How hyaluronic acid injections can accelerate arthroscopy recovery and reduce pain
What is arthroscopy?
Arthroscopy is a minimally invasive surgery to diagnose and treat joint problems. During the procedure, an arthroscope (a narrow endoscopic camera) is inserted into the joint via a small incision, allowing the doctor to visualise inside of the joint. An additional small incision is made for the surgical instruments to access the joint. Arthroscopy can be carried out on any joint, but is mostly used for the knee, shoulder, elbow, wrist, ankle, foot, and hip. Common arthroscopic procedures include reconstruction of the anterior cruciate ligament, repair of meniscus tears and rotator cuff tears, and debridement (i.e. clearing debris) of the joint.
How can hyaluronic acid injection improve post-operative recovery?
To provide a better view of the joint during arthroscopy, the joint is filled with a sterile saline irrigation solution. This solution displaces the synovial fluid — and its major component, Additionally, there is a loss of the masking effect that hyaluronic acid usually has on pain receptors.1
Following the operation, patients commonly experience pain, swelling and impaired joint mobility due to the lack of synovial fluid.2 Injecting hyaluronic acid into the joint can improve post-operative recovery, reducing the likelihood and severity of these post-operative complications.
Injection of hyaluronic acid following arthroscopy has been proven to:
- Reduce post-operative pain and swelling3–8
- Improve joint function and mobility4,9
- Reduce post-operative painkiller consumption4,7,8
- Reduce time to discharge from hospital7,8
- Accelerate the return to work or sport after surgery3,10
What is the average recovery time from arthroscopic surgery?
Due to the small incisions required for arthroscopy, the recovery time is significantly shorter than for open surgery. Depending on the joint, whether any joint repair was performed, and the patient’s state of health, recovery can vary from 1 week to several months. Patients undergoing knee arthroscopy can usually expect to return to normal activities after 4–6 weeks, and for rotator cuff arthroscopy this may take 6–8 weeks. Return to sporting activities may take 3–6 months.
How is pain managed following arthroscopy?
Pain in the joint following an arthroscopy is normal, and patients are prescribed painkillers to manage this. Patients are also advised to apply ice to reduce the swelling and pain in the first day following surgery.
Oral nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen are often prescribed for post-arthroscopy pain management. Most patients have no problems with taking oral NSAIDs over a short period, but some people may suffer from side-effects if they already have cardiovascular or gut conditions. Due to the risk of side-effects, oral NSAIDs are not recommended for long-term use.11
Opioids (sometimes called narcotics) may be prescribed for managing more severe pain, but for most patients this level of pain relief is not necessary.12 Side effects of opioids include sleepiness, constipation, and nausea, and they come with a risk of addiction, so they are not recommended as first option.13
Corticosteroid and anaesthetic injections into the joint have previously been used for pain management following arthroscopy but are no longer recommended due to the damaging effect they can have on the cartilage.14–17
Injection of hyaluronic acid into the joint cavity at the end of the arthroscopy procedure is an effective approach to reduce post-operative pain and painkiller use following arthroscopy.4,7,8
Are there any side effects of hyaluronic acid injections?
Hyaluronic acid is a molecule that is naturally produced by the human body, and is present in the skin, the joints and the tendons. The injection of hyaluronic acid following arthroscopy is well tolerated and safe, and no adverse events have been reported. Hyaluronic acid can safely be used in patients with comorbidities.
