Return-to-sport and performance outcomes after Achilles tendon rupture in National Hockey League players: A matched cohort study.
Article in Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA, 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
purposeAchilles tendon ruptures (ATRs) are uncommon but career-threatening injuries in elite athletes. Limited evidence exists regarding return-to-sport (RTS) and performance outcomes among National Hockey League (NHL) players following ATR. This study aimed to evaluate RTS rates and post-injury performance metrics in NHL players after ATR, using matched controls for comparison.
methodsNHL players who sustained an ATR between the 2000-2001 and 2024-2025 seasons were identified using publicly available databases and confirmed through independent sports news sources. Each player was matched 1:1 to a control based on position, age and pre-injury performance using a validated similarity algorithm. Demographic data and performance metrics, including points per game (PPG), games played (GP), average time on ice (ATOI) and a validated hockey-specific performance score (PS), were collected for two seasons before and after the injury or index date. RTS rates and pre- versus post-injury changes were assessed using paired t tests, with significance set at p < 0.05.
resultsA total of 20 NHL players met the inclusion criteria and were successfully matched to controls. The overall RTS rate was 87.0%, rising to 100% when accounting for players who retired from the NHL but continued playing professionally in other leagues. Although players with ATR (cases) demonstrated performance declines post-injury, no significant differences were observed in PS, PPG, ATOI or GP at any position, except for PS when all positions were analysed collectively. Similarly, control players experienced non-significant performance declines across all metrics post-index.
conclusionATR in NHL players is associated with high RTS rates and largely preserved performance metrics. While a modest decline in PS was observed, other key metrics remained stable compared to matched controls. These findings support favourable functional recovery and can inform post-injury expectations and management. LEVEL OF EVIDENCE: Level III.
