The Expanding Use of Knee Osteotomies in the Treatment of Malalignment and Joint Preservation
Lott, Ariana; Strauss, Eric J; Jazrawi, Laith M; Alaia, Michael J
This review highlights the expanding use of knee-based osteotomies in the treatment of knee joint malalignment and joint preservation. Planning and outcomes of traditional high tibial osteotomies and distal femoral osteotomies are discussed in addition to some of the challenges encountered with these procedures. Lastly, the role of patient-specific instrumentation and three-dimensional guided templating in performing osteotomies is discussed with respect to procedures that involve biplanar corrections and those performed in combination with other joint preservation procedures.

Current and Emerging Techniques in Articular Cartilage Repair
Ross, Keir A; Ferati, Sehar Resad; Alaia, Michael J; Kennedy, John G; Strauss, Eric J
Osteochondral lesions (OCL) of the knee are a common pathology that can be challenging to address. Due to the innate characteristics of articular cartilage, OCLs generally do not heal in adults and often progress to involve the subchondral bone, ultimately resulting in the development of osteoarthritis. The goal of articular cartilage repair is to provide a long-lasting repair that replicates the biological and mechanical properties of articular cartilage, but there is no widely adopted technique that results in true pre-injury state hyaline cartilage. Current treatment modalities have seen reasonable clinical success, but significant limitations remain. Microfracture provides short-term benefit with a fibrocartilage-based repair. While osteochondral autograft or allograft and autologous chondrocyte implantation can be effective, each have their strengths and shortcomings. Emerging concepts in cartilage repair, including scaffold engineering and one stage cell-based options, are continually advancing. These have the benefits of reduced surgical morbidity and potentially improved integration with surrounding articular cartilage but have not yet reached widespread clinical application. Tissue engineering strategies and gene therapy have the potential to advance the field, however, they remain in the early stages. The current article reviews the structure and physiology of articular cartilage, the strengths and limitations of present treatment modalities, and the newer ongoing innovations that may change the way we approach osteochondral lesions and osteoarthritis.

Perspectives and institutional policies on patient safety and image quality regarding the use of knee-spanning external fixators in MRI: A survey study of the Society of Skeletal Radiology
Marcel, Aaron J; Alaia, Erin F; Alaia, Michael J; Katz, Lee D; Medvecky, Michael J; Porrino, Jack
OBJECTIVE:Concerns regarding patient safety and image quality have made the use of knee-spanning external fixators in MRI a challenging clinical scenario. The purpose of our study was to poll practicing musculoskeletal radiologists on their personal experiences regarding the use of knee-spanning external fixators in MRI in an effort to consolidate practice trends for the radiologists' benefit. METHODS:A 27-item survey was created to address the institutional use, safety, adverse events, quality, and perspectives of the radiologist related to MRI of an externally fixated knee. The survey was distributed to 1739 members of the Society of Skeletal Radiology. RESULTS:A total of 72 members of the Society of Skeletal Radiology completed the survey. Most notably, 40 of 72 (55.56%) respondents are permitted to place a knee-spanning external fixator inside the MR bore at their institution, while19 of 72 (26.39%) respondents are not permitted to do so. Fourteen of 32 (43.75%) respondents have institutional guidelines for safely performing an MRI of an externally fixated knee. Twenty-five of 32 (78.13%) respondents are comfortable permitting an MRI of an externally fixated knee. CONCLUSION/CONCLUSIONS:We found a general lack of consensus regarding the decision to scan a patient with a knee-spanning external fixator in MRI. Many institutions lack safety guidelines, and providers rely upon a heterogeneous breadth of resources for safety information. A re-examination of the FDA device labeling nomenclature and expectations of the individual manufacturers may be needed to bridge this gap and help direct management decisions placed upon the provider.

Yendluri, Avanish; Alexanian, Ara; Chari, Rohit R; Corvi, John J; Namiri, Nikan K; Song, Junho; Alaia, Michael J; Li, Xinning; Parisien, Robert L
OBJECTIVE:Marrow stimulation is used to address knee cartilage defects. In this study, we used the fragility index (FI), reverse fragility index (rFI), and fragility quotient (FQ) to evaluate statistical fragility of outcomes reported in randomized controlled trials (RCTs) evaluating marrow stimulation. DESIGN/METHODS:PubMed, Embase, and MEDLINE were queried for recent RCTs (January 1, 2010-September 5, 2023) assessing marrow stimulation for cartilage defects of the knee. The FI and rFI were calculated as the number of outcome event reversals required to alter statistical significance for significant and nonsignificant outcomes, respectively. The FQ was determined by dividing the FI by the study sample size. RESULTS:Across 155 total outcomes from 21 RCTs, the median FI was 3 (interquartile range [IQR], 2-5), with an associated median FQ of 0.067 (IQR, 0.033-0.010). Thirty-two outcomes were statistically significant, with a median FI of 2 (IQR, 1-3.25) and FQ of 0.050 (IQR, 0.025-0.069). Ten of the 32 (31.3%) outcomes reported as statistically significant had an FI of 1. In total, 123 outcomes were nonsignificant, with a median rFI of 3 (IQR, 2-5). Studies assessing stem cell augments were the most fragile, with a median FI of 2. In 55.5% of outcomes, the number of patients lost to follow-up was greater than or equal to the FI. CONCLUSION/CONCLUSIONS:-values with FI and FQ metrics to aid in the interpretation of clinical findings in comparative trials assessing cartilage restoration.

Clinical and Functional Outcomes of Documented Knee Dislocation Versus Multiligamentous Knee Injury: A Comparison of KD3 Injuries at Mean 6.5 Years Follow-up
Hughes, Andrew J; Li, Zachary I; Garra, Sharif; Green, Joshua S; Chalem, Isabel; Triana, Jairo; Jazrawi, Laith M; Medvecky, Michael J; Alaia, Michael J
BACKGROUND/UNASSIGNED:Previous research has found that the incidence of neurovascular injury is greatest among multiligamentous knee injuries (MLKIs) with documented knee dislocation (KD). However, it is unknown whether there is a comparative difference in functional recovery based on evidence of a true dislocation. PURPOSE/UNASSIGNED:To determine whether the knee dislocation-3 (KD3) injury pattern of MLKI with documented tibiofemoral dislocation represents a more severe injury than KD3 MLKI without documented dislocation, as manifested by poorer clinical outcomes at long-term follow-up. STUDY DESIGN/UNASSIGNED:Cohort study; Level of evidence, 3. METHODS/UNASSIGNED:A multicenter retrospective cohort study was performed of patients who underwent surgical treatment for KD3 MLKI between May 2012 and February 2021. Outcomes were assessed using the International Knee Documentation Committee (IKDC) score, Lysholm score, Tegner activity scale, and visual analog scale (VAS) for pain. Documented dislocation was defined as a radiographically confirmed tibiofemoral disarticulation, the equivalent radiology report from outside transfer, or emergency department documentation of a knee reduction maneuver. Subgroup analysis was performed comparing lateral (KD3-L) versus medial (KD3-M) injuries. Multivariable linear regression was conducted to determine whether documented dislocation was predictive of outcomes. RESULTS/UNASSIGNED:= .007) scores. CONCLUSION/UNASSIGNED:Patients undergoing surgical management of KD3 injuries with true, documented KD had significantly worse clinical and functional outcomes than those with nondislocated joints at a mean 6.5-year follow-up. The current MLKI classification based solely on ligament involvement may be obscuring outcome research by not accounting for true dislocation.

Cannabidiol for Postoperative Pain Control After Arthroscopic Rotator Cuff Repair Demonstrates No Deficits in Patient-Reported Outcomes Versus Placebo: 1-Year Follow-up of a Randomized Controlled Trial
Alaia, Michael J; Li, Zachary I; Chalem, Isabel; Hurley, Eoghan T; Vasavada, Kinjal; Gonzalez-Lomas, Guillem; Rokito, Andrew S; Jazrawi, Laith M; Kaplan, Kevin
BACKGROUND/UNASSIGNED:Cannabidiol (CBD) has been shown recently to positively affect patient pain and satisfaction immediately after arthroscopic rotator cuff repair (ARCR). However, it is unclear whether the addition of CBD to a perioperative regimen could affect postoperative outcomes. PURPOSE/UNASSIGNED:To evaluate patient-reported outcomes among patients who underwent ARCR and received buccally absorbed CBD or an identical placebo for early postoperative pain management at 1-year follow-up. STUDY DESIGN/UNASSIGNED:Randomized controlled trial; Level of evidence, 2. METHODS/UNASSIGNED:test and Fisher exact test, respectively. RESULTS/UNASSIGNED: = .79). CONCLUSION/UNASSIGNED:Perioperative use of CBD for pain control among patients undergoing ARCR did not result in any significant deficits in pain, satisfaction, or patient-reported outcomes at 1-year postoperatively compared with a placebo control group. These findings suggest that CBD can be considered in a postoperative multimodal pain management regimen without detrimental effects on outcome.

Increased kinesiophobia leads to lower return to sport rate and clinical outcomes following osteochondral allograft transplantation of the knee
Triana, Jairo; DeClouette, Brittany; Montgomery, Samuel R; Avila, Amanda; Shankar, Dhruv S; Alaia, Michael J; Strauss, Eric J; Campbell, Kirk A
PURPOSE/OBJECTIVE:The purpose of this study is to describe the postoperative psychological state of patients following osteochondral allograft (OCA) transplantation in the knee and to determine whether patient-perceived kinesiophobia is associated with the rate of return to sport (RTS). METHODS:A retrospective review of the electronic medical record at a single institution was conducted for all patients that underwent OCA transplantation from January 2010 to 2020. Patient-reported outcomes including the visual analog scale (VAS), knee injury and osteoarthritis outcome score (KOOS) and the Tampa scale of kinesiophobia-11 (TSK-11) were collected. Patients were surveyed regarding their postoperative RTS status. RESULTS:A total of 38 patients (52.6% female) were included in our analysis. Overall, 24 patients (63.2%) returned to sport with 12 (50%) of these patients returning at a lower level of play. When comparing patients that return to sport to those that did not, patients that return had significantly superior KOOS pain (p = 0.019) and KOOS QOL (p = 0.011). Measures of kinesiophobia (TSK-11) were significantly higher among patients that did not return to sport (p = 0.014), while satisfaction (n.s.) and pain intensity (n.s.) were comparable between groups. Logistic regression models controlling for demographic factors, VAS pain scores and lesion size showed that for every one-point increase in TSK-11 kinesiophobia score, patients were 1.33 times more likely to return to sport at a lower level (p = 0.009). For every one-point increase in TSK-11 scores KOOS QOL decreased by 2.4 points (p < 0.001). CONCLUSION/CONCLUSIONS:Fear of reinjury decreases the likelihood that patients will return to their preoperative level of sport after OCA transplantation. Patients that do not return to sport report significantly greater fear of reinjury and inferior clinical outcomes, despite similar levels of satisfaction and pain compared to those that return. LEVEL OF EVIDENCE/METHODS:Level III.

Psychological Readiness to Return to Sport (RTS) and RTS Rates Are Similar in Patients After Either Bilateral or Unilateral Anterior Cruciate Ligament Reconstruction
Buldo-Licciardi, Michael; Rynecki, Nicole D; Rao, Naina; Eskenazi, Jordan; Montgomery, Samuel R; Li, Zachary I; Moore, Michael; Alaia, Michael J; Strauss, Eric J; Jazrawi, Laith M; Campbell, Kirk A
PURPOSE/UNASSIGNED:To compare psychological readiness to return to sport (RTS), RTS rate, level of return, and time to return between patients who underwent bilateral anterior cruciate ligament reconstruction (ACLR) and those who underwent unilateral ACLR. METHODS/UNASSIGNED:The electronic medical record at a single academic medical center was queried for patients who underwent ACLR from January 2012 to May 2020. The inclusion criteria were skeletally mature patients who underwent either single or sequential bilateral ACLR and who had undergone either the primary ACLR or second contralateral ACLR at least 2 years earlier. Bilateral ACLRs were matched 1:3 to unilateral reconstructions based on age, sex, and body mass index. Psychological readiness to RTS was assessed using the validated ACL Return to Sport After Injury (ACL-RSI) scale. This, along with time to return and level of RTS, was compared between the 2 cohorts. RESULTS/UNASSIGNED: = .31) between the 2 cohorts. CONCLUSIONS/UNASSIGNED:Compared with patients who undergo unilateral ACLR, patients who undergo bilateral ACLR are equally as psychologically ready to RTS, showing equal rates of RTS, time to return, and level of return. LEVEL OF EVIDENCE/UNASSIGNED:Level III, retrospective cohort study.

Patients who undergo tibial tubercle anteromedialization with medial patellofemoral ligament reconstruction demonstrate similar rates of return to sport compared to isolated MPFL reconstruction
Li, Zachary I; Garra, Sharif; Eskenazi, Jordan; Montgomery, Samuel R; Triana, Jairo; Hughes, Andrew J; Alaia, Michael J; Strauss, Eric J; Jazrawi, Laith M; Campbell, Kirk A
PURPOSE/OBJECTIVE:To investigate the rate of return to sports and sport psychological readiness between patients who underwent isolated MPFLR (iMPFLR) compared to a matched cohort of patients who underwent MPFLR with anteromedializing tibial tubercle osteotomy (MPFLR/TTO). METHODS:Patients who underwent primary MPFLR with or without TTO for recurrent patellar instability were retrospectively reviewed from 2012 to 2020 at a single institution. Preinjury sport and work information, Kujala, Tegner, Visual Analogue Score for pain, satisfaction and MPFL-Return to Sport after Injury (MPFL-RSI) score were collected. Two readers independently measured the tibial tuberosity-trochlear groove distance, Caton-Deschamps index and Dejour classification for trochlear dysplasia. Patients in iMPFLR and MPFLR/TTO groups were matched 1:1 on age, sex, body mass index and follow-up length. Multivariate regression analysis was performed to determine whether the MPFL-RSI was associated with a return to sport. RESULTS:This study included 74 patients at mean follow-up of 52.5 months (range: 24-117). These groups returned to sport at similar rates (iMPFLR: 67.6%, MPFLR/TTO: 73.0%, not significant [ns]), though iMPFLR patients returned more quickly (8.4 vs. 12.8 months, p = 0.019). Rates of return to preinjury sport level were also similar (45.9% vs. 40.5%, ns). Patients with Dejour B/C took more time to return to sport compared to patients with mild/no trochlear pathology (13.8 vs. 7.9 months, p = 0.003). Increasing MPFL-RSI score was significantly predictive of the overall return to sport (odds ratio [OR]: 1.08, 95% confidence interval [CI] [1.03, 1.13], p < 0.001) and return to preinjury level (OR: 1.07, 95% CI [1.04, 1.13], p < 0.001). Most patients in iMPFLR and MPFLR/TTO groups resumed work (95.7% vs. 88.5%, ns), though iMPFLR patients who returned to preinjury work levels did so more quickly (1.7 vs. 4.6 months, p = 0.005). CONCLUSION/CONCLUSIONS:Patients who underwent MPFLR with anteromedializing TTO demonstrated similar rates of return to sport and psychological readiness compared to an isolated MPFLR matched comparison group, though iMPFLRs returned more quickly. Patients with more severe trochlear pathology required more time to return to sports. LEVEL OF EVIDENCE/METHODS:Level III.
