patients regain flexibility, muscle strength, balance, and mobility.
The pace of recovery differs from person to person. While some individuals return to daily routines relatively quickly, others may require a longer rehabilitation period depending on their condition and overall fitness before surgery.
Many patients notice progressive improvement over the weeks and months following rehabilitation and ongoing strengthening exercises.
Persistent knee pain should not be ignored, especially when it begins affecting mobility, sleep, work, or daily activities.
If symptoms of knee osteoarthritis continue despite medication, physiotherapy, or lifestyle modifications, book an appointment with an orthopaedic specialist to better understand the available treatment options.
At Prince Court Medical Centre, patients have access to personalised orthopaedic care, including advanced joint replacement procedures and robotic-assisted surgical options tailored to individual needs.
