Alveolar ridge preservation with a xenograft (Bio-Oss® Collagen) and a collagen matrix (Mucograft® Seal) or a free connective tissue graft versus spontaneous healing:*A 5-year follow up

The aim of this study is to evaluate esthetic and clinical outcomes and patient satisfaction following single-tooth replacement in the anterior maxilla in patients treated with a xenograft and a collagen matrix or a free connective tissue graft…

Migration in a Cruciate Retaining and a Condylar Stabilizing Insert of a robot-assisted Uncemented Total Knee Prosthesis using Model-based RSA: a Mono-Center Randomized Controlled Trial with 10 years follow-up

The primary objective is to compare the migration of both the femoral and tibial component by the use of a CS insert or CR insert both made of HXPLE using model-based roentgen stereophotogrammetric analysis (mRSA). Furthermore, the safety and…

Capsular closure versus unrepaired capsulotomy after hip arthroscopy

The main objective is to measure the effect of capsular repair versus unrepaired capsulotomy at the end of the procedure on early postoperative pain. This is measured with the use of NRS pain scores weekly by patient diary and 1 year postoperative.…

Stability of the Journey II XR total knee system, measured with RSA

The main objective is to investigate the fixation of the Journey II XR BCR TKA in terms of micromotion of the femoral and tibial components over time measured by RSA. Secondary, this study aims to assess the effect of this BCR TKA on daily life…

Effectiveness of pain neuroscience education on pain after total knee arthroplasty: a randomised controlled trial

The main objective is to compare the effectiveness of two sessions PNE versus care as usual on pain levels 3 months after surgery in patients undergoing TKA. Secondary objective(s) is to explore the effectiveness of two sessions PNE in comparison to…

Gait Analysis in short and conventional stems in total hip arthroplasty in varus and valgus hips.

The main objective is to identify variations in the peak hip abduction moment after total hip arthroplasty with either the Optimys or the CBH in varus and valgus hips. Secondary objective are other kinematic and spatiotemporal parameters. Also, a…

Patient-specific cutting blocks to improve tibial tubercle transfer surgery for patients with patellar instability

The primary goal of the current research is to determine the accuracy of the procedure using patient-specific cutting guide. Secondary endpoints are surgical time needed and the guides* fit onto the patients* tibia.

Midflexion Instability and Functional Outcome after TKA: Flexion First Balancer versus Measured Resection technique. The MIFO study

Primairy objective: to prove there is a difference in midflexion laxity between the Flexion First Balancer group compared to the matched control group.Secondary objective: to prove there is a difference in the functional outcome (6 minute walktest,…

Long-term follow up of treatment for carpometacarpal thumb joint osteoarthritis: trapeziectomy with ligament reconstruction and/or tendon interposition versus pyrocarbon disc interposition

Comparative observational cohort study for the long term results after two different treatments for CMC thumb joint OA. We want to compare trapeziectomy with ligament reconstruction and/or tendon interposition with the pyrocarbon disc interposition…
