— TENPLAOfficial title:
TENSION BAND VERSUS LOCKING PLATE FIXATION FOR THE TREATMENT OF PATELLA FRACTURE - a High Quality, Multicenter, Randomized Clinical Trial
This study is a multicenter pragmatic, prospective, assessor-blinded, randomized independent clinical trial in which we compare locking plate fixation to standard tension band fixation in patients with patella fractures.

Other | Harms | Adverse events, defined as any negative or unwanted reactions to the two groups will be recorded. Based on previous reports we will focus on: infection, DVT and re-operation. Patients are continuously requested to report any suspicion of a potential AE. Furthermore, adverse events (AE) will be recorded at 3-, 6- and 12-months follow-up by asking patients about potential AEs using open-probe questioning to ensure that all AEs are recorded. Furthermore, medical records will be checked at the primary endpoint (12 months) for all AEs occurring from inclusion until the 12 months follow-up. An AE is defined as any undesirable experience during follow-up leading to contact with the healthcare system (general practitioner or hospital). If an AE result in hospitalization, prolonged inpatient hospital care, result in re-surgery, or if an AE is life-threatening, result in death, permanent disability or damage, they will be categorized as serious adverse events (SAEs). | 3-, 6- and 12-months | |
Primary | Knee Injury and Osteoarthritis Outcome Score - (KOOS5) | The Knee Injury and Osteoarthritis Outcome Score (KOOS) 29 is a standardised patient-reported questionnaire developed to evaluate knee problems. The questionnaire includes five subscales: pain, ADL, symptoms, sport and QOL and an overall score KOOS5 can be calculated. A total score of 100 indicates no symptoms, and 0 indicates major symptoms. | One year following treatment | |
Secondary | Knee Injury and Osteoarthritis Outcome Score - (KOOS5) | The Knee Injury and Osteoarthritis Outcome Score (KOOS) 29 is a standardised patient-reported questionnaire developed to evaluate knee problems. The questionnaire includes five subscales: pain, ADL, symptoms, sport and QOL and an overall score KOOS5 can be calculated. A total score of 100 indicates no symptoms, and 0 indicates major symptoms. | 3- and 6 months | |

The questionnaire includes five subscales: pain, ADL, symptoms, sport and QOL and an overall score KOOS5 can be calculated. A total score of 100 indicates no symptoms, and 0 indicates major symptoms. | 3-, 6- and 12-months | |
Secondary | EQ-5D-5L questionnaire (5-level version) | General health will be assessed using EQ-5D-5L questionnaire (5-level version), both the descriptive index and the EQ-VAS. It consists of five dimensions: Mobility, self-care, usual activities, pain/discomfort and anxiety/depression, and a self-rated health scale on a 20 cm vertical, visual analogue scale with endpoints labelled 'the best health you can imagine' and 'the worst health you can imagine'. An Eq5d-5L index of 1.0 indicated full health, 0 death, and -0.59 denoted a condition worse than death. | 3-, 6- and 12-months | |
Secondary | Pain intensity measured on a 10 cm VAS scale | Development in pain will be recorded by patient-reported pain intensity measured on a 10 cm visual analogue scale (VAS) with endpoints "no pain" and "maximal pain" for the worst pain during the last 24 hours and resting pain. | 3-, 6- and 12-months | |
Secondary | "PainDETECT" questionnaire | Knee pain and neuropathic pain will be assessed using the "PainDETECT" questionnaire. The "PainDETECT" screening questionnaire uses a scoring method between 1-38. A total score of 1 indicates no symptoms, and 38 indicates major symptoms. | 3-, 6- and 12-months | |
Secondary | Bone union | Bone union, will be evaluated on standard AP and side X-rays of the fractured patella. The evaluation of bone union will be defined as: i) visible callus formation, diminished no visible fracture line and no pain from the fracture site at weight-bearing and at clinical examination. | 3-, 6- and 12-months | |
Secondary | Maximum isometric knee-extension strength | Maximum isometric knee-extension strength at 60 degrees knee flexion measured as Nm/kg body mass. Will be measured bilaterally by a strap-mounted dynamometer attached to the wall (Mecmesin AFG2500, Mecmesin Ltd, West Sussex, UK) | 12-months | |
Secondary | Maximum isometric knee-flexion strength | Maximum isometric knee-flexion strength at 90 degrees knee flexion measured as Nm/kg body mass. Will be measured bilaterally by a strap-mounted dynamometer attached to the wall (Mecmesin AFG2500, Mecmesin Ltd, West Sussex, UK) | 12-months | |
Secondary | Knee range of motion | Knee range of motion. With the patient supine on an examination table the full range of passive motion in both knee joints will be measured using a standard goniometer. | 3-, 6- and 12-months | |
Secondary | Time to return to work | Measure the time from surgery to end of sick leave measured in days | 3-, 6- and 12-months |
