Immediate Treatment

1. Reduction of the Dislocation

The first step in treatment is often the reduction of the dislocated tibia. This procedure involves:

• Closed Reduction: This is a non-surgical method where the physician manipulates the knee to realign the bones. It is typically performed under sedation or anesthesia to minimize pain and discomfort[3].
• Open Reduction: If closed reduction is unsuccessful or if there are associated fractures, an open surgical approach may be necessary to realign the bones properly[4].

2. Stabilization

After reduction, stabilization of the knee is crucial to ensure proper healing:

• Immobilization: A knee brace or splint may be applied to immobilize the joint and prevent further injury during the healing process. The duration of immobilization can vary based on the severity of the dislocation and associated injuries[5].
• Weight Bearing: Initially, weight-bearing may be restricted. Gradual reintroduction of weight-bearing activities is typically guided by a healthcare professional[6].

Rehabilitation

1. Physical Therapy

Rehabilitation is a critical component of recovery:

• Range of Motion Exercises: Once the initial healing has occurred, physical therapy will focus on restoring range of motion and strength. Gentle stretching and strengthening exercises are introduced progressively[7].
• Functional Training: As strength improves, functional training may be incorporated to help the patient return to daily activities and sports safely[8].

2. Pain Management

Managing pain and inflammation is essential throughout the recovery process:

• Medications: Non-steroidal anti-inflammatory drugs (NSAIDs) may be prescribed to alleviate pain and reduce swelling[9].
• Ice Therapy: Applying ice to the affected area can help manage swelling and discomfort during the initial recovery phase[10].

Surgical Intervention

In cases where there are complications, such as significant ligament injuries or persistent instability, surgical intervention may be necessary:

• Ligament Repair or Reconstruction: If ligaments are torn, surgical repair or reconstruction may be performed to restore stability to the knee joint[11].
• Arthroscopy: This minimally invasive procedure can be used to assess and treat intra-articular injuries, such as meniscal tears, that may accompany the dislocation[12].

Conclusion

The treatment of lateral dislocation of the proximal end of the tibia (ICD-10 code S83.145) involves a multi-faceted approach that includes immediate reduction, stabilization, rehabilitation, and, if necessary, surgical intervention.
