Patellofemoral Joint (PFJ) Arthroplasty in Young Patients: Mid-term Results and Functional Outcomes.

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
Purpose Isolated patellofemoral arthritis is a well-recognized variant of knee osteoarthritis. The cause of isolated patellofemoral arthritis can be traumatic, secondary to malalignment, degenerative, or idiopathic. This study aims to evaluate whether the results of our third-generation patellofemoral arthroplasty (PFA) support its continued use as a viable treatment option for isolated patellofemoral arthritis. Methods A retrospective cohort study was conducted using the electronic NHS trust database to identify all patients who underwent PFA between September 2008 and April 2014. Each patient was subsequently reviewed at our outpatient clinic, where they completed a series of standardized questionnaires to assess treatment outcomes. These included the Short Form 12v2, the Forgotten Joint Score (FJS), the Kujala Score, and the Knee Injury and Osteoarthritis Outcome Score (KOOS). A total of 44 patellofemoral joints (PFJs) were included in the study. Results Four patients required revision surgery to convert their PFJ replacement to a total knee replacement. Additionally, three patients underwent arthroscopy for the management of patella maltracking. When asked about their satisfaction and whether they would choose to undergo the same surgery again, only seven patients indicated that they would opt for the procedure again. The FJS revealed that the majority of patients (85%) reported being rarely or never aware of their artificial joint in daily activities. The average Kujala score was found to be 4, reflecting moderate discomfort or dysfunction levels. The KOOS indicated that most patients experienced mild to moderate symptoms, with occasional bouts of pain and moderate stiffness. Importantly, the KOOS findings also suggested that the patients' daily activities were not severely impacted. Conclusion PFJ arthroplasty can yield positive outcomes for younger patients who suffer from isolated patellofemoral arthritis. However, achieving successful results is heavily influenced by the careful and appropriate selection of patients rather than the choice of the implant itself.
