Rehabilitation and Return to Play Protocols Following Osteochondral Autograft and Allograft Transplantation for Knee Chondral Lesions in Athletic Populations.
Review in Current reviews in musculoskeletal medicine, 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
purpose of reviewOsteochondral autograft transplantation (OATS) and osteochondral allograft transplantation (OCA) are established cartilage restoration procedures for symptomatic chondral and osteochondral defects of the knee in athletes. Postoperative rehabilitation is central to graft healing and incorporation, functional recovery, and safe return to play (RTP). This review synthesizes contemporary evidence on rehabilitation after OATS and OCA, including weight-bearing progression, bracing, range of motion, blood flow restriction training, and RTP criteria. RECENT
findingsSystematic reviews and survey studies report substantial variability in rehabilitation protocols, including weight-bearing timelines, bracing duration, continuous passive motion utilization, and RTP criteria. Few published protocols incorporate objective functional testing to guide RTP. Criteria-based frameworks that individualize progression by graft type, lesion location, and functional milestones are increasingly advocated, although supporting evidence remains limited. Blood flow restriction training may help preserve strength early after surgery, but data specific to OATS and OCA remain sparse. Return to play is commonly reported after both procedures, with earlier timelines more frequently reported after OATS than OCA. Rehabilitation after OATS and OCA requires balancing early graft protection with progressive restoration of motion, strength, and sport-specific capacity. Current evidence demonstrates wide protocol heterogeneity and continued reliance on time-based milestones, with underuse of objective RTP criteria. Standardized, criteria-driven pathways and multidisciplinary decision-making may improve consistency and optimize outcomes in athletic populations.
