The multiligamentary knee injuries are complex high-energy trauma with a devastating prognosis. This injury is rare in older adults whose treatment is controversial. Surgical treatment in older adults may present similar functional results as in younger patients. Present the case of a 75-year-old woman with total posterior cruciate ligament (PCL) rupture, total medial collateral ligament (MCL) rupture and partial anterior cruciate ligament (ACL) rupture with <50% thickness in the right knee. The surgery performed was an arthroscopic reconstruction of the PCL with a posterior tibial allograft and repair of the superficial MCL. The preoperative KOS-ADL score was 42.9% and the postoperative was 81.4% at 18 months of follow-up. The reconstructive surgery in multiligamentary knee injuries is clinically feasible in older adult patients with an acceptable and satisfactory clinical outcome.

The rotator cuff injury is a significant cause of shoulder pain and dysfunction. Treating massive and irreparable rotator cuff tears remains a major challenge for orthopedists due to their complexity and severity. One promising alternative for managing these cases is the use of subacromial balloons. In this study, we present the case of a 67-year-old woman diagnosed with a massive and irreparable rotator cuff tear in her right shoulder (Grade III Patte, Grade IV Goutallier, and Grade II Hamada), without glenohumeral arthritis, intact biceps tenosynovitis, and subscapularis. The preoperative Constant score was 40 points. The patient underwent partial arthroscopic repair of the supraspinatus and infraspinatus tendons, along with a suprapectoral biceps tenodesis and subacromial balloon placement. Postoperative rehabilitation led to improved range of motion, reduced pain, and increased stren...
