About this release

This release by Public Health Scotland presents data on the number of arthroplasty (joint replacement) operations in Scotland between 2001 and 2020 and on the frequency of complications such as infection or revision surgery following hip and knee replacements.

An accompanying release is available as an e-publication (external website).

Main points

  • The impact of the pandemic on arthroplasty operations was clear with 15,864 first (primary) hip or knee replacements performed in Scotland in 2019 compared to 7,233 in 2020.

  • The percentage who died within 90 days of revision of a hip replacement reduced from 1.7% in 2019 to 0.3% in 2020. This is more in line with previous years.
  • The rates of major orthopaedic complications – dislocation, infection and deep vein thrombosis (DVT) or pulmonary embolism (PE) within one year – are all less than 8 per 1,000 procedures.

Background

The Scottish Arthroplasty Project remains one of the oldest arthroplasty registry organisations in the world. It is a member of the International Society of Arthroplasty Registries and, in comparison to organisations in many other countries, it is able to produce good quality data for a very modest outlay. Its principal aim is to provide quality assurance and adverse outcome monitoring of major joint replacement surgery in Scotland.

The Scottish Arthroplasty Project analyses hospital inpatient information to monitor the number of complications following hip and knee replacements in Scotland, and to ensure that surgeons performing these operations do not have a higher than expected complication rate. Where there is a higher than expected number of complications following operations performed by a particular surgeon, the surgeon is notified and asked to investigate the reasons for the increased rate in complications and to develop an action plan to reduce their recurrence.
