Orthopaedics

The Orthopaedic Surgery Department brings together surgeons from different specialties with a common interest in improving the diagnosis and management of musculoskeletal diseases and injuries.

We are currently conducting research into hip and knee replacement, frozen shoulder, rotator cuff tendon disease, acute spinal injuries, musculoskeletal trauma and hand tendon dysfunction and repair.

Sagittal stability in total knee replacement

Goal: Total knee replacement may be stable or unstable in the sagittal plane. Sagittal stability can be measured by Lachman test, anterior drawer KT1000. Sagittal stability is an important factor determining reported outcomes and function.

Comparison of kinematics of two different implant designs after total knee arthroplasty

Kinematics of a medial ball and socket and a single radius cruciate retaining total knee arthroplasty designs were compared using KneeKG in this study.

Proximal femoral anatomy
