Abstract
BackgroundThe objective of this study is to describe the rehabilitative pathway of patients undergoing endoprosthetic knee replacement surgery, build reference values of the functional results achieved, and identify possible prognostic factors.MethodsProspective observational study. All patients undergoing resection and knee replacement surgery using a modular prosthesis following bone tumor resection were consecutively recruited over the last 2 years. The patients were followed for a period of 1 year, the result values were collected at 3, 6 and 12 months.ResultsIn total, 30 patients were enrolled. The median age was 19 years with 33% of patients being female. Median values recorded for knee flexion, quadriceps strength, Toronto Extremity Salvage Score, Time Up and Go and Six Minutes Walking Test showed an improvement of 16, 25, 18, 48 and 38% from 3 to 12 months, respectively. The level and width of the resection were correlated with the mobility of the knee and the strength of the quadriceps.ConclusionPatients undergoing knee replacement for bone tumors were able to achieve satisfactory functional outcomes from the first postoperative year. A specific assessment of outcomes can be conducted to facilitate the management of patient expectations. A very wide resection and interventions of the proximal tibia are risk factors for a poorer functional outcome.
Highlights
The objective of this study is to describe the rehabilitative pathway of patients undergoing endoprosthetic knee replacement surgery, build reference values of the functional results achieved, and identify possible prognostic factors
With the improvement of diagnostic techniques, chemotherapy treatments and reconstructive techniques, most of these patients can be treated with a modular prosthesis after bone resection [4]; the 5-year survival rate
The objective of the present study was to describe the rehabilitative pathway of patients undergoing knee replacement with modular prosthesis for bone tumour, as well as building reference values of the functional results achieved in the consecutive rehabilitative phases (3, 6, and 12 months) to identify possible prognostic factors
Summary
The objective of this study is to describe the rehabilitative pathway of patients undergoing endoprosthetic knee replacement surgery, build reference values of the functional results achieved, and identify possible prognostic factors. Shehade et al [14] attempted to describe and outline specific rehabilitation protocols for the different locations of the tumor They concluded by advocating the use of standardized guidelines, as they can lead to an improvement in the final functional results. The objective of the present study was to describe the rehabilitative pathway of patients undergoing knee replacement with modular prosthesis for bone tumour, as well as building reference values of the functional results achieved in the consecutive rehabilitative phases (3, 6, and 12 months) to identify possible prognostic factors
