Clinical Study of Posterolateral Structure of Knee Joint Under Arthroscopy

Clinical Study of Anatomical Reconstruction Technique of Posterolateral Structure of Knee Joint Under Arthroscopy

Objective: To study the clinical effect of anatomical reconstruction of the posterolateral structure of the knee joint under arthroscopy.

Methods: The patients who were admitted to hospital for the treatment of posterolateral structural injuries of the knee joint, including those with other ligament injuries (combined with anterior and posterior cruciate ligament injuries and medial collateral ligament injuries) were subjected to arthroscopic reconstruction of the posterolateral structures. Carry out preoperative and postoperative evaluations, and conduct preoperative and postoperative comparative studies to clarify the clinical effect of the procedure.

Expected results: The anatomical reconstruction technique of the posterolateral structure of the knee joint under arthroscopy may effectively restore the stability and motor function of the knee joint.

Expected conclusion: Arthroscopic anatomical reconstruction of the posterolateral structure of the knee is an effective minimally invasive technique.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
KT2000	Using KT2000 to detect the backward stability of the knee joint after operation, and compare it with the healthy leg	1 year after operation
Lysholm	The Lysholm score consists of eight items including limping, locking, pain, stair climbing, use of supports, instability, swelling, and squatting. The higher values represent a better outcome.	1 year after operation
Tegner	The highest level of activity that you participated in before your injury and the highest level you are able to participate in currently. The higher values represent a better outcome.	1 year after operation
IKDC	International Knee Documentation Committee (IKDC) 2000. The higher values represent a better outcome.	1 year after operation

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
MRI	Using MRI to exam the healing of the posterolateral ligament reconstructed 1 year after surgery	1 year after operation
