title: Medium-term and long-term outcomes of interventions for primary psoas tendinopathy.
abstract: OBJECTIVE
  To assess medium- and long-term outcomes of psoas tendinopathy to psoas tenotomy and image-guided steroid injections.
  
  
  METHODS
  This is a 14-year retrospective case-control study to identify the efficacy of psoas tenotomy and image-guided steroid injections.
  
  
  METHODS
  This study was undertaken in a secondary care setting.
  
  
  METHODS
  Patients with confirmed psoas tendinopathy were followed up by postal questionnaire, which included a nonarthritic hip score (NAHS) and a study patient satisfaction questionnaire.
  
  
  METHODS
  Patients underwent image-guided steroid injections. Depending on the analgesic or symptomatic relief, some patients proceeded to psoas tenotomy.
  
  
  METHODS
  Response to steroid injection. Pain relief and symptomatic relief after the surgery.
  
  
  RESULTS
  Twenty-three patients were reviewed with a 70% follow-up over a time of 49 months for surgery (range, 13-144 months) and 77 months for injection (range, 14-160 months). Eight patients had a lasting response to injection and required no further intervention, and 15 patients proceeded to psoas tenotomy using a medial Ludloff approach. The average NAHS scores after the surgery and injection were 66.15 and 76.08, respectively. Ten patients reported pain relief after their tenotomy, and 5 patients reported no change in pain. All 8 patients, who only underwent injection, reported lasting pain relief.
  
  
  CONCLUSIONS
  Local steroid injections can provide long-term relief for patients presenting with psoas tendinopathy. For those patients with only temporary relief from injection, psoas tenotomy can provide good long-term pain relief.
