 Name CLINICAL OUTCOME AND TUNNEL WIDENING AFTER HAMSTRING ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION. A PROSPECTIVE RANDOMIZED COMPUTED TOMOGRAPHY - BASED TRIAL APERTURE WITH CORTICAL FIXATION
 Study Type PROSPECTIVE CONTROLLED RANDOMIZED
 Question The purpose of this randomized controlled trail is to determine the influence of two different fixation methods on TW and clinical outcome after anatomic ACL reconstruction using hamstring graft in young and active patients. We hypothesize the fixation close to the joint using Biocomposite screws results in less TW compared to extracortical ACL Tightrope fixation.

Name ABSORBATION AND OSTEOCONDUCTIVITY OF THE BIOCOMPOSITE INTERFERENCE SCREW (30% BCP AND 70% PLDLA, ARTHREX) AND THE PLLA INTERFERENCE SCREW (Poly-L-Lactid-Acid, ARTHREX) IN ACL-RECONSTRUCTION.
Study Type Prospective randomized study
Question The primary aim of this study is to compare the absorbtion and osteoconductivity of biocomposite interference screw (30% BCP and 70% PLDLA, Arthrex) and the PLLA interference screw (poly-l-lactid-acid, Arthrex) in anatomical single bundle ACL reconstruction using tibial and femoral aperture fixation of a hamstring autograft.
In vivo Degradation and Osteoconductivity will be measured on CT and MRI scans.
Second aim is to compare the Functional outcome with the objective and subjective IKDC and the KT 1000 Arthrometer. The follow up time will be 3 years.

Name ELASTIC STABLE INTRAMEDULLARY NAILING VS LOCKING COMPRESSION PLATE OSTEOSYNTHESIS IN COMMINUTED DISPLACED MIDSHAFT CLAVICULAR FRACTURES
Study Type CONTROLLED RANDOMIZED, TWO CENTER STUDY
Question The primary aim of this study is to compare elastic stable intramedullary nailing vs locking compression plate osteosynthesis in comminuted displaced midshaft clavicular fractures according to complication rate, functional outcome, healing time and patients satisfaction.

Name Total Knee Arthroplasty (TKA) after Patellectomy
Study Type Biomechanical study on human cadavers
Question Inferior results are reported in patients after previous patellectomy and TKA. Especially higher rates of aseptic loosening, instability and dissatisfaction are problematic in this group of patients. It is unclear if PCL retaining implants are sufficient or if PCL sacrificing implants should be used. The aim of this study is to investigate the biomechanical forces applied to different TKA designs to give a clinical recommendation, which implants are best used in patients after patellectomy

Name MACT (Matrix-associated autologous chondrocyte transplantation)
Study Type Observational retrospective open cohort study
Question To determine the clinical and radiological outcome after cartilage repair surgery on the knee joint. In study we evaluate the outcome in follow-up intervals up to 5 year using multiple clinical scores as well as cartilage-sensitive MRI.
The following questions will be addressed:
- Different outcomes after MACT regarding males and females?
- Outcome after MACT influenced by the patient's age?
