Background: Radiographic tibiofemoral (TF) osteoarthritis (OA) is common in patients after anterior cruciate ligament (ACL) reconstruction at long-term follow-up. The association between radiographic OA and patient-reported outcomes has not been thoroughly investigated. Purpose: To determine the association between radiographic TF OA and patient-reported outcome measure (PROM) scores at 16 years after ACL reconstruction. Study Design: Case-control study; Level of evidence, 3. Methods: This study was based on 2 randomized controlled studies comprising 193 patients who underwent unilateral ACL reconstruction. A long-term follow-up was carried out at 16.4 ± 1.7 years after surgery and included a radiographic examination of the knee and recording of PROM scores. Correlation analyses were performed between radiographic OA (Kellgren-Lawrence [K-L], Ahlbäck, and cumulative Fairbank grades) and the PROMs of the International Knee Documentation Committee (IKDC) subjective knee form, Lysholm score, and Tegner activity scale. A linear univariable regression model was used to assess how the IKDC score differed with each grade of radiographic OA. Results: Of 193 patients at baseline, 147 attended the long-term follow-up. At long-term follow-up, 44.2% of the patients had a K-L grade of ≥2 in the injured leg, compared with 6.8% in the uninjured leg. The mean IKDC score at follow-up was 71.2 ± 19.9. Higher grades of radiographic OA were significantly correlated with lower IKDC and Lysholm scores ( r = –0.36 to –0.22). Patients with a K-L grade of 3 to 4 had significantly lower IKDC scores compared with patients without radiographic OA (K-L grade 0-1). Adjusted beta values were –15.7 (95% CI, –27.5 to –4.0; P = .0093; R 2 = 0.09) for K-L grade 3 and –25.2 (95% CI, –41.7 to –8.6; P = .0033; R 2 = 0.09) for K-L grade 4. Conclusion: There was a poor but significant correlation between radiographic TF OA and more knee-related limitations, as measured by the IKDC form and the Lysholm score. Patients with high grades of radiographic TF OA (K-L grade 3-4) had a statistically significant decrease in IKDC scores compared with patients without radiographic TF OA at 16 years after ACL reconstruction. No associations were found between radiographic TF OA and the Tegner activity level.

Background: The Knee injury and Osteoarthritis Outcome Score (KOOS) has demonstrated inferior psychometric properties when compared with the International Knee Documentation Committee (IKDC) subjective knee form when assessing outcomes after anterior cruciate ligament (ACL) reconstruction. The KOOS, Joint Replacement (KOOS, JR) is a validated short-form instrument to assess patient-reported outcomes (PROs) after knee arthroplasty, and the purpose of this study was to determine if augmenting the KOOS, JR with additional KOOS items would allow for the creation of a short-form KOOS-based global knee score for patients undergoing ACL reconstruction, with psychometric properties similar to those of the IKDC. Hypothesis: An augmented version of the KOOS, JR could be created that would demonstrate convergent validity with the IKDC but avoid the ceiling effects and limitations previously noted with several of the KOOS subscales. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Based on preoperative and 2-year postoperative responses to the KOOS questionnaires from a sample of 1904 patients undergoing ACL reconstruction, an aggregate score combining the KOOS, JR and the 4 KOOS Quality of Life subscale questions, termed the KOOSglobal, was developed. Psychometric properties of the KOOSglobal were then compared with those of the IKDC subjective score. Convergent validity between the KOOSglobal and IKDC was assessed with a Spearman correlation (ρ). Responsiveness of the 2 instruments was assessed by calculating the pre- to postoperative effect size and relative efficiency. Finally, the presence of a preoperative floor or postoperative ceiling effect was defined with the threshold of 15% of patients reporting either the worst possible (0 for KOOSglobal and IKDC) or the best possible (100 for KOOSglobal and IKDC) scores, respectively. Results: The newly developed KOOSglobal was responsive after ACL reconstruction and demonstrated convergent validity with the IKDC. The KOOSglobal significantly correlated with the IKDC scores (ρ = 0.91, P < .001), explained 83% of the variability in IKDC scores, and was similarly responsive (relative efficiency = 0.63). While there was a higher rate of perfect postoperative scores with the KOOSglobal (213 of 1904, 11%) than with the IKDC (6%), the KOOSglobal was still below the 15% ceiling effect threshold. Conclusion: The large ceiling effects limit the ability to use several of the KOOS subscales with the younger, more active ACL population. However, by creating an aggregate score from the KOOS, JR and 4 KOOS Quality of Life subscale questions, the 11-item KOOSglobal offers a responsive PRO tool after ACL reconstruction that converges with the information captured with the IKDC. Also, by offering the ability to calculate multiple scores from a single questionnaire, the KOOSglobal may provide the orthopaedic community a single PRO platform to be used across knee-related subspecialties.

Subjective Outcomes

Background: Graft choice for ACL reconstruction in patients under 18 years old remains controversial. BTB autograft has long been considered for young athletes who are at or near skeletal maturity. Quadriceps autograft has emerged as an alternative graft choice in the young patient population. However, there remains a paucity of comparative outcomes. Hypothesis/Purpose: Our purpose is to compare subjective outcomes and complications of ACL reconstruction in patients under 18 years old using either BTB or quadriceps autograft. Our hypothesis is that there will be no difference in subjective outcome or complication between groups. Methods: Following IRB approval, retrospective review of prospectively collected data identified consecutive cohorts of patients under 18 years old undergoing ACL reconstruction with either BTB or quadriceps autograft. Surgery was performed by a single sports fellowship trained surgeon between 2011-2019. Patients undergoing concomitant osteotomies, cartilage restoration, and other ligament reconstruction procedures were excluded. Pre- and post-surgical patient reported outcomes (PROs) including IKDC, KOOS, PROMIS, SANE, Tegner, and Marx were compared between groups. Complications requiring re-operation (i.e., infection, stiffness, reconstruction failure) were recorded. Results were analyzed statistically. Results: 71 patients met inclusion criteria. There were 41 BTB and 30 quadriceps autografts. Mean age was 16.5 years in the BTB group and 14.5 in the quadriceps group (p=0.0000006). 27 of 41 (66%) BTB and 13 of 30 (43%) quadriceps were female. There were no significant differences in PROs between groups. At minimum 6-month follow-up (range 6-25.7 months), patients in both quadriceps and BTB autograft cohorts reported statistically significant improvements in IKDC scores (31.10%, p=0.0009; 34.25%, p=0.00000008), all KOOS domains, SANE (41.80%, p=0.0000006; 42.42%, p=0.000000002), and Tegner scores (2.99%, p=0.0002; 3.35%, p=0.000004). Post-operative PROs were not significantly different between groups (p>0.05). Complications were low and not significant between groups. Both quadriceps and BTB autograft cohorts required 3 post-operative re-operations (10% and 7%, p=0.7), each group including 2 revision reconstructions (7% and 5%, p=0.8) and 1 procedure for stiffness (3% and 2%, p=0.8). Conclusion: For ACL reconstruction in patients under 18 years old, both BTB and quadriceps autografts demonstrated significant subjective improvements and low rates of complications requiring re-operation. Quadriceps autograft appears to be a safe and effective alternative to BTB autograft in this challenging patient population. [Table: see text][Table: see text]

Physeal Sparing

Objectives: Physeal-sparing techniques for anterior cruciate ligament (ACL) reconstruction have previously been described as safe treatment for adolescent ACL tears in patients with open physes, however few studies to date have reported on return-to-sport or patient reported outcome scores for this specific patient population. This study examined patient reported outcomes in children who underwent a physeal-sparing ACL reconstruction with a minimum of two-year follow-up. Methods: Surgical logs of ACLR performed at a single pediatric/adolescent sports medicine center from 2011 to 2016 were reviewed. Patients with open physes who had ACLR with a hybrid physeal sparing or all-epiphyseal technique were identified. Patients were treated by one of two pediatric sports trained orthopedic surgeons. Their demographics, operative reports, rehabilitative course, time to return-to-play, and post-operative course were retrospectively reviewed. Prospective patient reported outcomes scores, ACL-Return to Sport after Injury (ACL-RSI) and International Knee Documentation Committee (IKDC) or Pediatric IKDC (Pedi-IKDC) and return to sport questionnaire including pre-injury primary sport and competition level, ability to return to pre-injury level of competition following ACLR and subsequent ACL injury were collected. Results: There were 49 patients who met inclusion criteria. Prospectively collected data was obtained for 25 patients at an average of 4.6 (range 2.1-8.0) years following surgery. The average chronological age of patients at time of surgery was 12.8 ± 1.4 years with an average bone age of 13.5 ± 1.3 years. At mid-term follow-up, the average chronological age was 17.2 ± 2.0 years. Average Pedi-IKDC or IKDC score was 94.2 ± 9.2 and ACL-RSI Score was 89.2 ± 18.3. There were 23 patients who considered themselves athletes prior to surgery, 8 patients identifying as recreational athletes competing in town or school leagues and 15 patients identifying as competitive athletes participating on youth travel or club leagues. All patients reported the ability to return to their primary sport following ACLR, with 74% returning to the same or higher level of competition, of which 6 were recreational athletes and 11 were competitive athletes. In addition, 6 patients did not complete outcomes data, but had suffered tear of their ipsilateral (3) or contralateral (3) side and were treated at the same facility. These patients were included in calculation of overall re-tear rate of 12.5% (5 patients) and contralateral tear of 25% (8 patients). Conclusion: Mid-term results of patients treated with a hybrid physeal-sparing or all-epiphyseal ACLR were favorable, with adolescents reporting a high level of functional ability and strong psychological readiness to engage in athletic activities. Re-tear and contralateral tear rates were equivalent to other reported studies. These physeal-sparing techniques demonstrate the ability for young athletes to successfully remain physically active and involved in their sports several years following surgery.

Background: The Anterior Cruciate Ligament–Specialized Post-Operative Return to Sports (ACL-SPORTS) randomized controlled trial was designed to address deficits in functional and patient-reported outcomes. The trial examined the effects of a secondary ACL prevention program that included progressive strengthening, agility training, plyometrics (SAP), and other components of current primary prevention protocols, with perturbation training (SAP + PERT group) and without PERT (SAP group). A secondary purpose of this study was to examine whether study outcomes differed between men and women. Hypotheses: (1) Athletes in both the SAP and SAP + PERT groups will have improved knee function and patient-reported outcome measures from pre- to posttraining, (2) the SAP + PERT group would have higher outcome scores than the SAP group, and (3) outcomes will differ by sex. Study Design: Randomized controlled trial (NCT01773317). Level of Evidence: Level 2. Methods: A total of 79 athletes (39 women) were randomized into the SAP and SAP + PERT groups. All athletes had undergone primary ACL reconstruction and achieved 80% quadriceps strength limb symmetry (QI), full range of motion, had minimal effusion, and had no pain. Additionally, all had begun running again. Prior to and after the training program, athletes’ QI, hopping, and patient-reported outcomes were assessed. Repeated-measures analyses of variance were used to determine whether there were differences between groups. Subsequently, the SAP and SAP + PERT groups were collapsed to analyze differences between sexes. Results: There were significant increases for all variables, with the exception of QI. There were no differences between the SAP and SAP + PERT groups. Both men and women made significant improvements in all knee function and patient-reported outcome measures except QI. Men made significant improvements in QI, whereas women did not. Conclusion: The common elements of the training program that all athletes received (10 sessions of progressive strengthening, agility training, plyometrics, and secondary prevention) may be a beneficial addition to the return-to-sport phase of ACL reconstruction rehabilitation. The results suggest that women may require further quadriceps strengthening to maintain and improve QI, an important focus given the relationship between QI and risk for reinjury. Clinical Relevance: During the return-to-sport phase of ACL reconstruction rehabilitation, clinicians tend to shift their focus away from strengthening toward more advanced sports-related tasks. These results indicate that women in particular need continued focus on quadriceps strengthening.
