Is There a Disadvantage to Early Physical Therapy After Multiligament Surgery for Knee Dislocation? A Pilot Randomized Clinical Trial.

Clin Orthop Relat Res 2021 Mar 16. Epub 2021 Mar 16.

G. Hoit, J. Chahal, B. Ravi, D. B. Whelan, Department of Surgery, Division of Orthopaedics, University of Toronto, Toronto, ON, Canada.

Background: Multiligament knee injuries, though rare, can be profoundly disabling. Surgeons disagree about when to initiate rehabilitation after surgical reconstruction due to the conflicting priorities of postoperative stability and motion.

Questions/purposes: (1) Does early or late initiation of physical therapy after multiligament knee surgery result in fewer postoperative manipulations? (2) Does early versus late physical therapy compromise stability postoperatively? (3) Does early initiation of physical therapy result in improved patient-reported outcomes, as measured by the Multi-ligament Quality of Life (ML-QOL) score?

Methods: Between 2011 and 2016, 36 adults undergoing multiligament repair or reconstruction were prospectively enrolled in a randomized controlled trial and randomized 1:1 to either early rehabilitation or late rehabilitation after surgery. Read More

Does the anterolateral ligament protect the anterior cruciate ligament in the most common injury mechanisms? A human knee model study.

Knee 2021 Mar 9;29:381-389. Epub 2021 Mar 9.

Department of Orthopedic Sports Medicine and Arthroscopic Surgery, Hessing Stiftung Augsburg, Augsburg, Germany.

Background: Anterior cruciate ligament (ACL) reconstruction still has a risk of re-rupture and persisting rotational instability. Thus, extra-articular structures such as the anterolateral ligament (ALL) are increasingly treated. The ALL however prevents the internal rotation of the tibia and it must be doubted that the ALL protects the ACL in other common injury mechanisms which primarily include tibial external rotation.

Management and Outcome of a Complex Medial Tibial Plateau Fracture: A Case Report of a Rare Knee Varus Injury Variant.

JBJS Case Connect 2020 10 19;10(4):e19.00626. Epub 2020 Oct 19.

Department of Orthopaedics, Dr. Rajendra Prasad Government Medical College, Kangra, Himachal Pradesh, India.

Case: A 26-year-old patient who had a road traffic accident sustained a complex knee injury, which resulted in a comminuted fracture of the medial tibial plateau, along with undisplaced lateral collateral ligament (LCL) avulsion that was managed surgically with rim plating, resulting in a good outcome after 1-year follow-up.

Conclusion: The authors present a rare case of a combination of axial loading and varus injury to the knee, which caused splaying of the medial tibial plateau with an undisplaced LCL avulsion, managed with single rim plating, which is a relatively new method of fixation that obviated the need for 2 separate implants, with good functional outcome.
