Anterior Cruciate Ligament (ACL) injuries are among the most common knee injuries, affecting athletes and individuals of all ages. While surgical reconstruction has been the conventional approach for decades, recent research has shed light on the efficacy of non-surgical management strategies. Drawing upon contemporary evidence, including findings from landmark studies such as the Oslo-Delaware studies and the KANON trial, this blog post explores the latest advancements in non-surgical management of ACL injuries.
Â
The Oslo-Delaware Studies:
The Oslo-Delaware studies, conducted in collaboration between Norwegian and American researchers, have provided valuable insights into the natural history and outcomes of ACL injuries treated conservatively. These longitudinal cohort studies followed individuals with ACL tears who opted for non-surgical management over a period of several years. The findings revealed that a substantial proportion of patients achieved satisfactory outcomes with conservative management, including a return to pre-injury activity levels, stability, and function, without the need for surgical intervention.
Â
Key findings from the Oslo-Delaware studies include:
1. Many individuals with ACL tears can adapt and function well with conservative management, particularly those with lower activity levels or less demanding functional requirements.
2. Factors such as age, activity level, knee stability, and the presence of concomitant injuries may influence the decision-making process regarding non-surgical versus surgical management.
3. Close monitoring, rehabilitation, and patient education are essential components of non-surgical management, aimed at optimising knee function, stability, and long-term outcomes.

The KANON Trial:
The KANON trial is a landmark randomised controlled trial that compared outcomes between non-surgical and surgical management of acute ACL tears. Conducted in Sweden, the KANON trial provided robust evidence regarding the efficacy of non-surgical interventions, including early rehabilitation, exercise therapy, and functional bracing, in individuals with ACL injuries.
Â
Key findings from the KANON trial include:
1. Non-surgical management, consisting of structured rehabilitation and functional bracing, yielded comparable outcomes to surgical reconstruction in terms of knee function, stability, and patient-reported outcomes.
2. Individuals managed non-surgically experienced similar rates of return to pre-injury activity levels and satisfaction with their knee function compared to those who underwent surgery.
3. Early initiation of rehabilitation and a progressive exercise program tailored to the individual's needs were crucial aspects of successful non-surgical management.

Advancements in Non-Surgical Management:
Building upon the insights from the Oslo-Delaware studies and the KANON trial, recent advancements in non-surgical management of ACL injuries focus on early rehabilitation, neuromuscular training, biomechanical interventions, and patient-centered care principles. Physiotherapists play a pivotal role in delivering evidence-based rehabilitation programs tailored to the individual's needs, goals, and functional requirements.
Â
Conclusion:
Recent evidence from landmark studies such as the Oslo-Delaware studies and the KANON trial has challenged the traditional paradigm of surgical intervention for ACL injuries, highlighting the effectiveness of non-surgical management approaches. By integrating contemporary evidence into clinical practice, physiotherapists can offer comprehensive and evidence-based care to individuals with ACL injuries, promoting optimal outcomes and enhancing patient satisfaction. If you or someone you know is dealing with an ACL injury, consider consulting with a qualified physiotherapist who can assess your condition, discuss your treatment options, and develop a personalised rehabilitation plan tailored to your needs and goals.
