Summary: The present study aimed to evaluate the inter-rater reliability and concurrent validity of using a stopwatch versus force plates for timing the Side Hop Test. The study also sought to determine the number of sessions and trials needed to minimize the effects of learning on the test results. The findings demonstrated that the stopwatch measurements were valid and reliable for measuring the total time of the Side Hop Test, while the limb symmetry index could be reliably assessed after seven familiarization sessions.

Summary: This study aimed to evaluate the muscle strength of knee stabilizer and the symmetry of hamstring fatigue in football players after ACL reconstruction. The results showed that football players who previously met the RTS criteria had deficits in lower-limb muscle performance, which could lead to ACL re-injury. This observation is potentially important as these deficits may not be subjectively reported by athletes and may not be visible in regular assessments.

Summary: This study aimed to investigate the influence of limb dominance on strength and functional outcomes in individuals after ACL reconstruction. The results showed that individuals who injured their nonpreferred jumping limb had significantly lower single-leg forward hop performance, compared to those who injured their preferred jumping limb. Additionally, quadriceps strength and single-leg forward hop performance were correlated with patient self-reported function.

Summary: The study aimed to assess the relationship between knee extensor and flexor LSI values at 4 months post-ACLR and the recommended values at 8 months post-ACLR for RTP, as well as successful RTP after 2 years. Results indicated a significant association between LSI values at 4 months and 8 months post-operation, and successful RTP after 2 years.

Summary: This study aimed to investigate the relationship between single-leg hop distances and knee extensor and flexor strengths at 6 months after reconstruction. The results showed significant correlations between single-leg hop distances and knee strengths, suggesting that appropriate rehabilitation training should be conducted.

Summary: This study investigated the suitability of isometric strength testing methods as an alternative to isokinetic assessment for identifying knee extensor strength asymmetry. The results suggest that isometric methods can be used to assess knee extensor strength in the absence of isokinetic testing equipment, with consideration of test angles being important. ACL reconstruction patients demonstrated greater asymmetry in knee extensor strength compared to healthy controls, highlighting the importance of assessing strength deficits in this population.

Summary: The study showed moderate-to-strong positive correlations between isokinetic knee extension torque and both single-leg hop for distance (SLH) and single-leg vertical jump height (SLVJ) after ACL reconstruction. There were significant side-to-side differences in isokinetic knee extension torque and SLVJ between the operated and unoperated sides. The Limb Symmetry Index (LSI) of SLVJ may be an indicator of the recovery of isokinetic knee extension torque after ACLR.

Summary: The study showed that two consecutive days of military load carriage significantly increased oxygen uptake and reduced knee extensor and flexor torque compared to a single day of load carriage. Therefore, physical training programs aimed at increasing knee extensor strength may help protect against increases in oxygen uptake.

Summary: The study evaluated and compared changes in quadriceps and hamstring strength, as well as single-leg-hop test performance over the first 24 postoperative months in patients who underwent ACLR with BPTB or HT autografts. The results showed that muscle strength and SLH test performance progressively recovered after surgery, but did not fully recover even 24 months postoperatively, with the BPTB group showing inferior quadriceps strength at earlier time points compared to the HT group. However, rehabilitation, whether standard or accelerated, did not significantly impact the recovery of muscle strength and SLH test performance.

Summary: This study investigated the symmetries of hip muscle strength and hop performance after ACL reconstruction. The results showed that men athletes demonstrated symmetrical hop performance and hip muscle strengths, except for hip abductor's maximum voluntary isometric contraction and eccentric peak torque at 60 degrees/s. This indicates that hip muscle strength measures contribute to athletes' hop performances 2 years after ACL reconstruction, suggesting the incorporation of hip muscle strengthening training in rehabilitation programs.

Summary: This study compared the kneeling ability and self-reported knee function of patients with distal tibia fractures managed with either intramedullary nailing (IMN) or open reduction internal fixation (ORIF) with compression plating. The results showed that patients with IMN had significantly worse kneeling function compared to their non-affected limb and the ORIF group. Additionally, the IMN group had worse overall knee function compared to the ORIF group.

Summary: The incidence of mental illness is highest among young adults, especially those in higher education. Many higher education institutions have student support teams that focus on strategies to improve student wellbeing and mental health. However, most of these strategies prioritize clinical therapies and medication, and do not fully utilize exercise as an effective method for addressing mental illness and promoting wellness.

Summary: This study aimed to determine the feasibility and preliminary efficacy of a multi-component physical literacy program for children with neurodevelopmental, emotional, or behavioural challenges. Results indicate that the program is acceptable and well received, with moderate to large effects observed in parent knowledge and confidence. Improvements in children's physical competence were also observed. Thus, the program has the potential to have positive physical and psychological effects when implemented in the community.

Summary: This study aimed to evaluate if age is associated with the risk of short-term complications after ACL reconstruction. The results showed that older patients had higher fragility index scores, shorter operative times, and lower use of general anesthesia. Older age was an independent risk factor for VTE, while younger age was associated with prolonged surgeries.

Summary: This study aimed to determine the minimal clinically important difference (MCID) and the patient acceptable symptoms state (PASS) threshold for the knee injury and osteoarthritis outcome score (KOOS) pain subscore, KOOS physical short form (PS), and KOOS joint replacement (JR) following medial unicompartmental knee arthroplasty (mUKA). The study identified useful values for the MCID and PASS thresholds at 1 year following medial UKA of KOOS pain, KOOS PS, and KOOS JR scores. These values may be used as targets for surgeons when evaluating PROMS using KOOS to determine whether patients have achieved successful outcomes after their surgical intervention.
