Aims

The role of high tibial osteotomy (HTO) is being questioned by the use of unicompartmental knee arthroplasty (UKA) in the treatment of medial compartment femorotibial osteoarthritis. Our aim was to compare the outcomes of revision HTO or UKA to a total knee arthroplasty (TKA) using computer-assisted surgery in matched groups of patients.

Patients and Methods

We conducted a retrospective study to compare the clinical and radiological outcome of patients who underwent revision of a HTO to a TKA (group 1) with those who underwent revision of a medial UKA to a TKA (group 2). All revision procedures were performed using computer-assisted surgery. We extracted these groups of patients from our database. They were matched by age, gender, body mass index, follow-up and pre-operative functional score. The outcomes included the Knee Society Scores (KSS), radiological outcomes and the rate of further revision.

The significance of weight in the indications for unicompartmental knee replacement (UKR) is unclear. Our hypothesis was that weight does not affect the long-term rate of survival of UKRs.

We undertook a retrospective study of 212 UKRs at a mean follow-up of 12 years (7 to 22). The patients were distributed according to body mass index (BMI; < vs ≥ 30 kg/m2) and weight (< vs ≥ 82 kg). Kaplan-Meier survivorship analysis was performed and ten-year survival rates were compared between the sub-groups. Multimodal regression analysis determined the impact of the various theoretical contraindications on the long-term rate of survival of UKR.

The ten-year rates of survival were similar in the two weight subgroups (≥ 82 kg: 93.5% (95% confidence interval (CI) 66.5 to 96.3); < 82 kg: 92.5% (95% CI 82.5 to 94.1)) and also in the two BMI subgroups (≥ 30 kg/m2: 92% (95% CI 82.5 to 95.3); < 30 kg/m2: 94% (95% CI 78.4 to 95.9)). Multimodal regression analysis revealed that weight plays a part in reducing the risk of revision with a relative risk of 0.387, although this did not reach statistical significance (p = 0.662). The results relating weight and BMI to the clinical outcome were not statistically significant. Thus, this study confirms that weight does not influence the long-term rate of survival of UKR.

Background

Floating shoulder (FS) is, according to Goss et al, a double disruption of the superior shoulder suspensory complex which usually results from a glenoid neck fracture and a ipsilateral midclavicular fracture. However, the interruption can interest the whole scapular belt from acromion to sterno-clavicular joint. It occurs mostly after a violent traumatism with direct lateral impact on the shoulder. That leads to complex therapeutic issues with sometimes uncertain results.

Material

Between 1984 and 2009, 35 patients (30 men, 5 women), mean age 35 years [16–72] with FS, were treated in our department. Most of them sustained road accident (31cases) with polytraumatism context in 12 cases. A CT scan was realized in the majority of cases to specify the scapular fracture and look for intra-thoracic immediate complications. Mostly, glenoid neck fracture associated with a clavicular fracture has been found out (15cases). Orthopaedic treatment has been realized in 18 cases. Surgical management has been decided for open reduction of sterno-clavicular joint in 2 cases, isolated fixation of the clavicle in 9 cases, of the scapula in 3 cases, and of both scapula and clavicle in 3 cases. Criteria for clinical evaluation were an algo-functional scale (Oxford Shoulder Score, OSS), a subjective Constant Shoulder Score, a functional incapacity scale (Shoulder Simple Test, SST), scales of life quality (DASH and SF12) and global indications (Single Assessment Numeric Evaluation, SANE).
