Outcome of transtibial AperFix system in anterior cruciate ligament injuries.
Article in Indian journal of orthopaedics. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe anterior cruciate ligament (ACL) is one of the major stabilizing factor of the knee that resist anterior translation, valgus and varus forces. ACL is the most commonly ruptured ligament of the knee. The graft fixation to bone is considered to be the weakest link of the reconstruction. According to the parallel forces to the tibial drill hole and the quality of tibial metaphyseal bone is inferior to femoral bone stock, graft fixation to the tibia is more difficult to secure. AperFix system (Cayenne Medical, Inc., Scottsdale, Arizona, USA) which consists femoral and tibial component that includes bioinert polymer polyetheretherketone (PEEK) is one of the new choice for ACL reconstruction surgery. aim of this study was to assess the clinical outcomes and fixation durability of the AperFix (Cayenne Madical, Inc., Scottsdale, Arizona, USA) system and to determine the effect of patient's age in arthroscopic reconstruction of the anterior cruciate ligament. MATERIALS AND
methodsPatients with symptomatic anterior cruciate ligament rupture underwent arthroscopic reconstruction. Patients were evaluated in terms of range of motion (ROM) values; Lysholm, Cincinati and Tegner activity scales; laxity testing and complications. Femoral tunnel widening was assessed by computer tomography scans. Early postoperative and last followup radiographs were compared.
resultsFifty one patients were evaluated with mean followup of 29 months (range 25-34 months). Mean age at the surgery was 26.5 ± 7.2 years. Lysholm, Cincinati and Tegner activity scales were significantly higher from preoperative scores (Lysholm scores: Preoperative: 51.4 ± 17.2, postoperative: 88.6 ± 7.7 [P < 0.001]; Tegner activity scores: Preoperative 3.3 ± 1.38, postoperative: 5.3 ± 1.6 [P < 0.001]; Cincinati scores: Preoperative: 44.3 ± 17, postoperative: 81.3 ± 13.9 [P < 0.001]). The mean femoral tunnel diameter increased significantly from 9.94 ± 0.79 mm postoperatively to 10.79 ± 0.95 mm (P < 0.05). The mean ROM deficit (involved vs. contra knee) was -7.2 ± 16 (P < 0.001). There was no significant difference for knee score, ROM deficits (<30 years: -7.3 ± 15 and >30 years -7.06 ± 19) and femoral tunnel enlargement (<30 years: 0.83 ± 0.52 and >30 years 0.87 ± 0.43) of the patients with below and above 30 year. There was no significant difference for knee scores and femoral tunnel enlargement between patients with meniscal injuries and don't have meniscus lesions.
conclusionThe AperFix system gives satisfactory clinical and radiological results with low complication rate. However, long term clinical and radiological results are needed to decide the ideal anterior cruciate ligament reconstruction method.
