Abstract
BACKGROUND Cartilage transplantation is commonly used to treat large (>4 cm2) articular cartilage defects of the knee. The 2 most common transplants are osteochondral allograft transplantation and autologous chondrocyte implantation. Several patient-reported outcome measures (PROMs) have been used to determine the efficacy of treatment, but it is unknown which measures are the most effective. PURPOSE To report the multiple PROMs used after large knee articular cartilage transplantation surgery and to compare the responsiveness between them. STUDY DESIGN Meta-analysis; Level of evidence, 4. METHODS Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic search of the PubMed/MEDLINE and Web of Science databases was performed. A total of 181 articles met inclusion criteria. Patient and study characteristics were extracted, including pre- and postoperative means for PROMs. From the articles that met inclusion criteria for responsiveness analysis (2+ PROMs reported, 1-year minimum follow-up, reported pre- and postoperative means and standard deviations; n = 131), the authors compared the responsiveness between PROM instruments using effect size and relative efficiency (RE) if a PROM could be compared with another in ≥10 articles. RESULTS A total of 10,015 patients (10,093 knees; mean age, 34.8 years; mean body mass index, 26.1) were included in this study. The mean follow-up time was 58.3 months (range, 1.5-247.2 months), imaging findings were reported in 80 articles (44.2%), patient satisfaction was reported in 39 articles (21.5%), and range of motion was reported in 10 articles (5.5%). There were 58 unique PROM instruments identified, with the most used being the International Knee Documentation Committee (IKDC) score (n = 118; 65.2%), followed by Knee injury and Osteoarthritis Outcome Score (KOOS) Pain (n = 58; 32.0%), KOOS Sport and Recreation (n = 58; 32.0%), KOOS Quality of Life (n = 57; 31.5%), KOOS Activities of Daily Living (n = 57; 31.5%), and KOOS Symptoms (n = 57; 31.5%). Overall, IKDC was found to have the greatest effect size (1.68) and the best responsiveness of the other PROMs, which include KOOS Pain (RE, 1.38), KOOS Symptoms (RE, 3.06), KOOS Activities of Daily Living (RE, 1.65), KOOS Sport and Recreation (RE, 1.44), Lysholm (RE, 1.76), and Tegner (RE, 1.56). CONCLUSION The IKDC is the most responsive PROM after large knee articular cartilage transplantation surgery. The IKDC score is recommended for assessing outcomes after cartilage transplantation surgery.

Abstract
Background Successful return to sport after anterior cruciate ligament (ACL) reconstruction (ACLR) can be affected by a patient's physical and psychological state throughout the rehabilitation process. Purpose To prospectively compare differences in patients at 6 months after primary ACLR with the ACL-Return to Sport after Injury (ACL-RSI), International Knee Documentation Committee (IKDC) or pediatric (Pedi)-IKDC, Hospital for Special Surgery Pediatric Functional Activity Brief Scale (Pedi-FABS), and Patient-Reported Outcomes Measurement Information System-Psychological Stress Experiences (PROMIS-PSE) scores. Study Design Prospective cohort study; Level of evidence, 2. Methods Patients enrolled were 8 to 35 years old who underwent primary ACLR and had their 6-month follow-up appointments between December 2018 and March 2020. Patients were divided into 3 age groups as follows: (1) preadolescents (10-14 years); (2) adolescents (15-18 years); and (3) adults (>18 years). Outcomes on the ACL-RSI, IKDC/Pedi-IKDC, Pedi-FABS, and PROMIS-PSE were compared according to age group, graft type (hamstring, patellar tendon, quadriceps, or iliotibial band autograft), and sex. Results A total of 176 patients (69 male, 107 female), with a mean age of 17.1 ± 3.1 years were included in the study. The mean ACL-RSI scores were significantly different among age groups (preadolescents, 75 ± 18.9; adolescents, 61.5 ± 20.4; and adults, 52.5 ± 19.8 [P < .001]) and graft types (P = .024). The IKDC and PROMIS-PSE scores were also significantly different among age groups (P < .001 and P = .044, respectively) and graft types (P = .034 and P < .001, respectively), with the iliotibial graft and the younger age group performing the best. There was no significant difference in the Pedi-FABS either by age group (P = .127) or graft type (P = .198). Female patients had lower ACL-RSI scores and higher (worse) scores on PROMIS-PSE than their male counterparts (P = .019 and P < .001, respectively), with no sex-based differences on IKDC or Pedi-FABS scores. The ACL-RSI and IKDC were positively correlated (Spearman r = 0.57; P < .001), while the ACL-RSI and PROMIS-PSE were negatively correlated (Pearson r = -0.34; P < .001). Conclusion This study suggests that psychological profiles and subjective perceptions of knee function 6 months after ACLR may vary in patients of different ages and between the sexes. Preadolescent patients had better scores on a majority of patient-reported outcomes compared with adolescent and adult patients.

Arthroscopy 2021; 37:1588-1596. [PMID: 33359816 DOI: 10.1016/j.arthro.2020.12.204] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Revised: 09/22/2020] [Accepted: 12/16/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE The primary aim was to compare osteochondral allograft (OCA) transplantation outcomes between adolescent patients aged 16 years or younger and those older than 16 years. A secondary aim was to analyze the association between physeal closure status and outcomes. METHODS Consecutive patients aged 18 years or younger who underwent OCA transplantation with a minimum 2-year follow-up were identified from a prospectively collected database. Patients were divided into 2 groups: those aged 16 years or younger (group 1) and those aged 17 to 18 years (group 2). Outcomes included patient-reported outcomes (PROs), complications, reoperations, and cartilage revision surgery. Outcomes were compared between groups, and physeal status was analyzed as a prognostic indicator. RESULTS A total of 36 patients met the inclusion criteria: 18 in group 1 and 18 in group 2. There were no significant differences between the groups in terms of demographic characteristics, prior surgical procedures, and surgical details, including concomitant procedures. The mean overall follow-up period was 4.6 ± 2.5 years (range, 2-10.3 years), with no significant difference between the groups (P = .21). There were 10 reoperations (28.8%), 4 in group 1 and 6 in group 2 (P = .47). The overall time to reoperation was 2.8 years and did not significantly differ between groups (P = .75). The failure rate was 5.6%, with 1 patient in each group undergoing either graft debridement or revision OCA transplantation. All PROs were significantly improved postoperatively (P < .05), except for the Western Ontario and McMaster Universities Arthritis Index stiffness score (P = .28) and the Short Form 12 mental score (P = .19). There were no significant between-group differences in terms of PROs. Patients with closed physes had a significantly greater increase in most PROs compared with patients with open physes (P < .05). CONCLUSIONS OCA transplantation in adolescents results in significant PRO score improvement and a low failure rate, albeit reoperations are not uncommon. Patients with closed physes show greater PRO score improvement than those with open physes. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Performance of PROMIS Physical Function, Pain Interference, and Depression Computer Adaptive Tests Instruments in Patients Undergoing Meniscal Surgery. Arthrosc Sports Med Rehabil 2020; 2:e451-e459. [PMID: 33134980 PMCID: PMC7588601 DOI: 10.1016/j.asmr.2020.04.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2019] [Accepted: 04/23/2020] [Indexed: 12/27/2022] Open
Abstract
Purpose To compare the performance of the Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF), pain interference (PIF), and depression computer adaptive tests (CAT) relative to legacy instruments in patients undergoing meniscal surgery. Methods Patients scheduled to undergo meniscal surgery completed legacy knee function PROMs (International Knee Documentation Committee [IKDC], Knee Injury and Osteoarthritis Outcome Score [KOOS] subscores), Marx Activity Rating Scale (MARS), Veterans-Rand 12 (VR12), Short Form 12 (SF12), and the Brief Resilience Scale (BRS) alongside PROMIS PF, PIF, and Depression preoperatively. Spearman rank correlations were calculated, and score distributions were examined for floor and ceiling effects. Results 152 patients (46.6 ± 14.9 years, 67.1% male) completed PROMs for appropriate inclusion. PROMIS PF yielded high-moderate to high correlations with the IKDC and KOOS subscales (r = 0.61 to 0.73), demonstrating similar performance to the IKDC. PROMIS PIF demonstrated moderately high-moderate to high correlations with the IKDC, KOOS subscales, VR-12 Physical Component Score (PCS), and SF12 PCS (r = 0.62 to 0.71), performing comparably to KOOS Pain (r = 0.55 to 0.92). PROMIS Depression demonstrated moderate to high-moderate correlations with the mental health legacies (r = 0.46 to 0.66). Significant ceiling effects were observed for MARS (n = 29, 18.8%), and significant floor effects were exhibited by PROMIS Depression (n = 38, 25%) and MARS (n = 27, 17.6%). Conclusion The PROMIS PF, PIF CAT, and Depression instruments exhibit comparable performance profiles relative to legacy knee PROMs. PROMIS PF and PIF demonstrated no floor and ceiling effects, whereas PROMIS Depression exhibited a significant relative floor effect. PROMIS PF and PIF may be appropriately used to establish functional baselines preoperatively. Level of Evidence IV, diagnostic case series.

Time interval affects physical activity scores: a comparison of the Marx Activity Rating Scale and the Hospital for Special Surgery Pediatric Functional Activity Brief Scale. Knee Surg Sports Traumatol Arthrosc 2020; 28:2619-2625. [PMID: 32076731 DOI: 10.1007/s00167-020-05895-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2019] [Accepted: 01/29/2020] [Indexed: 10/25/2022]
Abstract
PURPOSE The Marx Activity Rating Scale (Marx Scale) is a commonly used activity-related patient-reported outcome which evaluates the highest activity level within the last year, whereas the Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS) assesses highest activity level within the last month. This study aims to determine whether the different timeframes used for the common items of Marx Scale and HSS Pedi-FABS affect scores, and if so, to determine whether age or injury status affect this difference. METHODS The Marx Scale and four analogous items on the HSS Pedi-FABS were administered in random order to patients being evaluated for knee injuries and in addition to healthy controls to enroll an uninjured comparison group. Responses to each question were scored from 0 to 4 for a maximum overall score of 16. Paired and independent-sample t tests were used to determine mean differences between groups. RESULTS The final cohort included 88 participants of which 47% were children (ages 10-17) and 51% had a knee injury. All participants except for healthy adults scored significantly lower on the HSS Pedi-FABS than the Marx Scale (p < 0.05). On the HSS Pedi-FABS activity scale, healthy participants scored significantly higher than injured participants (p < 0.01), but there were no significant differences based on age. Conversely, on the Marx Scale, children scored higher than adults (p ≤ 0.001), but there were no significant differences based on injury. CONCLUSION Physical activity level differs when evaluated with the Marx Scale or the analogue part of HSS Pedi-FABS with timeframe being the only difference between the two. The lower scores on the HSS Pedi-FABS are likely due to seasonal changes in activity which do not affect the Marx Scale. HSS Pedi-FABS analyzes a shorter window and it is more likely to capture changes in physical activity due to a recent injury than the Marx Scale which is better suited for assessing general physical activity level unaffected by seasonality or recent injury. Understating the differences between these physical activity scales can better guide clinicians when using them and interpreting scores. LEVEL OF EVIDENCE II.

Abstract
BACKGROUND Traumatic patellofemoral dislocation is a common injury in pediatric patients, and surgical treatment is often recommended. Increasingly, it has been recognized that clinical studies need to report age-appropriate treatment outcomes. However, the variability and appropriateness of outcomes reporting in the youth patellar instability literature are unknown. PURPOSE To analyze the patterns of outcomes reporting in studies published in high-impact orthopaedic journals after operative management of pediatric patellar instability. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS Six high-impact orthopaedic journals were searched using PubMed and EMBASE to identify studies reporting outcomes of operative management of pediatric patellar instability. Studies containing adults were excluded. Clinical and radiographic outcomes were recorded from included articles. Descriptive statistics were calculated for overall instability recurrence rates, return-to-activity rates, and changes in Kujala and Tegner scores. RESULTS Of 545 identified articles, 8 studies met the inclusion criteria. These studies encompassed 213 patients and 230 knees (mean age, 13.2 years; range, 4.5-18.3 years). Seven of 8 studies reported patients' physeal status, but only 4 studies limited their outcomes reporting to patients with open physes. Two studies reported postoperative radiographic measures, and 5 studies reported preoperative radiographic findings. Six studies reported patient-reported outcome measures (PROMs). Seven unique PROMs were reported. All but one study reported complication rates and types of complications. The mean postoperative change in Tegner scores was -0.07 (range, -0.6 to 1.0). Among studies examining medial patellofemoral ligament reconstruction with adequate data, the mean return-to-activity rate was 86% (range, 81%-92%), the instability recurrence rate was 3% ± 20%, and the mean improvement in Kujala scores postoperatively was 22.1 (range, 19.9-26). CONCLUSION There is a need for more pediatric-specific outcomes studies regarding operatively managed traumatic patellofemoral instability. Of the outcomes reported, both radiographic outcomes and PROMs should be standardized. Among radiographic outcomes, there is a need for more studies that report tibial tubercle-trochlear groove distances and use Caton-Deschamps and/or Blackburne-Peel indices to assess patellar height. Among PROMs, there is a need for studies that use PROMs validated in pediatric populations, such as the International Knee Documentation Committee Pediatric Form or the Hospital for Special Surgery Pediatric Functional Activity Brief Scale.

Abstract
BACKGROUND The International Knee Documentation Committee Subjective Knee Form (IKDC-SKF) is a validated patient-reported outcome used in clinical research. No studies exist directly comparing the standard unilateral adult version (IKDC-SKF) with the bilateral adult version (R/L IKDC-SKF). HYPOTHESES The first hypothesis is that no clinically relevant difference would be observed between standard IKDC-SKF scores and involved R/L scores. The second hypothesis is that a relevant difference would be observed between involved and uninvolved scores on the R/L IKDC-SKF. STUDY DESIGN Cohort study (Diagnosis); Level of evidence, 2. METHODS One hundred patients were enrolled via a crossover study design. Participants were split into 2 groups per simple randomization. One group completed the standard IKDC-SKF first and the R/L IKDC-SKF second. The other group completed forms in the reverse order. A 10-minute washout period was administered between questionnaires. Participants reported their preferred form in a postquestionnaire survey. A 5-point threshold for clinical relevance was set a priori, which is less than multiple published minimal detectable change and minimal clinically important difference metrics of the standard IKDC-SKF, ranging from 6.3 to 20.5. Data were analyzed with Bland-Altman plots, paired t tests, correlations, and chi-square tests. RESULTS Paired t tests between the standard IKDC-SKF and the involved R/L IKDC-SKF scores demonstrated a statistically significant mean difference of 1.4 ( P = .008; 95% CI, 0.4-2.4). However, the 95% CI falls under the clinically relevant threshold of 5. Standard and involved knee scores from the R/L IKDC-SKF were highly correlated, with a rho of 0.95. Patients consistently distinguished the injured knee from the uninjured knee across a range of scores via the R/L IKDC-SKF ( P < .001). The postquestionnaire survey showed that 55 patients preferred the R/L IKDC-SKF, 30 preferred the standard IKDC-SKF, and 15 had no preference. Post hoc analysis showed a significant preference for "R/L vs standard IKDC-SKF" ( P = .014) and "R/L IKDC-SKF vs no preference" ( P < .003). CONCLUSION No clinically relevant difference was observed between the standard IKDC-SKF and the involved knee score of the R/L IKDC-SKF. Therefore, for symptomatic unilateral knee diagnosis, either form can be used. The R/L IKDC-SKF showed a consistent and clinically relevant difference between involved and uninvolved knees. Patients in this study preferred the R/L IKDC-SKF.

Abstract
Background: Advances in anterior cruciate ligament (ACL) reconstruction procedures in pediatric and adolescent patients have resulted in an increase in recent clinical studies on this topic. However, the consistency with which outcome measures are reported in this demographic is unknown. Purpose: To document outcome reporting patterns of youth ACL reconstruction studies in high-impact journals. Study Design: Systematic review; Level of evidence, 4. Methods: All articles published in 5 high-impact orthopaedic journals from 2010 to 2016 were reviewed to identify those reporting clinical outcomes of young patients who underwent ACL reconstruction. Studies that were nonclinical, reported on patients older than 18 years, or included fewer than 10 patients were excluded. Outcome measures used in all included studies were recorded. Results: Seventeen studies encompassing 772 subjects (mean age, 14.3 years; range, 6.3-18.0 years) were analyzed. Eight studies (47%) reported on Tanner stage of subjects, while 1 study reported skeletal age. Ten studies (59%) clearly documented the presence or absence of surgical complications. Range of motion was reported in 65% of studies. Leg-length discrepancy and angular deformity were each reported in 76% of studies, with 12% quantifying results through radiographic measurements. Ligament testing was variably defined by inclusion of instrumented testing (65%), Lachman test (53%), and pivot-shift test (53%). Fourteen studies (82%) explicitly reported on the rate of ACL rerupture, while 71% reported on the rate of revision surgery. Rate of return to preinjury activity was reported in 8 studies (47%), of which 2 defined criteria for return to sport and 3 defined the level of competitive sport. Patient-reported outcome measures (PROMs) were used variably. For the 3 most commonly reported PROMs (Lysholm, International Knee Documentation Committee, and Tegner), 24% of studies reported all 3 PROMs, 35% of studies reported 2 PROMs, and 6% of studies reported 1 PROM in isolation. A pediatric-specific PROM was reported in 1 of the 17 studies. Conclusion: Studies on pediatric ACL reconstruction published in high-impact journals unreliably defined subjects’ skeletal maturity, inconsistently reported on objective outcome measures, and used disparate adult-validated PROMs to assess subjective outcomes. These findings highlight the need for standardized, pediatric-specific outcome measures to be applied in future studies evaluating ACL reconstruction in children and adolescents.
