Abstract
PURPOSE
Proximal tibia stress fractures present a challenge when performing total knee arthroplasty (TKA) in knee arthritis (KA). The literature on treatment modalities for stress fractures with arthritis is varied and not systematically reviewed. We aimed to answer the questions: (1) Is long-stem TKA sufficient for stress fractures in arthritic knees? (2) Should stress fracture and KA be addressed simultaneously? (3) What is the role of augmentative procedures in stress fractures with knee arthritis? (4) Can a unified algorithm be established?
METHODS
The PubMed and Cochrane databases were searched for keywords such as stress fracture, knee arthritis and total knee arthroplasty, published from January 1995 to 29 May 2022. A total of 472 records were screened down to 13 articles on the basis of our selection criteria. Ten data items were recorded from the included studies. The methodological index for non-randomised studies (MINORS) score for the included studies was 17 ± 3.
RESULTS
We found long-stem TKA to be sufficient for most cases and advocated for single-stage treatment of stress fractures and arthritis. Augmentative procedures play a role in the treatment, and a unified algorithm was drafted to guide treatment.
CONCLUSION
Single-stage management of advanced KA with a stress fracture causes less morbidity than a staged procedure. Long-stem TKA, with or without an augmentative procedure, is an excellent option.
