Displaced Posterior Cruciate Avulsion Fracture Fixation With Medial Collateral Ligament and Lateral Meniscus Injury Using Combined Open and Arthroscopic Methods.

Tibial-sided posterior cruciate ligament avulsion fractures are challenging injuries that often occur concomitantly in the setting of multiligament knee and other soft-tissue injuries. There is no consensus on the optimal surgical approach or timing of treatment for these injuries. This Technical Note describes the fixation of a displaced posterior cruciate ligament avulsion fracture with concomitant grade 3 medial collateral ligament injuries and bucket-handle lateral meniscus tears using open and arthroscopic techniques. This method allows the surgeon to address multiple pathologies in a single stage, although it requires strategic planning and rehabilitation considerations.

Medial quadriceps tendon femoral ligament reconstruction and medial patellofemoral ligament reconstruction have no significant differences in clinical outcomes for treatment of lateral patellar instability: a matched-cohort study.

OBJECTIVES: The purpose of this study was to compare clinical outcomes of medial quadriceps tendon-femoral ligament reconstruction (MQTFLR) and medial patellofemoral ligament reconstruction (MPFLR) among patients with recurrent lateral patellar instability. METHODS: A retrospective matched-cohort study was conducted involving patients who underwent MQTFLR or MPFLR with or without tibial tubercle osteotomy (TTO) from 2019 to 2021. Subjects were matched 1:1 on age, concomitant osteochondral allograft (OCA), concomitant TTO, and follow-up time. Measured outcomes included 90-day complications, Visual Analog Scale (VAS) knee pain, return to sport/work, Kujala score, Tegner score, and MPFL-Return to Sport after Injury (MPFL-RSI) score. Outcomes were compared between groups using Mann-Whitney U-test for continuous variables and Fisher's exact test for categorical variables. P-values <0.05 were considered significant. RESULTS: Ten MQTFLR patients (mean age 28.7 years, 80% female, mean follow-up 19.7 months) and ten MPFLR patients (mean age 29.1 years, 90% female, mean follow-up 28.3 months) were included in the study. One MQTFLR patient (10%) and three MPFLR patients (30%) underwent reoperation for postoperative arthrofibrosis. Postoperative VAS resting pain was not significantly different between the groups (MQTFLR mean 1.1, MPFLR mean 0.6, p â€‹= â€‹0.31). There were no significant differences in rates of recurrent subluxations (MQTFLR 20%, MPFLR 0%, p â€‹= â€‹0.47), return to sport (MQTFLR 50%, MPFLR 75%, p â€‹= â€‹0.61), return to work (MQTFLR 100%, MPFLR 88%, p â€‹= â€‹1.00), or MPFL-RSI pass rate (MQTFLR 75% vs. MPFLR 38%, p â€‹= â€‹0.31). CONCLUSION: There were no significant differences in knee pain and function, return to work, and rates of recurrent patellar instability between patients who underwent MQTFLR versus MPFLR, though these results should be interpreted with caution given the small sample size and potential selection bias. LEVEL OF EVIDENCE: III.

Segond fracture: an indicator for increased risk of lateral meniscus injury in patients with acute anterior cruciate ligament ruptures.

PURPOSE: The purpose of this study was to investigate the incidence and anatomic distribution of meniscus injury in patients who have sustained acute ACL injuries with and without concomitant Segond fracture. We hypothesized that patients who have sustained a torn ACL with a concomitant Segond fracture would have a higher incidence of lateral meniscal injuries than patients with an isolated ACL injury. METHODS: Patients who underwent ACL reconstruction from 2012 to 2022 were retrospectively reviewed. Segond fractures were identified on knee radiographs. Inclusion criteria were age 18-40, injury during sports activity, and reconstruction within 90 days of injury. Sports activity, anatomic location of meniscus injury, and meniscus treatment were documented. Multivariable regression was used to identify predictors of meniscus injury/treatment. RESULTS: There were 25 of 603 (4.1%) patients who had an ACL tear with concomitant Segond fracture. The incidence of lateral meniscus injury in the Segond group (72%) was significantly higher than in the non-Segond cohort (49%; p = 0.024). A significantly smaller proportion of medial meniscus injuries among patients with Segond fractures were repaired (23.1%) compared to the non-Segond group (54.2%; p = 0.043). Multivariate analysis found patients with Segond fractures to have increased odds of lateral meniscus injury (OR 2.68; [1.09, 6.60], p = 0.032) and were less likely to have medial meniscus injuries repaired (OR 0.35; [0.15, 0.81], p = 0.014). Additionally, males had increased odds of lateral meniscus injury (OR 1.54; [1.08 - 2.91], p = 0.017), which were more likely to require repair (OR 1.48; [1.02, 2.14], p = 0.038). CONCLUSIONS: Among acute ACL injuries, the incidence of lateral meniscus injury is greater among patients with Segond fractures. Patients with Segond fracture were less likely to undergo repair of medial meniscal injuries.

Posterior Cruciate Ligament Reconstruction Current Concepts Review.

Posterior cruciate ligament (PCL) injuries are a rare form of knee injury often seen in the setting of high energy polytraumas; however, these injuries can occur in isolation as well. Often, the posterolateral corner (PLC) is involved, which imparts further posterior translational and rotational instability to these injuries. While non-operative management is certainly a reliable option for low grade isolated PCL tears, high grade injuries with concomitant PLC involvement, additional intra-articular pathologies requiring operative management, multiligamentous injuries, or patients who have failed non-operative management require PCL repair or reconstruction. The current review focuses on the many facets of PCL reconstruction, including single versus double bundle reconstruction, tibial slope implications, graft selection, multiligamentous injury considerations, tunnel management, and onlay versus inlay tibial footprint creation. We conclude with a proposed algorithm in the management of this injury.

Patellar Instability Current Concepts and Controversies.

Recurrent patellar instability can significantly impact patients' quality of life and function. A large amount of research on patellar instability has been conducted in the past two decades, and a number of traditionally held principles of treatment have been challenged. This review addresses three current concepts and controversies in the treatment of patellar instability, specifically what factors lead to an increased tibial tubercle-trochlear groove distance and how to address them, when to add a tibial tubercle osteotomy to a medial patellofemoral ligament (MPFL) reconstruction, and which medial patellar stabilizers should be reconstructed. Based on current evidence, there are a few recommendations that can be made at this time. While trochleoplasty does have concerns with regard to reproducibility and complication risk, surgeons should consider this technique especially in cases with Dejour D trochlear dysplasia given high failure rates with other techniques. When evaluating whether to concomitantly perform a tibial tubercle osteotomy (TTO) with a MPFL, a TTO does appear to improve outcomes in the presence of maltracking or a positive J sign even with a tibial tuberosity-trochlear grove distance (TT-TG) of 18 to 20 mm, whereas patients without maltracking with a TT-TG of up to 25 mm may do well with an isolated MPFL reconstruction. Lastly, while MPFL reconstruction continues to have the most robust data supporting favorable outcomes, a number of biomechanical studies and short-term clinical studies have suggested promising results with medial quadriceps tendon femoral ligament and hybrid techniques.

The Expanding Use of Knee Osteotomies in the Treatment of Malalignment and Joint Preservation.

This review highlights the expanding use of knee-based osteotomies in the treatment of knee joint malalignment and joint preservation. Planning and outcomes of traditional high tibial osteotomies and distal femoral osteotomies are discussed in addition to some of the challenges encountered with these procedures. Lastly, the role of patient-specific instrumentation and three-dimensional guided templating in performing osteotomies is discussed with respect to procedures that involve biplanar corrections and those performed in combination with other joint preservation procedures.

Current and Emerging Techniques in Articular Cartilage Repair.

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

Utilization of Knee Arthroscopy for Degenerative Meniscus Tears Is on the Decline Alongside Reimbursement Rates.

In recent years, there has been a shift in healthcare away from the fee-for-service model to a value-based care model. Concomitantly, there have been changes in inflation-adjusted surgeon reimbursements for arthroscopic meniscectomies. Nationally, albeit at different rates, there has been a decrease in partial meniscectomy utilization. We feel that this is in part due to the change in healthcare economics and reimbursements as well as the growing evidence that partial meniscectomy may not be as efficacious in the treatment of degenerative meniscus tears as we once thought.

Tranexamic Acid for Rotator Cuff Repair: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

BACKGROUND: Several randomized controlled trials (RCTs) have been conducted to assess the use of tranexamic acid (TXA) in the setting of arthroscopic rotator cuff repair (ARCR). However, these studies have shown mixed results, with some showing improved intraoperative visualization, subsequent operative times, and pain levels, and others finding no difference. PURPOSE: To perform a systematic review of the RCTs in the literature to evaluate the use of TXA on ARCR. STUDY DESIGN: Meta-analysis; Level of evidence, 1. METHODS: Two independent reviewers performed the literature search based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, with a third author resolving any discrepancies. RCTs comparing TXA with a control in ARCR were included. Visualization, postoperative pain, operative time, pump pressures, and shoulder swelling were evaluated. A P value < .05 was deemed statistically significant. RESULTS: Six RCTs with 450 patients were included in this review. Overall, 5 studies evaluated intraoperative visualization, with 3 studies finding a significant difference in favor of TXA. With TXA, patients had a lower mean postoperative visual analog scale (VAS) score of 3.3, and with the control, patients had a mean VAS score of 4.1, which was statistically significant (P = .001). With TXA, the mean weighted operation time was 79.3 minutes, and with the control, the mean operation time was 88.8 minutes, which was statistically significant (P = .001). No study found any difference in intraoperative pump pressures or swelling. CONCLUSION: TXA improved visualization, operative time, and subsequent postoperative pain levels in patients undergoing ARCR.

Cannabidiol for Postoperative Pain Control After Arthroscopic Rotator Cuff Repair Demonstrates No Deficits in Patient-Reported Outcomes Versus Placebo: 1-Year Follow-up of a Randomized Controlled Trial.

Background: Cannabidiol (CBD) has been shown recently to positively affect patient pain and satisfaction immediately after arthroscopic rotator cuff repair (ARCR). However, it is unclear whether the addition of CBD to a perioperative regimen could affect postoperative outcomes. Purpose: To evaluate patient-reported outcomes among patients who underwent ARCR and received buccally absorbed CBD or an identical placebo for early postoperative pain management at 1-year follow-up. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: Eligible patients had previously participated in a multicenter, placebo-controlled, randomized, double-blinded trial that evaluated the analgesic effects of CBD in the immediate postoperative period after ARCR. The experimental group received 25 mg of CBD 3 times/day if <80 kg and 50 mg of CBD 3 times/day if >80 kg for 14 days, with the control group receiving an identical placebo. The following outcomes were assessed at minimum 1-year follow-up: visual analog scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE), and patient satisfaction. The rates of achievement of the Patient Acceptable Symptom State (PASS) were compared based on ASES at latest follow-up. Continuous and categorical variables were compared with the Mann-Whitney U test and Fisher exact test, respectively. Results: Follow-up was obtained from 83 of 99 patients (83.8%) who completed the original trial. There were no significant differences between the CBD and control groups with respect to age, sex, body mass index, rate of concomitant procedures, or number of anchors used intraoperatively. At 1-year follow-up, there were no significant differences between the CBD and control groups in VAS pain (0.8 vs 1.2, P = .38), ASES (93.0 vs 91.1, P = .71), SANE (87.6 vs 90.1, P = .24), or satisfaction (97.4 vs 95.4, P = .41). A majority of patients achieved the PASS (81.0% [CBD] vs 77.5% [control]; P = .79). Conclusion: Perioperative use of CBD for pain control among patients undergoing ARCR did not result in any significant deficits in pain, satisfaction, or patient-reported outcomes at 1-year postoperatively compared with a placebo control group. These findings suggest that CBD can be considered in a postoperative multimodal pain management regimen without detrimental effects on outcome.

Clinical and Functional Outcomes of Documented Knee Dislocation Versus Multiligamentous Knee Injury: A Comparison of KD3 Injuries at Mean 6.5 Years Follow-up.

BACKGROUND: Previous research has found that the incidence of neurovascular injury is greatest among multiligamentous knee injuries (MLKIs) with documented knee dislocation (KD). However, it is unknown whether there is a comparative difference in functional recovery based on evidence of a true dislocation. PURPOSE: To determine whether the knee dislocation-3 (KD3) injury pattern of MLKI with documented tibiofemoral dislocation represents a more severe injury than KD3 MLKI without documented dislocation, as manifested by poorer clinical outcomes at long-term follow-up. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A multicenter retrospective cohort study was performed of patients who underwent surgical treatment for KD3 MLKI between May 2012 and February 2021. Outcomes were assessed using the International Knee Documentation Committee (IKDC) score, Lysholm score, Tegner activity scale, and visual analog scale (VAS) for pain. Documented dislocation was defined as a radiographically confirmed tibiofemoral disarticulation, the equivalent radiology report from outside transfer, or emergency department documentation of a knee reduction maneuver. Subgroup analysis was performed comparing lateral (KD3-L) versus medial (KD3-M) injuries. Multivariable linear regression was conducted to determine whether documented dislocation was predictive of outcomes. RESULTS: A total of 42 patients (25 male, 17 female) were assessed at a mean 6.5-year follow-up (range, 2.1-10.7 years). Twenty patients (47.6%) were found to have a documented KD; they reported significantly lower IKDC (49.9 vs 63.0; P = .043), Lysholm (59.8 vs 74.5; P = .023), and Tegner activity level (2.9 vs 4.7; P = .027) scores than the patients without documented dislocation. VAS pain was not significantly different between groups (36.4 vs 33.5; P = .269). The incidence of neurovascular injury was greater among those with documented dislocation (45.0% vs 13.6%; P = .040). Subgroup analysis found that patients with KD3-L injuries experienced a greater deficit in Tegner activity level than patients with KD3-M injuries (Δ: -3.4 vs -1.2; P = .006) and had an increased incidence of neurovascular injury (41.7% vs 11.1%; P = .042). Documented dislocation status was predictive of poorer IKDC (ß = -2.15; P = .038) and Lysholm (ß = -2.85; P = .007) scores. CONCLUSION: Patients undergoing surgical management of KD3 injuries with true, documented KD had significantly worse clinical and functional outcomes than those with nondislocated joints at a mean 6.5-year follow-up. The current MLKI classification based solely on ligament involvement may be obscuring outcome research by not accounting for true dislocation.

The Statistical Fragility of Marrow Stimulation for Cartilage Defects of the Knee: A Systematic Review of Randomized Controlled Trials.

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

Psychological Readiness to Return to Sport (RTS) and RTS Rates Are Similar in Patients After Either Bilateral or Unilateral Anterior Cruciate Ligament Reconstruction.

Purpose: To compare psychological readiness to return to sport (RTS), RTS rate, level of return, and time to return between patients who underwent bilateral anterior cruciate ligament reconstruction (ACLR) and those who underwent unilateral ACLR. Methods: The electronic medical record at a single academic medical center was queried for patients who underwent ACLR from January 2012 to May 2020. The inclusion criteria were skeletally mature patients who underwent either single or sequential bilateral ACLR and who had undergone either the primary ACLR or second contralateral ACLR at least 2 years earlier. Bilateral ACLRs were matched 1:3 to unilateral reconstructions based on age, sex, and body mass index. Psychological readiness to RTS was assessed using the validated ACL Return to Sport After Injury (ACL-RSI) scale. This, along with time to return and level of RTS, was compared between the 2 cohorts. Results: In total, 170 patients were included, of whom 44 underwent bilateral ACLR and 132 underwent unilateral ACLR. At the time of the first surgical procedure, patients in the unilateral cohort were aged 28.8 ± 9.4 years and those in the bilateral cohort were aged 25.7 ± 9.8 years (P = .06). The average time difference between the first and second surgical procedures was 28.4 ± 22.3 months. There was no difference in psychological readiness to RTS (50.5 in bilateral cohort vs 48.1 in unilateral cohort, P = .66), RTS rate (78.0% in unilateral cohort vs 65.9% in bilateral cohort, P = .16), percentage of return to preinjury sport level (61.2% in unilateral cohort vs 69.0% in bilateral cohort, P = .21), or time to return (41.2 ± 29.3 weeks in unilateral cohort vs 35.2 ± 23.7 weeks in bilateral cohort, P = .31) between the 2 cohorts. Conclusions: Compared with patients who undergo unilateral ACLR, patients who undergo bilateral ACLR are equally as psychologically ready to RTS, showing equal rates of RTS, time to return, and level of return. Level of Evidence: Level III, retrospective cohort study.

Patients who undergo tibial tubercle anteromedialization with medial patellofemoral ligament reconstruction demonstrate similar rates of return to sport compared to isolated MPFL reconstruction.

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

Increased kinesiophobia leads to lower return to sport rate and clinical outcomes following osteochondral allograft transplantation of the knee.

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

High Rate of Patient Satisfaction with Either Telemedicine or Traditional Office-Based Follow-Up Visit After Arthroscopic Shoulder Surgery.

Background: The purpose of this study was to determine if any differences exist in patient satisfaction with office-based visits versus telemedicine visits following arthroscopic shoulder surgery. Methods: Patients undergoing shoulder arthroscopy were prospectively enrolled for 1 year. Patient demographic and clinical data (including complication events) and second postoperative visit satisfaction data were recorded and analyzed for statistical significance. Results: Ninety-six (n = 96) patients met inclusion criteria. Fifty-four patients (56.3%) participated in a traditional in-person office visit, and 42 participated in a video visit (43.8%). No significant differences were found between office and video appointments in terms of overall care satisfaction (9.46 ± 0.9 vs. 9.55 ± 1.0, p = 0.67). Females were significantly less satisfied with their second postoperative visit compared with males (8.3 ± 2.3 vs. 9.3 ± 1.5, p = 0.035). Significantly more females would also have preferred a traditional in person office visit compared with males (91% vs. 67%, p = 0.009). Video appointment patients spent significantly more time with their surgeon than office visit patients (57.64 mean rank vs. 41.39 mean rank, p = 0.003). Discussion: Video visit patients required significantly less time overall for their visit and spent significantly more time with their surgeon, although did not demonstrate differences in satisfaction.

Common treatment strategies for calcium hydroxyapatite deposition disease: a cost-effectiveness analysis.

OBJECTIVE: To determine the cost-effectiveness of rotator cuff hydroxyapatite deposition disease (HADD) treatments. METHOD: A 1-year time horizon decision analytic model was created from the US healthcare system perspective for a 52-year-old female with shoulder HADD failing conservative management. The model evaluated the incremental cost-effectiveness ratio (ICER) and net monetary benefit (NMB) of standard strategies, including conservative management, ultrasound-guided barbotage (UGB), high- and low-energy extracorporeal shock wave therapy (ECSW), and surgery. The primary effectiveness outcome was quality-adjusted life years (QALY). Costs were estimated in 2022 US dollars. The willingness-to-pay (WTP) threshold was $100,000. RESULTS: For the base case, UGB was the preferred strategy (0.9725 QALY, total cost, $2199.35, NMB, $95,048.45, and ICER, $33,992.99), with conservative management (0.9670 QALY, NMB $94,688.83) a reasonable alternative. High-energy ECSW (0.9837 QALY, NMB $94,805.72), though most effective, had an ICER of $121, 558.90, surpassing the WTP threshold. Surgery (0.9532 QALY, NMB $92,092.46) and low-energy ECSW (0.9287 QALY, NMB $87,881.20) were each dominated. Sensitivity analysis demonstrated that high-energy ECSW would become the favored strategy when its cost was < $2905.66, and conservative management was favored when the cost was < $990.34. Probabilistic sensitivity analysis supported the base case results, with UGB preferred in 43% of simulations, high-energy ECSW in 36%, conservative management in 20%, and low-energy ECSW and surgery in < 1%. CONCLUSION: UGB appears to be the most cost-effective strategy for patients with HADD, while surgery and low-energy ECSW are the least cost-effective. Conservative management may be considered a reasonable alternative treatment strategy in the appropriate clinical setting.

Patient-reported outcomes and return to pre-injury activities after surgical treatment of multi-ligamentous knee injuries in patients over 40-years-old: Average 5-years follow-up.

BACKGROUND: Multi-ligamentous knee injuries (MLKI) are potentially devastating injuries, though existing prognostic research among older patients who sustain MLKI is limited. The purpose was to investigate clinical outcomes and rates of return to pre-injury activities following surgical treatment of MLKI in patients at least 40 years old. METHODS: This study was a multi-center retrospective case series of patients who underwent surgical treatment for MLKI from 2013-2020 and were ≥ 40 years old at time of injury. Outcomes were assessed via e-mail and telephone using the International Knee Documentation Committee (IKDC) score, Lysholm score, Tegner activity scale, a satisfaction rating, and return to pre-injury sport and work surveys. Stepwise linear regression was used to assess the impact of preoperative characteristics on IKDC and Lysholm scores. RESULTS: Of 45 patients eligible for inclusion, 33 patients (mean age: 48.6 years [range: 40-72]) were assessed at a mean follow-up of 59.1 months (range 24-133). The cohort reported a mean IKDC of 63.4 ± 23.5, Lysholm of 72.6 ± 23.6, and Tegner of 3.8 ± 2.0. There was a 41.2% rate of return to sports, and 82.1% returned to work. Documented knee dislocation was predictive of poorer IKDC (ß:-20.05, p = 0.025) and Lysholm (ß:-19.99, p = 0.030). Patients aged > 50 were more satisfied compared to those 40-50 years old (96.2 ± 4.9 vs 75.6 ± 23.3, p = 0.012). CONCLUSIONS: Patients who sustained MLKI aged at least 40 at injury demonstrated fair clinical outcomes at a mean 5-year follow-up. Older patients who sustained MLKI reported a relatively high rate of return to work but were less likely to return to sports. LEVEL OF EVIDENCE: IV, Case series.

Perspectives and institutional policies on patient safety and image quality regarding the use of knee-spanning external fixators in MRI: A survey study of the Society of Skeletal Radiology.

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

Measure Twice, Cut Once: The Future of Digitally Planned Knee Osteotomies.

It is important to highlight the use of patient-specific cutting guides for knee joint osteotomies. Rationale, pitfalls, and planning of conventional osteotomy techniques are examined. The benefits of using patient-specific guides focusing on the potential for improved accuracy, efficiency, and safety are reviewed. The versatility of guides to manipulate the slope in both the coronal and sagittal planes, as well as its ability to accommodate concomitant procedures, is discussed. The time and cost differentials between standard cutting guides and three-dimensional-guided templating are also discussed.
