UNLABELLED: PUSPOSE OF THE STUDY. Many studies have investigated the efficacy of peroneus longus tendon (PLT) in anterior cruciate ligament (ACL) reconstruction, and donor site morbidity has not been adequately studied. MATERIAL AND METHODS: Fifty patients who underwent ACL reconstruction using PLT were included. Ankle strengths of the patients evaluated with an analog dynamometer. Ankle range of motion (ROM) was measured with a smart phone inclonometer application. RESULTS: There was no significant difference between the postoperative ankle strength(eversion, plantar flexion) in the donor area and the preoperative period (p=0.6 and p=0.7, respectively) and contralateral healthy side (p=0.6, p=0.6, respectively). Ankle ROM angles (dorsiflexion, plantar flexion, eversion, inversion) were significantly lower in the post-operative period compared to the preoperative period and contralateral healthy side (p<0.05, p<0.05, p<0.05, p<0.05, respectively). There was no significant difference between pre-operative and post-operative AOFAS scores (p=0.2). CONCLUSIONS: Although PLT can affect ROM angles, it is a promising alternative for ACL reconstructions without causing functional morbidity. KEY WORDS: peroneus longus tendon, autograft, anterior cruciate ligament reconstruction, donor site morbidity.

OBJECTIVES: This study aimed to investigate the impact of SportsMetrics programs on knee and ankle kinematics, as well as knee-ankle coupling responses during double leg landings among female athletes with dynamic knee valgus (ligament dominance). METHODS: Eighty-four female athletes, including 30 volleyball players, 30 basketball players, and 24 soccer players, were randomly divided into two equal training (TG) and a control groups (CG). The TG underwent 18 sessions of SportsMetrics exercises, while the CG maintained their regular exercise routine. Dynamic knee valgus, lower limb kinematics, and coordination were assessed using the double leg squat and landing error scoring system tests. MAIN OUTCOME MEASURES: The main outcome measures encompassed knee sagittal and frontal kinematics, ankle sagittal kinematics, as well as knee-ankle coordination and its variability. RESULTS: Significant reduction in knee range of motion in the frontal plane was observed across all three sports during landing. The SportsMetrics program tailored for basketball players led to a specific increase in knee flexion. CONCLUSION: The implementation of SportsMetrics effectively modifies ACL injury risk factors, addressing dynamic knee valgus and landing techniques in female athletes. Female athletes displaying dynamic knee valgus are advised to incorporate sport-specific SportsMetrics programs into their training regimens for optimal results.

The aim of this study was to examine the effect of attentional focus instructions on the biomechanical variables associated with the risk of anterior cruciate ligament injury of the knee joint during a drop landing task using a time series analysis. Ten female volleyball players (age: 20.4 ± 0.8 years, height: 169.7 ± 7.1 cm, mass: 57.6 ± 3.1 kg, experience: 6.3 ± 0.8 years) performed landings from a 50 cm height under three different attentional focus conditions: (1) external focus (focus on landing as soft as possible), (2) internal focus (focus on bending your knees when you land), and (3) control (no-focus instruction). Statistical parameter mapping in the sagittal plane during the crucial first 30% of landing time showed a significant effect of attentional focus instructions. Despite the similarity in landing performance across foci instructions, adopting an external focus instruction promoted reduced vertical ground reaction force and lower sagittal flexion moment during the first 30% of execution time compared to internal focus, suggesting reduced knee loading. Therefore, adopting an external focus of attention was suggested to reduce most biomechanical risk variables in the sagittal plane associated with anterior cruciate ligament injuries, compared to internal focus and control condition. No significant differences were found in the frontal and horizontal planes between the conditions during this crucial interval.

Najčastejším symptomatickým prejavom syndrómu iliotibiálneho traktu (ITBS – iliotibial band syndrome) je bolesť bočnej časti kolena, ktorá je spojená s opakovanými pohybovými aktivitami. Pacienti bolesť často udávajú ako bodavú v oblasti okolo laterálneho femorálneho epikondylu, ktorá môže vyžarovať dole iliotibiálnym smerom do holennej kosti. V proximálnej časti stehna dostáva iliotibiálny trakt (ITB) fasciálne časti z hlbokej fascie stehna, m. gluteus maximus a m. tensor fasciae latae. ITBS sa vo väčšine prípadov úspešne lieči neoperačným manažmentom, hoci niekedy je potrebný chirurgický zákrok. Etiológia ITBS je predmetom kontroverzných diskusií. Pre ITBS bolo navrhnutých niekoľko etiológií, vrátane trenia ITB o laterálny femorálny epikondyl, kompresie tukového tkaniva a spojivového tkaniva a chronický zápal burzy ITB. ITBS je diagnóza založená na klinickom prejave. Dôležitým nálezom pri klinickom vyšetrení je lokálna citlivosť laterálnej časti kolena pod epikondylom a nad kĺbovou líniou. Rehabilitácia u pacientov so ITBS predstavuje dôležitú časť komplexnej liečby, ktorá zohráva kľúčovú úlohu pri liečbe ITBS.
Summary: The most common symptomatic manifestation of iliotibial band syndrome (ITBS) includes pain in the lateral part of the knee, which is associated with repetitive movement activities. Patients often describe pain in the area around the lateral femoral epicondyle, which can radiate down the iliotibial direction into the tibia. In the proximal part of the thigh, the iliotibial tract (ITB) receives fascial parts from the deep fascia of the thigh, gluteus maximus, and tensor fasciae latae. ITBS is often successfully treated with non-operative management, although surgery is sometimes required. The etiology of ITBS has been the subject of controversial discussions. Various etiologies have been proposed for ITBS, including friction of the ITB against the lateral femoral epicondyle, compression of the adipose tissue and the connective tissue, and chronic inflammation of the ITB bursa. ITBS is a diagnosis based on clinical presentation. Local tenderness of the lateral part of the knee below the epicondyle and above the joint line is an important finding during physical examination. Rehabilitation in patients with ITBS is an important part of comprehensive treatment that plays a key role in the therapy of ITBS.

After anterior cruciate ligament (ACL) injury, a decrease in muscle strength associated with muscle atrophy is frequently observed. The temporal and spatial effects of reconstructive surgery on muscle atrophy have not been examined in detail. This study aimed to 1) reveal the short and mid-term effects of reconstructive surgery on muscle atrophy, and 2) investigate the differences in the degree of atrophy after ACL reconstruction in the hindlimb muscles. ACL transection with or without reconstructive surgery was performed unilaterally on the knees of rats. Untreated rats were used as controls. At one or four weeks post-surgery, the relative muscle wet weights (wet weight/body weight) of the hindlimb muscles were calculated to assess atrophy. At one week post-surgery, muscle atrophy was induced by ACL transection and further aggravated by reconstructive surgery. Reconstructive surgery facilitated recovery from muscle atrophy in some muscles compared with those without reconstructive surgery (ACL transection alone) at four weeks post-surgery. Muscle atrophy after ACL reconstruction was greater in the rectus femoris and plantar flexors than in the semitendinosus and plantar extensors at one week post-surgery. These results indicate that reconstructive surgery exacerbates muscle atrophy in the first week post-surgery, while facilitating recovery between the first and fourth week post-surgery. After reconstructive surgery, muscle atrophy was observed not only in the quadriceps and hamstrings, but also in the lower leg muscles, suggesting the need for muscle strengthening interventions for the lower leg muscles as well as the quadriceps and hamstrings.

OBJECTIVES: Compare overall Landing Error Scoring System (LESS) scores, risk categorisation, specific LESS errors, and double-leg jump-landing jump heights between overhead goal and no goal conditions. DESIGN: Randomised cross-over. SETTING: Laboratory. PARTICIPANTS: 76 (51% male). MAIN OUTCOME MEASURES: Participants landed from a 30-cm box to 50% of their body height and immediately jumped vertically for maximum height. Participants completed three trials under two random-ordered conditions: with and without overhead goal. Group-level mean LESS scores, risk categorisation (5-error threshold), specific landing errors, and jump heights were compared between conditions. RESULTS: Mean LESS scores were greater (0.3 errors, p < 0.001) with the overhead goal, but this small difference was not clinically meaningful. Similarly, although the number of high-risk participants was greater with the overhead goal (p = 0.039), the 9.2% difference was trivial. Participants jumped 2.7 cm higher with the overhead goal (p < 0.001) without affecting the occurrence of any specific LESS errors. DISCUSSION: Performing the LESS with an overhead goal enhances sport specificity and elicits greater vertical jump performances with minimal change in landing errors and injury-risk categorisation. Adding an overhead goal to LESS might enhance its suitability for injury risk screening, although the predictive value of LESS with an overhead goal needs confirmation.
