Resilience correlates with patient-reported outcome measures at a minimum of 2 years after arthroscopic rotator cuff repair.

Aims: We aimed to evaluate the correlation between preoperative and postoperative resilience scores and postoperative outcomes at minimum 2-year follow-up after arthroscopic rotator cuff repair. Methods: We prospectively enrolled 98 patients who underwent rotator cuff repair. We assessed resilience using the Brief Resilience Scale. Postoperatively, we obtained patient-reported outcomes measures including American Society of Shoulder and Elbow Surgeons scores, Single Assessment Numeric Evaluation, and Patient-Reported Outcome Measurement Information System Global Health-10 at minimum 2-year follow-up. We used Spearman correlation coefficients (r) to assess the relationship between variables. Results: Ninety-one of 98 patients (93%) provided follow-up at an average of 32 months. Preoperative Brief Resilience Scale did not show a statistically significant correlation with American Society of Shoulder and Elbow Surgeons (r = 0.156; p = 0.142). However, preoperative Brief Resilience Scale showed statistically significant correlations with Patient-Reported Outcome Measurement Information System Global Health-10 (r = 0.290; p = 0.005) and Single Assessment Numeric Evaluation (r = 0.259; p = 0.014). Postoperative Brief Resilience Scale showed statistically significant correlations with American Society of Shoulder and Elbow Surgeons (r = 0.291; p = 0.005), Single Assessment Numeric Evaluation (r = 0.384; p < 0.001) and Patient-Reported Outcome Measurement Information System Global Health-10 (r = 0.515; p < 0.001). Discussion: Resilience may be a valuable predictor of patients at risk of having suboptimal outcomes after rotator cuff repair and a target to improve surgical outcomes through non-surgical means.

Impact of patient resilience on early recovery from rotator cuff repair.

Aims: We sought to evaluate early recovery from rotator cuff repair by assessing the correlation between patient resilience and postoperative shoulder pain and function, and physical and mental health. Methods: Patients scheduled to undergo arthroscopic rotator cuff repair were prospectively enrolled. Resilience was assessed using the Brief Resilience Scale (BRS), pain and function was measured by American Society of Shoulder and Elbow Surgeons (ASES) shoulder scores, and physical and mental health was measured by the Patient-Reported Outcome Measurement Information System Global Health-10 (PROMIS-10). All scores were obtained preoperatively and postoperatively at three- and six months. Spearman correlation coefficient (r) was used to assess the relationship between variables. Results: Ninety-eight patients ultimately underwent rotator cuff repair; 76 and 68 patients provided three- and six-month follow-up, respectively. There was no statistically significant correlation between preoperative BRS and three- and six-month ASES. However, there was a statistically significant correlation between preoperative BRS and three-month PROMIS-10 (r = 0.3763, p = 0.009) and concurrent BRS and PROMIS-10 at three months (r = 0.5657, p = 0.0025) and six months (r = 0.5308, p = 0.0025). Discussion: Resilience appears to be more predictive of global physical and mental health than shoulder pain and function in early recovery from rotator cuff repair.

Intraoperative navigation and preoperative templating software are associated with increased glenoid baseplate screw length and use of augmented baseplates in reverse total shoulder arthroplasty.

BACKGROUND: Preoperative templating software and intraoperative navigation have the potential to impact baseplate augmentation utilization and increase screw length for baseplate fixation in reverse total shoulder arthroplasty (rTSA). We aimed to assess their impact on the (1) baseplate screw length, (2) number of screws used, and (3) frequency of augmented baseplate use in navigated rTSA. METHODS: We compared 51 patients who underwent navigated rTSA with 63 controls who underwent conventional rTSA at a single institution. Primary outcomes included the screw length, composite screw length, number of screws used, percentage of patients in whom 2 screws in total were used, and use of augmented baseplates. RESULTS: Navigation resulted in the use of significantly longer individual screws (36.7 mm vs. 30 mm, P < .0001), greater composite screw length (84 mm vs. 76 mm, P = .048), and fewer screws (2.5 ± 0.7 vs. 2.8 ± 1, P = .047), as well as an increased frequency of using 2 screws in total (35 of 51 patients [68.6%] vs. 32 of 63 controls [50.8%], P = .047). Preoperative templating resulted in more frequent augmented baseplate utilization (76.5% vs. 19.1%, P < .0001). CONCLUSION: The difference in the screw length, number of screws used, and augmented baseplate use demonstrates the evolving role that computer navigation and preoperative templating play in surgical planning and the intraoperative technique for rTSA.

The Shoulder Telehealth Assessment Tool in Transition to Distance Orthopedics.

The role of telehealth in orthopedic surgery is rapidly expanding, a movement largely brought about by the coronavirus disease 2019 (COVID-19) pandemic. Virtual clinic encounters using a video chat platform or a simple telephone call offer the patient and surgeon numerous advantages that are now better appreciated by the orthopedic community at large. However, barriers to effective patient evaluation exist, and a successful patient assessment is highly dependent on technique. In particular, performing a shoulder physical examination during a virtual encounter poses many obstacles. We present a technique to complete a patient-led, comprehensive shoulder physical examination using an easy-to-understand pictorial guide called the Shoulder Telehealth Assessment Tool (STAT). A STAT form is provided to the patient and designed to be completed at home without the real-time instruction of a provider, before the virtual encounter. Parameters include assessments of all planes of shoulder range of motion, visual analog scale (VAS) and Single Assessment Numeric Evaluation (SANE) scores, and the components necessary to allow for conversion to an abbreviated Constant shoulder score if the provider so desires.

Editorial Commentary: Is It Time to Make a Change? Don't Throw Out the Old Rigid Anterior Cruciate Ligament Femoral Reamers Just Yet.

Debate remains on which technique(s) of femoral tunnel drilling is most able to recreate an anatomic femoral footprint in anterior cruciate ligament reconstruction. The most commonly used techniques are the transtibial, anteromedial rigid reamer (AM-RR), anteromedial flexible reamer (AM-FR), and outside-in. Technique is based solely on surgeon preference. Each technique carries its own risks, benefits, advantages, and disadvantages, and there remains no single "gold standard." The AM-RR, AM-FR, and outside-in methods are considered independent or "unconstrained" methods that allow more variability in recreating anatomic angles compared with the transtibial technique, which is "constrained" by the tibial tunnel. Historically, the AM-RR and AM-FR techniques have not been subdivided in the orthopaedic literature. Further study is needed to determine whether there is a significant difference between the 2 techniques with respect to anatomical, biomechanical, and clinical results.

The Quad Link Technique for an All-Soft-Tissue Quadriceps Graft in Minimally Invasive, All-Inside Anterior Cruciate Ligament Reconstruction.

The quadriceps tendon autograft has become an attractive option for anterior cruciate ligament reconstruction (ACLR) because of its robust size and versatility as a graft. Emerging literature has shown impressive biomechanical viability and promising clinical outcomes. The substantial size of a quadriceps graft and the shorter graft requirement of the all-inside approach obviate the need to harvest a bone plug for supplemental graft length and allow the use of an all-soft-tissue graft. The recent development of sophisticated harvest tools has mitigated prior issues reported with quadriceps tendon harvest. Quadriceps graft harvest is now less technically challenging, more reproducible, and can be done through a minimally invasive incision. However, an optimal technique for attachment of the adjustable loop suspensory fixation devices to an all-soft-tissue quadriceps tendon graft has yet to be established. We describe our method for quadriceps tendon harvest and present the Quad Link technique for attachment of adjustable loop suspensory fixation devices to a quadriceps graft for ACLR.

Advantages and Disadvantages of Transtibial, Anteromedial Portal, and Outside-In Femoral Tunnel Drilling in Single-Bundle Anterior Cruciate Ligament Reconstruction: A Systematic Review.

PURPOSE: Controversy exists regarding the best method for creating the knee anterior cruciate ligament (ACL) femoral tunnel or socket. The purpose of this study was to systematically review the risks, benefits, advantages, and disadvantages of the endoscopic transtibial (TT) technique, anteromedial portal technique, outside-in technique, and outside-in retrograde drilling technique for creating the ACL femoral tunnel. METHODS: A PubMed search of English-language studies published between January 1, 2000, and February 17, 2014, was performed using the following keywords: "anterior cruciate ligament" AND "femoral tunnel." Included were studies reporting risks, benefits, advantages, and/or disadvantages of any ACL femoral technique. In addition, references of included articles were reviewed to identify potential studies missed in the original search. RESULTS: A total of 27 articles were identified through the search. TT technique advantages include familiarity and proven long-term outcomes; disadvantages include the risk of nonanatomic placement because of constrained (TT) drilling. Anteromedial portal technique advantages include unconstrained anatomic placement; disadvantages include technical challenges, short tunnels or sockets, and posterior-wall blowout. Outside-in technique advantages include unconstrained anatomic placement; disadvantages include the need for 2 incisions. Retrograde drilling technique advantages include unconstrained anatomic placement, as well as all-epiphyseal drilling in skeletally immature patients; disadvantages include the need for fluoroscopy for all-epiphyseal drilling. CONCLUSIONS: There is no one, single, established "gold-standard" technique for creation of the ACL femoral socket. Four accepted techniques show diverse and subjective advantages, disadvantages, risks, and benefits. LEVEL OF EVIDENCE: Level V, systematic review of Level II through V evidence.

Disadvantages and advantages of transtibial technique for creating the anterior cruciate ligament femoral socket.

Anterior cruciate ligament (ACL) femoral socket techniques have distinct advantages and disadvantages when considering the following techniques: transtibial, anteromedial portal, outside-in, and outside-in retroconstruction. There is no one perfect technique and we have an incomplete understanding of anatomical, biomechanical, isometry, stability, and clinical outcomes. Our primary focus is transtibial technique for creating the ACL femoral socket. Advantages include less invasive, isometric graft placement, stable Lachman exam, and minimal graft impingement with the tunnel and notch. Disadvantages include nonanatomic vertical graft placement that can cause rotational instability and positive pivot shift, interference screw divergence, graft-tunnel length mismatch, femoral socket constraint, posterior cruciate ligament impingement, and a short, oblique tibial tunnel that may undermine the medial plateau in an attempt to achieve anatomic ACL reconstruction.

Plateau-patella angle in evaluation of patellar height after total knee arthroplasty.

The plateau-patella angle (PPA) has been proposed as a new and simpler method to describe patellar height. This method has not been used or validated in knees following total knee arthroplasty (TKA). A modified PPA (mPPA) was developed for use in this population. The method was validated by determining the interobserver and intraobserver reliability of the technique in 50 consecutive patients compared to three well-described methods of describing patellar height after TKA. Three observers then evaluated the mPPA of 297 post-operative radiographs to describe a normal range after TKA for a given technique and implant. The interobserver reliability was the highest for the mPPA compared to the other methods. The mean mPPA for the entire cohort was 21.06, 20.49, and 19.94 for the three observers. The modified plateau-patella angle is a reliable way to evaluate patellar height in patients who have undergone total knee arthroplasty.

Relationship of bone mineral density of spine and femoral neck to distal radius fracture stability in patients over 65.

PURPOSE: We hypothesized that an increasing degree of osteopenia in the femoral neck and lumbar spine would be associated with loss of reduction after closed manipulation and splinting of distal radius fractures in patients over 65 years of age. METHODS: We performed a retrospective review, evaluating 78 patients with displaced distal radius fractures managed with closed reduction and splinting. T-scores from the lumbar spine and femoral neck were recorded from dual-energy x-ray absorptiometry scans performed either within 1 year before or after injury. Volar tilt, radial height, radial inclination, and ulnar variance were evaluated from the initial fracture, postreduction, and final follow-up radiographs. We calculated the percentage of reduction maintained regarding reduction variable. We correlated T-scores of the lumbar spine and femoral neck with the percentage of retained reduction. RESULTS: We found no correlation between T-scores of the lumbar spine or femoral neck and the amount of reduction lost throughout the healing process of distal radius fractures with respect to volar tilt, radial height, radial inclination, or ulnar variance. Reduction was of no anatomical benefit in 53% to radial height, 44% to radial inclination, and 54% to ulnar variance. CONCLUSIONS: There appears to be no relationship between bone mineral density, based on T-scores of the lumbar spine and femoral neck, and the ability to maintain reduction after closed manipulation and splinting of displaced distal radius fractures in patients over 65 years of age. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic III.

Marrow stimulation improves meniscal healing at early endpoints in a rabbit meniscal injury model.

PURPOSE: To critically evaluate the effect of marrow stimulation (MS) on the extent of healing and the local biological environment after meniscal injury in ligamentously stable knees in a rabbit model. METHODS: A reproducible 1.5-mm cylindrical defect was created in the avascular portion of the anterior horn of the medial meniscus bilaterally in 18 New Zealand White rabbits (36 knees). In right knees (MS knees), a 2.4-mm Steinman pin was drilled into the apex of the femoral intercondylar notch and marrow contents were observed spilling into the joint. Left knees served as controls. Rabbits were killed in 3 groups (n = 6 rabbits each) at 1, 4, and 12 weeks with meniscal harvest and blinded histomorphometric and histologic evaluation using an established 3-component tissue quality score (range, 0 to 6). One-week specimens were also evaluated for the presence of proregenerative cytokines using immunohistochemistry. RESULTS: The mean proportion of the avascular zone defect bridged by reparative tissue was greater in MS knees than in controls at each endpoint (1 week, 55% v 30%, P = .02; 4 weeks, 71% v 53%, P = .047; 12 weeks, 96% v 77%, P = .16). Similarly, there was a consistent trend toward superior tissue quality scores in knees treated with MS compared with controls (1 week, 1.8 v 0.3, P = .03; 4 weeks, 4.3 v 2.8, P = .08; 12 weeks, 5.9 v 4.5, P = .21). No statistically significant differences, however, were observed at the 12-week endpoint. Increased staining for insulin-like growth factor I, transforming growth factor-ß, and platelet-derived growth factor was observed in regenerated tissue, compared with native meniscal tissue, in all specimens at 1 week. Staining density for all growth factors was similar, however, in reparative tissue of MS and control knees. CONCLUSIONS: The results of this study suggest that marrow stimulation leads to modest improvements in quality and quantity of reparative tissue bridging a meniscal defect, particularly during the early recovery period. CLINICAL RELEVANCE: Clinical evaluation of marrow stimulation techniques designed to enhance healing in isolated meniscus repair surgery may be indicated.

Cytokine-mediated inflammatory reaction following posterior cervical decompression and fusion associated with recombinant human bone morphogenetic protein-2: a case study.

STUDY DESIGN: Case study with unique laboratory analysis. OBJECTIVE: To present a potentially serious adverse event that may occur in unique individuals when using recombinant human bone morphogenetic protein-2 (rhBMP-2) to augment fusion in posterior cervical spine surgery. SUMMARY OF BACKGROUND DATA: The use of rhBMP-2 to augment posterior cervical decompression and fusion has not been approved by the Food and Drug Administration but has been advocated as safe to use by case series studies and multiple authors. METHODS: A 66-year-old patient with myelopathy underwent posterior cervical decompression and fusion, using rhBMP-2 as a bone graft substitute. The patient had complete resolution of symptoms after surgery until day 6, when she experienced increasing pain and weakness. T2 magnetic resonance images revealed a high intensity fluid collection compressing the cervical cord posteriorly. Emergent decompression was performed and the patient improved until postoperative day 12 when the same clinical scenario occurred. Symptoms again improved with surgical debridement. The clear, nonsanguineous fluid was sent for a quantitative cytokine panel each time. The case is reviewed with specific reference to the evolving literature regarding rhBMP-2 use in the spine, and the findings of seroma analysis. RESULTS: The fluid analysis of the seroma fluid at the time of both debridements showed impressive elevations in inflammatory cytokines, especially IL-6 and IL-8. CONCLUSION: Acute inflammatory reactions to rhBMP-2 can occur in the posterior cervical spine and can lead to significant morbidity. Host factors, BMP-2 dosage, and carrier factors all likely play a role in these complex reactions and must be considered every time an "off label" usage of rhBMP-2 is considered. More study is clearly indicated.
