NCT07088094

Brief Summary

This clinical study investigates the outcomes of bone-patellar tendon-bone and quasi-anatomical meniscus allograft transplantation techniques in patients requiring joint reconstruction. The study aims to assess the safety, efficacy, and functional improvements following these transplant procedures, utilizing donor tissues to restore joint function and alleviate pain in individuals with severe knee damage. Participants will undergo the transplantation procedure and be monitored for post-operative recovery, complications, and long-term outcomes, including joint stability and mobility. The study seeks to provide valuable insights into the effectiveness of these advanced surgical techniques for knee joint repair.

Outcome Measures

Primary Outcomes (3)

  • Incidence of Postoperative Complications Unit of Measure

    Unit of Measure: Percentage of patients with complications (e.g., infection, graft failure, arthrofibrosis) Description: This measure evaluates the incidence of postoperative complications in patients undergoing bone-patellar tendon-bone and quasi-anatomical meniscus allograft transplantation techniques. The complications will be classified according to the Clavien-Dindo Classification for surgical complications, with clinical evaluations using physical examination and imaging to assess the occurrence of adverse events. The results will be reported as the percentage of patients experiencing any form of complication during the postoperative period. Measurement Tool: Clavien-Dindo Classification for surgical complications, clinical evaluation through physical examination, and imaging studies.

  • Functional Improvement in Knee Joint Unit of Measure-Knee Society Score (KSS)

    Unit of Measure: Improvement in functional scores (0-100 scale) Description: This measure evaluates the improvement in knee function following bone-patellar tendon-bone and quasi-anatomical meniscus allograft transplantation techniques. Functional outcomes will be assessed using the Knee Society Score (KSS) What it measures: Knee Score (0-100): Knee-specific symptoms, alignment, stability. Function Score (0-100): Walking distance, stair-climbing, use of aids. Score Meaning: Higher = Better outcome. Note: Reported as two separate scores (not combined). Measurement Tool: Knee Society Score (KSS) and Lysholm Knee Score. The scale use a 0-100 range, where higher scores always indicate better knee function/health.

  • Functional Improvement in Knee Joint Unit of Measure-Lysholm Knee Score

    Unit of Measure: Improvement in functional scores (0-100 scale) Description: This measure evaluates the improvement in knee function following bone-patellar tendon-bone and quasi-anatomical meniscus allograft transplantation techniques. Functional outcomes will be assessed using Lysholm Knee Score. Full Name: Lysholm Knee Scoring Scale Range: 0-100 What it measures: Stability, pain, daily function. Score Meaning: Higher = Better outcome. Measurement Tool: Lysholm Knee Score. The scale use a 0-100 range, where higher scores always indicate better knee function/health.
