Clinically Important Reductions in Physical Function and Quality of Life in Adults with Tumor Prostheses in the Hip and Knee: A Cross-sectional Study.

Clin Orthop Relat Res 2021 May 10. Epub 2021 May 10.

L. Fernandes, M. K. Zebis, Department of Midwifery, Physiotherapy, Occupational Therapy, and Psychomotor Therapy, University College Copenhagen, Copenhagen, Denmark.

Background: Patients with a bone sarcoma who undergo limb-sparing surgery and reconstruction with a tumor prosthesis in the lower extremity have been shown to have reduced self-reported physical function and quality of life (QoL). To provide patients facing these operations with better expectations of future physical function and to better evaluate and improve upon postoperative interventions, data from objectively measured physical function have been suggested.

Questions/purposes: We sought to explore different aspects of physical function, using the International Classification of Functioning, Disability, and Health (ICF) as a framework, by asking: (1) What are the differences between patients 2 to 12 years after a bone resection and reconstruction surgery of the hip and knee following resection of a bone sarcoma or giant cell tumor of bone and age-matched controls without walking limitations in ICF body functions (ROM, muscle strength, pain), ICF activity and participation (walking, getting up from a chair, daily tasks), and QoL? (2) Within the patient group, do ICF body functions and ICF activity and participation outcome scores correlate with QoL?

Methods: Between 2006 and 2016, we treated 72 patients for bone sarcoma or giant cell tumor of bone resulting in bone resection and reconstruction with a tumor prosthesis of the hip or knee. Read More

Prophylactic Antibiotic Regimens In Tumor Surgery (PARITY): a multi-center randomized controlled study comparing alternative antibiotic regimens in patients undergoing tumor resections with endoprosthetic replacements-a statistical analysis plan.

Trials 2021 Mar 22;22(1):223. Epub 2021 Mar 22.

Department of Surgery, McMaster University, Hamilton, ON, L8V 1C3, Canada.

Background: Limb salvage with endoprosthetic reconstruction is the current standard practice for the surgical management of lower extremity bone tumors in skeletally mature patients and typically includes tumor resection followed by the functional limb reconstruction with modular metallic and polyethylene endoprosthetic implants. However, owing to the complexity and length of these procedures, as well as the immunocompromised nature of patients treated with chemotherapy, the risk of surgical site infection (SSI) is high. The primary research objective of the Prophylactic Antibiotic Regimens In Tumor Surgery (PARITY) trial is to assess whether a 5-day regimen of post-operative antibiotics decreases the risk of SSI at 1 year post-operatively compared to a 1-day regimen.

Recycling of flap pedicle in complex lower extremity reconstruction: A proof of free muscle flap neovascularization.

Arch Plast Surg 2020 Nov 15;47(6):619-621. Epub 2020 Nov 15.

Department of Plastic Surgery, The Royal London Hospital, Barts Health NHS Trust, London, UK.

This article portrays the authors' clinical experience of a complex case of lower extremity reconstruction using a recycled pedicle from 10 years old free latissimus dorsi musculocutaneous flap to supply a new free anterolateral thigh flap for proximal tibia wound defect reconstruction. It provides clinical evidence that muscle neovascularization occurs and supports the dogma peripheral tissue neovascularization. This case stipulates that recycling of pedicle is feasible, when used with appropriate strategy and safety and also provides evidence for the long-term survival of greater saphenous vein grafts in lower extremity reconstruction.

Partial Calcaneus Reconstruction using 'Opportunistic Grafts': A Case Report.

J Foot Ankle Surg 2021 Jan-Feb;60(1):199-203. Epub 2020 Sep 3.

Section of Orthopedic Surgery, Department of Surgery, University of Calgary, Calgary, AB, Canada.

Although replantation of an amputated extremity has been successfully performed, occasionally the surgeon is forced to amputate in the case of an unsalvageable open fracture. These appendages can theoretically act as an autologous 'bone and tissue bank' for patients if they have reconstructable contralateral injuries. We present a case of an athlete who sustained a Gustilo and Anderson IIIC injury on 1 leg resulting in a below knee amputation. Read More

Development of a specimen-specific in vitro pre-clinical simulation model of the human cadaveric knee with appropriate soft tissue constraints.

PLoS One 2020 14;15(10):e0238785. Epub 2020 Oct 14.

Institute of Medical and Biological Engineering, School of Mechanical Engineering, Faculty of Engineering and Physical Sciences, University of Leeds, Leeds, United Kingdom.

A human cadaveric specimen-specific knee model with appropriate soft tissue constraints was developed to appropriately simulate the biomechanical environment in the human knee, in order to pre-clinically evaluate the biomechanical and tribological performance of soft tissue interventions. Four human cadaveric knees were studied in a natural knee simulator under force control conditions in the anterior posterior (AP) and tibial rotation (TR) axes, using virtual springs to replicate the function of soft tissues. The most appropriate spring constraints for each knee were determined by comparing the kinematic outputs in terms of AP displacement and TR angle of the human knee with all the soft tissues intact, to the same knee with all the soft tissues resected and replaced with virtual spring constraints (spring rate and free length/degree).
