Safety and feasibility of locoregional platelet-rich plasma injection for iliopsoas impingement after total hip arthroplasty: A phase 1 prospective observational study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Although numerous studies have reported outcomes with various conservative approaches for the iliopsoas impingement after total hip arthroplasty (THA), reports on the use of locoregional autologous platelet rich plasma (PRP) injections for the iliopsoas impingement after THA are lacking. This phase 1 study therefore aimed to investigate the safety and feasibility of locoregional PRP injection for iliopsoas impingement after THA. Materials and methods: Patients diagnosed with iliopsoas impingement after THA who met the criteria for participation (symptoms persisting for more than 3 months, aged 20 years or older, and unable to receive non-steroidal analgesic or anti-inflammatory drugs) were eligible to participate in this clinical study. The primary endpoint was observed adverse events including procedure-related pain, and the secondary endpoints included pain and functionality of the hip joint, that were assessed using the Western Ontario and McMaster Universities Arthritis Index, Japanese Hip Disease Evaluation Questionnaire, and Forgotten Joint Score-12. Results: Three patients were screened for eligibility, and 3 patients were finally included in this study. Two participants (patients 1 and 2; aged 66 and 65 years, respectively) were female. The third participant (patient 3; age 73 years) was male. All patients experienced adverse events; however, none were found to be serious. None of the patients experienced any infections, or intra- or post-operative symptoms of nerve damage, or subcutaneous haemorrhage owing to the administration of locoregional PRP. Although patient 2 showed almost complete resolution of the symptom, patient 1 and 3 demonstrated persistent groin pain after the injection. Conclusion: We demonstrated the results of preliminary phase 1 prospective observational clinical study that administration of locoregional PRP injections for iliopsoas impingement following THA is both, safe and feasible.
