Differences in health outcomes of orthopedic rehabilitation after hip or knee replacement: a prospective pilot study benchmarking 23 rehabilitation facilities using Patient-Reported Outcome Measures (PROMs).

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
backgroundPatient-reported outcome measures (PROMs) are increasingly used for benchmarking hip and knee arthroplasty, yet evidence on their feasibility for public reporting of short-term rehabilitation outcomes remains limited. International initiatives such as ICHOM recommend combining disease-specific and generic PROMs, but practical frameworks for risk-adjusted benchmarking in routine rehabilitation are scarce.
methodsIn this prospective pilot study, 23 German rehabilitation facilities contributed data on patients following total hip (THA) or knee arthroplasty (TKA). Patients completed the HOOS-PS or KOOS-PS and the VR-12 PCS/MCS at admission and discharge after a standardized three-week multimodal rehabilitation program. For primary analyses, 961 THA and 961 TKA cases with complete pre- and post-data on at least one PROM were available. Facility-level unadjusted change was quantified using Cohen's d

conclusionPROM-based, risk-adjusted benchmarking of short-term rehabilitation outcomes after hip and knee arthroplasty is feasible and meaningfully discriminative. The ProQI composite offers an interpretable, biopsychosocially grounded index for public reporting and quality management. Future work should enhance data completeness, refine risk adjustment, and validate the approach across broader cohorts and settings.
