Bone-patellar tendon autograft is probably the most widely used graft for ACL reconstruction. Several methods for graft fixation have been described. To avoid intra-articular hardware we adopt biological fixation with a femoral conical press-fit fixation. A prospective study was performed on 40 consecutive active athletes who underwent ACL reconstruction with this technique by the same surgeon between November 1994 and September 1995 (mean follow-up 46 months, range 36-62). Results were evaluated by an independent examiner using radiography, computed tomography, subjective and objective evaluation, and isokinetic and functional strength tests. Assessment using the IKDC knee scoring revealed 85% of the patients with a normal or nearly normal knee joint; Tegner's score was 7.5 preoperatively and 6.0 postoperatively, with 60% of the athletes returning to the preinjury sport and level. No patients had instability, with 90% having less than 3 mm side-to-side difference on computerized analysis. The isokinetic test showed mild quadriceps deficit at 3 and 6 months, with no deficit at final follow-up; four patients complained of anterior knee pain and had a positive kneeling test. We found no graft dislocation. All cases showed radiological evidence of graft integration at 3 months time. Long-term results support this technique asx a simple, cost-effective, and reliable alternative for patellar tendon fixation in ACL reconstruction.
Background: Hip arthroplasty is considered the treatment of choice to improve the quality of life of patients affected by degenerative arthritis. The post-op rehabilitation regimen, however, is still a matter of debate. The goal of this study was to perform a systematic review of the available best evidence to provide recommendations for rehabilitation after hip arthroplasty. Materials and methods: Biomedical databases were accessed to identify guidelines, systematic reviews and randomised controlled trials addressing rehabilitation after hip arthroplasty published between 2004 and 2019. Studies were selected and extracted by two independent evaluators with standardised tools. Results: 1 guideline, 8 systematic reviews and 5 randomised controlled trials were included. All included papers were organised according the available evidence of clinical course chronology both in pre- and post-operation rehabilitation up to 6 weeks and thereafter. Although the value of a rehabilitation program after hip arthroplasty is universally recognised, the exact timing and number of sessions is still unknown. A solid literature review allows us to partially answer to this question. Conclusions: Evidence-based rehabilitation recommendations are proposed according to literature research findings. Clinical practice is still somewhat dependent on dogma and traditions, highlighting the need for additional high-quality clinical studies to address areas of uncertainty.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
