Surgical treatment of grade III collateral ligament injury of knee joint caused by military training

Objective To explore the method and effect of surgical treatment on grade Ⅲ collateral ligament injuries caused by military training.Methods Sixteen cases of grade Ⅲ collateral ligament injuries caused by military training were involved in the present study.Injuries to insertion of collateral ligament was repaired with suture anchor,fresh rupture of medial collateral ligament parenchyma was sutured directly,old rupture of medial collateral ligament parenchyma was repaired by direct suture and strengthening with autologous semitendinosus-gracilis tendon graft,while both fresh and old rupture of lateral collateral ligament parenchyma was reconstructed with autologous semitendinosus-gracilis tendon graft.Knee function was assessed 1 year after operation by Lysholm scores and compared with that before the operation.Results All the 16 patients were followed-up for 12 to 33 months with a mean of 20.5 months.The Lysholm knee scores of 1 year after peration(92.45±4.03) was significantly higher than that before operation(56.45±11.03,P0.05).Conclusions For the grade Ⅲ collateral ligament injuries caused by military training,the treatment principle was early diagnosis and early operation,and different surgical methods should be used according to the injury types for the sake of obtaining best therapeutic effects.
