Outcomes following medial patellofemoral ligament reconstruction with allograft [Meeting Abstract]
Objectives: Medial patellofemoral ligament reconstruction (MPFLR) using allograft tissue has several potential benefits including the absence of donor site morbidity, ability to predict graft parameters, and decreased operative time. The purpose of this study was to evaluate the outcomes of patients following MPFLR with allograft. Our hypothesis was that there would be a low rate of recurrent instability, and excellent clinical outcomes reported.
Method(s): A retrospective review of athletes who underwent MPFL Reconstruction, with a minimum of 12-month follow-up was performed. Recurrent instability (including re-dislocation and subluxation), Visual Analogue Scale (VAS) score, Kujala score, satisfaction, and whether they would undergo the same surgery again, were evaluated.
Result(s): Overall, follow up was attained for 131 patients with 141 knees (73.4%). The mean patient age of 25.0 years, 67.4% females, and mean time to follow-up was 46.8 months (12-111). At final follow up, the mean VAS score was 1.4 +/- 2.0, the mean Kujala score was 84.8 +/- 15.6, the mean satisfaction score was 84% +/- 26.0, and 117 (83.0%) would undergo the same procedure again if required. There was 17 (12.0%) patients that had recurrent instability, with 2 being re-dislocations (1.4%). A further procedure was performed in 14 patients (9.9%). There were no intra-operative complications in our series.
Conclusion(s): There was a low rate of recurrent instability following MPFLR with allograft, with excellent patient reported outcomes, and a low complication rate

The efficacy of intra-articular injections in the treatment of knee osteoarthritis: A network meta-analysis of randomized controlled trials
PURPOSE/OBJECTIVE:Osteoarthritis (OA) is a debilitating joint disease characterized by progressive loss of articular cartilage. Intra-articular injections are a mainstay of nonoperative treatment, however, there is controversy as to the optimal injectable for these patients. The purpose of the current study is to perform a network meta-analysis of the randomized control trials in the literature to ascertain whether there is a superior injectable nonoperative treatment for knee OA. METHODS:The literature search was conducted based on the PRISMA guidelines. Randomized control trials (RCTs) evaluating intra-articular injectables in osteoarthritic knees were included. Data was extracted and Visual Analogue Scale (VAS) scores and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, where available were analyzed at 1, 3, 6 and 12 months. Clinical outcomes were compared using a frequentist approach to network meta-analysis, with statistical analysis performed using R. The treatment options were ranked using the P-Score. RESULTS:Seventy-nine RCTs with 8761 patients were included in this review. Intra-articular injectables evaluated included autologous conditioned serum (ACS), bone marrow aspirate concentrate (BMAC), botulinum toxin, corticosteroids (CS), hyaluronic acid (HA), mesenchymal stem cells (MSC), ozone, saline placebo, platelet-rich plasma (PRP), plasma rich in growth factor (PRGF), and stromal vascular fraction (SVF). At 4-6 weeks and 3 months of follow-up, the treatment with the highest P-Score for WOMAC score was high molecular weight (HMW) HA + CS [P-Score = 0.9500 and 8503, respectively]. At 6-months follow-up, the treatment with the highest P-Score for WOMAC score was PRP [P-Score = 0.7676]. At all post-injection time points, the treatment with the highest P-Score for VAS score [P-Score Range = 0.8631-9927] and Womac score at 12 Months [P-Score = 0.9044] was SVF. CONCLUSIONS:The current evidence shows that SVF injections result in the greatest improvement in pain and functional outcomes in patients with knee OA at up to 1 year of follow-up.

Short-term complications of the Latarjet procedure: a systematic review
PURPOSE/OBJECTIVE:The purpose of this study is to evaluate the short-term complication rate following the open and arthroscopic Latarjet procedures and to meta-analyze the studies comparing the 2 approaches. METHODS:PubMed was searched according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines to find clinical and biomechanical studies comparing complication rates in open and arthroscopic Latarjet procedures. A literature search of MEDLINE, Embase, and the Cochrane Library was performed based on the PRISMA guidelines. Clinical studies reporting on the complications following the open or arthroscopic Latarjet were included. Meta-analysis was performed for comparative studies using Review Manager, version 5.3. A P value of <.05 was considered statistically significant. RESULTS:Overall, 89 studies (Level of Evidence [LOE] I: 2, LOE II: 2, LOE III: 24, LOE IV: 61) met inclusion criteria, with 7175 shoulders. Following the open Latarjet procedure, the overall complication rate was 6.1%, with a 1.9% occurrence of graft-related complications, 1.1% hardware, 1.1% wound, 0.9% nerve, and 1.2% other complications. Following the arthroscopic Latarjet procedure, the overall complication rate was 6.8%, with a 3.2% occurrence of graft-related complications, 1.9% hardware, 0.5% wound, 0.7% nerve, and 0.5% other complications. Complications were reported in 7 studies comparing 379 patients treated with the open Latarjet and 531 treated with the arthroscopic Latarjet, with no statistically significant difference between the two (P = .81). CONCLUSION/CONCLUSIONS:Our study established that the overall complication rate following the Latarjet procedure was 6%-7%, with the most common complication being graft-related. Furthermore, based on the current evidence, there is no significant difference in the complication rate between the open and arthroscopic Latarjet procedures.

No difference in 90-day complication rate following open versus arthroscopic Latarjet procedure
The purpose of this study was to compare the 90-day complication rate between the open and arthroscopic Latarjet procedure. A retrospective review of patients who underwent an open or arthroscopic Latarjet procedure at NYU Langone Health between 2012 and 2019 was performed. The complications, readmissions, and reoperations within 90 days were assessed. Outcomes were compared between the two approaches, and a p value of < 0.05 was considered to be statistically significant. The study included 150 patients (open: 110; arthroscopic: 40), with no patients lost to follow-up within the first 90 days. Both cohorts were similar in terms of patient demographics. No intra-operative complications were observed in either group. Overall, there were 4 post-operative complications with the open approach and 2 with the arthroscopic approach (3.6% and 5.0%, respectively; n.s.) during the study period. Three patients required a readmission within the 90-day period; one patient in both groups required a revision Latarjet for graft fracture, and one patient in the open Latarjet required irrigation and debridement for deep infection (n.s.). With the open approach, there were 2 (2.3%) wound complications, 1 graft complication, and 1 (1.1%) nerve injury. With the arthroscopic approach, there was 1 (2.8%) wound complication and 1 (2.8%) hardware complication. The safety, and 90-day complication and readmission profile of arthroscopic Latarjet is similar to open Latarjet procedure. LEVEL OF EVIDENCE: Level III.

Multifocal Disruption of the Extensor Mechanism of the Knee: A Case Report
CASE:A 41-year-old man presented with a transverse patella fracture and proximal patellar tendon avulsion after a fall from standing. Disruption of the extensor mechanism of the knee at multiple points is rare. He was treated operatively for his patella fracture and patellar tendon avulsion but experienced early failure of the patellar tendon fixation requiring reoperation. Both components of injury ultimately healed, and he returned to function. CONCLUSION:This case describes a rare presentation of an uncommon injury pattern affecting the extensor mechanism. This is the first report to describe multifocal failure of the extensor chain from a low-energy mechanism.

No Difference in Outcomes Following Osteochondral Allograft with Fresh Precut Cores Compared to Hemi-Condylar Allografts
OBJECTIVE:The purpose of the current study is to evaluate the clinical and radiographic outcomes at early to midterm follow-up between fresh precut cores versus hemi-condylar osteochondral allograft (OCAs) in the treatment of symptomatic osteochondral lesions. DESIGN/METHODS:A retrospective review of patients who underwent an OCA was performed. Patient matching between those with OCA harvested from an allograft condyle/patella or a fresh precut allograft core was performed to generate 2 comparable groups. The cartilage at the graft site was assessed with use of a modified Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) scoring system and patient-reported outcomes were collected. RESULTS:= 0.93). CONCLUSIONS:This study found that there was no difference in patient-reported clinical outcomes or MOCART scores following OCA implantation using fresh precut OCA cores or size matched condylar grafts at early to midterm follow-up.

Return to Play Criteria Among Shoulder Surgeons Following Shoulder Stabilization
PURPOSE/OBJECTIVE:The purpose of this study is to survey the members of North American and European shoulder surgery & sports medicine societies to evaluate their criteria for deciding when an athlete can safely return to play (RTP) following shoulder stabilization surgery. METHODS:A survey was sent to the members of the American Shoulder and Elbow Surgeons (ASES), American Orthopaedic Society for Sports Medicine (AOSSM), European Society for Sports & Knee Arthroscopy (ESSKA), and European Society for Surgery of the Shoulder and the Elbow (SECEC). Surgeons were asked which criteria they used to determine when an athlete can RTP following the arthroscopic Bankart repair and Latarjet procedures, with additional questions on how time from surgery and participation in collision sports affect return. RESULTS:Overall, 317 surgeons responded to the survey. Following arthroscopic Bankart repair, the most common criteria used were time (98.7%), strength (74.8%), and range of motion (70%). The most commonly-reported time point was 4 months (43.8%), and the majority used an additional time period, most commonly 2 months (38.2%), before allowing a collision athlete to RTP (75.4%). Interestingly, the addition of a Remplissage procedure did not affect decision-making regarding RTP in most cases (92.1%). Following the Latarjet procedure, the most common criteria used were time (98.4%), strength (67.5%), and range of motion (65.9%). Less than half reported using imaging to assess for radiographic union before allowing patients to RTP (47%), and the most common modality was plain radiography (80%). The most common time point was 4 months (33.1%), and the majority reported waiting an additional period of time, most commonly by 2 months (25.9%), before allowing a collision athlete to RTP (59.6%). CONCLUSION/CONCLUSIONS:Despite the absence of evidence-based guidelines on when athletes can safely return to play following shoulder stabilization surgery, there exists minimal variability in recommendations between North American and European shoulder surgeons. Further research is required to better define criteria for return to play after the arthroscopic Bankart repair and Latarjet procedures.

Tranexamic Acid Has No Effect on Post-operative Hemarthrosis or Pain Control Following ACL Reconstruction Using Bone Patella Tendon Bone Autograft: A Double-Blinded Randomized Control Trial
PURPOSE/OBJECTIVE:The purpose of this double-blinded randomized controlled trial was to evaluate the use of intravenous (IV) tranexamic acid (TXA) in patients undergoing primary bone-patella tendon-bone (BTB) ACLR with regard to post-operative hemarthrosis, pain, opioid consumption, quadriceps atrophy and activation. METHODS:A controlled, randomized, double-blinded trial was conducted in 110 patients who underwent ACLR with BTB autograft. Patients were equally randomized to the control and experimental groups. The experimental group received two 1-gram boluses of IV TXA, one prior to tourniquet inflation and one prior to wound closure; the control group did not receive TXA. If a clinically significant hemarthrosis was evident, the knee was aspirated, and the volume of blood (ml) was recorded. Additionally, perioperative blood loss (ml); Visual Analog Scale (VAS) on postoperative days (POD) 1-7 and post-operative weeks (POW) 1, 6 and 12; postoperative opioid consumption POD 1-7; range of motion (ROM) and ability to straight leg raise (SLR) at POW 1, 6, 12; and pre and postoperative thigh circumference ratio (TCR). RESULTS:There was no significant difference in perioperative blood loss between the TXA and control groups (32.5ml v. 35.6ml, p=0.47). The TXA group had 23 knees aspirated; control group had 26 knees aspirated (p=0.56). No significant difference seen in postoperative hemarthrosis volume with IV TXA compared to those without (26.7ml v. 37.3ml, p=0.12). There was no significant difference in VAS score between the two groups (p=0.15), additionally, there was no difference in postoperative opioid consumption (p=0.33). There was no significant difference in ROM or ability to SLR, or post-operative TCR (p > 0.05 for all). CONCLUSION/CONCLUSIONS:IV TXA in patients who undergo ACLR with BTB autograft does not significantly impact perioperative blood loss, postoperative hemarthrosis, or postoperative pain levels. Additionally, no significant differences were seen in early post-operative recovery regarding ROM or quadriceps reactivation.
