TJA in Rare Conditions
- Total knee arthroplasty (TKA) in patients with a prior contralateral above-knee amputation (AKA) is uncommon, with limited literature describing the outcomes. We used a national database to compare the outcomes of primary TKA in above-knee amputees and nonamputees.
- Total knee arthroplasty (TKA) in the setting of a prior contralateral above-knee amputation (AKA) represents a rare scenario with limited reported outcomes. As such, it is difficult for surgeons to effectively counsel these patients relative to risks and expected outcomes after TKA. We report outcomes for a series of 10 such patients.
- Rapidly progressive osteoarthritis (RPO) is a rare condition which is poorly understood. Limited published literature is available. Reported here is a cohort of patients with RPO and acetabular bone loss who underwent primary THA. Risk factors, degree of acetabular bone loss and outcomes are presented. A typical case of RPO is described and investigations discussed. A retrospective audit was undertaken. 49 patients over an 18-year period were included. RPO patients were significantly older (P < 0.01) and had a lower BMI (P = 0.03).
