Clinical and psychosocial impact of limited mobility during the interstage period of two-stage revision arthroplasty for prosthetic joint infection: a state-of-the-art review.
Review in Journal of orthopaedic surgery and research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTwo-stage revision arthroplasty remains the gold-standard treatment in the United States for patients diagnosed with periprosthetic joint infection (PJI) of the hip and knee. However, during treatment, patients have an extended interstage period between prosthesis removal and reimplantation which is frequently characterized by substantial reductions in mobility, prolonged rehabilitation, and a high incidence of medical and psychosocial complications. This review examines the physical, psychological, and social effects of immobility during the interstage period.
methodsA comprehensive literature review was conducted to identify studies addressing mobility limitations, functional assessment tools, and associated outcomes in patients undergoing two-stage revision arthroplasty for PJI. Studies were included if they reported on clinical complications and psychosocial outcomes affected by the prolonged interstage period and mobility limitations.
resultsPatients undergoing two-stage revision often experience significant immobility lasting several months, which can be influenced by pain, soft-tissue compromise, and spacer type. Prolonged inactivity can contribute to muscle atrophy, joint stiffness, and impaired range of motion and is often associated with an increased risk of venous thromboembolism, pressure injuries, and bleeding complications related to extended thromboprophylaxis use. Psychologically, patients frequently report heightened anxiety and depression during the interstage period, compounded by uncertainty regarding infection eradication. Socially, patients have restricted independence, are dependent on caregivers, and have occupational disruption that further diminishes their overall quality of life (QoL). Current studies demonstrate wide variability in how mobility is assessed, hindering cross-study comparison and limiting targeted rehabilitation strategies.
conclusionsThe interstage period of two-stage revision arthroplasty is a critical, yet understudied phase marked by significant physical, psychological, and social challenges that are not fully captured by traditional orthopedic patient-reported outcome measures . Standardized measurement of mobility is needed to assess the impact of limited mobility during the interstage period. Also, novel treatment approaches that shorten or eliminate the interstage period have the potential to mitigate complications, enhance functional recovery, and improve overall QoL for patients undergoing staged management of PJI.
