The Role of Acupuncture in Hemiarthroplasty Recovery

Acupuncture is a traditional Chinese medicine practice that involves inserting thin needles into specific points on the body. It has been used for centuries to treat various health conditions and promote overall well-being. In recent years, acupuncture has gained attention for its potential role in aiding recovery after hemiarthroplasty, a surgical procedure commonly performed to treat hip fractures in older adults. This article explores the role of acupuncture in hemiarthroplasty recovery, examining its potential benefits, mechanisms of action, and evidence from research studies.

The Basics of Hemiarthroplasty

Hemiarthroplasty is a surgical procedure that involves replacing the femoral head (the ball-shaped top of the thigh bone) with a prosthetic implant. It is commonly performed in older adults who have sustained a hip fracture, particularly those with displaced fractures or pre-existing hip arthritis. The procedure aims to relieve pain, improve mobility, and restore function in the affected hip joint.

During hemiarthroplasty, the damaged femoral head is removed, and a prosthetic implant is inserted into the femoral neck. The implant is typically made of metal or ceramic and is designed to mimic the shape and function of the natural femoral head. The prosthetic implant is secured in place with or without cement, depending on the patient’s specific needs and the surgeon’s preference.

The Role of Acupuncture in Pain Management

Pain management is a crucial aspect of the recovery process after hemiarthroplasty. Acupuncture has long been recognized for its analgesic (pain-relieving) properties and is commonly used as an adjunct therapy for various types of pain. When it comes to hemiarthroplasty recovery, acupuncture may offer several benefits in pain management:

  • Reduced reliance on pain medications: Acupuncture can help reduce the need for opioid pain medications, which are associated with various side effects and risks, including addiction and respiratory depression.
  • Improved pain control: Research suggests that acupuncture may help alleviate both acute and chronic pain by stimulating the release of endorphins, the body’s natural pain-relieving chemicals.
  • Enhanced overall well-being: Acupuncture is known to promote relaxation and reduce stress, which can contribute to improved pain management and overall well-being during the recovery period.

Several studies have investigated the effectiveness of acupuncture in pain management after orthopedic surgeries, including hip replacements. A systematic review and meta-analysis published in the Journal of Orthopaedic Surgery and Research in 2019 analyzed the findings of 12 randomized controlled trials involving a total of 1,026 patients. The review concluded that acupuncture significantly reduced postoperative pain intensity and decreased the need for additional pain medications compared to control groups.

The Potential Mechanisms of Action

The exact mechanisms through which acupuncture exerts its effects on pain relief are not fully understood. However, several theories have been proposed to explain its potential mechanisms of action:

  • Gate control theory: According to this theory, acupuncture stimulates sensory nerves, which can interfere with the transmission of pain signals to the brain. This mechanism is thought to involve the activation of inhibitory interneurons in the spinal cord, effectively “closing the gate” to pain signals.
  • Endorphin release: Acupuncture has been shown to stimulate the release of endorphins, which are natural pain-relieving chemicals produced by the body. Endorphins bind to opioid receptors in the brain and spinal cord, reducing the perception of pain.
  • Anti-inflammatory effects: Acupuncture may have anti-inflammatory effects, which can help reduce pain and swelling in the affected area. It is believed to modulate the release of various inflammatory mediators and promote tissue healing.

While these theories provide some insight into the potential mechanisms of action, further research is needed to fully understand how acupuncture works and its specific effects on pain relief in the context of hemiarthroplasty recovery.

Evidence from Research Studies

Several research studies have investigated the role of acupuncture in hemiarthroplasty recovery. While the available evidence is limited, the findings suggest that acupuncture may have positive effects on various aspects of the recovery process:

  • Pain relief: A randomized controlled trial published in the Journal of Pain Research in 2018 compared the effects of acupuncture and sham acupuncture on pain intensity and functional outcomes in patients undergoing hemiarthroplasty. The study found that acupuncture significantly reduced pain intensity and improved functional outcomes compared to sham acupuncture.
  • Range of motion and mobility: Another study published in the Journal of Integrative Medicine in 2019 investigated the effects of acupuncture on range of motion and mobility in patients after hemiarthroplasty. The results showed that acupuncture significantly improved hip joint range of motion and mobility compared to a control group.
  • Quality of life: A systematic review and meta-analysis published in the journal Pain Medicine in 2020 examined the effects of acupuncture on quality of life in patients with hip fractures. The review included six randomized controlled trials and concluded that acupuncture had a positive impact on various aspects of quality of life, including physical function, pain, and mental well-being.

While these studies provide promising evidence, it is important to note that more high-quality research is needed to establish the effectiveness of acupuncture in hemiarthroplasty recovery. Larger randomized controlled trials with rigorous methodology are necessary to confirm the findings and determine the optimal acupuncture protocols for this specific population.


Acupuncture may play a valuable role in the recovery process after hemiarthroplasty. Its potential benefits in pain management, range of motion improvement, and overall well-being make it a promising adjunct therapy for patients undergoing this surgical procedure. While the evidence from research studies is still limited, the available findings suggest that acupuncture can have positive effects on various aspects of hemiarthroplasty recovery. Further research is needed to fully understand the mechanisms of action and establish the optimal acupuncture protocols for this specific population. Nonetheless, acupuncture offers a non-invasive and potentially effective option for enhancing the recovery process and improving outcomes after hemiarthroplasty.
