Rate of functional recovery after hip arthroscopy for femoroacetabular impingement syndrome: patient-reported outcomes at three, six, and twelve months.
Article in International orthopaedics, 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
purposeTo characterise recovery trajectories across nine patient-reported outcomes (PROs) during the first twelve months after hip arthroscopy for femoroacetabular impingement syndrome (FAIS), and to determine whether six-month assessment serves as a representative endpoint.
methodsRetrospective analysis of a prospective database (2007-2025). Patients undergoing primary hip arthroscopy for FAIS completed nine PROs pre-operatively and at three, six, and twelve months. Linear mixed-effects models adjusted for age, BMI, sex, morphology, cartilage grade, and labral treatment were the primary analysis; Holm correction controlled the family-wise error rate. MCID and PASS achievement with 95% Wilson CIs were secondary outcomes.
resultsIncluded were 1,095 hips (44.2% CAM; 52.9% combined; mean age 38.2 ± 12.7 years; 63.3% male). The largest gains occurred at three months (mHHS: Δ + 14.6, 95% CI + 12.8 to + 16.5; iHOT-33: Δ + 20.9, + 18.2 to + 23.5; both p < 0.001). Further improvement occurred through six months. After Holm correction, no instrument showed statistically significant change from six to twelve months (all p-adj > 0.05; effect sizes d = 0.05-0.12). MCID achievement rose from three to six months (mHHS: 57.9% to 69.4%; HOS Sport: 52.9% to 68.2%), with minimal further gain at twelve months.
conclusionRecovery follows a biphasic pattern: the largest gains occur within three months, with further improvement through six months. After Holm correction, no PRO changed significantly from six to twelve months. Six-month assessment is a pragmatic endpoint for pain, daily-living function, and overall hip scores. HOS Sport and SF-36 PCS warrant twelve-month evaluation in athletes and studies using these as primary endpoints.
