Brief Summary

This study aims to understand how an early postoperative conventional physiotherapy program affects daily movement and physical function in adults who undergo cosmetic femoral lengthening surgery using the Lengthening Over Nail (LON) technique. Participants aged between 18 and 45 years who have this surgery will take part in a structured physiotherapy program. The study will examine changes in physical function, pain, walking ability, and independence before surgery, during recovery, and after removal of the external fixator. The results of this study may help improve rehabilitation planning after cosmetic femoral lengthening surgery.

Outcome Measures

Primary Outcomes (1)

• Functional Capacity Assessed by the 30-Second Chair Stand Test

  The 30-Second Chair Stand Test is used to assess lower extremity functional strength and overall functional capacity. Participants are instructed to stand up and sit down from a standard chair as many times as possible within 30 seconds. A higher number of repetitions indicates better functional capacity.

  Preoperative baseline, postoperative 8th week, and 1 week after removal of the external fixator

Secondary Outcomes (1)

• Functional Mobility Assessed by the Timed Up and Go Test

  Preoperative baseline, postoperative 8th week, and 1 week after removal of the external fixator

Study Arms (1)

Conventional Physiotherapy Group

EXPERIMENTAL

Participants assigned to this arm will receive a structured conventional physiotherapy program following cosmetic femoral lengthening surgery performed using the Lengthening Over Nail (LON) technique. The rehabilitation program will be initiated in the early postoperative period and will include active and passive joint mobilization exercises, quadriceps and hamstring stretching, isometric muscle strengthening, neuromuscular electrical stimulation (NMES), cryotherapy, and functional mobilization with assistive devices. Physiotherapy sessions will be conducted five days per week under the supervision of an experienced physiotherapist.

Behavioral: Conventional Physiotherapy Program

Interventions

Conventional Physiotherapy Program BEHAVIORAL

The planned rehabilitation program included active and passive joint mobilization, quadriceps and hamstring stretching, isometric strengthening, NMES, cryotherapy, assistive-device-supported ambulation training, elastic-band resistance exercises, and modified apparatus-based Pilates, supervised by a physiotherapist five days per week for 13 weeks. In actual implementation, structured rehabilitation began on postoperative day 7. Daily cryotherapy during postoperative days 0-6 was routine inpatient care and was not part of the study rehabilitation program. Cryotherapy was applied at every supervised session during rehabilitation weeks 1-4 and thereafter only when edema persisted. Superficial thermotherapy was used as supportive physiotherapy when clinically indicated for muscle tightness or stiffness before stretching or mobilization; it was not provided to every participant or at every session.
