Tracking patient outcomes after anterior cruciate ligament reconstruction

Management of Meniscus Pathology with Concomitant Anterior Cruciate Ligament Injury

PURPOSE OF REVIEW

The purpose of this review is to summarize current clinical knowledge on the prevalence and types of meniscus pathology seen with concomitant anterior cruciate ligament (ACL) injury, as well as surgical techniques, clinical outcomes, and rehabilitation following operative management of these pathologies.

RECENT FINDINGS

Meniscus pathology with concomitant ACL injury is relatively common, with reports of meniscus pathology identified in 21-64% of operative ACL injuries. These concomitant injuries have been associated with increased age and body mass index. Lateral meniscus pathology is more common in acute ACL injury, while medial meniscus pathology is more typical in chronic ACL deficiency. Meniscus tear patterns associated with concomitant ACL injury include meniscus root tears, lateral meniscus oblique radial tears of the posterior horn (14%), and ramp lesions of the medial meniscus (8-24%). These meniscal pathologies with concomitant ACL injury are associated with increased rotational laxity and meniscal extrusion. There is a paucity of comparative studies to determine the optimal meniscus repair technique, as well as rehabilitation protocol, depending on specific tear pattern, location, and ACL reconstruction technique. There has been a substantial increase in recent publications demonstrating the importance of meniscus repair at the time of ACL repair or reconstruction to restore knee biomechanics and reduce the risk of progressive osteoarthritic degeneration. Through these studies, there has been a growing understanding of the meniscus tear patterns commonly identified or nearly missed during ACL reconstruction. Surgical management of meniscal pathology with concomitant ACL injury implements the same principles as utilized in the setting of isolated meniscus repair alone: anatomic reduction, biologic preparation and augmentation, and circumferential compression. Advances in repair techniques have demonstrated promising clinical outcomes, and the ability to restore and preserve the meniscus in pathologies previously deemed irreparable. Further research to determine the optimal surgical technique for specific tear patterns, as well as rehabilitation protocols for meniscus pathology with concomitant ACL injury, is warranted.

Does Concomitant Meniscectomy or Meniscus Repair Affect Muscle Strength, Lower Extremity Balance, and Functional Tests after Anterior Cruciate Ligament Reconstruction?

Background/Objective: The effects of concomitant meniscal tears and their associated treatment on strength, lower extremity balance, and functional status after anterior cruciate ligament reconstruction (ACLR) have not been widely investigated. This study aimed to compare the functional outcomes in patients who underwent ACLR with concomitant treatment of the medial meniscus repair versus meniscectomy when returning to unrestricted physical activity. Methods: A total of 85 patients who underwent primary ACLR with combined meniscal repair (MREP; n = 39) or meniscectomy (MRES; n = 46) were assessed. The dataset included the Functional Movement ScreenTM (FMS) outcomes and single-leg balance test (SLBT) with anterior-posterior, medial-lateral, and overall stability indexes. Isokinetic knee extension and flexion strengths were tested at velocities of 60 deg·s-1 and 180 deg·s-1. The peak torque-to-body weight ratio (PT/BW) and limb symmetry index (LSI) were calculated. Results: In the functional assessment, there was no significant inter-group difference in the composite score of the FMS (MREP: 15.08 pts vs. MRES: 15.13 pts; p > 0.05). The SLBT outcomes in inter-group and inter-extremity comparisons were irrelevant (p > 0.05), too. Significant differences emerged in the inter-group comparison of the knee extension strength in the non-operated extremity at both 60 deg·s-1 and 180 deg·s-1 (p = 0.02). Inter-extremity differences were significant in both the MREP and MRES groups for knee extension and flexion at both angular velocities (all p values < 0.05). For knee extension, the LSI values ranged from 82% to 87%, and for flexion, from 77% to 84%, with no significant inter-group differences. Conclusions: Patients undergoing ACLR with concomitant meniscal repair or resection did not exhibit differences in isokinetic muscle strength, lower extremity balance, and functional tests upon returning to activity. However, participants in both groups demonstrated significant differences between the operated and non-operated extremities as far as the knee joint extensor and flexor strengths are concerned. Therefore, rehabilitation protocols should prioritize equalizing inter-extremity strength differences after the ACLR with additional treatment procedures addressing the menisci.

Patient-reported outcomes following free flap lower extremity reconstruction: A systematic review and meta-analysis

PURPOSE

Free flap reconstruction in the lower extremity has shown success for the management of large and complex defects, restoration of function, and favorable aesthetic outcomes. Patient-reported outcomes (PROs) have not been well explored in previous literature. This meta-analysis aimed to provide a comprehensive summary of PROs after free flap reconstruction in the lower extremity.

METHODS

We searched MEDLINE and Embase from 1946 to 2021 for studies reporting on PROs following free flap reconstruction in the lower extremity.

RESULTS

Overall, 53 studies were included, and 11 studies reported validated PRO measures for meta-analysis. A total of 1953 patients underwent reconstruction with 1958 free flaps for lower limb defects with a mean follow-up of 3.26 (0.25-7.83) months. The mean postoperative Lower Extremity Functional Scale (LEFS) scores were 60.3 (±12) out of 80 points (4 studies, 85 patients). The mean postoperative AOFAS scores were 75.1 (±15) out of 100 points (4 studies, 68 patients). The mean postoperative SF-36 scores were 88.1 (±8.0) out of 100 points; mental health component was 48.7 (±8.9), and physical component was 38.4 (±8.2), out of 50 points (4 studies, 88 patients).

CONCLUSION

Our findings demonstrated that patients report improved physical health, mental health, and function following lower extremity reconstruction with free flaps. Patients reported similar improvements in functional scores following lower extremity reconstruction regardless of their free flap type. Furthermore, patients with myocutaneous flaps may have improved mental health and worse physical health scores when compared to perforator flaps. The evidence profiles presented in this review indicate that additional research is needed to help guide future decision-making.

Effects of kinesio tape on kinesiophobia, balance and functional performance of athletes with post anterior cruciate ligament reconstruction: a pilot clinical trial

Background

Anterior cruciate ligament trauma is one of the most common knee injuries in professional athletes. This study aimed to investigate the effects of kinesio taping on kinesiophobia, balance, and functional performance in athletes after anterior cruciate ligament reconstruction.

Methods

This randomized, placebo-controlled clinical trial was performed on 20 athletes with anterior cruciate ligament reconstruction (mean age 32.3 ± 6.2 years) at the time of return to sport. The subjects were randomly assigned to the kinesio tape (KT) group (n = 10) or placebo KT group (n = 10).

While subjects under taped, the following outcomes were measured at baseline, 10 minutes after the intervention, and 2 days later. Kinesiophobia, balance, strength, and functional / agility performance were assessed by the Tampa Scale, Y balance test (YBT), single-leg hops, and 10-yard extremity functional test, respectively.

Results

The results did not show a significant difference between-group post-intervention differences in kinesiophobia (Mean between-group difference = − 6.30, 95% CI = − 4.35 to 1.42, P-value = 0.17). Likewise, no significant statistical difference was observed between two study groups in terms of YBT scores (Mean between-group difference ranged over = − 6.30, 95% CI = − 1.1 to 4.7, the effect sizes ranged over = 0.01 to 0.31), P-value > 0.05), Single Leg Hop (Mean between-group difference = − 0.48, 95% CI for difference ranged over = − 10.3 to 9.3, effect size = 0.001, P-value = 0.918), and 10 Yard test scores (Mean between-group difference = − 0.30, 95% CI = (− 1.3 to 0.75), effect size = 0.02, P-value = 0.55) at 2 days after the KT. In the KT and placebo KT groups, RMANOVA indicated that the differences in all variables scores were significant over time with large effect sizes (effect size ranged over = 0.94–0.99; all P-value < 0.001).

Conclusion

This study gives no support for any beneficial effect of kinesio taping on the reduction of kinesiophobi or improvement of balance score and functional performance in athletes with post anterior cruciate ligament reconstruction.

Does an Accelerated Program Give Equivalent Results in Both Elite Athletes and Nonathletes?

CONTEXT

Although many researchers have investigated the functional outcomes of different accelerated rehabilitation programs after anterior cruciate ligament reconstruction (ACLR), the functional results of the same accelerated rehabilitation program following ACLR applied for both elite athletes and nonathletes have not yet been investigated.

OBJECTIVE

To examine the effects of the same accelerated anterior cruciate ligament rehabilitation program on pain and functionality of elite athletes and nonathletes.

DESIGN

Prospective preintervention-postintervention design.

SETTING

Physiotherapy department.

PARTICIPANTS

Fifteen elite athletes and 15 nonathletes who underwent unilateral ACLR with autologous hamstring tendon graft.

INTERVENTION

All participants received the same protocol for 6 weeks (5 sessions in a week).

MAIN OUTCOME MEASURES

Primary measurements were pain intensity, which was measured by visual analog scale, range of motion measurement using universal goniometer, and functionality, which was detected by Lysholm score. Secondary measurements were short form-36 and Beck Depression Inventory.

RESULTS

Higher Lysholm (P = .001) and Beck Depression Inventory (P = .03) scores were observed in the elite athlete group, and higher pain (P = .001) was observed in the nonathlete group at baseline assessments. Significant improvement detected for pain (P < .05), knee flexion range (P < .05), Lysholm score (P < .05), and Beck Depression Inventory (P < .05) compared with preintervention for both groups. Finally, after comparing the mean change values, the nonathlete group displayed greater decrease in pain level (P = .01) and participants in the elite athlete group further showed a greater decrease in depression level (P = .001).

CONCLUSIONS

This study found that the same accelerated rehabilitation protocol provides significant improvements for pain, functionality, and depression in both elite athletes and nonathletes after ACLR. Clinicians should consider our results when applying an anterior cruciate ligament rehabilitation program for nonathlete groups.

Evolution of Functional Recovery using Hop Test Assessment after ACL Reconstruction

The purpose of this study was to evaluate improvements in functional performance through the use of the Limb Symmetry Index of Single and Triple Hop tests between 12 and 52 weeks after anterior cruciate ligament reconstruction, and to compare these values with usual time-based and performance-based criteria used during the return to sport continuum. Repeated functional assessments using Single and Triple Hop Tests at 12, 16, 22, 26, 39 and 52 postoperative weeks were evaluated. At each session, the median and interquartile range of Limb Symmetry Index of tests were calculated and compared with the usual criteria: return to participation:≥85%, between 12-16 w; return to play:≥90%, between 26-39 w. The results indicate that the median increased over time to 39 postoperative weeks and then stabilized. For Single Hop Test, wide variability was seen at 12 and 16 weeks (interquartile range=20%); this was lower from 22 to 52 weeks (interquartile range=8-6%). At 12 weeks for Single Hop Test, the median was 83.6% and did not meet>85% criteria for return to participation. Hop tests could be interesting functional tests to follow the functional recovery and help decision-making regarding return to participation and return to play.

Anterior cruciate ligament reconstruction with concomitant meniscal surgery: a systematic review and meta-analysis of outcomes

PURPOSE

The aim of this review was to compare the clinical outcomes of anterior cruciate ligament reconstruction (ACLR) with either meniscal repair or meniscectomy for concomitant meniscal injury. The primary hypothesis was that short-term clinical outcomes (≤ 2-year follow-up) for ACLR concomitant with either meniscal repair or resection would be similar. The secondary hypothesis was that ACLR with meniscal repair would result in better longer term outcomes compared with meniscal resection.

METHODS

The authors searched two online databases (EMBASE and MEDLINE) from inception until March 2018 for the literature on ACLR and concurrent meniscal surgery. Two reviewers systematically screened studies in duplicate, independently, and based on a priori criteria. Quality assessment was also performed in duplicate. The Knee injury and Osteoarthritis Outcome Score (KOOS) sub-scale scores at 2 years post-operatively were combined in a meta-analysis of proportions using a random-effects model.

RESULTS

Of 2566 initial studies, 25 studies satisfied full-text inclusion criteria. Mean follow-up was 2.09 years, with a total sample of 37,087 subjects including controls. The meta-analysis demonstrated equivocal results at 2 years, except for KOOS symptom scores which favoured meniscal resection over repair. Mean KT-1000 side-to-side difference (SSD) scores were 1.51 ± 0.60 mm for meniscal repair, 1.96 ± 0.36 mm for meniscal resection, and 1.58 ± 0.20 for control patients (isolated ACLR). Medial meniscal repair showed decreased anterior knee joint laxity compared to medial meniscal resection (P < 0.001). Patients with meniscal repair had higher rates of re-operation (13.3% vs 0.8% for meniscal resection, P < 0.001).

CONCLUSION

Patients with ACLR combined with meniscal resection demonstrate better symptoms at 2-year follow-up compared to patients with ACLR combined with meniscal repair. ACLR combined with meniscal repair results in decreased anterior knee joint laxity with evidence of improved patient-reported outcomes in the long term, but also higher re-operation rates.

When Do Patients Improve After Hip Arthroscopy for Femoroacetabular Impingement? A Prospective Cohort Analysis

BACKGROUND

Hip arthroscopy for femoroacetabular impingement (FAI) has been shown to improve patient outcomes, especially for returning to sport. Although previous studies often evaluated outcomes 2 years after hip arthroscopy, there has been no analysis of the progression of patient improvement over time or with respect to achieving the minimal clinically important difference (MCID).

HYPOTHESIS/PURPOSE

The purpose was to prospectively evaluate changes in patient-reported outcome (PRO) scores during the first 2 years after hip arthroscopy for FAI and to analyze when the MCID is achieved. It was hypothesized that clinically significant changes will be reached by 1 year after surgery.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

Patients undergoing hip arthroscopy for FAI were prospectively enrolled, and they completed the 12-Item Short Form Health survey (SF-12), modified Harris Hip Score, and Hip disability and Osteoarthritis Outcome Score (HOOS) at preoperative baseline and 3 months, 6 months, 1 year, and 2 years after surgery. Mean scores and the percentage of patients reaching the MCID at each time point were analyzed via analysis of variance and Cochrane-Armitage trend tests.

RESULTS

A total of 129 hips from 122 patients were evaluated, revealing significant improvements after hip arthroscopy for FAI (PRO scores increased 19 to 45 points) with 95.8%, 93.6%, and 84.8% of patients achieving the MCID for HOOS-Sports, HOOS-Quality of Life (QoL), and HOOS-Pain, respectively, at 2-year follow-up. Analysis of PRO change showed that for all scores, the greatest improvement occurred from presurgery to postoperative 3 months, with lesser improvements at subsequent 6-month, 1-year, and 2-year time points ( P < .001). The SF-12 physical component score, HOOS-Sports, and HOOS-QoL continued to show statistically significant improvements through 2 years, while other scores plateaued after 3 months. The percentage of patients achieving the MCID for HOOS-Sports, HOOS-QoL, and HOOS-Pain continued to increase over 2 years, but the percentage achieving the MCID did not increase after 3 months for all other scores.

CONCLUSION

Hip arthroscopy for FAI yields significant improvements in patient outcomes within 2 years of surgery. The majority of improvement occurs within 3 months after surgery, but certain outcomes, such as returning to sport, QoL, and pain, can continue to improve through 2 years.

Ultrasound-Guided Percutaneous Peripheral Nerve Stimulation: Neuromodulation of the Femoral Nerve for Postoperative Analgesia Following Ambulatory Anterior Cruciate Ligament Reconstruction: A Proof of Concept Study

Objectives

The purpose of this prospective proof of concept study was to investigate the feasibility of using percutaneous peripheral nerve stimulation of the femoral nerve to treat pain in the immediate postoperative period following ambulatory anterior cruciate ligament reconstruction with a patellar autograft.

Materials and Methods

Preoperatively, an electrical lead (SPRINT, SPR Therapeutics, Inc., Cleveland, OH, USA) was percutaneously implanted with ultrasound guidance anterior to the femoral nerve caudad to the inguinal crease. Within the recovery room, subjects received 5 min of either stimulation or sham in a randomized, double‐masked fashion followed by a 5‐min crossover period, and then continuous active stimulation until lead removal postoperative Day 14–28. Statistics were not applied to the data due to the small sample size of this feasibility study.

Results

During the initial 5‐min treatment period, subjects randomized to stimulation (n = 5) experienced a slight downward trajectory (decrease of 7%) in their pain over the 5 min of treatment, while those receiving sham (n = 5) reported a slight upward trajectory (increase of 4%) until their subsequent 5‐min stimulation crossover, during which time they also experienced a slight downward trajectory (decrease of 11% from baseline). A majority of subjects (80%) used a continuous adductor canal nerve block for rescue analgesia (in addition to stimulation) during postoperative Days 1–3, after which the median resting and dynamic pain scores remained equal or less than 1.5 on the numeric rating scale, respectively, and the median daily opioid consumption was less than 1.0 tablet.

Conclusions

This proof of concept study demonstrates that percutaneous femoral nerve stimulation is feasible for ambulatory knee surgery; and suggests that this modality may be effective in providing analgesia and decreasing opioid requirements following anterior cruciate ligament reconstruction. clinicaltrials.gov: NCT02898103.

Characterizing the recovery trajectories of knee range of motion for one year after total knee replacement

Design: Retrospective analysis of routinely collected clinical data. Objective: This study modeled the recovery in knee flexion and extension range of motion (ROM) over 1 year after total knee replacement (TKR). Background: Recovery after TKR has been characterized for self-reported pain and functional status. Literature describing target knee ROM at different follow-up periods after TKR is scarce. Methods: Data were extracted for patients who had undergone TKR at a tertiary care hospital at 2, 8, 12, 26, and 52 weeks after TKR. A linear mixed-effects growth model was constructed that investigated the following covariates age, sex, pre-TKR range, body mass index, duration of symptoms, and their interaction with weeks post TKR. Results: Of the 559 patients included (age 64.8 ± 8.5 years), 370 were women and 189 were men. Knee ROM showed the greatest change during the first 12 weeks after TKR, plateauing by 26 weeks. For an average patient, knee flexion increased from approximately 100º 2 weeks post TKR to 117º 52 weeks post TKR. Knee extension increased from approximately 3º knee flexion 2 weeks post TKR to 1º flexion 52 weeks post TKR. Conclusions: The results showed that the maximum gains in knee ROM should be expected within the first 12 weeks with small changes occurring up to 26 weeks after TKR. In addition, age and presurgery knee ROM are associated with the gains in knee ROM and should be factored into the estimation of expected knee ROM at a given follow-up interval after TKR.

What's New in Pediatric and Adolescent Anterior Cruciate Ligament Injuries?

BACKGROUND

Anterior cruciate ligament (ACL) tears in children and adolescent patients are being diagnosed and treated at an ever-increasing rates. We performed a review of recent literature regarding care of children and adolescent athletes with an ACL injury.

METHODS

PubMed database was searched for all papers related to treatment of children and adolescents with ACL injuries from October 1, 2012 to September 30, 2015, yielding 114 publications.

RESULTS

A total of 59 papers were found to have contributed important new findings. Papers were selected based on new findings in the following categories: epidemiology, anatomy, risk factors, sex disparity, prevention, surgical outcomes, timing and associated pathologies, and rehabilitation and return to sport.

CONCLUSIONS

Pediatric ACL injuries continue to rise and there are multiple surgical procedures that restore clinical function with good outcomes. Early surgical treatment is favored to prevent concomitant articular injuries. Early return to play can increase risk of reinjury and should be met with caution in this age group. Prevention strategies should be further studied and implemented in hopes of decreasing the incidence of this injury and the long-term potential damage.

Preoperative Short Form Health Survey Score Is Predictive of Return to Play and Minimal Clinically Important Difference at a Minimum 2-Year Follow-up After Anterior Cruciate Ligament Reconstruction

BACKGROUND

There is increased interest in understanding the preoperative determinants of postoperative outcomes. Return to play (RTP) and the patient-reported minimal clinically important difference (MCID) are useful measures of postoperative outcomes after anterior cruciate ligament reconstruction (ACLR).

PURPOSE

To define the MCID after ACLR and to investigate the role of preoperative outcome scores for predicting the MCID and RTP after ACLR.

STUDY DESIGN

Case-control study; Level of evidence, 3.

METHODS

There were 294 active athletes enrolled as part of an institutional ACL registry with a minimum 2-year follow-up who were eligible for inclusion. A questionnaire was administered to elicit factors associated with RTP. Patient demographic and clinical data as well as patient-reported outcome measures were captured as part of the registry. Outcome measures included the International Knee Documentation Committee (IKDC) subjective knee evaluation form, Lysholm scale, and 12-Item Short Form Health Survey (SF-12) physical component summary (PCS) and mental component summary (MCS). Preoperative outcome score thresholds predictive of RTP were determined using a receiver operating characteristic (ROC) with area under the curve (AUC) analysis. The MCID was calculated using a distribution-based method. Multivariable logistic models were fitted to identify predictors for achieving the MCID and RTP.

RESULTS

At a mean (±SD) follow-up of 3.7 ± 0.7 years, 231 patients were included from a total 294 eligible patients. The mean age and body mass index were 26.7 ± 12.5 years and 23.7 ± 3.2 kg/m², respectively. Of the 231 patients, 201 (87.0%) returned to play at a mean time of 10.1 months. Two-year postoperative scores on all measures were significantly increased from preoperative scores (IKDC: 50.1 ± 15.6 to 87.4 ± 10.7; Lysholm: 61.2 ± 18.1 to 89.5 ± 10.4; SF-12 PCS: 41.5 ± 9.0 to 54.7 ± 4.6; SF-12 MCS: 53.6 ± 8.1 to 55.7 ± 5.7; P < .001 for all). The corresponding MCID values were 9.0 (IKDC), 10.0 (Lysholm), 5.1 (SF-12 PCS), and 4.3 (SF-12 MCS). Preoperative score thresholds predictive of RTP were the following: IKDC, 60.9; Lysholm, 57.0; SF-12 PCS, 42.3; and SF-12 MCS, 48.3. These thresholds were not independently predictive but achieved significance as part of the multivariable analysis. In the multivariable analysis for RTP, preoperative SF-12 PCS scores above 42.3 (odds ratio [OR], 2.73; 95% CI, 1.09-7.62) and SF-12 MCS scores above 48.3 (OR, 4.41; 95% CI, 1.80-10.98) were predictive for achieving RTP; an ACL allograft (OR, 0.26; 95% CI, 0.06-1.00) was negatively predictive of RTP. In the multivariable analysis for the MCID, patients with higher preoperative scores were less likely to achieve the MCID ( P < .0001); however, a higher preoperative SF-12 MCS score was predictive of achieving the MCID on the IKDC form (OR, 1.27; 95% CI, 1.11-1.52) and Lysholm scale (OR, 1.08; 95% CI, 1.00-1.16). Medial meniscal injuries, older age, and white race were also associated with a decreased likelihood for achieving the MCID.

CONCLUSION

Preoperative SF-12 MCS and PCS scores were predictive of RTP after ACLR; patients scoring above 42.3 on the SF-12 PCS and 48.3 on the SF-12 MCS were more likely to achieve RTP. Additionally, we defined the MCID after ACLR and found that higher SF-12 MCS scores were predictive of achieving the MCID on knee-specific questionnaires.

How are we measuring clinically important outcome for operative treatments in sports medicine?

OBJECTIVES

Minimal clinically important difference (MCID) and other measures of minimum clinical importance are increasingly recognized as important clinical considerations for evaluating the efficacy of an intervention. As our interpretation of clinical outcome evolves beyond statistical significance, psychometric properties such as MCID will be increasingly important to various stakeholders in the orthopaedic community. The purpose of this study was to: 1) describe the state of clinically important outcome reporting and 2) describe the methods used to derive these psychometric values for sports medicine patients undergoing operative treatments.

METHODS

A review of the MEDLINE database was performed. Studies primarily deriving and reporting clinically important outcome measures for operative interventions in sports medicine were included. Demographic, methodological and psychometric properties of included studies were extracted. Level of Evidence and the Newcastle Ottawa Scale (NOS) were used to assess study quality. Statistical analysis was primarily descriptive.

RESULTS

Fifteen studies met inclusion criteria; 10 of the 15 studies were Level II evidence and mean NOS score was 5.3/9. Minimal detectable change (MDC) was the most commonly derived measure of clinical importance, calculated in 53.3% of studies, followed by MCID, calculated in 40.0% of studies. A combination of distribution and anchor-based methods was the most commonly used method to determine clinical importance (N = 7, 46.7%) followed by distribution only (N = 5, 33.3%). Predictors of clinically important change were reported in four studies and were most commonly related to pre-operative functional score.

CONCLUSIONS

MDC and the MCID are the most commonly reported measures of clinically important outcome after operative treatment in sports medicine. A combination of both distribution and anchor-based methods is commonly used to derive these values. More attention should be paid to reporting outcomes that are clinically important and developing guidelines for reporting clinical meaningful outcome.

Kinesio taping as a treatment method in the acute phase of ACL reconstruction: A double-blind, placebo-controlled study

OBJECTIVE

In this study, we aimed on investigating the effects of Kinesio taping (KT) in acute postoperative rehabilitation phase of anterior cruciate ligament (ACL) reconstruction.

METHODS

Thirty male patients (mean age: 28.1 years) with ACL reconstruction were randomly assigned to two groups: (1) an experimental group to receive a KT treatment through the muscle and lymphatic correction techniques; or (2) a control group for sham KT. Both interventions were applied twice during a 10-day period from the fourth postoperative day. All patients received the same rehabilitation program for three months. The groups were compared according to range of motion (ROM), pain, swelling and muscle strength before treatment and on the fifth and tenth treatment days. Subjective evaluations were made with the Lysholm, modified Cincinnati and Tegner scores on the first and third postoperative months.

RESULTS

Intragroup comparisons showed significant improvements in both groups on the fifth and tenth day and first and third month evaluations (p < 0.05). In comparison to the control group, the experimental group showed significant improvements in swelling around the patella, all pain measurements and hamstring muscle strength on the fifth KT day and knee flexion range of motion (ROM), night pain, all swelling measurements and hamstring muscle strength on the tenth KT day (p < 0.05).

CONCLUSION

Our results revealed that KT techniques applied in addition to the acute rehabilitation program of ACL reconstruction are beneficial in treatment of pain, swelling, knee flexion ROM, and hamstring muscle strength.
