Alternatives to Knee Replacement

If you have knee pain, knee replacement surgery should always be the final option. Although it is a common and safe procedure, a knee replacement is major surgery which has associated risks and a long recovery period. Before considering a knee replacement it is advisable to discuss non-surgical treatments with your doctor.

What is joint cartilage damage?

The ends of the knee bones are normally covered in shiny white cartilage called joint cartilage that helps to keep the joint movement smooth. Arthritis is termed wear and tear to the cartilage and surgeons can grade the degree of cartilage destruction as:

Grade 0 – cartilage is normal and intact

Grade 1 – some softening of the cartilage

Grade 2 – partial thickness (less than 50%) defect or minor tears in the cartilage surface

Grade 3 – deeper defect (more than 50%)

Grade 4 – full thickness cartilage loss with underlying bone exposure

What is a knee replacement?

In a standard knee replacement the aim is to ‘resurface’ the end of the bone. Small amounts of bone and remaining joint suface cartilage are removed and resurfaced with metal and plastic. Parts of the femur and tibia bone are cut and resurfaced with metal, inbetween a piece of plastic is used. If the kneecap is also degenerated, this can also be resurfaced.

When is a knee replacement considered?

It is important that all patients are given all information regarding other options and that they understand what the indications are for knee replacement surgery. More conservative options can be attempted first before choosing a total knee replacement, which really is the last option. Indictations for knee replacement include:


This is a primary factor when considering knee replacement surgery. Simply, how severe and how much it is interfering with day-to-day activity. This includes night pain which is a common feature of arthritis. 

A way to measure pain, subjectively, is asking patients to rank their pain on a scale of 0-100, we call this the Visual Analogue System (VAS).


Arthritis causes inflammation which in turn causes swelling. An increased amount of fluid in the knee can often accumulate at the back of the joint which can form a Baker’s cyst, which can be painful and tender. People considering knee replacement may experience this.


Besides functional stiffness from worn joint surface and accumulated fluid. Arthritis can cause patients to hold the knee in a slightly bent position to avoid pain of the worn joint surfaces touching each other. This can lead to the flexion of the knee becoming fixed and being unable to straighten the leg. 


As pain, swelling and stiffness increase, it is common that people suffering with arthritis will become less active and the muscles around the knee start to waste. The quadriceps (front of the thigh) are essential in the stability of the joint and in standing up. 


Older patients tend to find more success with knee replacements as they are less active. Compared to younger patients, once they recover they hope to return to an active lifestyle which decreases the life expectancy of the joint.

What are the typical outcomes of a knee replacement?

Recent studies have shown us that there is a significant number of patients who are unhappy with their knee replacement. This is measured by standardised, objective and subjective questions providing knee function scores and quality-of-life scores. 

Good outcomes

10% of patients will have a fantastic result with zero pain. 70% of patients will feel significantly better but are partly dissatisfied because the knee doesn’t feel completely normal (residual swelling and pain). 

Bad outcomes

20% of patients will have a bad result and a small portion having worse pain than before. They may complain of instability and clunking as the knee is straightened. 

Am I too young for a knee replacement?

Many patients are told they have bad arthritis but are too young for joint replacement surgery. Mainly because younger patients return to a more active lifestyle than older patients and decrease the life expectancy of the knee replacement. In this case, lots of non-operative and operative alternatives exist and may be suitable.

What are the non-operative alternatives?

There are a number of alternative interventions that might be able to alleviate symptoms of joint cartilage damage. 

This day case treatment is exclusively offered to our patients. It uses pioneering technology using your body’s own adipose (fat) cells to treat pain and inflammation with MFAT Injections. Injections using MFAT Injections are minimally invasive and are carried out under ultrasound guidance. Altogether the procedure takes about an hour to perform with a minimal recovery time. As well as being a potential alternative to surgery, MFAT Injections can also aid post-surgery recovery.

BMAC Injections harness the natural healing abilities of your own mesenchymal stem cells, found in the bone marrow, to regenerate and reconstruct the musculoskeletal system by replacing cells and tissues damaged by degenerative diseases or trauma. BMAC Injections treat pain and inflammation by accelerating healing through the assistance of biological growth factors. This minimally invasive, day-case procedure is done under x-ray guidance and has a minimal recovery time. Our innovative BMAC Injections offer an alternative treatment plan to traditional invasive surgery.

This is an effective and well-researched procedure that’s a potential alternative to surgery. It takes advantage of the blood’s natural healing properties to reduce pain and improve joint function. It uses a specially concentrated dosage of platelets prepared from your own blood to repair damaged cartilage, tendons, ligaments, muscle and bone. Treatment is administered via an injection and depending on the injury two to six injections may be required, performed at weekly intervals. Patients usually see their symptoms improve within four to six weeks of having the injections. PRP is a safe treatment option which, because your own blood is used, carries no risk of allergic reaction. Read more clinical evidence supporting PRP here.

The nSTRIDE APS injection treatment is designed to alleviate pain. It is an autologous solution meaning that it is prepared from a sample of your own blood. Within osteoarthritic joints, inflammatory (swelling) proteins are present in a much greater concentration than anti-inflammatory proteins, causing a gradual breakdown of the cartilage. nSTRIDE APS injections contain a solution of concentrated anti-inflammatory proteins which restore the balance between inflammatory and anti-inflammatory proteins by preventing the activity/function of inflammatory proteins. This results in the reduction of inflammation and prevents any further deterioration of cartilage. nSTRIDE APS injections also contain anabolic proteins which stimulate the growth of cartilage and aids in the reduction and potential reversal of progression of osteoarthritis.

We offer steroid injections and the latest Viscoelastic Supplements using OESTINEL® PLUS (a long lasting and effective pain relieving injection) and CINGAL® (a unique and highly effective pain relieving injection that combines hyaluronic acid and a fast acting steroid. Find out more.

Orthopaedic braces stabilize, support and correct injuries or abnormal alignment through the process of rehabilitation and recovery. They are used in osteoarthritic care, injury rehabilitation/prevention and post-operative care. Find out more.


Weight loss and exercise as a first step. Losing weight puts less strain on your knee and exercise, such as swimming or cycling, can improve the strength and flexibility of your knee as well as help you lose weight. Being inactive can lead to a stiffer joint as weight tends to go up and muscle lost. A stiffer joint can make arthritic symptoms worse and makes surgery less successful compared to a joint that moves well. A physiotherapist can design a programme to help strengthen the key muscles around your knee and ultimately reduce pain. 

What are the surgical alternatives?

Partial knee replacement

A partial knee replacement is where only one area of the knee joint is resurfaced. The knee has three different areas where the bones move against one another (medial, lateral and patellofemoral), these are called compartments. In a partial or unicompartmental knee replacement the surfaces of the worn compartment are replaced in a similar way with metal and plastic. The advantages of a partial compared to a total knee replacement is that:


An arthroscopy is a type of keyhole surgery used to diagnose and treat certain conditions. It can be advised to patients with a knee injury to remove bone fragments, pieces of torn meniscus or damaged cartilage. 


Misalignment of the knee can cause certain areas of the joint surface to become arthritic. Ostetomy is a realignment procedure that involves cutting a wedge into one or both of the bones either side of the knee and altering the alignment of the leg. This can be highly effective in relieving symptoms and the knee joint is preserved.

Jorja Healthcare Regenerative Treatments’ Professor Adrian Wilson is a leading surgeon in osteotomy and can offer it in combination with other regenerative treatments to his patients.

Knee joint distraction

Knee joint distraction is a relatively new procedure and is increasingly investigated. Joint distraction requires an external frame to be fixed in the femur and tibia. This allows the knee joint to gradually seperate for several weeks. The aim being to reduce menchanical stress on the joint surface, preventing further wear and tear and initiating tissue repair. Find out more.
