Knee Joint

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Summary

Multiligamentous knee injuries (MLKIs) lead to a 65% incidence of knee arthritis. However, reconstruction effectively restores function, with high rates of return to work, sports, and patient satisfaction.

Area of Science:

Orthopedic Surgery
Sports Medicine
Reconstructive Surgery

Background:

Multiligamentous knee injuries (MLKIs) are severe knee trauma.
Arthritis development post-MLKI and functional recovery outcomes require comprehensive evaluation.

Purpose of the Study:

To determine the incidence of knee arthritis following MLKIs.
To assess outcomes such as conversion to total knee arthroplasty (TKA), return to work, return to sports, and patient satisfaction after MLKI reconstruction.

Main Methods:

A systematic literature search was conducted across PubMed, Web of Science, and Scopus databases.
A meta-analysis of seven studies involving patients undergoing MLKI reconstruction was performed.
Pooled incidence rates for arthritis, TKA conversion, return to work, return to sports, and patient satisfaction were calculated using random-effects models.

Main Results:

The pooled incidence of knee arthritis after MLKIs was 65.0% (95% CI 35.4% to 89.4%), with significant heterogeneity.
Conversion to TKA occurred in 9.5% (95% CI: 5.4% to 14.6%) of patients.
High rates were observed for return to work (93.5%), return to sports (70.8%), and patient satisfaction (82.5%).

Conclusions:

MLKIs are strongly associated with a high incidence of post-traumatic knee arthritis.
Despite arthritis development, MLKI reconstruction is an effective intervention for functional recovery, facilitating high rates of return to work, sports, and overall patient satisfaction.
