RESUMEN
Background The use of artificial intelligence (AI) as a tool for patient care has continued to rapidly expand. The technology has proven its utility in various applications across several specialties in a variety of applications. However, its practicality in orthopedics remains widely unknown. This study seeks to determine if the open-access software Chat Generative Pre-Trained Transformer (ChatGPT) can be a reliable source of data for patients. Questions/purposes This study aims to determine: (1) Is the open-access AI software ChatGPT capable of accurately answering commonly posed patient questions? (2) Will there be a significant difference in agreement among the study experts in the answers generated by ChatGPT? Methods A standard list of questions for six different procedures across six subspecialties is posed to ChatGPT. The procedures chosen were anterior cruciate ligament (ACL) reconstruction, microdiscectomy, total hip arthroplasty (THA), rotator cuff repair, carpal tunnel release, and ankle fracture open reduction and internal fixation. The generated answers are then compared to expert opinion using a Likert scale based on the agreement of the aforementioned experts. Results On a three-point Likert scale with 1 being disagree and 3 being agree, the mean score across all subspecialties is 2.43, indicating at least partial agreement with expert opinion. There was no significant difference in the Likert scale mean across the six subspecialties surveyed (p = 0.177). Conclusions This study shows promise in using ChatGPT as an aid in answering patient questions regarding their surgical procedures. This opens doors for the use of the software by patients for understanding and increased shared decision-making with their surgeons. However, studies with larger participation groups are necessary to ensure accuracy on a larger and broader scale as well as studies involving specific application of AI within surgeon's practice.
RESUMEN
Introduction Anterior cruciate ligament (ACL) tears occur frequently in young athletes, and ligament repair and reconstruction are surgical treatments. Although there are suggested benefits for both approaches, there is a lack of direct comparisons between ACL repair and reconstruction.This study aims to compare the mid-term functional outcomes and quality of life measures between patients that have undergone ACL repair versus reconstruction. Methods A retrospective review was conducted for demographic and operative report data of patients who underwent an ACL repair or reconstruction between 2012 and 2018. Patients were contacted over the phone and underwent a Patient-Reported Outcomes Measurement Information System (PROMIS) survey evaluating pain interference, mobility, and function. Patients were excluded from the study if there was an incomplete operative note, missing contact information, or failure to answer phone calls. Results A total of 74 eligible patients were included, with n = 54 in the ACL reconstruction group (73.0%) and n = 20 in the ACL repair group (27.0%). Reconstruction patients had a PROMIS (median (IQR)) physical function score of 22.50 (16.00-59.00), as compared to repair patients' physical function score of 60.00 (21.50-60.00). There was a significant difference favoring repair (p = 0.040). In addition, ACL reconstruction patients had a significantly higher rate of additional procedures, with 63.0% of reconstruction patients receiving an additional operation as compared to 30.0% of repair patients (p = 0.017). The surgery type did not show a significant effect on physical function scores, while additional procedures remained significant in the linear regression analysis. Conclusion Although ACL repair is associated with improved physical function scores as compared to reconstruction in the univariate analysis, surgery type did not show significance when controlling for other variables. Further studies are necessary to compare patients with similar injuries to account for differences in additional procedures, but the results remain promising in assisting with patient-driven treatment decisions.
RESUMEN
BACKGROUND: Multiligament knee injury (MLKI) is a severe subclass of orthopedic injury and can result in significant functional impairment. Novel MLKI graft constructs such as suture augmentation aim to enhance graft strength and optimize knee stability. The purpose of this study was to present patient-reported outcome measurements of a cohort at a minimum follow-up of 2 years after multiligament knee reconstruction (MLKR) with suture augmentation. MATERIALS AND METHODS: A retrospective chart review was performed to identify patients who underwent MLKR with suture augmentation. Demographic and injury-specific variables were gathered preoperatively and postoperatively. Patients were contacted at a minimum of 2 years postoperatively to collect Patient-Reported Outcomes Measurement Information System, Multiligament Quality of Life, and Lysholm knee scores. RESULTS: Twenty-seven patients underwent MLKR with suture augmentation, with 15 being female (55.6%) and 12 being male (44.4%). The mean pain score was 49.93±9.96, the mean physical function score was 49.56±10.94, and the mean mobility score was 47.56±8.58. The mean physical impairment score was 33.96±23.69, the mean emotional impairment score was 36.55±26.60, the mean activity limitation score was 28.00±25.61, and the mean societal involvement score was 30.09±27.45. The mean Lysholm knee score for the cohort was 67.93±22.36. CONCLUSION: Patients who underwent MLKR with suture augmentation had satisfactory scores across all patient-reported outcome measurements. On the basis of these criteria, the average patient achieved an acceptable clinical outcome, demonstrating that MLKR with suture augmentation is a safe and efficacious surgical technique for the treatment of MLKI.

Introduction The goal of total knee arthroplasty is to replace diseased cartilage and bone with an artificial implant to improve the patient's quality of life. The knee has historically been reconstructed to the patient's mechanical axis (MA). However, kinematically aligned techniques have been increasingly used. Kinematic alignment requires less soft-tissue resection and aligns the knee with what is anatomically natural to the patient, while there is concern that kinematically aligned knees will lead to earlier failure due to potential unequal weight distribution on the implant. The purpose of this study is to compare the parallelism from the floor of the joint-line cuts using kinematic and mechanical alignment and understand if the MA is a proper estimation of the tibial-ankle axis (TA). Methods A retrospective study was conducted by recruiting all high tibial osteotomy and distal femoral osteotomy recipients operated on by two surgeons in two MedStar Health hospitals from 01/2013 to 07/2020 with full-length films in preparation for restorative procedures. Baseline osteoarthritis was graded using the Kellgren-Lawrence classification system with all patients presenting as Grade 0. The TA and the joint-line orientations of the MA and kinematic axis (KA) were measured on 66 legs. The average distance from parallelism to the ground was compared between the MA and the KA and between the MA and the TA using a paired t-test. Results KA joint-line orientation (1.705° deviation) was more parallel to the floor in the bipedal stance phase than the MA (2.316° deviation, p=0.0156). The MA (2.316° deviation) was not a proper estimation of the TA (4.278° deviation, p=0.0001). Conclusion By utilizing the KA technique, the restoration of the natural joint line, as well as a joint that is more parallel to the floor in the stance phase compared to the MA, is achieved. The parallelism to the ground of the KA during the bipedal stance phase suggests an even load distribution across the knee. In addition, due to its similarity to the KA and anatomical significance in weight-bearing distribution, further investigation into the hip-to-calcaneal axis as an approximation of the joint line is warranted.
RESUMEN
Purpose This retrospective cohort explores the efficacy of regional shoulder blocks using Exparel™ in patients undergoing total shoulder arthroplasty (TSA)/reverse total shoulder arthroplasty (RSA) to reduce total opioid prescription, refills, and length of stay in the acute care setting. Methods Patients who underwent TSA/RSA by a single surgeon in a three-year period were evaluated. Patients in the case group received liposomal bupivacaine 1.3% brachial plexus block while the control group received ropivacaine 0.5% interscalene brachial plexus block. Outcomes of the study included the number of opioids taken, opioids prescribed, and length of hospital stay. Results Thirty-six patients underwent TSA/RSA between January 2017 and March 2020. Patients who received an Exparel brachial plexus block had decreased opioid use within the first 24 hours after surgery compared to the ropivacaine group, 9.00 ± 14.10 and 26.20 ± 24.8 morphine milligram equivalent (MME), respectively (p=0.0213). Patients who received an Exparel brachial plexus block had decreased opioid prescriptions over the entire postoperative follow-up, 411.00 ± 200.74 MME in the case group and 593.07 ± 297.57 MME in the control group (p=0.0314). Lastly, patients who received an Exparel brachial plexus block had a shorter length of hospital stay, 1.28 ± 0.91 days as compared to the control group's 2.15 ± 1.49 days (p=0.0451). Conclusion This study demonstrates a significant reduction in opioid prescribing and use in patients who receive Exparel brachial plexus nerve blocks compared to non-liposomal local anesthetics, as well as a significant reduction in the length of hospital stay. The data suggest that Exparel use may decrease the risks associated with opioid use while providing adequate analgesia in patients undergoing shoulder arthroplasty.
RESUMEN
Background: Unicompartmental Knee Arthroplasties (UKAs) treat unicompartmental arthritic degeneration. Traditionally, they are placed in a mechanical alignment with bone cuts perpendicular to the leg's mechanical axis. Kinematic alignment, an alternative, considers the patient's pre-arthritic alignment. Methods: A retrospective study at Medstar Washington Hospital Center from 2015 to 2022 identified 72 UKA patients. Among them, 53 had mechanical alignments, and 20 had kinematic alignments. Using the Forgotten Joint Score (FJS) and Oxford Knee Score (OKS), Patient Reported Outcome Measures for these surgeries were recorded. Individuals were additionally analyzed post-surgically for Coronal Plane Alignment of the Knee (CPAK). Analysis was performed within the post-operative joint imaging, where mechanical medial proximal tibial angle (MPTA) and lateral distal femoral angle (LDFA) were measured. The arithmetic hip knee ankle angle (aHKA) and joint line obliquity (JLO) were calculated according to the results of MPTA-LDFA and MPTA + LDFA respectively and grouped in accordance with the CPAK classification. Results: Overall, there was a statistically significant response rate of 51% (>50%). According to the FJS, the mechanical cohort averaged a score of 39.1 (±33.8), while the kinematical cohort averaged 56.5 (±35.2). A two-sample t-test of this data demonstrated a statistically insignificant p-value of 0.1537. According to the OKS, the mechanical cohort averaged a score of 29.1 (±10) and the kinematical cohort averaged 38.4 (±8). A two-sample t-test of this data demonstrated a statistically significant p-value of <0.001. Of note, 7 patients had to undergo revisions in the mechanical alignment cohort compared to 0 in the kinematic alignment cohort due to aseptic loosening. Conclusion: This study demonstrates the potential benefit in patient outcomes for individuals who undergo a kinematic rather than mechanical alignment of their UKAs. The results of the CPAK data with the significance of LDFA are consistent with the goals of the mechanical and kinematic alignment respectively.
RESUMEN
PURPOSE: To compare the postoperative outcomes between Internal Brace (IB) and non-IB patients who underwent surgical management of multiple-ligament knee injuries (MLKI). METHODS: Patients who underwent surgical management of MLKI at two institutions between 2010 and 2020 were identified and offered participation in the study via the collection of postoperative functional outcomes for MLKI; Lysholm Knee score, Multiligament Quality of Life (ML-QOL), Patient-Reported Outcomes Measurement Information System (PROMIS) computer adaptive testing (CAT), Pain Interference (PI), Physical Function (PF), and Mobility instruments (MI). The postoperative outcomes and reoperation rates were compared between the IB group and non-IB group. RESULTS: One hundred and twenty-six patients were analyzed; 89 were included in the IB group (31.5% female; age 35.6 ± 1.4 years), and 37 were included in the non-IB group (25.7% female; age 38.8 ± 2.4 years). Mean follow-up time of the entire cohort was 37.9 ± 4.7 months [IB: 21.8 + 1.63; non-IB: 76.4 ± 6.2, p < 0.001). The IB group achieved similar PROMIS CAT [PROMIS Pain (51.8 + 1.1 vs. 52.1 + 1.6, p = 0.8736), Physical Function (46.6 + 1.2 vs. 46.4 + 1.8, p = 0.9168), Mobility (46.0 + 1.0 vs. 43.7 + 1.6, p = 0.2185)], ML-QOL [ML-QOL Physical Impairment (36.6 + 2.5 vs. 43.5 ± 4.2, p = 0.1485), Emotional Impairment (42.5 + 2.9 vs. 48.6 ± 4.6, p = 0.2695), Activity Limitation (34.5 + 2.8 vs. 36.2 ± 4.3, p = 0.7384), Societal Involvement (39.1 + 3.0 vs. 41.7 + 4.2, p = 0.6434)] and Lysholm knee score (64.9 + 2.5 vs. 60.4 + 4.0, p = 0.3397) postoperatively compared the non-IB group, but the differences were not significant. CONCLUSION: In this cohort of patients with MLKI treated with versus without IB, outcomes and reoperation rates trended toward favoring IB, but the study was not sufficiently powered to reach statistical significance. Internal bracing could be useful in the management of MLKI. In the future, matched patient cohorts with more patients are warranted to further evaluate the clinical impact of the internal brace in MLKI.

Purpose: to compare immediate post-operative pain and patient-reported outcomes (PROs) after partial meniscectomy with needle (NA) vs. standard (SA) arthroscopy technique. Methods: A retrospective review of a consecutive series of patients who underwent partial meniscectomy before and after adoption of a needle arthroscopic technique was performed. Meniscus repairs, root repairs, and those with ligamentous injuries were excluded. Total milligram morphine equivalents (MMEs) consumed, Visual analog scale (VAS) pain, and Knee Injury and Osteoarthritis Outcome Scores (KOOS) were compared pre-operatively and at 2 and 6-weeks postoperatively. Univariate analysis was used to compare results. Results: Nineteen patients were in each group (NA: 10 females, SA: 11 females). Mean ± SD age (NA 42.8 ± 8.4 vs. SA 47.6 ± 10.4 years, p = 0.13) and body mass index (NA 31.4 ± 5.6 vs. SA 35.1 ± 5.4 m/kg2, p = 0.06) were not significantly different. Seventeen (89%) patients in both groups had medial meniscus tears of the posterior horn. Preoperative Outerbridge score was significantly greater in the SA group (3.4 vs. 1.8, p = 0.002); however, preoperative VAS pain (NA 6.1 ± 1.7 vs. SA 6.1 ± 1.8, p = 0.98) and KOOS pain (NA 44 ± 17% vs. SA 37 ± 12.5%, p = 0.20) were similar. Amount of arthroscopic fluid used was significantly greater in the SA vs. NA group (1.4 ± 0.7 vs. 0.5 ± 0.3 L, p < 0.0001), but tourniquet time was equivalent (NA 20 ± 6 vs.16 ± 6 min, p = 0.11). VAS pain scores (NA 1.0 ± 1.1 vs. SA 2.6 ± 1.5, p = 0.0014), KOOS pain (NA 79 ± 15% vs. 58 ± 19%, p = 0.0006), and Quality of Life (QOL) scores (NA 70 ± 22% vs. SA 43 ± 24%, p = 0.001) were significantly better at 2-weeks post-op in the N group. By 6 weeks post-op, all PROs including VAS pain and KOOS scores were similar between groups. Conclusions: Adoption of a needle arthroscopic technique for partial meniscectomy was associated with significantly improved VAS and KOOS pain scores two-weeks post-operatively. Differences were not sustained at 6 weeks after surgery. Level of evidence: III, Retrospective Comparison Study.
RESUMEN
Purpose: The purpose of this study was to compare surgical outcomes in patients who underwent ACL reconstruction, with and without internal bracing, at 1-3, 4-7, and 8-12 months of postoperative physical therapy. Previous studies show that ACL reconstruction with internal bracing allows earlier and more aggressive rehabilitation. Therefore, it was hypothesized that patients with internal bracing would display superior surgical recovery compared to ACL reconstruction alone after adjusting for length of physical therapy.1, 2, 3. Methods: Patients who underwent ACL reconstruction and had a minimum two-year follow-up were included. Demographics including age, gender, use of internal bracing, and pre-operative level of activity were collected. Patient-reported outcomes were assessed using KOOS scores. Results: 46 patients underwent ACL reconstruction between January 2013 and December 2015. The mean age was 31.53 ± 8.37 years. Patients who received ACL reconstruction with internal bracing reported similar improvement in KOOS scores (mean = 42.82 ± 15.44; median = 46.39 [34.52-51.80]) compared to ACL reconstruction alone (mean = 38.18 ± 19.91; median = 40.17 [29.49-53.90]) (p = 0.475). Patients who received ACL reconstruction with internal bracing reported comparable improvement to ACL reconstruction alone at 0-3 months (Internal bracing: mean = 35.39 ± 15.26, median = 40.45 [26.49-47.73]; No internal bracing: mean = 42.51 ± 12.33, median = 39.32 [35.69-52.94], p = 0.4113), 4-7 months (Internal bracing: 41.96 ± 14.49, 45.55 [33.94-52.68]; No internal bracing: 30.64 ± 32.29, 41.65 [26.17-46.12], p = 0.7491) and 8+ months groups (Internal bracing: 63.36 ± 13.06, 63.36 [58.74-67.98]; No internal bracing: 47.05 ± 10.14, 47.05 [43.46-50.63]) (p = 0.6985). Conclusion: This study demonstrates no statistical difference in functional outcome scores when comparing patients with internally braced ACL reconstruction compared to standard reconstruction. Therefore, the increased structural support provided by use of internal bracing in ACL reconstruction does not afford to quicker improvement in patient-reported recovery.
RESUMEN
Introduction When performing total knee arthroplasty (TKA), surgeons may use either the mechanical alignment (MA) or the kinematic alignment (KA) to guide implant placement and joint balancing. By measuring preoperative and postoperative patellar height (PH), surgeons can predict knee stability after TKA. Improper PH is associated with knee instability which may complicate the postoperative course and lead to patient dissatisfaction or need for revision. The purpose of this study is to measure patellar height using the Insall-Salvati Index (ISI), Caton-Deschamps Index (CDI), and Blackburne-Peel Index (BPI) preoperatively and postoperatively in patients who underwent TKA with either MA or KA to assess for changes in patellar height. Methods We performed a retrospective eight-year review of 256 patients who underwent TKA with either MA or KA by a single surgeon at a single hospital site. We obtained demographic data, including gender, age, and BMI, via the electronic health record. Furthermore, we calculated the ISI, CDI, and BPI using necessary parameters from preoperative and postoperative radiographs. We used these measurements to assess any statistically significant difference in postoperative PH. Results The MA cohort consisted of 104 patients with an average age of 63 years and an average BMI of 34.1 kg/m2. The KA cohort included 152 patients with an average age of 64 years and an average BMI of 34.9 kg/m2. For the MA population, the average postoperative score with ISI was 1.10 [1.05 to 1.16] (p < 0.001), with CDI was 1.05 [0.98 to 1.11] (p < 0.001), and with BPI was was 0.94 [0.89 to 0.99] (p < 0.001). While for the KA population, the average postoperative score with ISI was 1.03 [0.99 to 1.06] (p = 0.17), with CDI was 0.87 [0.82 to 0.91] (p = 0.15), and with BPI was 0.82 [0.78 to 0.86] (p = 0.34). Conclusion TKA with a KA has a statistically significant improvement in postoperative PH and better postoperative maintenance of preoperative PH. Improved PH may lead to increased patellofemoral stability and superior postoperative outcomes in patients undergoing TKA. Future studies should focus on whether differences in preoperative and postoperative PH measurements result in changes in clinical outcomes in patients with MA versus KA TKA.
RESUMEN
PURPOSE: To evaluate the effect of suture augmentation (SA) of 7-mm and 9-mm diameter graft on load sharing, elongation, stiffness, and load to failure for all-inside anterior cruciate ligament reconstruction (ACLR) in a biomechanical Study was funded by Arthrex ID: EMEA-16020. full-construct porcine model. METHODS: Bovine tendon grafts, 7-mm and 9-mm diameter, with and without SA were tested using suspensory fixation (n = 8). The independent SA was looped over a femoral button and knotted on a tibial button. Preconditioned constructs were incrementally increased loaded (100N/1,000 cycles) from 100N to 400N for 4,000 cycles (0.75 Hz) with final pull to failure (50 mm/min). Isolated mechanical and optical measurements during construct loading of the SA allowed to quantify the load and elongation range during load sharing. Construct elongation, stiffness and ultimate strength were further assessed. RESULTS: Load sharing in 7-mm grafts started earlier (200N) with a significant greater content than 9-mm grafts (300N) to transfer 31% (125N) and 20% (80N) of the final load (400N) over the SA. Peak load sharing with SA reduced total elongation for 7-mm (1.90 ± 0.27 mm vs 4.77 ± 1.08 mm, P < .001) and 9-mm grafts (1.50 ± 0.33 mm vs 3.57 ± 0.54 mm, P < .001) and adequately increased stiffness of 7-mm (113.4 ± 9.3 N/mm vs 195.9 ± 9.8 N/mm, P < .001) to the level of augmented 9-mm grafts (208.9 ± 13.7N/mm). Augmentation of 7-mm (835 ± 92N vs 1,435 ± 228N, P < .001) and 9-mm grafts (1,044 ± 49N vs 1,806 ± 157N, P < .001) significantly increased failure loads. CONCLUSIONS: Load sharing with SA occurred earlier (200N vs 300N) in lower stiffness 7-mm grafts to carry 31% (7-mm) and 20% (9-mm) of the final load (400N). Loads until peak load sharing were transferred over the graft. Augmented constructs showed significantly lower construct elongation and increased stiffness without significance between variable grafts. Failure load of augmented grafts were significantly increased. CLINICAL RELEVANCE: Suture tape ligament augmentation may potentially protect biological grafts from excessive peak loading and elongation, thus reducing the risk of graft tears.

PURPOSE: The purpose of this study is to evaluate the reliability of magnetic resonance imaging (MRI) in predicting the location of ACL tears in preoperative planning for anterior cruciate ligament (ACL) repair. METHODS: Thirty-four patients who underwent ACL repair were retrospectively analyzed to compare intraoperative arthroscopic findings with preoperative MRIs. RESULTS: For identifying type I tears, the sensitivity of MRI was 9.0% and the accuracy of MRI was 8.8%. There was moderate interrater agreement between MRI findings for tear location and tear degree. CONCLUSION: MRI alone may not necessarily be accurate in identifying which ACL tears are amenable to repair. STUDY DESIGN: Retrospective case series; Level of Evidence: IV.
RESUMEN
The traditional approach of restoring a neutral mechanical axis to the lower extremity during total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA) has long been favored due its consistency and reproducibility. The kinematic alignment approach, which accounts for the patient's natural knee alignment and is commonly a few degrees varus to the mechanical axis, has gained popularity in recent years as a technique which reestablishes a more anatomic alignment. Linked Anatomic Kinematic Arthroplasty (LAKA), an extension of the kinematic approach that employs computer-assisted surgical (CAS) navigation, can improve the accuracy and precision of kinematic measurements in unicompartmental knee arthroplasties. This article will describe the LAKA technique in UKA and review early clinical outcomes associated with this technique.
RESUMEN
Negative pressure wound therapy (NPWT) has shown promise in reducing postoperative complications in several applications in orthopedic surgery, including trauma and arthroplasty. To the authors' knowledge, no study has evaluated its use in multiligament knee reconstruction. Multiligament knee reconstruction is often fraught with arthrofibrosis and wound-healing complications. This retrospective study assessed complications requiring reoperation in patients who underwent multiligament knee reconstruction and received either NPWT (n=14) or a dry sterile dressing (DSD) (n=44). There were significantly more reoperations in the cohort of patients who received a DSD (P=.011). Arthrofibrosis in particular showed a significantly lower rate of occurrence in the NPWT cohort compared with the DSD cohort (P=.025). There was a trend toward a lower infection rate in the NPWT cohort (P=.322). This study provides evidence that NPWT may be effective in reducing reoperation after multiligament knee reconstruction. Further investigations with prospective studies are needed to draw stronger conclusions about the benefits of NPWT. [Orthopedics. 2021;44(3):187-191.].

We present two cases of posterior cruciate ligament (PCL) repair with suture augmentation (SA) in the setting of multiligamentous knee injury (MLKI). Excellent clinical outcomes were obtained at two-year follow-up with both patients returning to sport following injury. Both patients demonstrated improvements in Knee Injury and Osteoarthritis Outcome Score (KOOS) that exceeded the minimal clinically important difference (MCID) as reported in the literature for ligamentous knee injuries. One patient developed arthrofibrosis, which was successfully treated with manipulation under anesthesia and arthroscopic lysis of adhesions two months postoperatively. Both patients had full knee range of motion (ROM) by a one-year follow-up. One patient returned to full preinjury level of sport at six months postoperatively while the other patient returned to 50% of preinjury intensity at two-year follow-up. This series of two cases of PCL repair with SA in MLKIs demonstrates that PCL repair with SA is a viable procedure that can result in excellent short-term outcomes and restore knee stability.
RESUMEN
PURPOSE: To determine if patients who underwent ACL repair experienced less short-term postoperative pain versus patients who underwent ACL reconstruction. METHODS: Electronic charts were retrospectively reviewed of patients who underwent ACL surgery from November 2014 through April 2019 by a single surgeon. Patients were divided into two groups based on whether they underwent ACL repair or ACL reconstruction. A two-tailed equal variance t-test was used to evaluate visual analog scale (VAS) pain scores at the first postoperative visit. A chi-squared test of independence was used to evaluate narcotic prescription refills at the first postoperative visit. RESULTS: 36 ACL repair patients and 71 ACL reconstruction patients were included. The mean visual analog scale (VAS) pain score at the first postoperative visit (12.9 ± 3.7 days post-op) for ACL repair patients (2.81 ± 1.79) was significantly lower (p = .004) compared to ACL reconstruction patients (4.07 ± 2.26). The number of narcotic prescription refills at the first postoperative visit was significantly lower (p = .027, ARR = 21.4%, NNT = 4.67) in the ACL repair group (7 of 36, 19.4%) compared to the ACL reconstruction group (29 of 71, 40.8%). CONCLUSION: Patients who underwent ACL repair experienced less short-term postoperative pain and were prescribed fewer narcotics compared to patients who underwent ACL reconstruction.

PURPOSE: To evaluate clinical outcomes and patient-reported outcomes of patients who underwent primary anterior cruciate ligament (ACL) repair using suture tape augmentation. METHODS: Patients with a proximal tear of the ACL who underwent primary ACL repair with a minimum 2-year follow-up were included. The exclusion criteria included multiligamentous knee injuries, midsubstance tears, tibial avulsion fractures, and distal tears. Demographic characteristics, injury pattern, concomitant injury pattern, and patient-reported outcome measures were recorded. Patients were evaluated at a minimum 2-year follow-up for clinical success, defined as stability not requiring revision ACL reconstruction, and for patient-reported outcome measurements. Failure was defined as the need for revision surgery. RESULTS: The mean follow-up period was 2.8 ± 0.9 years. Thirty-five patients met the inclusion criteria, with an average age of 32.2 ± 7.2 years, and 2-year follow-up was obtained for 29 of these patients. Revision surgery was required in 2 of the 29 patients (6.9%); successful treatment was achieved in the remaining 93.1%. The Single Assessment Numeric Evaluation score and Knee Injury and Osteoarthritis Outcome Score for the 27 successfully treated patients were recorded, with 70.4% having Single Assessment Numeric Evaluation scores of 80 or greater. CONCLUSIONS: This case series shows that primary surgical repair of proximal ACL tears using suture tape augmentation results in a low rate of revision surgery.

Standard multimodal pain management for anterior cruciate ligament reconstruction typically includes a combination of local anesthetics, nonsteroidal anti-inflammatory drugs, and opioids. Opioids present a substantial risk, and there is a rising number of prescription opioid-related overdoses in the United States. The goal of this study was to evaluate the quantity of opioids prescribed to patients who received liposomal bupivacaine as a component of their multi-modal pain regimen. The electronic medical records of patients who underwent anterior cruciate ligament reconstruction by a single surgeon at an urban hospital during a 2-year period were evaluated. Patients in the case group received liposomal bupivacaine and those in the control group did not. Statistical analysis of the number of pills prescribed and numeric pain rating scale scores was performed with a 2-tailed unequal variance t test. Statistical analysis of opioid prescription refills was performed with a chi-square test. A total of 67 patients were included. The mean number of 5-mg oxycodone tablets prescribed to the case group (9.29±10.29 tablets) was significantly lower (P<.01) compared with the number prescribed to the control group (66.26±37.13 tablets). Patients in the case group also were less likely to require an opioid prescription refill at the first follow-up appointment (P<.01; absolute risk reduction, 50%; number needed to treat, 2). Mean numeric pain rating scale score at 2 weeks was 2.8±2.1 in the case group and 3.8±2.4 in the control group (P=.09). Patients who received liposomal bupivacaine as part of multimodal pain management had significantly fewer opioid prescriptions. Despite the reduction in opioids prescribed, patients in the case group only showed a trend toward a reduction in pain at 2-week follow-up. [Orthopedics. 2021;44(2):e229-e235.].

Arthrofibrosis is a condition that can cause excessive scar tissue formation, leading to painful restriction of joint motion. Following total knee arthroplasty (TKA), significant arthrofibrosis can result in permanent deficits in range of motion (ROM) if not treated. Although arthroscopic lysis of adhesions (ALOA) reliably improves post-TKA ROM if performed in a timely fashion, it exposes patients to additional anesthesia, heightens the risk of infection, and increases overall medical expenses. Kinematically aligned TKA has emerged as an alternative method to mechanically aligned, basing bony cuts off of the patient's pre-arthritic anatomy while limiting need for soft tissue and ligamentous releases. This study aimed to determine whether there is a difference in the frequency of post-TKA arthrofibrosis requiring ALOA between kinematic and mechanically aligned TKA. Between 2012 and 2019, a retrospective analysis was conducted based on a single surgeon's experience. Two cohorts were made based on alignment technique. Postoperatively, patients were diagnosed with arthrofibrosis and indicated for ALOA if they had functional pain with < 90 degrees of terminal flexion at 6 weeks postoperatively despite aggressive physical therapy. Frequency of ALOA was recorded for each cohort and was regressed using independent samples t-test. The results showed no significant difference between the mechanical and kinematic cohorts for frequency of ALOA following TKA (13.2% vs. 7.3%; p = 0.2659). However, the kinematic cohort demonstrated significantly greater post-ALOA ROM compared to the mechanical group (129° vs. 113°; p = 0.0097). Future higher-powered, prospective studies are needed to clarify whether a significant difference in rates of MUA/ALOA exists between the two alignment techniques.

CASE: We report the case of a 44-year-old woman with previous anterior cruciate ligament (ACL) reconstruction 25 years ago in the right knee, who sustained a bucket-handle medial meniscus tear after pain and instability while pivoting during tennis. Magnetic resonance imaging demonstrated an intact but vertical and anterior ACL graft. A novel ACL retensioning procedure with suture augmentation (SA) was performed as the revision procedure. Excellent clinical outcomes and knee stability were obtained at both 17 and 36 months postoperatively. CONCLUSIONS: In certain cases, ACL retensioning with SA may be performed as the revision procedure for unsuccessful primary ACL reconstruction.
