COVID-19 Impact: 160,000 Joint Replacement Surgeries Disrupted

A new study has found that nearly nine months' worth of joint replacement surgeries—approximately 160,000 fewer operations—have been lost since the onset of the COVID-19 pandemic (). The research indicates that merely returning to pre-pandemic levels will not address the backlog, and even with rapid expansion, it could take many years, if not decades, to resolve this joint replacement crisis.

The study, published in The Bone & Joint Journal , looked in detail at the effect of the COVID-19 pandemic on the numbers of joint (hip, knee, shoulder, elbow, and ankle) replacement surgery carried out in England, Wales, and Northern Ireland.

Stiff Joints
Stiff joints are a major problem for the elderly, as the joints tend to wear-and-tear with advancing age, giving rise to joint pain and inflammation. There are many natural remedies, and medical treatments available for stiff joints.

COVID-19's Impact on Joint Replacement Surgeries

The researchers analysed National Joint Registry (NJR) data between January 2019 and December 2022 inclusive, which includes all NHS and privately funded hip, knee, shoulder, elbow, and ankle replacement operations.

The study compared the period including and after the pandemic (2020 to 2022 inclusive) to how many operations would have been performed had surgery continued at the same level as 2019.

The research team found by the end of 2022 almost three quarters of a year of planned operations - 71.6 percent of 2019 activity and 158,994 joint replacements - had been lost. This gap continues to increase and therefore the recovery from this deficit does not appear to have started. Knee, shoulder, and ankle surgery have been affected more severely than hip and elbow surgery.

Low Sodium Levels Tied to Increased Complications After Total Joint Replacement
Total joint arthroplasty patients with postoperative hyponatremia (low sodium levels) are more likely to experience a twofold increase in complications and other adverse outcomes.

The NHS has been more impacted than the private sector. By 2022, NHS activity was still only 73.2 percent of 2019 levels, whereas operations in the private sector had increased to 126.8 percent of 2019 levels. The private sector is now the main provider of joint replacements (53 percent in 2022) in England, Wales, and Northern Ireland.

Wales and Northern Ireland have been worse affected than England. Both countries recorded a backlog of more than a year’s worth of operations between 2020-2022; 136 percent of 2019 for Wales and 121.3 percent for Northern Ireland, whereas the deficit in England was 66.7 percent.

Urinary Catheter No Longer Needed for Joint Replacement Surgery
Joint replacement surgery can be performed safely without using a Foley urinary catheter, which for years has been used as a part of the standard practice for this type of surgery.

Jonathan French, Clinical Research Fellow in the Bristol Medical School: Translational Health Science (THS), and corresponding author, said: “Patients awaiting different types of joint replacement surgery in England, Wales, and Northern Ireland have been affected disproportionately, and recovery to pre-pandemic levels will be challenging. This will inevitably lead to many patients enduring unnecessary pain, disability and wider decline in mental and physical wellbeing.”

Michael Whitehouse, Professor of Trauma and Orthopaedics in the Bristol Medical School: THS, and senior clinical lead for the paper, explained: “If capacity was immediately expanded by five percent on top of 2019 levels it would take until 2040 to address the backlog. An immediate ten percent expansion, if possible, would still take until 2031 to catch up. This represents a severe challenge that is currently underestimated in planning and provision that requires prioritisation to mitigate the impact of debilitating joint related conditions on patients.”

Tim Wilton, Medical Director of the NJR, added: “The value of the volume data held by the NJR is that we can glean an accurate insight into the longer-term impact of COVID on the supply and demand and provision of surgical orthopaedic services. There is a clear need to plan and adjust service volumes based on this insight and research, so that patient waiting list numbers start to reduce across the different joints. These data, being based against the volume of cases done in 2019, are likely to be an underestimate of the catching-up required as the volume of cases was growing every year before 2019 rather than being static.”

Joint replacement surgery is a common and very effective surgical procedure used to treat a variety of musculoskeletal problems including osteoarthritis and acute trauma. Joint replacements are long-lasting, with over half of hip and knee replacements lasting over 25 years, and 90 percent of shoulder replacements lasting over ten years.
