Abstract:

BACKGROUND: Anterior and posterior cruciate ligament injury combined with Ⅲ degree medial collateral ligament injuries has damage to the stability of the knee joint, short-term efficacy has been confirmed, but the medium-term efficacy is not plausible.
OBJECTIVE: To assess the medium-term efficacy after multi-ligaments injury reconstruction.
METHODS: A total of 40 patients with anterior and posterior cruciate ligament injury combined with Ⅲ degree medial collateral ligament injuries were selected (30 males, 10 females, age from 19-48 years old). All the patients with anterior and posterior cruciate ligament injury received allogeneic tendon reconstruction under arthroscopy, and the patients with medial collateral ligament injury were repaired with rivet. The Lachman test, IKDC classification, Lysholm scores and KT-1000 value were performed before and after surgery to evaluate the efficacy of reconstruction.
RESULTS AND CONCLUSION: A total of 40 cases were followed-up for 60 months. All preoperative symptoms got better apparently, such as the pain of the knee joint, swelling and limitation of range of motion. The Lachman test, IKDC classification, Lysholm scores and KT-1000 value after reconstruction were significantly increased when compared with that prior to surgery (P < 0.05). The results demonstrate that allogeneic tendon reconstruction of anterior and posterior cruciate ligaments and reconstruction of medial collateral ligament with rivet can recovery the stability and knee function, It also has advantages in short-term efficacy and medium-term efficacy.
