Patellar Microfracture: Internal Stabilization House-on-Stilts Technique to Achieve Better Results.

Microfractures are the common first choice for the treatment of osteochondral lesions, because of their high efficacy and low cost and operating time compared with other surgical techniques. Results of microfractures for retropatellar chondral defects are subpar compared with other compartments of the knee, despite the patellofemoral compartment being the second most common compartment for such lesions. One major reason for the inferiority is the mobility of the patella, which is most prominent when the patient's knee is extended, as is the case in this type of surgery.

A simple device in shoulder arthroscopy: the suture assistant.

Arthroscopic reconstructive surgery in the shoulder is an extremely demanding. The advent of suture anchors, arthroscopic knot-tying techniques, and new arthroscopic instruments has greatly facilitated its development. Knowledge of the anatomy and surgical principles alone are not enough.

The peashooter device: an invaluable tool for bone grafting during revision anterior cruciate ligament surgery.

Anterior cruciate ligament (ACL) reconstruction is a commonly performed surgery. Despite the improved technique and understanding of the rehabilitation rationale, the long-term success rate of good or excellent results is 75% to 90%. That leaves 10% to 25% of reconstructed ACLs with unsatisfactory results.

Distal rotational alignment of the Chinese femur and its relevance in total knee arthroplasty.

The rotational alignments of the distal femur in southern Chinese subjects were investigated. Chinese femurs are significantly more externally rotated. This is new evidence to suggest a racial difference in the distal femoral geometry.

How to use cuff suture instruments: the concept of "concave in and concave out".

Arthroscopic reconstructive surgery of the shoulder is extremely demanding. The advent of suture anchors and knot-tying instruments has greatly facilitated its development. Knowledge of the anatomy and surgical principles alone is not enough.

Half-stained thread in shoulder arthroscopy: an improved method of suture management.

Shoulder arthroscopy is used widely to treat a variety of shoulder pathologies. These include various diagnostic and stabilization procedures such as Bankart repair, treating SLAP lesions, capsular plication, and rotator cuff repair. Sutures are commonly used, particularly in stabilization procedures, with or without the use of suture anchors.

Peroneal padding: an alternative to a peroneal post in hip arthroscopy.

Hip arthroscopy is commonly used both to diagnose and treat different underlying hip conditions. It may be performed either by a supine or lateral approach. A peroneal post is commonly used with a fracture table in both the supine and lateral positions to provide lateralization and traction of the femur.

A broken sewing needle in the knee of a 4-year-old child: is it really inside the knee?

We report on a case of a broken needle that migrated inside the knee joint of a 4-year-old girl. Searching for any small foreign body in the knee joint is not easy in either open or arthroscopic procedures. In this case, the surgery was made more difficult because of technical delays and diagnostic difficulties in defining the surgical plane of the needle.

The mini vent technique: a simple method to facilitate accurate secondary portal placement in shoulder arthroscopy.

Accurate portal placement is crucial in diagnostic and therapeutic shoulder arthroscopy. However, knowledge of anatomy and surgical principles may not be enough. Placement of a second portal is often hindered by a small amount of bleeding.

Arthroscopic surgery in the posterior compartment of the knee: Suture fixation of anterior and posterior cruciate ligament avulsions.

Anterior and posterior cruciate ligament avulsion injuries in the posterior compartment of the knee are most commonly dealt with using open approaches. We report an arthroscopic method of treatment using sutures, without the need of any metal implants, that can be safely used in patients with open physes and without the need of a 70 degrees arthroscope.

Why are we still using pre-operative skin traction for hip fractures?

We performed a prospective randomised trial to evaluate the efficacy of pre-operative skin traction for proximal femoral fractures in 311 patients. We found a significant difference in pain score on the evening of admission and the first morning after admission between the groups with traction compared the group without. However, there was no corresponding increase in analgesic requirement during this period.

Congenital anteroposterior spinal dissociation in Larsen's Syndrome: report on two operated cases with long-term follow-up.

Study Design: The outcome of two patients with Larsen's syndrome after spinal surgery was evaluated after follow-up for 9 and 16 years.

Objective: To report on a new phenomenon of anteroposterior dissociation of the vertebrae in Larsen's syndrome. To demonstrate that it can be visualized before surgery with imaging and also seen intraoperatively.

How to overcome severed sutures of the tibial bone peg in anterior cruciate ligament reconstruction.

We report a case of severed sutures of the tibial bone peg during anterior cruciate ligament reconstruction. The graft retracted proximally in the bone tunnel. We describe a simple and aesthetically acceptable method to salvage this rare complication by use of a small arthrotomy through the defect in the remaining patellar tendon.
