Background

The goal of patellofemoral arthroplasty (PFA) is to replace damaged cartilage and correct underlying deformities to reduce pain and prevent maltracking. We aimed to determine how PFA modifies patellar height, tilt, and tibial tuberosity-trochlear groove (TT-TG) distance. The hypothesis was that PFA would correct trochlear dysplasia or extensor mechanism malalignment.

Methods

The authors prospectively studied a series of 16 patients (13 women and 3 men) aged 64.9 ± 16.3 years (range 41-86 years) who received PFA. All knees were assessed preoperatively and 6 months postoperatively using frontal, lateral, and “skyline” x-rays, and computed tomography scans to calculate patellar tilt, patellar height, and TT-TG distance.

Results

The interobserver agreement was excellent for all parameters (intraclass correlation coefficient >0.95). Preoperatively, the median patellar tilt without quadriceps contraction (QC) was 17.5° (range 5.3°-33.4°) and with QC was 19.8° (range 0°-52.0°). The median Caton-Deschamps index was 0.91 (range 0.80-1.22) and TT-TG distance was 14.5 mm (range 4.0-22.0 mm). Postoperatively, the median patellar tilt without QC was 0.3° (range ?15.3° to 9.5°) and with QC was 6.1° (range ?11.5° to 13.3°). The median Caton-Deschamps index was 1.11 (range 0.81-1.20) and TT-TG distance was 10.1 mm (range 1.8-13.8 mm).

Conclusion

The present study demonstrates that beyond replacing arthritic cartilage, trochlear-cutting PFA improves patellofemoral congruence by correcting trochlear dysplasia and standardizing radiological measurements as patellar tilt and TT-TG. The association of lateral patellar facetectomy improves patellar tracking by reducing the patellar tilt.  相似文献

Patellofemoral replacement   总被引:2,自引:0,他引:2  
From an analysis of the clinical evaluation of 85 cases and subsequent revisionary procedures, patients for isolated patellofemoral joint replacements should be carefully selected. At the present time, the primary indications are distortion or severe degeneration of the femoral groove.  相似文献

Patellofemoral resurfacing surgery, popular in Europe for the last 25 years, appears to be gaining popularity in the United States.[1] and [36] This is attested by the proliferation of implants that are becoming available in this country. Nevertheless, it remains a niche procedure that is best indicated for patients who are unlikely to develop arthritis in their remaining compartments. Indeed, the worst results have been obtained in patients whose arthritis is of unknown etiology and who are young enough to yet develop clinically significant femorotibial arthritis. On the other hand, the procedure requires far less surgical dissection than a standard total-knee replacement and leads to far less blood loss. This might appeal to patients who would otherwise refuse knee replacement surgery. The key technical points are avoidance of placing the trochlear component too far distally and avoidance of leaving either the proximal or distal portion of the trochlea proud.  相似文献

We review the current status of knowledge in the field of pathogenesis of anterior knee pain in the young patient. Emphasis is placed on newer findings. We have developed what we call the "neural model" as an explanation for the genesis of anterior knee pain. According to our studies we hypothesize that periodic short episodes of ischemia in the lateral retinaculum could be implicated in the pathogenesis of anterior knee pain by triggering neural proliferation of nociceptive axons (substance P-positive nerves), mainly in a perivascular location. Our findings are compatible with the tissue homeostasis theory widely accepted currently to explain the genesis of anterior knee pain.  相似文献

Imaging of the patella and patellofemoral joint cannot be isolated from imaging of the knee anymore than the function of the patellofemoral joint can be separated from the function of the entire knee. Therefore, the current author will focus on imaging of the patellofemoral joint yet integrate this with the entire knee. Because radiographs and other imaging techniques are adjuncts to the history and physical examination, and specifically an extension of the physical examination, each view or technique must be selected thoughtfully to yield the most useful and accurate information possible. Imaging techniques range from relatively inexpensive to very costly, yet the amount of useful information may not show a positive correlation with the cost. Only by integrating the history, physical examination, and the best imaging techniques can the clinician locate the abnormality, determine its cause, and plan a proper course of treatment. Radiographic imaging of the patellofemoral joint requires attention to detail on the part of the technician and knowledge of these techniques on the part of the clinician who orders and interprets the results. Understanding these concepts will help achieve everyone's goal: high-quality and cost-effective orthopaedic care.  相似文献
