股四头肌肌腱自体移植 ACL 术后康复的 BFR 疗法
股四头肌肌腱自体移植前交叉韧带重建术后康复的血流限制疗法:一项随机对照试验
研究概览
详细说明
拟议研究的总体目标是进行一项前瞻性随机对照试验,以调查在标准术后康复方案中加入 BFR 疗法是否能显着改善 ACLR 在手术技术和移植物选择方面标准化后的临床结果。 研究者的中心假设是,加入 BFR 疗法有可能加速手术恢复,加快重返工作岗位,并最大限度地提高 ACLR 后的医疗准备。 在提议的经过验证的试验中,患者报告的结果测量将用于评估功能性临床改善,而在 MRI 上测量的股四头肌横截面积 (CSA) 将用于量化治疗对股四头肌力量的影响。 使用这种模式的基本原理是基于这样一个事实,即股四头肌 CSA 和肌肉体积的测量作为整体股四头肌功能的替代指标得到了很好的描述,并且许多研究令人信服地证明了这些参数与股四头肌力量之间的正相关 4, 17。 然而,尽管有这些报告,承认 MRI 作为股四头肌力量的替代指标的接受度仍然有限。 因此,将在术后约 6 个月和 9 个月测量手术和非手术膝伸肌(股四头肌)的等速和等长股四头肌力量。 双侧大腿的 MRI 将在 ACLR 之前立即进行,以在手术和非手术下肢中建立基线 CSA。 然后,在随机分配到标准康复方案 (REHAB) 或 BFR 康复方案 (REHAB + BFR) 的患者中,在标准化的 16 周术后康复方案结束后,将立即进行重复 MRI。最后,MRI 将一旦患者恢复到不受限制的身体活动,在术后 52 周重复检查 CSA 的潜在变化。
目的 1:确定在标准术后康复方案中加入 BFR 疗法是否会增加 ACLR 后股四头肌的横截面积和体积,如磁共振成像 (MRI) 所测量。
假设:与术后 16 周测量的标准术后康复方案相比,在 ACLR 后标准术后康复方案中加入 BFR 疗法会增加股四头肌的 CSA 和体积。
目的 2:通过在术后 52 周进行重复 MRI,确定观察到的股四头肌 CSA 和体积的任何增加是否持续超过术后 16 周 BFR 治疗的停止
假设:观察到的股四头肌 CSA 和体积的增加将持续到术后 52 周 BFR 治疗停止后。
目的 3:确定通过 MRI 获得的 CSA 测量值是否能可靠地预测膝伸肌力量。
假设:通过 MRI 获得的 CSA 测量值可靠地预测了通过等速和等长测试测量的膝伸肌力量。
目标 4:确定在 ACLR 后标准术后康复方案中加入 BFR 疗法与标准术后康复方案相比是否会在术后 24、36 和 52 周使用患者显着改善功能结果报告结果 (PRO)。
假设:与术后 24、36 和 52 周的标准术后康复方案相比,ACLR 后标准术后康复方案中加入 BFR 疗法将显着改善 PRO。

Patient Reported Outcome - Pain on 10 cm Visual Analog Scale (VAS)
大体时间:[Time Frame: pre-operatively] [Time Frame: 7 months post-operatively] [Time Frame: 10 months post-operatively] [Time Frame: 13 months post-operatively]
|
The VAS is a unidimensional measure of pain intensity that has been frequently reported among adults.
The simplest VAS is represented as a horizontal 10 cm line.
The ends are defined as the extreme limits of parameter being measured (e.g.
pain) oriented from the left (worst) to the right (best.)
Patients are asked mark their perceived level of pain on the horizontal line.
The VAS score is determined by measuring in mm from the left hand end of the horizontal line to where the patient marks.
A higher score represents greater pain intensity.

Patient Reported Outcome - Lysholms Score
大体时间:[Time Frame: pre-operatively] [Time Frame: 7 months post-operatively] [Time Frame: 10 months post-operatively] [Time Frame: 13 months post-operatively]
|
Comprised of 8 items (limp, support, locking, instability, pain, swelling, stair climbing, squatting), which patients are asked a series of questions to characterize their experiences with respect to each of these 8 items.
Patients' responses are summed, with a score of 100 denoting no symptoms or debility.

Patient Reported Outcome - International Knee Documentation Committee Form (IKDC)
大体时间:[Time Frame: pre-operatively] [Time Frame: 7 months post-operatively] [Time Frame: 10 months post-operatively] [Time Frame: 13 months post-operatively]
|
This questionnaire is broken down into three categories: symptoms, sports activity, and knee function.
The symptoms subscale focuses on an assessment of pain, stiffness, swelling, and the sensation of "giving-way" of the knee.
The sports activity subscale focuses on completion of tasks such as going up and down stairs, rising from a seated position, squatting, and jumping.
The knee function subscale asks the respondent to characterize their knee at present versus prior to injury.
The IKDC is scored out of 100 points, with a score of 100 representing optimal knee function.

Patient Reported Outcome - Knee Osteoarthritis Outcome Score (KOOS)
大体时间:[Time Frame: pre-operatively] [Time Frame: 7 months post-operatively] [Time Frame: 10 months post-operatively] [Time Frame: 13 months post-operatively]
|
The KOOS is a comprehensive scoring system that evaluates both short and long-term consequence of knee injury.
It is comprised of 42 items, which are scored separately in 5 subscales (pain (9 items), other symptoms (7 items), function in daily living (17 items), function in sport and recreation (5 items), and knee-related quality of life (5 items).)
Among the strengths of the KOOS as a PRO is its inclusion of two different subscales for physical function relating to daily life, sport, and recreation.
A score of 100 represents no knee symptoms, which is then converted to a percentage score to characterize a patient's overall satisfaction with their knee function.

|
The CD- RISC 2, 10, or 25 item validated instrument that is self-rated assessment of psychological resiliency.
This instrument has shown reliability in measuring the ability to adapt to change, the ability to deal with what comes along, the ability to cope with stress, the ability to stay focused and think clearly, the ability to not get discouraged in the face of failure, the ability to handle unpleasant feelings such as anger, pain or sadness.

Anterior Cruciate Ligament Return to Sport after Injury (ACL-RSI) (Short version 6Q)
大体时间:[Time Frame: pre-operatively] [Time Frame: 7 months post-operatively] [Time Frame: 10 months post-operatively] [Time Frame: 13 months post-operatively]
|
ACL-RSI instrument measure one's emotion, confidence, and risk appraisal when returning to sports after an ACL injury and/or reconstructive surgery.
The survey consists of 12 items that are graded on a visual analogue scale from 0 points (extremely negative psychological responses) to 100 points (no negative psychological responses).
The results of the survey have been found to be strongly and significantly associated with return to sport.
