OBJECTIVES:To determine whether pain perceptions and coping strategies are predictive of the following outcomes after knee surgery in athletes: (1) return to similar level of sport, (2) improvement in symptoms, and (3) improvement in kinesiophobia. DESIGN:Prospective cohort study. METHODS:101 athletes (52 men, 49 women; mean age 32.7years) at mean 12.1months follow-up were included. Independent relationships between patient outcomes and pre-operative measures were determined: short form McGill Pain questionnaire (SF-MPQ), Pain Catastrophizing Scale (PCS), Pain Coping Measure (PCM), and the brief COPE subscales of acceptance, denial, positive reframing, and use of instrumental support. Adjustment was performed for length of follow-up, symptom duration, surgical history, age, activity level, and surgical procedure. RESULTS:Rate of return to similar level of sport was 73%; severe pain catastrophizers (PCS >36 points) had increased odds of not returning to similar level of sport (OR 11.3 CI 1.51, 236; p=0.02) whereas COPE-use of instrumental support was protective (per point increase: 0.72 CI 0.54, 0.94; p=0.02). Problem-focused coping positively correlated with improvement in IKDC-S scores (beta 0.032 SE 0.010; p=0.001). Improvement in kinesiophobia after surgery was less likely with higher pre-operative perceived pain frequency (OR 0.23 CI 0.06, 0.71; p=0.009) and higher COPE-denial scores (OR 0.43 CI 0.21, 0.88; p=0.02). CONCLUSIONS:Among athletes undergoing knee surgery, severe pain catastrophizing is negatively associated with return to similar level of sport. Instrumental support and problem-focused coping strategies are associated with improved outcomes. High preoperative pain scores are negatively associated with improvement in kinesiophobia after rehabilitation.


目的: 确定疼痛感知和应对策略是否能预测运动员膝关节手术后的以下结果 :( 1) 恢复到相似的运动水平,(2) 症状改善,(3) 运动恐惧症的改善。 设计: 前瞻性队列研究。 方法: 纳入 101 名运动员 (52 名男性,49 名女性; 平均年龄 32.7 岁),平均随访 12 个月。确定了患者预后与术前指标之间的独立关系: 简式McGill疼痛问卷 (SF-MPQ) 、疼痛灾难化量表 (PCS) 、疼痛应对措施 (PCM) 、以及接受、否认、积极重塑和使用工具支持的简短应对子量表。调整随访时间、症状持续时间、手术史、年龄、活动水平和手术操作。 结果: 恢复到相似运动水平的比率为 73%; 重度疼痛灾难恢复 (PCS >36 分) 未恢复到相似运动水平的几率增加 (OR 11.3 CI 1.51,236; p = 0.02),而使用工具支持是保护性的 (每增加点: 0.72 CI 0.54,0.94; p = 0.02)。问题焦点s ed应对po s与IKDC-S核心s的改善呈正相关 (beta 0.032 s E 0.010; p = 0.001)。术前感知疼痛频率较高 (OR 0.23 CI 0.06,0.71; p = 0.009) 和应对-否认评分较高 (OR 0.43 CI 0.21,0.88; p = 0.02)。 结论: 在接受膝关节手术的运动员中,严重疼痛灾难化与恢复到相似的运动水平呈负相关。工具性支持和以问题为中心的应对策略与改善的结果相关。术前高疼痛评分与康复后运动恐惧症的改善呈负相关。

METHODS:BACKGROUND:Postoperative cognitive dysfunction (POCD) is a common complication after orthopedic surgery, which is not conducive to the prognosis of the elderly. AIMS:We performed this study to investigate the effects of oxycodone applied for patient-controlled intravenous analgesia (PCIA) on postoperative cognitive function in elderly patients after total hip arthroplasty (THA). METHODS:Ninety-nine participants were enrolled and allocated into two groups: oxycodone group (group O) and sufentanil group (group S). The primary outcome was the incidence of POCD, diagnosed according to the changes in the Mini-mental status examination (MMSE) and Montreal Cognitive Assessment (MoCA) scores. The secondary outcomes included the plasma levels of S-100B protein and neuron-specific enolase (NSE), the amount of postoperative analgesic consumption and the incidence of adverse reactions. RESULTS:The incidence of POCD was significantly lower in patients receiving oxycodone up to the 3rd postoperative day (POD, 1st POD 27.3% vs. 51.1%, P = 0.021; 3rd POD 20.5% vs. 40.0%, P = 0.045), as compared to patients receiving sufentanil. The MMSE and MoCA scores of both groups decreased to varying degrees. However, compared with group S, the MMSE scores at 1st POD, 3rd POD, 5th POD and 7st POD in group O were higher than that in group S, while MoCA scores at 1st POD, 3rd POD and 5th POD in group O were higher. Compared with group S, the plasma levels of S-100B protein in group O at 4 h, 8 h, 12 h post-surgery were lower. While the plasma levels of NSE in group O at 4 h, 8 h, 12 h, 24 h post-surgery were lower. Number of PCIA boluses and consumption of analgesic drug during the first two POD were similar between two groups. However, postoperative incidence of nausea, vomiting and pruritus was significantly lower in patients receiving oxycodone. CONCLUSION:Oxycodone applied for PCIA in elderly patients after THA could reduce the incidence of POCD, improve postoperative cognitive function and decrease the adverse reactions.

METHODS:BACKGROUND:Primary treatment for Blount disease has changed in the last decade from osteotomies or staples to tension band plate (TBP)-guided hemiepiphysiodesis. However, implant-related issues have been frequently reported with Blount cases. The purpose of our study is to evaluate the surgical failure rates of TBP in Blount disease and characterize predictors for failure. METHODS:We performed an Institutional Review Board-approved retrospective chart-review of pediatric patients with Blount disease to evaluate the results of TBP from 2008 to 2017 and a systematic literature review. Blount cases defined as pathologic tibia-vara with HKA (hip-knee-ankle) axis and MDA (metaphyseal-diaphyseal angle) deviations ≥11 degrees were included in the analysis. Surgical failure was categorized as mechanical and functional failure. We studied both patient and implant-related characteristics and compared our results with a systematic review. RESULTS:In 61 limbs of 40 patients with mean follow-up of 38 months, we found 41% (25/61) overall surgical failure rate and 11% (7/61) mechanical failure rate corresponding to 11% to 100% (range) and 0% to 50% (range) in 8 other studies. Statistical comparison between our surgical failure and nonfailure groups showed significant differences in deformity (P=0.001), plate material (P=0.042), and obesity (P=0.044) in univariate analysis. The odds of surgical failure increased by 1.2 times with severe deformity and 5.9 times with titanium TBP in the multivariate analysis after individual risk-factor adjustment. All 7 mechanical failures involved breakage of cannulated screws on the metaphyseal side. CONCLUSIONS:Most of the studies have reported high failure rates of TBP in Blount cases. Besides patient-related risk factors like obesity and deformity, titanium TBP seems to be an independent risk factor for failure. Solid screws were protective for mechanical failure, but not for functional failure. In conclusion, efficacy of TBP still needs to be proven in Blount disease and implant design may warrant reassessment. LEVEL OF EVIDENCE:Level III-retrospective comparative study with a systematic review.

METHODS:INTRODUCTION:As cancer treatments continue to improve the overall survival rates, more patients with a history of cancer will present for anatomic total shoulder arthroplasty (TSA). Therefore, it is essential for orthopaedic surgeons to understand the differences in care required by this growing subpopulation. Although the current research suggests that good outcomes can be predicted when appropriately optimized patients with cancer undergo lower extremity total joint arthroplasty, similar studies for TSA are lacking. The primary study question was to examine whether a history of cancer was associated with an increased rate of venous thromboembolism (VTE) after TSA. Secondarily, we sought to examine any association between a history of prostate and breast cancer and surgical or medical complications after TSA. METHODS:Using a national insurance database, male patients with a history of prostate cancer and female patients with a history of breast cancer undergoing anatomic TSA for primary osteoarthritis were identified and compared with control subjects matched 3:1 based on age, sex, diabetes mellitus, and tobacco use. Patients with a history of VTE and patients who underwent reverse TSA or hemiarthroplasty were excluded. RESULTS:Female patients with a history of breast cancer and male patients with a history of prostate cancer undergoing TSA had significantly higher incidences of acute VTE (including deep venous thrombosis and pulmonary embolism) compared with matched control subjects (female patients: odds ratio, 1.41; 95% confidence interval, 1.10 to 1.81; P = 0.024 and male patients: odds ratio, 1.37; 95% confidence interval, 1.05 to 1.79; P = 0.023). No significant differences were noted in the incidences of any other complications assessed. CONCLUSION:Although a personal history of these malignancies does represent a statistically significant risk factor for acute VTE after anatomic TSA, the overall VTE rate remains modest and acceptable. The rates of other surgical and medical complications are not significantly increased in patients with a history of these cancers after TSA compared with control subjects.
