Knee Injections: Platelet-Rich Plasma (PRP)

Platelet-Rich Plasma (PRP) Injection in Singapore

Not every musculoskeletal condition requires surgery. For patients with joint or tendon pain that has not responded to conservative treatment, there are non-surgical alternatives worth exploring.

At Alps Orthopaedic Centre, we offer platelet-rich plasma (PRP) injection, a minimally invasive treatment that uses your own blood to support tissue repair and reduce inflammation.

What Is Platelet-Rich Plasma (PRP) Injection

A platelet-rich plasma injection is an autologous treatment, meaning it is prepared from your own blood, which keeps the risk of allergic reaction or rejection low.

Platelets are tiny blood cells that play a central role in healing. They contain growth factors, which are proteins that signal your body to repair damaged tissue. In a PRP injection, these platelets are concentrated and delivered directly to the site of injury, giving your body a targeted boost where it needs it most.

It is commonly used in orthopaedic settings as part of a broader management plan for sports injuries and musculoskeletal conditions.

Conditions Platelet-Rich Plasma (PRP) Injections Can Treat

PRP injections are used across a range of musculoskeletal conditions. They may be considered when conservative treatments such as rest, physiotherapy, or anti-inflammatory medication have not produced sufficient improvement.

Conditions commonly treated with PRP include:

Knee pain: Cartilage degeneration in the knee joint
Tendinopathy: Includes rotator cuff tendinopathy, Achilles tendinopathy, and patellar tendinopathy
Lateral epicondylitis: Tennis elbow, pain on the outer side of the elbow
Medial epicondylitis: Golfer’s elbow, pain on the inner side of the elbow
Plantar fasciitis: Inflammation of tissue along the base of the foot
Hip pain: joint degeneration or soft tissue injury affecting the hip region
Ligament injuries: including partial tears that affect joint stability and movement control

Who Is a Suitable Candidate for Platelet-Rich Plasma (PRP) Injection

如果您符合以下条件，那么您可能适合……	A consultation will clarify if…
You have a tendon, joint, or soft tissue condition that has not responded to physiotherapy or conservative treatments	You have questions about whether PRP is appropriate given other medications or health conditions you are managing
You are looking for a non-surgical option before considering more invasive interventions	Your condition or medical history requires a more detailed assessment before PRP can be recommended
You have early-to-moderate osteoarthritis and are not yet at the stage where surgery is indicated	You are unsure whether your osteoarthritis is at an early-to-moderate stage

If the above describes you, PRP may provide the relief you’re looking for. Book an Orthopaedic Assessment to be sure.

How Is Platelet-Rich Plasma (PRP) Injection Performed

The process begins before the injection itself and takes around 30 to 45 minutes. Here’s what typically happens:

A small blood sample is drawn from your arm.
The sample is placed in a centrifuge, which spins at high speed to separate its components and concentrate the platelets.
The concentrated preparation, which contains a significantly higher platelet concentration than normal blood, is injected into the affected area.
Once delivered, the growth factors within the platelets promote tissue regeneration, reduce inflammation, and support the repair of damaged tendons, cartilage, or soft tissue.
The full effect develops gradually over several weeks following treatment.

Recovery After Platelet-Rich Plasma (PRP) Injection

Most patients return home the same day. Here is what to expect in the weeks that follow:

Some soreness or swelling at the injection site is normal and usually settles within a few days.
Strenuous activity and high-impact exercise are typically discouraged for one to two weeks.
Physiotherapy may be recommended to support rehabilitation. Your surgeon will advise if this applies to you.
Improvement is gradual. Many patients notice meaningful change between four and eight weeks after treatment.
Some patients benefit from more than one injection, spaced several weeks apart.

Benefits of Platelet-Rich Plasma (PRP) Injection

A PRP injection may offer several potential advantages for appropriate candidates:

Non-surgical: PRP is a minimally invasive procedure that does not require cuts, stitches, or general anaesthesia.
Uses your own biology: Because PRP is derived from your own blood, the risk of allergic reaction or rejection is low.
Targeted delivery: The growth factors are delivered directly to the site of injury rather than circulating through the whole body.
Reduces the need for ongoing medication: For some patients, PRP may reduce reliance on anti-inflammatory medications.
Short procedure time: The appointment is typically completed within an hour, and most patients return home the same day.

Risks and Side Effects of Platelet-Rich Plasma (PRP) Injection

PRP is generally well tolerated, but like any injection procedure, it carries some risks. The most commonly reported side effect is temporary soreness or discomfort at the injection site, which typically resolves within a few days.

Other possible side effects include:

Localised swelling or bruising at the injection site
A temporary increase in pain or stiffness in the first one to two weeks following injection, as part of the healing response
In rare cases, infection at the injection site

Serious complications are uncommon. Your doctor will discuss your full risk profile before proceeding.

Platelet-Rich Plasma (PRP) vs BMAC

PRP is one of several biologic injection options available for musculoskeletal conditions. Another one you may encounter is bone marrow aspirate concentrate (BMAC).

	PRP	BMAC
Source	Blood sample	Bone marrow (pelvis)
Key components	Platelets and growth factors	Stem cells, growth factors, and regenerative components
Procedure complexity	微创	More involved
Typically considered for	Broad range of tendon, joint, and soft tissue conditions	Complex or severe cases, such as significant cartilage damage or larger tendon tears
Evidence base	Most widely studied	Encouraging but largely lower-level evidence

Frequently Asked Questions About Platelet-Rich Plasma (PRP) Injection

Do PRP injections work?

For conditions such as knee pain and certain tendinopathies, multiple studies have shown meaningful improvements in pain and function compared to placebo or corticosteroid injections. Results vary depending on the condition, the area being treated, and individual biology.

How long will PRP treatment last?

Benefits may persist for 12 months or longer in many patients, though this varies between individuals and conditions. Some patients require repeat injections over time if symptoms return.

What are the side effects of PRP injections?

The most common side effect is temporary soreness or swelling at the injection site, which typically settles within a few days. A short-term pain flare in the first one to two weeks is possible and is considered part of the healing response. Serious complications are uncommon.
