Abstract
BACKGROUND Although preservation of meniscal tissue is paramount, there are occasions when repair of a torn meniscus is not possible. The surgical option may be a partial meniscectomy, the objective being to alleviate the patient's symptoms with resection of only that portion of the meniscus that is no longer functioning but is the cause of symptoms. Previous studies have questioned the need to perform such surgery and have recommended nonoperative treatment instead. Our goal was to compare the outcome of partial meniscectomy with that of physiotherapy alone for irreparable meniscal tears. HYPOTHESIS Clinical outcome following arthroscopic partial meniscectomy may differ from that following physiotherapy alone, for patients with symptomatic irreparable meniscal tears. STUDY DESIGN Nonrandomized prospective cohort study. LEVEL OF EVIDENCE Level 2. METHODS Patients satisfying the inclusion criteria chose to undergo knee arthroscopy (group A) or physiotherapy (group B). The diagnosis of a meniscal tear was made on physical assessment and magnetic resonance imaging examination. The meniscal tear was preventing them from continuing with their regular weightbearing exercise. Outcomes of interest were the following patient-reported outcomes (PROs): the Knee Osteoarthritis Outcome Score (KOOS) and Tegner Activity Score (TAS), with minimal clinically important differences being 10 and 1, respectively. PROs were completed at baseline, and at 1-year and 2-year follow-up. Changes in scores within and between groups were compared using analysis of variance and Wilcoxon tests (P <0.05). A power analysis demanded 65 patients in each group to produce a power of 80% and a P value of 5%. RESULTS Of 528 patients enrolled in the study, 10 were lost to follow-up and 8 were excluded. Data were complete for 269 in group A, and 228 in Group B. Group A and B were similar in terms of age (41.1 years, SD 7.8 vs 40 years, SD 13.3), body mass index (22.5 kg/m2, SD 3.1 vs 23.1 kg/m2, SD 2.3), radiographic grade of osteoarthritis (median grade 2, range 0-3 in both groups), gender (male:female = 134:135 vs 112:116), and duration of symptoms (44.4 days, SD 5.6 vs 46.6 days, SD 8.8), with P >0.05. At both 1-year and 2-year follow-up, Group A had higher scores in the mean total KOOS (88.8, SD 8.0 vs 72.4, SD 3.8), as well as in all subscales within the KOOS, and the TAS (median 7, range 5-9 vs median 5, range 3-6), with P <0.001 for each variable. CONCLUSION Performing a knee arthroscopy with partial meniscectomy is associated with improved KOOS and TAS, relative to treatment with physiotherapy alone, at 2-year follow-up. CLINICAL RELEVANCE Physically active patients with symptomatic irreparable meniscal tears may experience a better clinical outcome following knee arthroscopy, relative to to physiotherapy alone.

Abstract
BACKGROUND An accessory extreme far anteromedial portal can improve visualisation and ease inferior leaf meniscectomy in patients with lateral meniscal anterior horn horizontal tears. However, the therapeutic outcomes of adding an accessory extreme far anteromedial portal remain unclear. This study aimed to evaluate the clinical efficacy of adding an accessory extreme far anteromedial portal for treating lateral meniscal horizontal tears involving the anterior horns. METHODS This retrospective study included 101 patients with anterior horn involvement in lateral meniscal horizontal tears who underwent arthroscopic unstable inferior leaf meniscectomy between January 2016 and December 2020. The pathologies were diagnosed using physical examinations and magnetic resonance imaging. The anterior horn involved in the lateral meniscal horizontal tears was treated using inferior leaf meniscectomy. The primary endpoints were changes in the visual analogue scale, Lysholm, International Knee Documentation Committee, and Tegner scores at the final follow-up. The secondary endpoint was meniscal cure rate at 3 months postoperatively. The preoperative and postoperative functional scores were compared. The occurrence of complications was recorded. RESULTS All patients were followed up for an average of 4.9 ± 1.2 years (range 2.3-7.5 years). After 4 months, none of the patients experienced pain, weakness, instability, or tenderness in the lateral joint line, achieving an imaging cure rate of 98%. At the final follow-up, significant postoperative improvements were observed in the average values of the visual analogue scale score (3.5 ± 0.7 vs. 0.7 ± 0.6), Lysholm score (62.7 ± 4.4 vs. 91.8 ± 3.1), International Knee Documentation Committee score (61.9 ± 3.7 vs. 91.7 ± 9.5), and Tegner score (2.0 ± 0.7 vs. 6.1 ± 0.7). Excellent Lysholm scores were obtained in 81 patients, and good outcomes were obtained in 18 patients, with an excellent-to-good rate of 98.0%. CONCLUSIONS Inferior leaf resection via the accessory far anteromedial portal is a safe treatment option for the involved anterior horn in lateral meniscal horizontal tears. This approach enhances visibility and facilitates surgical procedures, with minimal complications.

Abstract
BACKGROUND Total knee arthroplasty (TKA) is a commonly performed knee surgery and prior arthroscopic meniscectomy (AM) has been linked to an increased risk of TKA in the general population. OBJECTIVE To study the relationship between AM and TKA among injured workers whose medical care is paid for under workers' compensation (WC). METHOD A total of 17,247 lost-time claims depicting all arthroscopic knee surgical procedures performed from 2007 to 2017 were followed to the end of 2022 and analyzed. RESULTS The odds ratio of undergoing a TKA for those with a preceding AM is 2.20, controlling for age, sex, and attorney involvement. CONCLUSIONS Undergoing an AM is associated with an increased risk of TKA in WC claimants.

Abstract
The young, active patient with pain after subtotal meniscectomy represents a troubling clinical situation with limited treatment options. "Post-meniscectomy syndrome" occurs at a rate of 4-25% and is defined as the presence of knee pain and functional limitations due to increased contact stresses and overload of the articular cartilage in a knee compartment, after subtotal or total meniscectomy. Meniscal allograft transplantation (MAT) can have reasonable results for some patients, typically under the age of 50, with no degenerative change, and no, or correctable instability or malalignment. However, MAT is expensive, it is often difficult to access meniscal allograft tissue, and the procedure can be technically challenging for the surgeon. Meniscal scaffolds have been commercially available and examined in small studies in the literature and metanalyses since the early 2000s. Generally, patients have shown clinical improvement with their use, but over time, they have shown signs of radiologic failure (decrease in size of the meniscal scaffold, meniscal extrusion on MRI, or other radiographic changes.) Nonetheless, recent research shows long-term survivorship of a polyurethane scaffold in some, carefully selected patients. While not shown to be chondroprotective, this could serve as a bridge to MAT or arthroplasty.

Abstract
PURPOSE The reliable data on the incidence of hypermobile lateral meniscus (HLM) and its clinical manifestations, diagnostic methods and therapeutic approaches are limited. This systematic study aimed to review available treatment options for HLM and the outcomes of each approach. METHODS A systematic search was performed in four electronic databases (PubMed, EMBASE, Scopus, Web of Science) to identify studies in which arthroscopically confirmed cases of HLM were treated surgically or nonsurgically, and the required data comprising study characteristics, patient data, treatment approaches and outcome measures were extracted from eligible studies. RESULTS Twenty studies with a total of 212 patients (138 males and 74 females) and 219 knees were included. The most frequently reported symptoms were locking sensations, knee pain, giving way and snapping. Treatments used by the studies were: radiofrequency energy in two studies; arthroscopic partial meniscectomy in one study; open surgery in two studies; and arthroscopic meniscal repair in 17 studies. Eleven studies used an all-inside repair method and an inside-out meniscal repair was reported in eight studies. Three studies reported the usage of posterior arthroscopy for therapeutic or diagnostic approaches. Evaluation of symptom resolution was the main outcome measurement for which almost all of the studies stated relief of symptoms after intervention. CONCLUSION Despite the lack of definite consensus about the most appropriate intervention for HLM, therapeutic preference was directed towards arthroscopic all-inside and inside-out repair techniques. Although the surgeon's decision remains the key factor in choosing the most suitable treatment option for each individual, posterior arthroscopic meniscal repair may be considered as a better option for HLM treatment according to the findings of this review. LEVEL OF EVIDENCE Level IV.

Abstract
Over the last several years, there has been a shift from arthroscopic partial meniscectomy to meniscal repair, especially in the younger patient. In case of a necessary partial meniscectomy, some patients have unremittent symptoms of pain and effusion corresponding to the postmeniscectomy syndrome. In these patients without large coronal malalignment, meniscal allograft transplantation is a valuable option to restore contact pressures, promote a chondroprotective microenvironment, and potentially delay secondary surgical interventions symptoms. In the adolescent population, meniscal allograft transplantation has been shown to effectively improve patient-reported outcomes with a low conversion to arthroplasty. However, these treatments are far from ideal, and prevention is certainly better than the cure: timely diagnosis of meniscus injuries, appropriate treatment with meniscus repair rather than partial meniscectomy, even in the complex tear patterns, and consideration of corrective osteotomy for milder cases of malalignment.

Abstract
BACKGROUND Preoperative risk factors contributing to poor outcomes after arthroscopic partial meniscectomy (APM) have not yet been consolidated and codified into an index scoring system used to predict APM success. PURPOSE To create an index score using available preoperative factors to predict the likelihood of favorable postoperative outcomes after APM. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS A consecutive cohort of patients undergoing primary APM were enrolled in this study. Patients completed pre- and postoperative patient-reported outcome measure (PROM) questionnaires that included the Knee injury and Osteoarthritis Outcome Score (KOOS), visual analog scale (VAS) for pain, Veterans RAND 12-Item Health Survey (VR-12 Physical and Mental), and Marx Activity Rating Scale (MARS). Multivariable logistic regression models were performed to evaluate independent predictors of KOOS Pain, Symptoms, and Activities of Daily Living scores and achievement of the minimal clinically important difference (MCID) and substantial clinical benefit (SCB). The authors assigned points to each variable proportional to its odds ratio, rounded to the nearest integer, to generate the index score. RESULTS In total, 468 patients (mean age, 49 years [SD, 10.4 years; range, 19-81 years]) were included in this study. In the univariate analysis, shorter symptom duration, lower Kellgren-Lawrence (KL) grade, lower preoperative KOOS Pain value, and lower VR-12 Physical score were associated with a higher likelihood of clinical improvement at 1 year. In the multivariable model for clinical improvement with MCID, symptom duration (<3 months: OR, 3.00 [95% CI, 1.45-6.19]; 3-6 months: OR, 2.03 [95% CI, 1.10-3.72], compared with >6 months), KL grade (grade 0: OR, 3.54 [95% CI, 1.66-7.54]; grade 1: OR, 3.04 [95% CI, 1.48-6.26]; grade 2: OR, 2.31 [95% CI, 1.02-5.27], compared with grade 3), and preoperative KOOS Pain value (score <45: OR, 3.00 [95% CI, 1.57-5.76]; score of 45-60: OR, 2.80 [95% CI, 1.47-5.35], compared with score >60) were independent significant predictors for clinical improvement. The scoring algorithm demonstrated that a higher total score predicted a higher likelihood of achieving the MCID: 0 = 40%, 1 = 68%, 2 = 80%, 3 = 89%, and 4 = 96%. CONCLUSION Using this model, the authors developed an index score that, using preoperative factors, can help identify which patients will achieve clinical improvement after APM. Longer symptom duration and higher KL grade were associated with a decreased likelihood of clinical improvement as measured by KOOS Pain at 1 year postoperatively.

Abstract
BACKGROUND Total meniscectomy for treating massive meniscal tears may lead to joint instability, cartilage degeneration, and even progressive osteoarthritis. The meniscal substitution strategies for advancing reconstruction of the meniscus deserve further investigation. HYPOTHESIS A decellularized meniscal scaffold (DMS) modified with collagen affinity stromal cell-derived factor (C-SDF1α) may facilitate meniscal regeneration and protect cartilage from abrasion. STUDY DESIGN Controlled laboratory study. METHODS The authors first modified DMS with C-SDF1α to fabricate a new meniscal graft (DMS-CBD [collagen-binding domain]). Second, they performed in vitro studies to evaluate the release dynamics, biocompatibility, and differentiation inducibility (osteogenic, chondrogenic, and tenogenic differentiation) on human bone marrow mesenchymal stem cells. Using in vivo studies, they subjected rabbits that received medial meniscectomy to a transplantation procedure to implement their meniscal graft. At postoperative weeks 6 and 12, the meniscal regeneration outcomes and chondroprotective efficacy of the new meniscal graft were evaluated by macroscopic observation, histology, micromechanics, and immunohistochemistry tests. RESULTS In in vitro studies, the optimized DMS-CBD graft showed notable biocompatibility, releasing efficiency, and chondrogenic inducibility. In in vivo studies, the implanted DMS-CBD graft after total meniscectomy promoted the migration of cells and extracellular matrix deposition in transplantation and further facilitated meniscal regeneration and protected articular cartilage from degeneration. CONCLUSION The new meniscal graft (DMS-CBD) accelerated extracellular matrix deposition and meniscal regeneration and protected articular cartilage from degeneration. CLINICAL RELEVANCE The results demonstrate that the DMS-CBD graft can serve as a potential meniscal substitution after meniscectomy.

Abstract
OBJECTIVES To determine the changes in knee flexion moment (KFM) and knee adduction moment (KAM) during weight-bearing activities following meniscectomy. DESIGN Meta-Analysis. SETTING Laboratory. PARTICIPANTS 332 meniscectomy patients and 137 healthy controls (from 13 qualified studies) MAIN OUTCOME MEASURES: Cohen's d effect sizes (ESs) were calculated to compare KAM and KFM values of the surgical legs to the non-surgical and to healthy control legs. RESULTS When compared to healthy controls, meniscectomy patients' surgical legs demonstrated a significantly greater KAM (ES = 0.310; P = 0.002) but no significant difference in KFM (ES = -0.182; P = 0.051). When compared to the patients' non-surgical legs, however, the surgical legs showed no difference in KAM (ES = -0.024; P = 0.716) but a significantly lower KFM (ES = -0.422; P < 0.001). High heterogeneity among study ESs was observed in patients' between-limb comparison for KAM (Q-value = 20.08, P = 0.005; I2 = 65.1%) and KFM (Q-value = 43.96, P < 0.001; I2 = 79.5%). However, no significant differences in study ESs (all P > 0.102) of KFM and KAM were identified when comparing studies with various times post-surgery, weight-bearing tasks, walking speeds, or patient demographics. CONCLUSION Elevated KAM and reduced/asymmetrical KFM observed in meniscectomy patients may contribute to the increased risk of knee OA. Rehabilitation should focus on movement education to restore between-limb KFM symmetry and reduce KAM bilaterally post-meniscectomy.

Abstract
BACKGROUND The prevalence of anxiety among patients undergoing arthroscopic surgery and its association with postoperative function has been well documented; however, the level of anxiety and anxiety-related characteristics remain unclear. As such, the present study investigated the characteristics of state anxiety in patients undergoing arthroscopic meniscectomy. METHODS Data from 75 patients, who underwent arthroscopic partial meniscectomy under general anesthesia and completed an anxiety status questionnaire between April 2021 and March 2022, were retrospectively collected and reviewed. The State-Trait Anxiety Inventory (STAI)-X was used to measure state anxiety; a total score ≥ 52 was defined as clinically meaningful state anxiety. STAI score, main cause of preoperative anxiety, most anxious period, and most helpful factors for reducing perioperative anxiety were investigated. Patients were divided into 2 groups according to the main cause of preoperative anxiety; surgery or anesthesia (group I [n = 47]); and postoperative pain or rehabilitation (group II [n = 28]) Characteristics of state-anxiety between the two groups were compared using independent t-tests. RESULTS The mean STAI score of the total population was 39.1 points (range, 20-60 points). The mean STAI score was significantly higher in group I than in group II (41.9 vs. 34.4 points, respectively; P < 0.001). The proportion of patients with clinically meaningful state anxiety was significantly higher in group I than in group II (23.4% vs. 3.6%, respectively, P = 0.02). Most patients (66.0% in group I and 50.0% in group II) responded that trust in medical staff was the most helpful factor in overcoming preoperative anxiety. In group I, 63.8% reported that the surgeon's explanation was the most helpful factor in reducing postoperative anxiety, whereas in group II, 71.4% reported that the natural course after surgery was the most helpful factor. CONCLUSIONS Surgeons should be aware that anxiety related to arthroscopic meniscectomy differs according to patient characteristics, and a preoperative explanation of the postoperative process with the surgeon is important for patients who experience preoperative anxiety regarding anesthesia or the surgery itself.

Abstract
OBJECTIVES Although meniscal allograft transplantation (MAT) is a well-established procedure with satisfactory clinical results, limited in vivo kinematic information exists on the effect of medial and lateral MAT performed in the clinical setting. The purpose of the present study was to evaluate the biomechanical effect of arthroscopic isolated medial and lateral MAT with a soft-tissue fixation on pre- and post-operative knee laxity using a surgical navigation system. METHODS 18 consecutive patients undergoing MAT (8 medial, 10 lateral) were enrolled. A surgical navigation system was used to quantify the anterior-posterior displacement at 30 and 90 degrees of knee flexion (AP30 and AP90), the varus-valgus rotation at 0 and 30 degrees of knee flexion (VV0 and VV30) and the dynamic laxity on the pivot-shift test (PS), which was determined through the anterior displacement of the lateral tibial compartment (APlat) and posterior acceleration of the lateral tibial compartment during tibial reduction (ACC). Data from laxity before and after MAT were compared through paired t-test (p < 0.05). RESULTS After medial MAT, there was a significant decrease in tibial translation of 3.1 mm (31%; p = 0.001) for AP30 and 2.3 mm (27%; p = 0.020) for AP90, a significant difference of 2.5° (50%; p = 0.002) for VV0 and 1.7° (27%; p = 0.012) for VV30. However, medial MAT did not determine any reduction in the PS kinematic data. Lateral MAT determined a significant decrease in the tibial translation of 2.5 mm (38%; p < 0.001) for AP30 and 1.9 mm (34%; p = 0.004) for AP90 as well as a significant difference of 3.4° (59%; p < 0.001) for VV0 and of 1.7° (23%; p = 0.011) for VV30. There was also a significant reduction of the PS of 4.4 mm (22%; p = 0.028) for APlat and 384.8 mm/s2 (51%; p = 0.005) for ACC. CONCLUSION MAT with soft-tissue fixation results in a significant laxity reduction in an in-vivo setting. Medial MAT improved knee kinematics by determining a significant reduction with particular emphasis on AP translation and VV manoeuvre. Conversely, Lateral MAT determined a massive reduction of the PS and a mild decrease of the AP translation and VV manoeuvre. STUDY DESIGN Controlled laboratory study.

Abstract
BACKGROUND Knee laxity increases with medial meniscectomy in anterior cruciate ligament (ACL)-reconstructed knees; however, the biomechanical effect of an additional lateral extra-articular tenodesis (LET) is unknown. PURPOSE/HYPOTHESIS The purpose of this study was to determine the kinematic effect of a LET in knees that underwent combined ACL reconstruction (ACL-R) and partial medial meniscus posterior horn (MMPH) meniscectomy. It was hypothesized that the addition of LET would reduce laxity in the ACL-reconstructed knee. STUDY DESIGN Controlled laboratory study. METHODS Ten fresh-frozen human cadaveric knees (mean age, 41.5 years) were tested using a robotic system under 3 loads: (1) 89.0 N of anterior tibial (AT) load, (2) 5 N·m of internal rotation (IR) tibial torque, and (3) a simulated pivot shift-a combined valgus of 7 N·m and IR torque of 5 N·m-at 0°, 15°, 30°, 45°, 60°, and 90° of knee flexion. Kinematic data were acquired in 4 states: (1) intact, (2) ACL-R, (3) ACL-R + partial MMPH meniscectomy (MMPH), and (4) ACL-R + partial MMPH meniscectomy + LET (MMPH+LET). RESULTS In response to AT loading, there was a significant increase seen in AT translation (ATT) in the MMPH state at all knee flexion angles compared with the ACL-R state, with the highest increase at 90° of knee flexion (mean difference, 3.1 mm) (P < .001). Although there was a significant decrease in ATT at 15° of knee flexion with MMPH+LET (P = .022), no significant differences were found at other knee flexion angles (P > .05). In MMPH with IR torque, a significant increase was observed in IR at all knee flexion angles except 90° compared with the ACL-R state (range, 2.8°-4.9°), and this increase was significantly decreased at all flexion angles with the addition of LET (range, 0.7°-1.6°) (P < .05). CONCLUSION Performing a partial MMPH meniscectomy increased ATT and IR in response to AT and IR loads compared with the isolated ACL-R state in a cadaveric model. However, when the LET procedure was performed after partial MMPH meniscectomy, a significant decrease was seen at all knee flexion angles except 90° in response to IR and torque, and a significant decrease was seen at 15° of knee flexion in response to AT load. CLINICAL RELEVANCE LET may be a useful adjunct procedure after ACL-R with partial MMPH meniscectomy to reduce knee laxity.

Abstract
OBJECTIVE To observe the effect of acupuncture exercise therapy synchronizing isokinetic muscle strength training on the motor function, stability and proprioception of knee joint, as well as the anxiety emotion in patients after meniscectomy under arthroscopy. METHODS A total of 70 patients after meniscectomy under arthroscopy were randomized into an observation group (35 cases, 2 cases were eliminated, 2 cases dropped off) and a control group (35 cases, 2 cases were eliminated, 1 case dropped off). Acupuncture was applied at Chize (LU 5), Neixiyan (EX-LE 4), Dubi (ST 35),Yanglingquan (GB 34), etc. on the affective side in the two groups. After 30 min, the needles of the knee joint area were withdrew, while the needle at elbow was continuously retained, the observation group was given acupuncture exercise therapy synchronizing isokinetic muscle strength training, and the control group was given conventional acupuncture exercise therapy. The treatment was given once a day, 7-day treatment was taken as one course, and totally 4 courses were required in the two groups. Before and after treatment, the knee joint Lysholm score, the knee joint isokinetic muscle strength flexion/extension ratio (H/Q), joint position sense measurement (JPS) and Hamilton anxiety scale (HAMA) score were compared in the two groups. RESULTS After treatment, the knee joint Lysholm scores and H/Q were increased compared with those before treatment in the two groups (P<0.001), and the knee joint Lysholm score and H/Q in the observation group were higher than those in the control group (P<0.001); the JPS and HAMA scores were decreased compared with those before treatment in the two groups (P<0.001), the JPS and HAMA score in the observation group were lower than those in the control group (P<0.05). CONCLUSION Acupuncture exercise therapy synchronizing isokinetic muscle strength training can effectively improve the motor function, stability and proprioception of knee joint, as well as the anxiety emotion in patients after meniscectomy under arthroscopy.

Abstract
Osteoarthritis (OA) affects >500 million people globally, and this number is expected to increase. OA management primarily focuses on symptom alleviation, using non-steroidal anti-inflammatory drugs, including Celecoxib. However, such medication has serious side effects, emphasizing the need for disease-specific treatment. The meniscectomy and cranial cruciate ligament transection (CCLx)-treated beagle dog was used to investigate the efficacy of a modified-release formulation of SKI306X (SKCPT) from Clematis mandshurica, Prunella vulgaris, and Trichosanthes kirilowii in managing arthritis. SKCPT's anti-inflammatory and analgesic properties have been assessed via stifle circumference, gait, incapacitance, histopathology, and ELISA tests. The different SKCPT concentrations and formulations also affected the outcome. SKCPT improved the gait, histopathological, and ELISA OA assessment parameters compared to the control group. Pro-inflammatory cytokines and matrix metalloproteinases were significantly lower in the SKCPT-treated groups than in the control group. This study found that SKCPT reduces arthritic lesions and improves abnormal gait. The 300 mg modified-release formulation was more efficacious than others, suggesting a promising approach for managing OA symptoms and addressing disease pathogenesis. A high active ingredient level and a release pattern make this formulation effective for twice-daily arthritis treatment.

Abstract
Degenerative meniscus tears (DMTs) are prevalent findings in osteoarthritic knees, yet current treatment is mostly limited to arthroscopic partial meniscectomy rather than regeneration, which further exacerbates arthritic changes. Translational research regarding meniscus regeneration is hindered by the complex, composite nature of the meniscus which exhibit a gradient from inner cartilage-like tissue to outer fibrous tissue, as well as engineering hurdles often requiring growth factors and cross-linking agents. Here, a meniscus zonal tissue gradient is proposed using zone-specific decellularized meniscus extracellular matrix (DMECM) and autologous synovial mesenchymal stem cells (SMSC) via self-aggregation without the use of growth factors or cross-linking agents. Combination with zone-specific DMECM during self-aggregation of MSCs forms zone-specific meniscus tissue that reflects the respective DMECM harvest site. The implantation of these constructs leads to the regeneration of meniscus tissue resembling the native meniscus, demonstrating inner cartilaginous and outer fibrous characteristics as well as recovery of native meniscal microarchitecture in a porcine partial meniscectomy model at 6 months. In all, the findings offer a potential regenerative therapy for DMTs that may improve current partial meniscectomy-based patient care.

Abstract
BACKGROUND Concomitant lateral meniscal (LM) injuries are common in acute anterior cruciate ligament (ACL) ruptures. However, the effect of addressing these injuries with various treatment methods during primary ACL reconstruction (ACLR) on patient-reported outcomes (PROs) is unknown. Therefore, the purpose of this study was to compare postoperative Knee injury and Osteoarthritis Outcome Score (KOOS) at 2-, 5-, and 10-years after isolated primary ACLR to primary ACLR with various treatment methods to address concomitant LM injury. METHODS This study was based on data from the Swedish National Knee Ligament Registry. Patients ≥ 15 years with data on postoperative KOOS who underwent primary ACLR between the years 2005 and 2018 were included in this study. The study population was divided into five groups: 1) Isolated ACLR, 2) ACLR + LM repair, 3) ACLR + LM resection, 4) ACLR + LM injury left in situ, and 5) ACLR + LM repair + LM resection. Patients with concomitant medial meniscal or other surgically treated ligament injuries were excluded. RESULTS Of 31,819 included patients, 24% had LM injury. After post hoc comparisons, significantly lower scores were found for the KOOS Symptoms subscale in ACLR + LM repair group compared to isolated ACLR (76.0 vs 78.3, p = 0.0097) and ACLR + LM injury left in situ groups (76.0 vs 78.3, p = 0.041) at 2-year follow-up. However, at 10-year follow-up, no differences were found between ACLR + LM repair and isolated ACLR, but ACLR + LM resection resulted in significantly lower KOOS Symptoms scores compared to isolated ACLR (80.4 vs 82.3, p = 0.041). CONCLUSION The results of this study suggest that LM injury during ACLR is associated with lower KOOS scores, particularly in the Symptoms subscale, at short- and long-term follow-up. However, this finding falls below minimal clinical important difference and therefore may not be clinically relevant. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND The optimal treatment option for meniscus root tears is still challenging, and whether the meniscus root repair ultimately can arrest or delay osteoarthritic changes is still a concern. PURPOSE/HYPOTHESIS The purpose of this study was 2-fold: (1) to describe and compare histopathologic findings of 3 different therapeutic options for medial meniscus posterior root tear: nonoperative management, partial meniscectomy, and meniscus root repair; and (2) to test the hypothesis that meniscus root tears treated nonoperatively predispose to a lower risk of osteoarthritic progression compared with partial meniscectomy. STUDY DESIGN Controlled laboratory study. METHODS Posteromedial meniscus root tears were carried out in 39 New Zealand White rabbits. Animals were randomly assigned into 3 experimental groups: partial meniscectomy after root tear (PM; n = 13), root tears treated conservatively (CT; n = 13), and transtibial root repair (RR; n = 13). Contralateral limbs were used as healthy controls. The animals were euthanized at 16 weeks postoperatively; tissue samples of femoral and tibial articular cartilage were collected and processed for macro- and microscopic assessment to detect signs of early osteoarthritis (OA). Each sample was histopathologically assessed using the Osteoarthritis Research Society International grading and staging system. RESULTS Osteoarthritic changes were the hallmark in all 3 experimental groups. The RR group had the lowest scores for cartilage damage (mean, 2.5; range, 2-3), and the PM group exhibited higher and more severe signs of OA (mean, 16; range, 9-16) compared with the CT group (mean, 5; range, 4-6). The between-group comparison revealed significant differences, as the PM group showed a significantly higher rate of macro- and microscopic osteoarthritic changes compared with the RR (P < .001) and CT (P < .001) groups. The weightbearing area of the medial femoral condyle was the most severely affected, and tidemark disruption was evident in all tissue samples. CONCLUSION Meniscus root repair cannot completely arrest the histopathologic progression of knee OA but leads to significantly less severe degenerative changes than partial meniscectomy and nonoperative treatment. Partial meniscectomy leads to the most severe osteoarthritic progression, while stable radial tears left in situ have lower progression compared with partial meniscectomy. CLINICAL RELEVANCE Histologic assessment is an essential tool and metric for guiding and understanding osteoarthritic features, providing insight into the disease development and progression. This study provides histopathologic evidence on osteoarthritic progression after medial meniscus posterior root repair. This knowledge can help to set more realistic expectations and can lead to the future development of augmented techniques.

Abstract
CASE We report a case of delayed presentation of popliteal artery laceration after arthroscopic meniscectomy. Three weeks after the procedure, the patient developed severe calf pain, swelling over the popliteal fossa, and foot drop, despite a normal initial postoperative period. Clinical examination and radiological investigations suggested a massive hematoma in the popliteal fossa. A decision was made to explore the popliteal artery and drain the hematoma after consultation with the vascular surgeon. A laceration was noted, and it was repaired. CONCLUSION Orthopaedic surgeons should maintain a high index of suspicion regarding the possibility of this postoperative complication, especially after an arthroscopic meniscectomy.

Abstract
This retrospective study aimed to compare the effectiveness between concurrent meniscoplasty and conservative management on the asymptomatic side in children with unilaterally symptomatic bilateral discoid lateral meniscus operated on the symptomatic side in a tertiary level of clinical care. Patients aged under 14 with unilaterally symptomatic bilateral discoid lateral meniscus underwent arthroscopic meniscoplasty were eligible. Patients were either underwent meniscoplasty on the symptomatic side, with the asymptomatic side conservatively treated (group 1) or underwent meniscoplasty on both sides concurrently (group 2). Functional outcomes were evaluated using the Lysholm score and Ikeuchi score. Relative cost collected through the hospital data was applied by the Kruskal-Wallis test. The occurrence of symptoms was applied by the Kaplan-Meier model. A total of 50 patients (39 female and 11 male) were eligible. For the average Lysholm scores, groups 1 and 2 of the previously asymptomatic side were 90.86 ± 8.25 and 92.62 ± 8.68. For the symptomatic side, the Lysholm scores were 91.38 ± 8.90 and 95.71 ± 7.45. For the average cost of treatment, a significant difference was discovered between group 1 and 2 (P < .0001). The Kaplan-Meier survival analysis of the occurrence of symptoms showed no statistical difference between the 2 groups (P = .162), and the terminal survival rates in the 2 groups were 86.2% and 81.0%, respectively. Conservative treatment reached the same clinical outcomes as the concurrent meniscectomy, with a potential of longer mean survival time and lower demand of cost in treatment.

Abstract
INTRODUCTION Our main objective was to evaluate clinically and radiologically and compare patients who had undergone partial meniscectomy alone, with those who had received a partial meniscectomy in which a polyurethane implant was placed, with a minimum follow-up of 5 years. METHODS We performed a prospective cohort study. Patients were randomly distributed into Group A if they only received meniscectomy or Group B if they received meniscectomy plus a meniscal implant (Actifit®). We performed preoperative, postoperative, and 5-year-follow-up functional and radiological evaluations (magnetic resonance imaging). RESULTS Twelve patients (40%) were treated with meniscal implants (Group B); 18 (60%) were treated with a conventional meniscectomy (Group A). Tegner, Lysholm and KOOS scores were evaluated prior to surgery and at 5-year follow-up. Only the Lysholm score showed a significant difference between groups, with a score increase between the preoperative evaluation and the 5-year follow-up evaluation (p = 0.013). Preoperative and postoperative MRIs were both available in 19 cases (63.3%). Long-term follow-up MRIs were performed in 11 cases of group B. No significant differences were found in functional outcomes or MRI findings (WORMS cartilage score increase p = 0.360). Although total reabsorptions of the collagen meniscus implant were not statistically significant in younger patients, a tendency towards a higher reabsorption process was seen in older patients (p = 0.015). CONCLUSION The placement of a polyurethane implant after a wide meniscectomy is not accompanied by a chondroprotective effect over time. There is no functional difference between implant placement and isolated meniscectomy. There is a discrepancy between good clinical results and radiologic appearance of these implants and their underlying cartilage. LEVEL OF EVIDENCE II, therapeutic study.

Abstract
OBJECTIVE The objective of this study is to establish which patient and lesion characteristics are related to the clinical outcome after microfracture of cartilage defects in the knee. STUDY DESIGN Systematic review. METHODS After preregistration, PubMed, Embase, and Cochrane were searched for studies that analyzed prognostic factors for the outcome of microfracture treatment in the knee. The criteria for inclusion were outcome measured using Patient-Reported Outcome Measures (PROMs), a clinical study with ≥10 participants receiving microfracture, and a minimal follow-up period of 1 year. RESULTS For none of the investigated prognostic factors, effect size reporting was sufficiently homogeneous to conduct a meta-analysis. However, a majority of the included studies identified higher age, larger lesion size, longer preoperative symptom duration, and previous surgery on the ipsilateral knee, especially meniscectomy and anterior cruciate ligament reconstruction, as factors that are reported to be correlated to a less favorable outcome. A lesion location that does not include the trochlea or the patellofemoral joint and is not weightbearing, a nondegenerative mechanism of injury, and a single lesion were reported as factors that predict a favorable outcome. As to gender, body mass index, preoperative activity level, smoking, and concomitant knee surgery, the included articles were inconclusive or no effect was reported. CONCLUSIONS Several factors correlated with the clinical result after microfracture treatment. However, the information on the effect sizes of the influence on clinical outcome is incomplete due to poor reporting. Large-scale registries or pooling of homogeneous, well-reported data is needed to work toward prognostic models. That would be an important step toward personalized treatment.

Abstract
BACKGROUND Previous studies have investigated the impact of social determinants of health, such as the type of healthcare insurance and household income, on children and adolescents with ACL tears. However, despite the increasing incidence of ACL injury in young patients and a substantial proportion of families who may prefer languages other than English, the relationship between language and clinical care remains unclear. QUESTIONS/PURPOSES To investigate the relationship between language and the care of children and adolescents with ACL tears, we asked: (1) Is a preferred language other than English (PLOE) associated with a delay between ACL injury and surgery? (2) Is a PLOE associated with a greater odds of a patient experiencing a meniscal tear and undergoing a meniscectomy than in those who prefer English? METHODS We treated 591 patients surgically for ACL injuries between 2011 and 2021. Of those, we considered patients aged 18 years or younger who underwent primary ACL reconstruction for this retrospective, comparative study. Five percent (31 of 591) of patients were excluded because the date of injury was not clearly documented, 2% (11 of 591) were revision reconstructions, and 1% (6 of 591) underwent procedures that were intentionally delayed or staged, leaving 92% (543 of 591) for analysis. The mean age was 16 ± 2 years, and 51% (276 of 543) of patients were boys. The family's preferred language was noted, as were demographic data, time between injury and surgery, and intraoperative findings. A language other than English was preferred by 21% (113 of 543) of patients. Of these, 94% (106 of 113) preferred Spanish. In a univariate analysis, we used independent-samples t-tests, Mann-Whitney U-tests, and Fisher exact tests, as appropriate. Purposeful-entry multivariable regression analyses were used to determine whether PLOE was associated with increased time to surgery, concomitant meniscus injury, or performance of meniscectomy while adjusting for confounding variables. Variables were included in multivariable models if they met the threshold for statistical significance in univariate testing (p < 0.05). RESULTS The median time between injury and ACL reconstruction was shorter in families who preferred English compared with those with a PLOE (69 days [IQR 80] versus 103 days [IQR 107)]; p < 0.001). After controlling for potentially confounding variables like insurance and age, we found that patients whose families had a PLOE had greater odds of undergoing surgery more than 60 days after injury (OR 2.2 [95% CI 1.3 to 3.8]; p = 0.005) and more than 90 days after injury (OR 1.8 [95% CI 1.1 to 2.8]; p = 0.02). After controlling for insurance, age, and other factors, PLOE was not associated with surgical delay beyond 180 days, concomitant meniscal tears, or performance of meniscectomy. CONCLUSION In this study of children and adolescents undergoing primary ACL reconstruction, patients whose families prefer a language other than English experienced a longer delay between injury and surgery. In areas with a large proportion of families with a PLOE, partnerships with primary care clinicians, emergency departments, schools, athletic teams, and community organizations may improve efficiency in the care of children with ACL injuries. Clinicians proficient in other languages, reliable interpreter services, and translated references and resources may also be impactful. Our results suggest a need for further research on the experiences, needs, and long-term outcomes of these patients, as well as the association of preferred language with results after surgery. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
PURPOSE Meniscal scaffold implants have gained interestas a therapeutic alternative for irreparable partial meniscal defects and post-meniscectomy syndrome. However, the effect of laterality on outcomes is unclear. This study aimsto assess the hypothesis that lateral meniscal scaffold implants have worse clinical or survival outcomes compared with medial scaffold implants. METHODS The study was performedaccording to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and registered with PROSPERO. Three databases (PubMed, Embase, Scopus) were searched from date of database establishment to 21 January 2022. Human studies reporting clinical or survival outcomedata specific to the medial or lateral meniscal scaffold implant were included. Random-effects model was used to analyse survival outcome data. RESULTS Ten studies comprising 568 patients (mean age 29.2-40 years, follow up duration 1-14 years) were included. There were 483 medial and 85 lateral meniscal scaffold implants. Amongst two studies directly comparing the survival rate of medial and lateral meniscal scaffolds, there was no significant difference in survival rates between medial and lateral meniscus scaffolds (hazard ratio = 1.24, 95 % confidence interval: 0.51-3.03, P = 0.63). There were no consistent statistically significant differences between medial and lateral meniscal scaffolds in terms of postoperative Visual Analog Scale pain,Tegner Activity, Lysholm, International Knee Documentation Committee, Knee Injury and Osteoarthritis Outcome, and Knee Society Scores. CONCLUSION Despite anatomical and biomechanical differences between the medial and lateral meniscus, there are no significant differences in clinical outcomes or survival rates between medial and lateral meniscal scaffold implants for irreparable partial meniscal defects at short- or mid-term follow up. Lateral meniscal scaffold implants are therefore non-inferior to medial meniscal scaffold implants.

Abstract
BACKGROUND The purpose of this study was to evaluate for changes in the incidence of arthroscopic meniscal procedures, especially meniscal allograft transplantation (MAT) in New York State (NYS) between 2005 to 2014. METHODS The New York Statewide Planning and Research Cooperative Systems (SPARCS) database was queried from 2005 through 2014 to identify patients undergoing meniscetomies, meniscal repairs, and MAT. Patients were followed longitudinally to determine the incidence of subsequent ipsilateral knee procedures. The impact of patient demographics and surgeon volume on reoperation was explored. RESULTS From 2005 through 2014, there were 524,737 arthroscopic meniscal procedures. Of these, there were 510,406 meniscectomies, 14,214 meniscal repairs, and 117 MATs. The number of MATs increased 15.5% per year, with the largest increase being between 2013 to 2014 (an increase of 86.5%). Average MAT patient age was 29.8 ± 11.1 years; 65.0% of patients were male; 66% were Caucasian; 84% were privately-insured; and 23% of surgeons met the criteria for high-volume (five or more MATs in a year). A total of 25.6% (30/117) patients underwent subsequent surgery; 26 patients underwent knee procedures at mean of 18.9 ± 18.3 months after initial MAT, the most common of which were ipsilateral meniscectomies (19/26). Four patients underwent total knee arthroplasty (TKA) at a mean of 21.0 ± 9.2 months after initial MAT. Patients undergoing TKA after MAT were significantly older (42.0 ± 15.0 years vs, 29.3 ± 10.7 years; p = 0.0242) than patients who did not. Neither demographics nor surgeon volume were statistically significant factors for undergoing subsequent surgery (p > 0.05). CONCLUSION Meniscal allograft transplantation, though relatively uncommon, is being performed with greater frequency in NYS. Surgeons should counsel patients regarding the likelihood of requiring subsequent knee surgery after MAT, with repeat arthroscopic partial meniscectomy being the most commonly performed procedure.

Abstract
INTRODUCTION There are no meta-analytical data in the long term for comparing surgery and exercise for meniscal tear. The aim of this study is to compare the effectiveness of exercise versus arthroscopic partial meniscectomy (APM) plus exercise for degenerative meniscal tears (DMT) in knee function at 5-year follow-up. MATERIALS AND METHODS A systematic search of Medline, EMBASE, Web of Science, SciELO, SPORTDiscus, Scopus, and Cochrane Library was performed. The studies were included if they were randomized controlled trials performed in patients aged ≥ 18 years with DMT, that compared physical therapy to APM at 5-year follow-up, and reported at least one outcome measure of knee function/disability. Risk of bias was analyzed with the Cochrane RoB-2 tool and certainty of evidence with GRADE recommendations. A random effects model meta-analysis was performed. RESULTS 3743 articles were identified and 4 met the criteria. Three had low risk of bias and one had some concerns. There were no significant between-group differences, in within-group changes from baseline to 5-year, on the Knee Injury and Osteoarthritis Outcome Score pain (- 2.28; 95% CI - 5.41 to 0.84), symptoms (- 0.24; 95% CI - 4.13 to 3.64), activities of daily living (- 2.16; 95% CI - 6.16 to 1.83) and quality of life (- 3.98; 95% CI - 9.05 to 1.10). There was a significant difference in support of APM plus exercise for sport/recreation (- 9.28; 95% CI - 18.28 to - 0.29). Leave-one-out sensitivity analysis revealed a non-significant difference in sport/recreation (- 5.05; 95% CI - 12.04 to 1.94). There were no differences in other patient-reported outcome measures. CONCLUSION Moderate certainty of evidence suggests that the addition of APM to an exercise program adds no benefits in knee function at 5-year follow-up.

Abstract
Physiotherapy includes treatment to restore and optimize mobility after surgery, injury, disease, and/or degeneration. Based on assessments throughout the recovery process from visual observations of movement, exercises are prescribed to perform at home between clinic sessions. Although technical advances have facilitated remote communication between therapists and patients, accurate assessment of at-home exercises is challenged by a lack of direct observation. The current study advances remote assessment tools to assess key lower body exercises prescribed in a case study following recovery from arthroscopic partial meniscectomy (APM). Using Vicon motion capture, recovery metrics related to range of motion, strength, and gait function were extracted. Peak knee flexion angle on the operated leg during heel slide increased from 91.61° ± 4.17° to 127.42° ± 2.35° (p<0.05), although significant differences were found compared to the non-operated leg at Day 6 (138.19° ± 5.44°, p<0.05). Repetition times in heel slide and leg raise exercises on the affected leg decreased from Day 2 (2.74s) to Day 6 (1.07s), indicating strength recovery. Step length asymmetry decreased by 61.22% and step width asymmetry decreased by 41.75% from Day 2 to Day 6 post surgery, demonstrating improved gait function. This work presents a sample of automated recovery metrics that can be used for therapists to assess rehabilitation and inform the recovery process. Implications of the study findings on remote assessment using wearables are discussed. This work presents kinematics based quantifiable lower limb rehabilitation metrics to assess recovery objectives (e.g., knee flexion angle to assess knee range of motion) used by clinicians to inform recovery remotely.

Abstract
INTRODUCTION The extent to which physical therapy (PT) is used after meniscectomy is unknown. The objective of this study was to estimate the extent to which PT is implemented after meniscectomy and to identify factors associated with its utilization. METHODS The Mariner PearlDiver database was queried to identify patients who underwent uncomplicated meniscectomy. The number of PT visits for each patient was tabulated. Logistic regressions were used to compare demographic factors associated with no use of PT and use of nine or more PT visits. RESULTS In total, 92,291 patients met inclusion criteria. Of these patients, 72.21% did not use PT and 27.8% used 1 or more PT visits. Of the patients who used PT, 19.76% had 1 to 8 PT visits and 8.03% had 9 or more PT visits. Older age and noncommercial insurance types were associated with no PT use. Male sex, Medicaid, and Medicare were associated with markedly lower odds of increased PT utilization. CONCLUSION PT is used in the minority of the time after meniscectomy. Among patients who do use PT, however, notable variation exists in the amount of PT visits used. Patient age, sex, insurance status, and geographic variables were independently associated with PT utilization.

Abstract
Electromyographic biofeedback (EMG-BF) is a therapeutic technique that has been used successfully in the rehabilitation of injuries. Although it has been applied to athletes, its use in this field is not very widespread. The objective of this study is to analyze its effectiveness in the recovery of electromyographic activity of the quadriceps after meniscectomy, evaluated through isometric contraction of the vastus lateralis. The sample comprised ten professional footballers in the Spanish League (2nd Division A) who had previously suffered a meniscus injury in their knee and had undergone a meniscectomy. The intervention consisted of EMG-BF treatment lasting between 6 and 10 sessions. The electromyographic signal was recorded using a Thought Technology ProComp Infiniti 8-channel biofeedback unit with a sampling rate of 2048 samples/second. For each session, a within-subject ABA design of 6 or 10 trials per session was used, with three pre- and three post-measures, which determined the gain for each session. The results indicated (1) improvements in all cases, (2) EMG-BF was effective, (3) the working model was statistically significant with an explained variance of between 67% and 75%, and (4) the generalizability analysis showed that the results are reliable and generalizable. The results indicate that EMG-BF is effective in neuromuscular rehabilitation after this type of intervention.

Abstract
ABSTRACT Meniscus root tears are important to recognize early given their potentially devastating consequences on joint health. This injury results in the lost ability of the meniscus to transfer axial loads into hoop stress; therefore, it is functionally equivalent to a complete meniscectomy. This causes rapid progression of osteoarthritis and increased need to total knee arthroplasty in a previously healthy joint. Despite these consequences, root tears have only been discussed in the orthopedic literature in the last 10 to 15 years and have not been routinely integrated into nonoperative sports medicine education. It is important for all nonoperative sports medicine providers to properly diagnose and triage this injury early in its course to maximize joint preservation efforts. The goal of this manuscript is to review the anatomy, presentation, natural history, imaging, and treatment options for meniscal root tears.

Abstract
CASE A 48-year-old man presented with persistent right knee pain 15 years after an arthroscopic partial meniscectomy. Right knee radiography was remarkable for a retained scalpel blade in the knee joint. The retained scalpel blade was completely removed from the affected knee arthroscopically; however, the patient's knee pain did not improve with 6 weeks of physically therapy. CONCLUSIONS Arthroscopy surgeons should be cognizant of the risk for retained implants and emphasize the importance of a postprocedure surgical equipment count, and the merits of an x-ray if surgical count discrepancies are detected, or the patient has persistent joint pain despite rehabilitation.

Abstract
The aim of this paper was to investigate whether job characteristics are associated with time interval for return to former professional activity (return to work, RTW) after arthroscopic partial meniscectomy (APM). A retrospective study was carried out in a sample of 63 patients in working age who underwent an APM between July 2018 and July 2020. The following preoperative characteristics were assessed: age at surgery, meniscal side, sex, physical job demands (white versus blue collar worker), telework and work status (salaried versus self- employed). A linear regression analysis was used to study the association between job characteristics and RTW interval adjusted for socio-demographic and medical (meniscal side) factors. Telework was most strongly associated with interval for RTW (p <0,001, adjusted R Square: 20,8). The results suggested that telework supports early RTW independently of sociodemographic and medical factors. This study supported the need for a tailormade approach in the prescription of sick leave.

Abstract
PURPOSE To evaluate correlations between preoperative pain sensitivity and postoperative analgesic consumption together with pain perception shortly after arthroscopic partial meniscectomy in non-arthritic knees. METHODS Ninety-nine patients who underwent primary arthroscopic meniscectomy were prospectively divided into three postoperative treatment groups that were prescribed with betamethasone injection (at the end of surgery), oral celecoxib or rescue analgesia (control). Preoperative pain sensitivity was evaluated by pain sensitivity questionnaires (PSQ). Patients were followed for the first three postoperative weeks to evaluate knee injury and osteoarthritis outcome score (KOOS) pain scores and analgesics consumption. Statistical analysis included correlations among preoperative pain sensitivity, postoperative pain levels and analgesics consumption. A receiver operating characteristic curve was plotted to investigate the cutoff values of the PSQ score to predict insufficient postoperative pain reduction. RESULTS There were no differences at baseline among all study groups in age, sex, BMI, level of activity, comorbidities and surgical findings. At the final follow-up, KOOS pain scores improved in all groups (p < 0.001). Mean final KOOS pain scores were 76.1 ± 15.2 for the betamethasone group, 70.8 ± 12.6 for the celecoxib group and 78.7 ± 11.6 for the control group. No differences in scores were observed among groups (n.s.). In the control group, a negative correlation was observed between PSQ score and KOOS-pain scores at the end of the follow-up in addition to a positive correlation between PSQ score and rescue analgesia consumption at the first postoperative week. The optimal cutoff value for PSQ score to predict insufficient improvement in KOOS-pain subscale was 5.0 points. CONCLUSIONS A cutoff value of pain sensitivity questionnaire score above 5.0 points was determined to identify patients with higher sensitivity to pain who underwent arthroscopic partial meniscectomy. These patients reported relatively increased pain and consumed more rescue analgesics postoperatively unless treated with a single intraoperative corticosteroids injection or oral non-steroidal anti-inflammatories. Therefore, surgeons can use pain sensitivity questionnaire score as a preoperative tool to identify patients with high sensitivity to pain and customize their postoperative analgesics protocol to better fit their pain levels.

Abstract
Background The Covid-19 pandemic has created the largest disruption of education in history. In a response to this, we aimed to evaluate the knee arthroscopy learning curve among medical students and orthopaedic residents. Methods An arthroscopy simulator was used to compare the learning curves of two groups. Medical students with any prior knowledge of arthroscopy (n=24) were compared to a residents group (n=16). Analyzed parameters were “time to complete a task,” assessment of the movement of tools and values scoring damage to the surrounding tissues. Results After several repetitions, both groups improved their skills in terms of time and movement. Residents were on average faster, had less camera movement, and touched the cartilage tissue less often than did students. Students showed a steeper improvement curve than residents for certain parameters, as they started from a different experience level. Conclusion The participants were able to reduce the time to complete a task. There was also a decrease in possible damage to the virtual surrounding tissues. In general, the residents had better mean values, but the students had the steeper learning curve. Particularly less experienced surgeons can especially train their hand–eye coordination skills required for arthroscopy surgery. Training simulators are an important training tool that supplements cadaveric training and participation in arthroscopic operations and should be included in training.

Abstract
Osteoarthritis of the knee is often accompanied by degeneration of the meniscus. Worldwide, the arthroscopic partial meniscectomy has been a standard of care for patients with knee pain in the presence a degenerative meniscal tear. However, in recent years, clinical studies have proven that a meniscectomy is not effective in the osteoarthritic knee. Physiotherapy is often as effective. The updated Dutch guidelines for meniscal tears therefore recommend an arthroscopic partial meniscectomy or fixation in case of a locked knee and for traumatic meniscal tears in younger patients. There also is an indication for a meniscectomy after failure of conservative treatment in case of a symptomatic meniscal tear in the absence of osteoarthritis.

Abstract
This study aims to investigate the effects and mechanisms of parathyroid hormone [1-34] (PTH1-34) on TNF-α-stimulated mice chondrocytes, as well as cartilage from a meniscus injury induced osteoarthritis (MIO) mice model. The C57BL/6J mice received medial meniscectomy, and then administrated with PTH1-34. The results showed that PTH1-34 administration decreased secondary allodynia and the pain-related transcripts. The IHC, ELISA, Micro-CT imaging and histopathology analysis revealed the significantly improved subchondral plate thickness and bone porosity, the reduced pro-inflammatory cytokines in serum and joint fluid. In vitro, mice chondrocyte was treated with TNF-α or co-cultured with synovial cells. The results showed that TNF-α markedly upregulated the MMP13 expression, and the ERK1/2, NF-κB or PI3K signaling pathway inhibitors could reverse the induction effect of TNF-α on expression of MMP13 in chondrocytes. PTH1-34 alone has no effect on the expression of MMP13 and NF-κB signaling pathways, but the PTH1-34 could reverse the induction effect of TNF-α on MMP13 expression and NF-κB signaling pathway activation in chondrocytes. In addition, PTH1-34 administration inhibited the expression of TNF-α and MMP13, and chondrocyte viability, while the PKA repressor reversed the effect of PTH1-34 in chondrocytes co-cultured with synovial cells. In conclusion, PTH1-34 has an obvious analgesic and anti-inflammatory effect, inhibits the matrix synthesis and alleviates the progression of osteoarthritis. In vitro, PTH1-34 inhibited TNF-α expression and antagonized TNF-α-induced MMP13 expression via the PKA pathway and the NF-κB signaling pathways, respectively.

Abstract
Meniscal pathology is one of the most common structural knee issues seen and managed by the orthopaedic surgeon. An ever-evolving armamentarium of management options exists that are geared toward the elimination of symptoms and restoration of normal knee function. A common theme among these management options is to preserve meniscal tissue whenever possible through repair or minimization of meniscal excision, as the literature has shown that the loss of meniscal tissue can significantly alter the distribution of forces and contact stresses on knee articular cartilage, thus predisposing the joint to degenerative osteoarthritis. In the setting of meniscal injuries or insufficiency, various advances in repair techniques, use of meniscal allografts, and use of biologic adjuvants have been reported to help preserve and/or attempt to restore the native kinematic properties of the knee. It is important to explore meniscal function, its associated pathologies, and currently available treatment options that are supported by short-term and long-term clinical data.

Abstract
Degenerative meniscal lesions (DML) typically occur in middle-aged or elderly patients without any history of significant acute trauma. Its prevalence increases with age and are associated with knee osteoarthritis (OA). The most frequent orthopaedic treatment is arthroscopic partial meniscectomy (APM) to relieve pain and functional deficit associated with DML. Nevertheless, several randomised controlled clinical trials recommed against APM as the first-line treatment for managing knee pain in patients affected by DML and no radiographic knee OA that should be reserved for cases of failure after 3 month conservative therapy or earlier in patients with signficant knee mechanical symptoms.

Abstract
Optical coherence tomography (OCT) is an attractive tool for evaluating cartilage. We developed an OCT system that reconstructs and analyzes a three-dimensional (3D) OCT image by determining the cartilage surface and cartilage-bone boundary from the image taken with currently available OCT devices. We examined the usefulness of 3D renderings of OCT images. In a rat meniscectomized model, the tibia was harvested after 0, 2, 4, or 8 weeks (n = 6). We scanned 300 slices in the y-plane to cover a 4 × 3 × 6-mm section (x-plane; 10 µm × 400 pixels, y-plane; 10 µm × 300 pixels, z-plane; 12.66 µm × 500 pixels) of the medial tibial cartilage. The cartilage surface line and the cartilage-bone boundary were plotted semi-automatically. Slices from 300 two-dimensional (2D) sequential images were systematically and visually checked and corrected, as necessary. We set a region of interest in the cartilage and quantified the cartilage volume in the 3D image. The Osteoarthritis Research Society International (OARSI) histological score was also obtained. The cartilage volume determined using 3D OCT images was 0.291 ± 0.022 mm3 in the normal, 0.264 ± 0.009 mm3 at 2 weeks, 0.210 ± 0.012 mm3 at 4 weeks, and 0.205 ± 0.011 mm3 at 8 weeks. The cartilage volume significantly decreased at 4 and 8 weeks and was significantly correlated with the OARSI histological score (r = -0.674; P = .002). Although the 3D image information could be obtained from the 2D images, the 3D OCT images provided easier-to-understand information because the 3D reconstructed cartilage provided information about the smoothness of the surface, the area, and depth of the defect at a glance.

Abstract
Medial meniscal root tears are biomechanically similar to a total meniscectomy. Repair is clinically indicated and supported by evidence. Increased contact pressures can result in cartilage degeneration and early onset of osteoarthritis. Once diffuse grade 3 or 4 osteoarthritis has settled in, repair may not be indicated anymore. Combining medial meniscal root repair with a high tibial osteotomy for grade 3 or 4 medial-compartment osteoarthritis is not beneficial, and osteotomy alone provides very similar clinical outcomes at 2 years. Meniscal healing was observed in only 18% of patients, and the rate of "cartilage recovery" during second-look arthroscopy was between 8% and 24%. The low sample size, short follow-up, and historical control group limit the validity and generalizability of these conclusions.

Abstract
PURPOSE To investigate patient return to sport and satisfaction after meniscal allograft transplantation (MAT). METHODS Patients undergoing MAT using a bone bridge technique between 2013 and 2015 with minimum 2-year follow-up were retrospectively reviewed. They completed a survey regarding return to sport, satisfaction, and subsequent surgery in addition to patient-reported outcome measures. RESULTS Of 117 patients, 87 (74.4%) were available at an average follow-up of 3.64 years (range, 2.01-5.13 years). The mean age at the time of surgery was 28.99 ± 8.26 years. Lateral MAT was performed in 44 cases (50.6%); medial MAT, 42 (48.3%); and combined medial and lateral MAT, 1 (1.1%). Concomitant procedures were performed in 72 patients (82.7%) including cartilage restoration (n = 65, 74.7%), realignment (n = 9, 10.3%), and anterior cruciate ligament reconstruction (n = 9, 10.3%). Patients experienced significant improvement in the Lysholm score (P < .001), International Knee Documentation Committee score (P < .001), Knee Injury and Osteoarthritis Outcome Score (KOOS)-Quality of Life (P < .001), KOOS-Activities of Daily Living (ADL) (P < .001), KOOS-Pain (P < .001), KOOS-Sports (P = .001), KOOS-Symptoms (P = .003), Short Form 12 physical score (P < .001), and Veterans Rand-12 physical score (P < .001). Reoperation was performed in 26 patients (29.9%); failure occurred in 12 patients (13.8%; total knee arthroplasty in 1, unicompartmental arthroplasty in 2, and total meniscectomy in 9). Overall, 77.0% of patients were satisfied with their outcome. Prior to MAT, 82 patients (94.3%) participated in sporting activities; 62 patients (75.6%) returned to at least one sport at 12.58 ± 6.20 months postoperatively, with 30 (48.4%) reaching their preoperative level of intensity and 72 (87.8%) discontinuing at least one of their preoperative sports. The most common reasons for sports discontinuation postoperatively were prevention of further damage (73.6%), pain with activity (51.4%), fear of further injury (48.6%), surgeon recommendation (33.3%), and swelling with activity (30.6%). Patients were satisfied with their sports participation at a rate of 62.1%. CONCLUSIONS In a complex patient population undergoing arthroscopic MAT, 75.6% of patients were able to return to at least one sport at an average of 12.58 ± 6.20 months postoperatively. The level of sport declined, with 93.5% of patients restricting involvement to recreational sports after MAT and 48.4% returning to their preoperative level of activity intensity. In addition, 87.8% of patients reported discontinuing a sport in which they had participated preoperatively. The most common reasons for decreasing level of sport were prevention of further damage, pain or swelling with sports, and fear of further injury. The reoperation rate after MAT was 29.9%. Most patients were satisfied with the outcome of surgery, with 77.0% satisfied in general and 62.1% satisfied with their ability to play sports. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
Meniscectomy in a young active patient can lead to poor outcomes with pain, decreased function and long-term osteoarthritis. Meniscal allograft transplantation (MAT) has therefore been developed to address this issue. We now have 30 years of experience with this technique which is no longer considered experimental and new indications have been added. MAT allows restoration of joint biomechanics, pain relief, improvement in knee function and stability, and reduce cartilage degeneration. This is a comprehensive review of the role of menisci, the indications and principles of MAT, as well as these results.

Abstract
INTRODUCTION Meniscal tears are a common knee injury with an incidence of 60 per 100 000. Management of meniscal tears can include either non-operative measures or operative procedures such as arthroscopic partial meniscectomy (APM). Despite substantial research evaluating the effectiveness of APM in the recent past, little is known about the clinical course or the experiences of patients with a meniscal tear. AIM To summarise the short to long-term patterns of variability in outcome in patients with a meniscal tear.To summarise the evidence on patient experiences of meniscal tears. In particular, we will focus on patient experiences of treatment options, treatment pathways and their views of the outcomes used in meniscal tear research. METHODS AND ANALYSIS Two search strategies will be developed to identify citations from EMBASE, MEDLINE, AMED, CENTRAL, Web of Science and Sociofile. The date of our planned search is 14 August 2020. For the quantitative review we will identify studies reporting patient-reported outcome measures in patients after a meniscal tear. The standardised mean change will be used to assess the variation in size of response and summarise the overall response to each treatment option. All studies will undergo quality assessment using either the Cochrane risk of bias or the Newcastle-Ottawa tool.A qualitative systematic review will be used to identify studies reporting views and experiences of patients with a meniscal tear. All studies will be assessed using the Critical Appraisal Skills Programme tool and if sufficient data are present a meta-synthesis will be performed to identify first, second and third-order constructs. ETHICS AND DISSEMINATION Given the nature of this study, no formal ethical approval will be sought. Results from the review will be disseminated at national conferences and will be submitted to a peer-reviewed journal for publication. Lay summaries will be freely available via the study Twitter page. PROSPERO REGISTRATION NUMBER CRD42019122179.

Abstract
BACKGROUND The aging process is accompanied by several conditions that could affect the outcome of meniscal allograft transplantation (MAT). These conditions have made it difficult for clinicians to determine the effect of chronologic age on survivorship after MAT. HYPOTHESIS Advanced age does not have an adverse effect on survivorship of MAT when controlling for age-related factors, such as cartilage status and time from previous meniscectomy. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS The records of 264 consecutive patients who underwent primary medial or lateral MAT were reviewed. To check whether there was a difference in MAT survivorship according to age, a cutoff value was calculated from a time-dependent receiver operating characteristic curve. Survival rates, as well as clinical improvement as determined using the Lysholm score, were compared between groups divided by the cutoff value. Patients were matched for cartilage status and elapsed time from previous meniscectomy. Differences in survivorship and clinical outcomes were assessed between the matched groups. RESULTS A time-dependent receiver operating characteristic curve showed that the difference in MAT survivorship was maximized with a cutoff age of 43 years. Kaplan-Meier analysis showed a significant difference in MAT survivorship between the older and younger groups (log-rank test, P = .01). However, after matching for cartilage status and time from previous meniscectomy, which left 56 patients per group, there was no significant difference in MAT survivorship (log-rank test, P = .10) between the groups. Regarding clinical outcomes, the mean Lysholm scores were not significantly different between the older and younger groups (P = .19, before matching; P = .39, after matching). CONCLUSION MAT survivorship was more affected by age-related prognostic factors, such as cartilage status and time from previous meniscectomy, than age itself. Clinical outcomes did not show differences according to age, either.

Abstract
Whether to repair or resect meniscal tears remains a matter of controversy. In theory, partial meniscectomy increases contact pressure, which may result in progressive and early cartilage degeneration and early osteoarthritis. Meniscal preservation is the preferred treatment option, but only a small percentage of meniscal tears are suitable for repair. Two recent registry studies challenge this approach and suggest that partial meniscectomy has similar clinical outcomes in the short term. Whether these findings can be maintained in the long term remains to be seen.

Abstract
INTRODUCTION Arthroscopic partial meniscectomy (APM) after degenerative meniscus tears is one of the most frequently performed surgeries in orthopaedics. Although several randomised controlled trials (RCTs) have been published that showed no clear benefit compared with sham treatment or non-surgical treatment, the incidence of APM remains high. The common perception by most orthopaedic surgeons is that there are subgroups of patients that do need APM to improve, and they argue that each study sample of the existing trials is not representative for the day-to-day patients in the clinic. Therefore, the objective of this individual participant data meta-analysis (IPDMA) is to assess whether there are subgroups of patients with degenerative meniscus lesions who benefit from APM in comparison with non-surgical or sham treatment. METHODS AND ANALYSIS An existing systematic review will be updated to identify all RCTs worldwide that evaluated APM compared with sham treatment or non-surgical treatment in patients with knee symptoms and degenerative meniscus tears. Time and effort will be spent in contacting principal investigators of the original trials and encourage them to collaborate in this project by sharing their trial data. All individual participant data will be validated for missing data, internal data consistency, randomisation integrity and censoring patterns. After validation, all datasets will be combined and analysed using a one-staged and two-staged approach. The RCTs' characteristics will be used for the assessment of clinical homogeneity and generalisability of the findings. The most important outcome will be the difference between APM and control groups in knee pain, function and quality of life 2 years after the intervention. Other outcomes of interest will include the difference in adverse events and mental health. ETHICS AND DISSEMINATION All trial data will be anonymised before it is shared with the authors. The data will be encrypted and stored on a secure server located in the Netherlands. No major ethical concerns remain. This IPDMA will provide the evidence base to update and tailor diagnostic and treatment protocols as well as (international) guidelines for patients for whom orthopaedic surgeons consider APM. The results will be submitted for publication in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER CRD42017067240.

Abstract
Partial meniscectomy is a frequently performed treatment strategy for non-suturable meniscal tears. However, the meniscal volume which can be resected without compromising the load-bearing, shock-absorbing function of the meniscus remains a topic of ongoing research. The aim of this study was to calculate the medio-lateral meniscal volume ratio to estimate this volume. In 90 patients (98 pairs of menisci) without meniscal injury, medial and lateral menisci were segmented on MRI imaging and 3D surface models were created to calculate volume. The mean medial meniscal volume was 1928,9mm3 and the mean lateral meniscal volume was 1681,7mm3. A fixed ratio of the medial over the lateral meniscal volume was calculated to be 1,16. The standard deviation of the prediction errors based on this ratio equals 217mm3. This ratio seems a useful parameter in follow-up research to determine whether there is a critical volume which can be resected without post-operative pain and osteoarthritis.
