Distal biceps tendon ruptures are relatively rare. Patients are usually middle-aged men involved in heavy labor. Patients usually present with the history of a pop and a proximal migration of the biceps muscle belly. Clinical exam should be sufficient to diagnose a complete rupture. Several specific tests have been described. Ultrasound scanning or MRI can help confirm the diagnosis. Radiographs are not needed to diagnose distal biceps tendon rupture but may show typical findings. Imaging, more specifically the flexion-abduction-supination (FABS) view MRI, is particularly helpful in the case of a partial rupture or chronic rupture of the distal biceps tendon. Results of surgical reinsertion of the distal biceps have been shown to be superior to conservative treatment. Different techniques and approaches have been described with specific advantages and disadvantages. Primary repair of the tendon is preferred. If this is no longer possible in chronic tears, an augmentation can be done using tendon graft. Results of surgical treatment are good in the vast majority of patients. Reruptures are rare but minor complications are common. Major complications may include posterior interosseous nerve palsy or radioulnar synostosis, but the risk of these complications may be decreased by meticulous attention to detail during surgery.

Introduction. Bicompartmental knee arthroplasty (BKA) addresses combined medial and patellofemoral compartment osteoarthritis, which is relatively common, and has been proposed as a bridge between unicompartmental and total knee arthroplasty (TKA). Case Presentation. We present the case report of a young active man treated with BKA after unsuccessful conservative therapy. Four years later, loosening with fracture of the tibial baseplate was identified and the patient was revised to TKA. Discussion. Although our case is only the second fractured tibial baseplate to be reported, we believe that the modular titanium design, with two fixation pegs, is too thin to withstand daily cyclic loading powers. Light daily routine use, rather than high-impact sports, is therefore advised. Failures may also be related to the implant being an early generation and known to be technically complex, with too few implant sizes. We currently use TKA for the treatment of medial and patellofemoral compartment osteoarthritis.
