Current preoperative physiotherapy management strategies for patients awaiting Anterior Cruciate Ligament Reconstruction (ACLR): A worldwide survey of physiotherapy practice

Nurse-Assisted Rehabilitation Protocols Following Anterior Cruciate Ligament Reconstruction

Despite significant advancements in surgical instruments and operation skills, short- and long-term outcomes following anterior cruciate ligament reconstruction (ACLR) remain unsatisfactory, as many patients fail to return to their pre-injury level of sports. Inadequate ACL rehabilitation is the primary cause of poor outcomes. Nurses have become a crucial element in the rehabilitation process. Although there is no consensus regarding the optimal post-operative rehabilitation protocols, restoring muscle strength and neuromuscular control are consistently the primary goals. This literature review presents nurse-assisted rehabilitation protocols aiming at improving muscle strength and neuromuscular control. The review discusses postoperative rehabilitation, including home-based and supervised rehabilitation, open and closed kinetic chain exercises, eccentric and concentric training, blood flow restriction training, and plyometric training. Each training protocol has its benefits and drawbacks, and should be used cautiously in specific stages of rehabilitation. Neuromuscular training, such as neuromuscular electrical stimulation, neuromuscular control exercises, and vibration therapy, is considered crucial in rehabilitation.

Current views on preoperative rehabilitation practice after anterior cruciate ligament injury among licensed physical therapists in Saudi Arabia: An online-based cross-sectional survey

Preoperative rehabilitation is an important stage to both physically and mentally prepare patients for anterior cruciate ligament reconstruction (ACLR) and postoperative rehabilitation. This study aimed to investigate the current preoperative rehabilitation practice after anterior cruciate ligament injury among licensed physical therapists in Saudi Arabia. This was an online-based cross-sectional survey. A total of 114 physical therapists completed the survey. The survey consisted of 16 mandatory questions about management strategies, prescribed exercises, patients' physical and psychological concerns, and discussions about nonoperative management. The majority of the respondents used the following preoperative interventions: education (89.5%), closed kinetic chain exercises (66.7%), stretches (63.2%), open kinetic chain exercises (61.4%), proprioceptive exercises (59.6%), cold (56.1%), and activity modification advice (52.6%). More than half of the respondents would recommend patients awaiting ACLR to complete the exercises 2 to 4 times weekly (56.1%) for up to 8 weeks (80.7%) before ACLR. The respondents (73.7%) reported that patients awaiting ACLR did not receive preoperative rehabilitation due to 2 primary factors: the orthopedic team did not refer patients to rehabilitation specialists, and there was a lack of awareness about preoperative rehabilitation. Most therapists (86%) would discuss conservative management if a patient returned to their preinjury level of function before surgery. The surveyed physical therapists reported using various interventions and preoperative rehabilitation lengths with patients awaiting ACLR. The majority of the therapists indicated that patients awaiting ACLR did not receive preoperative rehabilitation. Future studies are needed to establish a consensus on the optimal preoperative rehabilitation program.

Preoperative predictors for return to physical activity following anterior cruciate ligament reconstruction (ACLR): a systematic review

BACKGROUND

Rates of return to physical activity after anterior cruciate ligament reconstruction surgery are sub-optimal. Optimising presurgical treatment may improve return rates. The purpose of this systematic review was to identify modifiable preoperative predictors for return to physical activity after anterior cruciate ligament reconstruction.

METHODS

Seven electronic databases (CINAHL, MEDLINE and SPORTDiscus via EBSCOhost, AMED, PsycINFO and EMBASE via OVID and Web of Science) were searched from inception to 31 March 2023. The population of focus was adults aged 18-65 who had undergone primary anterior cruciate ligament reconstruction. Studies needed to identify at least one potential modifiable preoperative predictor variable and the relationship between the predictor(s) and return to physical activity. All time-points of assessment and study designs were included. Data extraction was completed by one reviewer and verified by a second reviewer. Two reviewers completed the risk of bias assessment using the Quality in Prognostic Studies tool and Grading of Recommendations Assessment, Development and Evaluation system.

RESULTS

The search identified 2281 studies, eight met the inclusion criteria. Five studies scored 'high', and three studies scored 'moderate' risk-of-bias. All preoperative predictors were of very low-quality evidence. Five different outcome measures were used to assess return to physical activity including Tegner, Marx, Physical Activity Scale, return to play at the elite level and return to preinjury level (undefined). This was measured between 1- and 10-years post-surgery. Nine preoperative physical, six psychosocial and five demographic/clinical factors were assessed and four were found to be predictive. These included quadriceps strength, psychological profile, patient estimated ability to return and graft type (patella tendon, BPTB).

CONCLUSION

Very-low level evidence suggests that increasing quadriceps strength, managing patient expectations of their treatment outcomes, improving motivation to resume preinjury activity levels and considering the use of a BPTB graft will support return to physical activity after ACLR.

Surgeon and physiotherapist approaches to operative or non-operative management of people with recurrent patellar dislocation: A case-based UK survey

BACKGROUND

Physiotherapists are often key decision-makers on when to refer patients with recurrent patellar dislocation for surgical opinion. Limited guidance exists to aid this decision. Differences in orthopaedic surgeons' and physiotherapists' views on which patients and when to refer people for surgical consideration or non-operative care may affect outcome. This study aimed to explore orthopaedic surgeons and physiotherapists decision-making surrounding treatment opinions for patients with recurrent patellar dislocation.

METHODS

An online survey performed. UK registered and practicing orthopaedic surgeons and physiotherapists were invited to participate. The survey utilised two vignettes and a series of related questions to ascertain respondents' views on decision-making to surgical referral for people with recurrent patellar dislocation. Data were analysed using descriptive statistics and inferential statistical tests to explore factors related to responses.

RESULTS

Eighty four respondent surveys were analysed (38 surgeons, 46 physiotherapists). Overall, there was a low level of agreement amongst respondents for the management of the vignettes (k = 0.215, p = < 0.0005). Some disparity existed between the professions on the definition of recurrent patellar dislocations and the clinical features which may require an early surgical assessment. Physiotherapists were three times more likely to delay a surgical opinion for the vignettes presented in this study than the surgeons.

CONCLUSION

This is the first study to investigate orthopaedic surgeons' and physiotherapists' views on decision-making around surgical or non-operative management for recurrent patellar dislocations. High-quality research is required to underpin explicit guidance on decision-making regarding management of recurrent patellar dislocation.

Rehabilitation And Advances In Surgical Reconstruction For Anterior Cruciate Ligament Insufficiency: What Has Changed Since The 1960s? - State Of The Art

Anterior cruciate ligament (ACL) insufficiency can be disabling, given the physical and sports activity constraints that negatively impact the quality of life. Consequently, surgery is the main approach for most active patients. Nonetheless, ACL reconstruction (ACLR) cannot be successful without adequate preoperative and postoperative rehabilitation. Since the 1960s, post-ACLR rehabilitation has evolved, mainly from advances in surgery, coupled with a better understanding of the biological concepts of graft revascularization, maturation and integration, which have impacted ACL postoperative rehabilitation protocols. However, new technologies do involve a definite learning curve which could affect rehabilitation programs and produce inconsistent results. The development of rehabilitation protocols cannot be defined without an accurate diagnosis of ACL injury and considering the patient's main physical demands and expectations. This article discusses how postoperative rehabilitation following ACLR has changed from the 1960s to now, focussing on surgical technique (type of tendon graft, fixation devices, and graft tensioning), biological concepts (graft maturation and integration), rehabilitation protocols (prevention of ACL injuries, preoperative rehabilitation, postoperative rehabilitation), criteria to return to sports, patient's reported outcomes and outcome. Although rehabilitation plays an essential role in managing ACL injuries, it cannot be fully standardised preoperatively or postoperatively. Preoperative and postoperative rehabilitation should be based on an accurate clinical diagnosis, patients' understanding of their injury, graft tissue biology and biomechanics, surgical technique, the patient's physical demands and expectations, geographical differences in ACL rehabilitation and future perspectives.

Rehabilitation after ACL injury and reconstruction from the patients' perspective

OBJECTIVES

To describe and compare patients' appraisal of the rehabilitation and adherence to the rehabilitation program after acute ACL injury treated with (ACLR) or without (non-ACLR) reconstruction.

DESIGN

Prospective cohort study.

PARTICIPANTS

275 patients (143 females; mean age 25 ± 7 years) with acute ACL injury, of whom 166 patients had ACLR within 24 months.

MAIN OUTCOME

Adherence to rehabilitation was assessed using the modified Sports Injury Rehabilitation Adherence Scale (SIRAS).

RESULTS

Appraisal of rehabilitation was higher in the post-ACLR group compared to the non-ACLR group at 3 months (91% compared to 70% scored rehabilitation as necessary, p = 0.025) and at 6 months (87% compared to 70% scored it as necessary, p = 0.017). SIRAS score did not differ between 3 and 6 months for the non-ACLR group (median (IQR) 13 (2) vs 13 (2)) or the post-ACLR group (14 (1) vs 14 (2), p > 0.05). The post-ACLR group had a higher SIRAS score than the non-ACLR group at 3 and 6 months (p ≤ 0.001).

CONCLUSION

Patients treated with ACLR reported valuing their rehabilitation more and rated greater adherence to the rehabilitation programme than non-surgically treated patients. As rehabilitation is essential for good knee function, strategies to improve adherence after non-ACLR treatment should be implemented.

Current perspectives and clinical practice of physiotherapists on assessment, rehabilitation, and return to sport criteria after anterior cruciate ligament injury and reconstruction. An online survey of 538 physiotherapists

OBJECTIVES

To evaluate the perspectives and clinical practice of physiotherapists regarding rehabilitation after anterior cruciate ligament reconstruction (ACLR).

DESIGN

Online survey.

SETTING

Survey platform.

PARTICIPANTS

Greek physiotherapists.

OUTCOME MEASURES

The survey consisted of 7 sections: participant demographics, importance of ACLR rehabilitation, clinical measurements, practice, criteria to progress rehabilitation, return to running and return to sport.

RESULTS

Significant variability in measures and criteria used for clinical decision-making were found including: limb symmetry in strength and function, knee range of motion and effusion, progression, and return to sport criteria. The majority of the practitioners (28.3%) extrapolate knee strength from hop capacity. Return to running ranged from 3 to 5 months post-operatively reflecting that this was tied to physical capacities, not time from surgery. 70.0% of the Greek physiotherapists would allow return to sport ≤9 months after ACLR. Agreement was found in using: physical measures, function, and dynamic stability in ACLR rehabilitation, but the mode and interpretation varied substantially. Less than 29.0% of the physiotherapists reported using patient-reported outcome measures in their decision-making.

CONCLUSION

Current ACLR rehabilitation practices in Greece are largely not aligned with the contemporary scientific evidence and guidelines.

Early knee status affects self-reported knee function 1 year after non-surgically treated anterior cruciate ligament injury

OBJECTIVES

The primary aim was to assess impact of early knee status on self-reported knee function at 3 and 12 months and on quadriceps strength at 12 months after non-surgically treated ACL injury. The secondary aim was to describe the recovery of muscle strength during the first year after the injury.

DESIGN

Prospective cohort study.

PARTICIPANTS

70 patients (42 males; mean age 27 ± 7 years) with acute ACL injury.

MAIN OUTCOME

Knee symptoms, knee function and sporting activities were assessed with the International Knee Documentation Committee Subjective Knee Form (IKDC-SKF). Muscle strength was assessed with an isokinetic dynamometer. Clinical assessment performed at baseline was used to evaluate early knee status.

RESULTS

Global knee function, knee joint stability during ADL, gait pattern and one-legged squat assessed in mean 2 weeks after injury hadimpact on self-reported knee function at 3 and 12 months (r² 0.105-0.267). Mean limb symmetry index (LSI) of muscle strength and jump performance were 91-98% at 12 months.

CONCLUSION

Early knee symptoms affect self-reported knee function at 3 and 12 months, while other factors are important for gaining muscle strength. Muscle strength recovered during the first year after ACL injury and reached mean LSI above 90%.

LEVEL OF EVIDENCE

Prospective cohort study, level II.
