ABSTRACT
PURPOSE: Degenerative meniscus tears can cause discomfort in some patients, and when medical treatments fail to provide relief, arthroscopy may be considered before resorting to knee prosthesis. However, the benefits of arthroscopy over nonsurgical treatments in patients over 60 years old are limited, and the evidence regarding its overall efficiency and drawbacks remains scarce. Furthermore, there has been no investigation into whether those patients treated with partial meniscectomy, undergo the knee operation at an earlier stage of osteoarthritis. METHODS: This study focused on data from a single Belgian hospital, involving patients over 60 years old with internal meniscal tears. The participants were categorized into two groups based on the treatment they received: arthroscopic partial meniscectomy (APM) or conservative management. The primary outcome assessed was the occurrence of knee arthroplasty within a five year period. Secondary outcomes included evaluating the ICRS cartilage grade and the time taken until total knee arthroplasty (TKA). RESULTS: A total of 194 patients with internal meniscal tears were included in the study. At the 5-year mark, the overall rate of knee arthroplasty was found to be 16.5%, with 11.9% of cases occurring within two years. After the 5-year follow-up, it was observed that 19.2% (24 patients) of the APM group and 11.6% (8 patients) of the conservative management group underwent knee arthroplasty. Notably, patients over 70 years old who underwent APM had a higher risk of eventually requiring TKA compared to those who received conservative management. Additionally, patients who underwent meniscectomy and later underwent TKA showed less wear in the internal compartment of the knee compared to patients in the conservative treatment group who underwent TKA. CONCLUSION: The study suggests that patients who underwent arthroscopy faced a similar risk of knee arthroplasty compared to those who underwent conservative management, excepted for patients over 70 years old. Despite this similar risk of arthroplasty for the whole population, they exhibited lower osteoarthritis severity when compared to the conservative group.

PURPOSE: This study determined at two year follow-up the lifetime risk of re-operation for elderly patients with hip fractures undergoing internal fixation, dual mobility total hip arthroplasty, or bipolar hemiarthroplasty, using death of the patient as a competing risk. MATERIALS AND METHODS: With the hypothesis that arthroplasties may have less complications without increasing mortality even for Garden I and Garden II fractures, we retrospectively reviewed 317 hips with femoral neck fractures operated between January 2015 and August 2019. The mean age at time of surgical intervention was 82.4 years (range 65 to 105). Sixty patients presented a nondisplaced hip fracture (Garden I or II) treated by internal fixtion (I-F), and 257 were treated by hip arthroplasty: 118 dual mobility total hip arthroplasty (DM-THA) and 139 with a bipolar hemiarthroplaty (B-H). Demographics, surgical and complications data, and mortality were collected and compared for each group. RESULTS: The overall mortality rate was 22.4% at two years, and similar (p = 0.98) in all groups, respectively 22%, 22%, and 23% for DM-THA, B-H, and I-F groups. With dual mobility THA, the cumulative incidence of re-operations for any reason was (lower (9%) than with internal fixation (22%) or bipolar hemiarthroplasties (19%). CONCLUSION: Using a double mobility total prosthesis does not increase the post-operative mortality of the patients, nor does it increase their survival. But, reducing the risk of complications certainly improves their quality of life during the little time they have left .
